Research into olive oil Storage

Research into olive oil storage

In a world-first, Industry & Investment (I&I) NSW scientists are exploring how long olive oil can be confidently stored and still taste great. The Rural Industries Research and Development Corporation funded project aims to enhance the science which predicts the shelf life of olive oil.

I&I NSW principal research scientist Dr Rod Mailer said that although the tests to predict oil shelf life exist, this project is taking the chemistry a step further.
"We're already testing oil to authenticate that it is extra virgin olive oil, now we're looking at the factors which cause oil to oxidise and recording the reactions of a range of oils during the three-year project," said Dr Mailer.
"The chemical composition of each oil has been analysed and we are exposing them to light, temperature and oxygen all of which cause oxidation," he added.

Oxidation eventually produces offflavours and bad odours in oil and the aim of the project is to identify how to extend oil stability so that the fruity olive oil flavour lasts longer. Dr Mailer said that oils with high levels of polyphenols, which are antioxidants, and low levels of polyunsaturated fatty acids can last 18 months or two years.

"Some of these oils made from younger, early-harvest olives have a pungent, bitter flavour which is not popular with some consumers and while oils from older olives taste mellow they
may have a shorter shelf life," he said.

"The research is examining how to get the best of both worlds. We can take oil which is high in antioxidants with a stable fatty acid profile and blend it with less pungent, softer oil to produce a mellow, fruity-tasting oil with an increased shelf life," he added.

Crop management, olive variety and harvest techniques also impact on how long oil will last.

"The amount of water trees get during the growing season also affects shelf life water-stressed trees produce more polyphenols resulting in pungent, longer lasting oil," he concluded.

Sansone Premium Stainless Steel Tanks Built for Global Best Storage Practices

PREMIUM STORAGE TECHNOLOGY

Sansone Premium Stainless Steel Tanks Built For Quality Preservation With Global Best Storage Practices

Preserving the integrity of high-quality foods and liquids - especially extra virgin olive oil (EVOO) - depends on two things: a sound understanding of correct storage parameters and the use of vessels engineered to uphold those conditions with absolute reliability. This is where Sansone, Italy’s premier stainless-steel tank manufacturer, stands far above conventional storage solutions. As global quality standards evolve, the industry has moved decisively away from breathable plastics & reactive metals. With increasing focus on purity, sustainability, and product shelf-life, food-grade stainless steel has become the internationally accepted gold standard for storing oils, beverages, ferments, honey, pharmaceuticals, and more. Within that space, Sansone’s range - distributed in Australia by The Olive Centre - has set the benchmark for durability, hygiene, and performance for over five decades.


Why Sansone Tanks Are the Ideal Match for Best-Practice Olive Oil Storage

International Olive Council (IOC) guidelines highlight the key threats to olive oil quality, i.e. oxygen, light, and heat, each of which accelerates oxidation and rancidity. Proper storage must therefore minimise air contact, prevent light exposure, and maintain stable, cool temperatures. 


Sansone’s engineering and material choices align perfectly with these requirements:

1. Oxygen Protection: Airtight Design & Minimised Headspace

The IOC highlights that once a container is opened, limiting headspace is essential to slow oxidation.

How Sansone supports this:

  • Hermetic seals on lids, clips, and o-rings prevent oxygen ingress.
  • Precision-machined threads on taps ensure no micro-air leaks.
  • Many models come in incremental sizes, enabling producers and consumers to select volumes matching 1 - 3 months’ usage - the exact timeframe recommended by the IOC.
  • Large containers allow for decanting into small stainless steel units, which the IOC recommends for preserving quality once larger cans are opened.
2. Light Protection: Stainless Steel as an Opaque Barrier

The IOC identifies light as the main threat to olive oil quality after oxygen.

Sansone’s advantage:

  • Full stainless-steel construction completely blocks UV and visible light.
  • Mirror-polished interiors resist residue buildup, ensuring no photoreactive particles remain on surfaces between batches.
3. Temperature Stability: Thermal Protection & Structural Integrity

The IOC recommends storing olive oil between 13 - 25°C, and notes that lower temperatures (even refrigeration) can slow oxidation.

Sansone excels in temperature resilience:

  • High-grade AISI 304 (18/10) or AISI 316 steel (optional) maintains structural integrity regardless of ambient fluctuations.
  • No warping, cracking, or polymer breakdown (common with plastic).
  • Suitable for cold storage without material fatigue or risk of flavour contamination.
4. Hygiene & Safety: The Foundation of Sansone’s Philosophy

The IOC emphasises cleanliness, inert materials, and contamination avoidance.

Sansone tanks surpass these needs through:

  • AISI 304 stainless steel for all food-contact surfaces; AISI 316 (optional) available where higher corrosion resistance is required (e.g., acidic ferments, saline solutions).
  • Mirror-polished interiors prevent residue, microbial growth, or flavour carryover.
  • Fully weld-sanitised or precision-seamed joins engineered for long-term purity.
  • NSF-certified taps available on select models.
Whether storing EVOO, honey, wine, ferments, kombucha, tinctures, cosmetics, or nutraceutical extracts, Sansone containers guarantee an inert environment that preserves product integrity.


5. Durability & Long-Term Value: Sustainability Meets Performance

Stainless steel is durable, corrosion-resistant, and 100% recyclable - maintaining its quality through multiple recycling loops. Sansone’s robust construction means a single tank can last decades, dramatically reducing lifecycle costs compared with plastics or coated metals. Their longevity also prevents product loss due to leaks, contamination, or light-induced degradation, making Sansone an economically and environmentally superior investment for producers of all scales.

Comparison Chart: Plastic vs Stainless Steel vs Glass Containers

Criteria Plastic Containers Stainless Steel Containers (e.g. Sansone) Glass Containers
Material Reactivity It can leach plasticisers over time, especially with acidic or fatty products. Completely inert; AISI 304/316 food-grade steel prevents reactions. Inert to most liquids but may interact with extreme pH.
Light Protection Allows light penetration unless opaque. 100% light-proof - ideal for olive oil and sensitive liquids. Transparent unless tinted; light accelerates oxidation.  Coloured glass can slow down light penetration.
Oxygen Protection / Seal Quality Moderate; lids may warp or expand, increasing oxygen exposure. Excellent - airtight seals and precision threads limit oxygen exposure. Good initially, but seals vary; headspace increases quickly once opened.
Durability Prone to warping, cracking, and UV degradation. Extremely durable - decades of use without deforming. Fragile; breaks or chips easily.
Temperature Resistance Sensitive to heat; may warp or release BPA-like compounds/plasticisers. Highly stable across temperature ranges, including refrigeration and warm environments. Stable but expands/contracts; risk of thermal shock.
Hygiene & Cleanability Scratches retain residues and microbes; absorbs odours. Mirror-polished surfaces prevent buildup; no odour retention; easy sanitation. Very hygienic but difficult to clean if narrow-necked.
Impact on Olive Oil Quality Can accelerate oxidation; not recommended by IOC for long-term storage. Ideal - protects from light, heat, and oxygen; aligned with IOC guidelines. Good if dark/tinted and stored cool, but still sensitive to light exposure.
Sustainability Limited recyclability; degrades in quality each cycle. 100% recyclable without quality loss; extremely long lifespan. Highly recyclable but higher breakage rate.
Weight Lightweight. Moderately heavy (depending on tank size). Heavy and cumbersome, especially in larger volumes.
Cost (Upfront) Low Higher initial investment Moderate cost
Cost (Lifecycle) High - due to frequent replacement and product spoilage risk. Low - one tank often lasts decades; prevents losses from contamination or oxidation. Moderate - replacement due to breakage or seal failure.
Suitability for Industrial Use Poor - short lifespan and limited hygienic control. Excellent - used in olive oil production, wineries, pharmaceuticals, honey, and beverage industries. Limited - weight and fragility restrict large-volume use.
Suitability for Long-Term Food Storage Not recommended. Excellent - best long-term solution for oils, ferments, beverages, and extracts. Acceptable for short-to-medium term if protected from light.

Extra Virgin Olive Oil: A Comprehensive Guide for Australian Consumers

CONSUMER EDUCATION

Extra Virgin Olive Oil: A Comprehensive Guide for Australian Consumers

Extra Virgin Olive Oil (EVOO) is often hailed as a “liquid gold” in kitchens around the world – a term famously used by the ancient Greek poet Homer. For Australians, EVOO is more than just an ingredient; it’s a heart-healthy cooking staple and a link to centuries of Mediterranean tradition. This guide will explain exactly what EVOO is and how it differs from other olive oils, how it’s produced (from grove to bottle), its science-backed health benefits, and the many ways you can use it – both in your cooking and beyond. Along the way, we’ll share some interesting facts that highlight why this oil has been prized since antiquity. Let’s dive in! 

What Is Extra Virgin Olive Oil (EVOO)?

Extra Virgin Olive Oil is the highest grade of olive oil, essentially the fresh “juice” of the olive fruit. It is obtained purely by mechanical means (crushing and pressing/centrifuging olives) without any chemicals or excessive heat. To qualify as EVOO, the oil must meet strict standards: free acidity of ≤0.8% (a measure of oleic acid) and no sensory defects in taste or aroma. In other words, a true EVOO tastes and smells fresh and pleasant (often fruity, grassy, or peppery) and is very low in free fatty acids. This minimal processing also means EVOO retains more of the natural antioxidants, vitamin E and plant phytosterols from the olives.

By contrast, other grades of olive oil are lower in quality or more processed: 

  • Virgin Olive Oil (VOO): Also made by mechanical means with no chemicals, but comes from riper or lower-quality olives. It can have up to 2.0% acidity and slight taste defects, making it a lower grade than EVOO. Virgin olive oil is less common on supermarket shelves, as most high-quality production is sold as EVOO. 
  • “Olive Oil” or “Pure/Light” Olive Oil: These commonly labelled supermarket oils are typically blends of refined olive oil and a bit of virgin oil. Refined olive oil starts as lampante (lamp oil) grade – oil from defective or over-ripe olives – which is then put through industrial refining (using methods like filtering, deodorising, high-heat treatment) to remove impurities and off-flavours. The result is a neutral-tasting oil with very low acidity, which is then mixed with a small amount of virgin olive oil to give it some olive flavour. These oils lack the rich flavour and many of the antioxidants of EVOO because refining strips away most polyphenols and nutrients. Note: Terms like “Pure,” “Light,” or “Extra Light” olive oil are marketing terms for refined oils – not lower-calorie oils. In fact, Australian standards don’t permit “Extra Light” on labels because it can mislead consumers; “light” just refers to lighter flavour, not less fat or calories.
  • Olive-Pomace Oil: After the first pressing, the leftover olive pulp (pomace) still contains some oil. Lower-grade producers use solvents to extract this last bit, then refine it. The result, “olive pomace oil,” is an even more processed product used in some commercial frying or food manufacturing. It’s not allowed to be called olive oil under Australian standards, and it lacks the health attributes of EVOO.

In summary, EVOO stands apart from other olive oils because it’s unrefined, of top sensory quality, and packed with natural compounds. If you drizzle a good EVOO on a salad or taste it on a spoon, you’ll notice a bright, complex flavour – something you won’t get from the flat, one-note taste of refined “olive oil” blends. 

How Extra Virgin Olive Oil Is Produced 



EVOO’s journey from tree to bottle is a fascinating combination of ancient tradition and modern food science. It all starts in the olive groves. Olives destined for high-quality EVOO are often hand-picked or gently shaken off trees (modern farms may use mechanical harvesters that vibrate the trunks or use catching frames). The timing of harvest is crucial: early in the season, when olives are green to purplish, they yield less oil, but it’s very rich in flavour and antioxidants; later harvest (ripe black olives) yields more oil but with mellower taste. Many premium Australian producers, much like those in the Mediterranean, opt for early harvest to maximise quality.

Once picked, speed is key – olives are quickly transported to the mill, because freshly harvested olives start to oxidise and ferment if they sit too long. Ideally, olives are pressed within 24 hours of harvest to prevent quality loss. At the mill, the olives are washed to remove leaves and dust, then crushed (pits and all) by either traditional stone mills or modern steel crushers. This creates an olive paste, which is then gently malaxed (slowly churned) for 20–45 minutes. Malaxation allows tiny oil droplets to coalesce, but it’s done under strict temperature control – this is where the term “cold-pressed” or “cold extraction” comes in. To qualify as cold-pressed, no heat above 27 °C is applied during extraction. Keeping the paste cool preserves aromatic compounds and nutrients; higher temperatures could extract a bit more oil, but at the cost of flavour and antioxidants. Australian and European producers alike adhere to this, as heat can reduce EVOO’s polyphenols and vitamin E (and increase oxidation)



A Roman-era olive oil press in Capernaum, Israel. Ancient presses used large millstones to crush olives, and the oil was separated by gravity. Today, modern cold-pressing uses centrifuge extractors, but the goal remains the same – to physically squeeze oil from olives without chemicals or high heat, preserving quality. (photograph of a Roman-era olive mill in Capernaum)   


After malaxation, the paste is pressed or, more commonly, centrifuged. Modern mills use a decanter centrifuge, which rapidly spins the olive paste to separate oil from water and olive solids. The result is fresh olive oil (plus some vegetable water). The oil may then be filtered or simply left to settle so that tiny particles and moisture drop out over time. Some artisan oils are unfiltered, yielding a cloudy appearance, but most commercial EVOOs are filtered for clarity and stability. Finally, the oil is stored in stainless steel tanks (ideally with minimal air exposure) and later bottled. 

Throughout production, maintaining quality is paramount. At no point are solvents or refining used – EVOO is purely a natural juice. This careful process explains why EVOO is more expensive than generic cooking oil: it takes a lot of olives and care to produce. In fact, it typically takes around 4 to 6 kilograms of olives to cold-extract just 1 litre of EVOO (for some early harvest oils, even more). That represents roughly 8000–10,000 individual olives in each litre of premium oil! Such figures help us appreciate the effort and agricultural value inside each bottle of EVOO.

Australian EVOO note: Australia may be far from the Mediterranean, but it has a burgeoning olive oil industry of its own. Olives were first brought to Australia in the 1800s, and the industry remained small until a boom in the late 20th century. The Australian olive industry is over 150 years old, but it has expanded rapidly across all mainland states in recent decades. Today, Australia produces high-quality EVOOs, particularly in regions with Mediterranean-like climates (such as parts of South Australia, Victoria, and Western Australia). Aussie EVOOs often win awards for their robust flavours and purity, thanks to modern farming and milling techniques. So when you shop, know that some EVOO on the shelf – in addition to imports from Italy, Spain, Greece, etc. – is grown and pressed right here in Australia. 

Proven Health Benefits of EVOO 







Extra Virgin Olive Oil isn’t just a tasty fat – it’s exceptionally good for you. Its health benefits are backed by a wealth of scientific research and have even been recognised by international health authorities. Here are some of the top evidence-based benefits:

  • Heart Health & Cholesterol: Replacing saturated fats (like butter or ghee) with EVOO can significantly improve your blood lipid profile. EVOO is high in monounsaturated fat (oleic acid), which is heart-friendly, but beyond that, it’s packed with bioactive compounds like polyphenols. Studies show that regular consumption of EVOO can lower LDL “bad” cholesterol levels while raising HDL “good” cholesterol. Even a relatively small daily intake (for example, 15–20 mL, about a tablespoon) has measurable benefits on cholesterol. The Australian Heart Foundation also recommends olive oil and other unsaturated fats as part of a heart-healthy diet, noting they can improve cholesterol levels and reduce blood pressure when used in place of saturated fats. In fact, populations adhering to a Mediterranean diet rich in EVOO have lower rates of heart disease. One long-term study found that people who used just half a tablespoon or more of olive oil daily had a 19% lower risk of heart disease death compared to those who ate little to none.
  • Lower Blood Pressure: High blood pressure is a risk factor for cardiovascular disease, but EVOO may help keep it in check. Clinical trials have shown diets enriched with EVOO lead to significant reductions in both systolic and diastolic blood pressure over time. Polyphenols in EVOO are thought to improve blood vessel function (endothelial function), helping arteries relax and dilate, which lowers pressure. This blood-pressure-lowering effect is another reason EVOO-based diets (like the Mediterranean diet) are protective for the heart. 
  • Anti-Inflammatory and Antioxidant Effects: Chronic inflammation is at the root of many diseases (heart disease, cancers, arthritis, etc.). EVOO has natural anti-inflammatory compounds. A famous example is oleocanthal, a polyphenol in fresh EVOO that actually mimics ibuprofen! Oleocanthal has a similar mechanism – it can inhibit COX enzymes, which are linked to inflammation and pain, and it’s responsible for the peppery “throat sting” high-quality EVOO often gives. (That little cough you might get from a robust EVOO is literally a sign of its potency; it’s the oleocanthal at work, and indeed it’s been likened to a small dose of anti-inflammatory medicine .) Additionally, EVOO’s plethora of polyphenols (like hydroxytyrosol, oleuropein, etc.) function as antioxidants, protecting your cells and blood lipids from oxidative stress. Research has shown that EVOO-rich diets reduce markers of inflammation in the body. For example, consuming EVOO can lower levels of inflammatory cytokines and oxidation of LDL cholesterol (oxidised LDL is particularly harmful for arteries). In simple terms, EVOO helps “cool down” inflammation and prevents oxidative damage internally, which is a big win for long-term health. 
  • Diabetes and Metabolic Health: EVOO may improve blood sugar control and insulin sensitivity. It’s a key component of the Mediterranean diet, which has been shown to lower the risk of developing type 2 diabetes. For those with diabetes, adding EVOO can help reduce blood glucose spikes and improve HbA1c (a measure of long-term glucose control). One Australian study even found that incorporating EVOO in the diet significantly improved HbA1c levels in people with type 2 diabetes (from 7.1% to 6.8%) and was associated with a 55% relative risk reduction in developing diabetes in a high-risk group. 
  • Other Potential Benefits: Research (mostly observational and some clinical) suggests EVOO consumption is linked with lower incidence of certain cancers, better cognitive function (potentially reducing risk of neurodegenerative diseases like Alzheimer’s), and even improved mood and lower depression rates. While these areas are still being studied, the general finding is that diets rich in EVOO correlate with longer life and lower risk of many chronic diseases. In fact, olive oil consumers in a large study had lower overall mortality (death from all causes) than non-consumers – an impressive testament to how protective EVOO can be as part of a healthy lifestyle.
It’s important to note that many of the benefits above are most pronounced with Extra Virgin (unrefined) olive oil, not the cheaper refined olive oils. The polyphenols and vitamin E that make EVOO so special are largely missing in “pure” or refined olive oils. For example, the U.S. FDA and European Food Safety Authority have acknowledged that consuming polyphenol-rich olive oil (at least 20 g providing ≥5 mg of polyphenols) can protect LDL cholesterol from oxidative damage – but you need genuine EVOO to get those polyphenols. 

Lastly, remember that EVOO is a fat and thus calorie-dense, so use it in place of other fats rather than simply adding on (to balance overall energy intake). But as fats go, EVOO is about the best you can choose for your health. It’s no surprise the Australian Dietary Guidelines and Heart Foundation include olive oil as a core part of a healthy eating pattern, encouraging people to swap butter and animal fats for olive or other plant oils. EVOO isn’t a miracle cure-all, but it is a potent, natural contributor to wellness – and a delicious one at that! 

Culinary Uses: Cooking, Dressing, and Beyond




One of the beauties of EVOO is its culinary versatility. You can use it raw, you can cook with it, you can even bake with it. Here are some popular ways to integrate EVOO into your daily diet, along with tips particularly suited for Australian kitchens: 

  • Salad Dressings and Dips: Perhaps the simplest use – whisk EVOO with vinegar or lemon juice for a quick vinaigrette, or drizzle it straight on greens. A classic combo is EVOO with balsamic vinegar. In Australia, a popular appetiser is fresh, crusty bread dipped in EVOO with dukkah (a spiced nut/seed mix) – a delicious, healthy alternative to butter on bread. You can also drizzle EVOO atop dips like hummus or Greek yogurt tzatziki for extra richness.
  • Cooking (Sautéing, Roasting, Frying): There is a persistent myth that you “can’t cook with extra virgin olive oil” – that it has a low smoke point or will burn. In reality, good EVOO has a moderate to high smoke point, around 190–210   °C (375–410   °F), which is sufficient for most stovetop cooking and oven baking. The average pan sauté is around 120– 150 °C, and deep-frying is ~180 °C, all within EVOO’s range. Extra virgin olive oil’s smoke point varies with quality (lower acidity oils have a higher smoke point), but many EVOOs won’t smoke until over 200 °C. More importantly, EVOO is very stable under heat due to its high antioxidant content and predominantly monounsaturated profile. Studies have shown EVOO to be one of the most stable oils for cooking, producing fewer harmful oxidation products compared to refined seed oils. So feel confident using it to sauté vegetables, stir-fry, pan-sear meats, or roast veggies. For example, toss your pumpkin, potatoes or sweet potatoes in olive oil and rosemary and roast them – they’ll come out golden and flavorful. (Tip: because EVOO is flavorful, its taste will be noticeable in baking; that’s lovely in an olive oil cake or when roasting tomatoes, but for delicate baked goods like scones, you might use a lighter-tasting refined olive oil or half butter/half EVOO.) 




  • Grilling and Marinades: Olive oil is a key ingredient in marinades for meats, fish, or tofu. It helps carry flavours of herbs and spices, and also moistens/protects foods during grilling. Australian barbeques can get an EVOO upgrade: marinate your prawns or chicken in olive oil, garlic, lemon, and herbs before throwing them on the BBQ. Or brush veggies like eggplant and zucchini with EVOO so they grill without sticking and take on delicious char. A drizzle of fresh EVOO after grilling (on steak, fish or even pizza) can also boost flavour – this is called “finishing” a dish with olive oil. 




  • Baking and Spreads: As Aussies look for healthier baking fats, EVOO is a great substitute for butter or margarine in many recipes. You can bake moist olive oil cakes (commonly lemon or orange-scented – a Mediterranean favourite), use EVOO in banana bread, or make pastry crusts with olive oil. Extra virgin oil will impart a slight olive fruit aroma to baked goods, which can be wonderful. Also try olive oil spread: simply mix EVOO with softened butter and a pinch of sea salt, then chill – it creates a creamy spread that has less saturated fat than butter alone. You can even drizzle EVOO on toast with Vegemite or avocado (many Aussies already enjoy avocado toast; adding a splash of good EVOO takes it to the next level of yum and nutrition).




  • Soups and Pasta: In Mediterranean cooking, it’s common to finish soups or stews with a swirl of EVOO just before serving, to add richness and aroma. Try it with pumpkin soup or minestrone. For pasta, instead of heavy creamy sauces, a simple aglio e olio (garlic and olive oil) dressing is delicious – gently fry sliced garlic in EVOO, toss with spaghetti and chilli flakes. Or drizzle EVOO over cooked pasta and grilled vegetables. Basically, think of EVOO as both an ingredient and a condiment – a few drops on top of a dish right before eating can amplify flavour.



  • Storing and Using: Keep your EVOO in a cool, dark place (pantry, not next to the stove) to maintain its quality, as light and heat can degrade it over time. Use it generously but also while it’s fresh – olive oil is best within 1–2 years of harvest (check bottle for harvest or best-by date). Rancid oil loses health benefits and tastes off, so it’s better to buy smaller bottles more frequently than a giant tin that sits for years. Fortunately, Australians are consuming more olive oil than ever – on average around 2 kg per person per year – so your bottle might not last too long anyway! 


Drizzling extra virgin olive oil over a salad of avocado, tomato, and greens. Incorporating EVOO into daily meals can be as simple as using it to dress salads, dip bread, or finish cooked dishes – adding both flavor and healthy fats to the Australian diet.

 

Quick recipe ideas:

  • Breakfast: Sauté mushrooms and spinach in EVOO and serve on wholegrain toast (instead of using butter). Or drizzle olive oil over smashed avocado and feta on toast, with a squeeze of lemon – a nutritious twist on avocado toast.
  • Salad upgrade: Toss roasted beetroot and pumpkin with rocket (arugula), add walnuts and goat cheese, and dress with EVOO + balsamic vinegar. The olive oil helps absorb fat-soluble vitamins from the veggies and makes the salad more satisfying.
  • Marinade: Mix EVOO with Aussie native herbs or lemon myrtle, add garlic and pepper, and marinate fish fillets for 30 minutes before grilling – a heart-healthy dinner. 
  • Oven fries: Cut sweet potatoes into wedges, toss in EVOO, salt, pepper, and paprika. Bake until crispy. You’ll get tasty “chips” without deep frying, and the olive oil aids in browning and adds antioxidants. 
  • Dessert: Try baking an orange and almond olive oil cake. The EVOO gives a moist crumb and a fruity aroma that pairs beautifully with citrus. Search for “Mediterranean olive oil cake” – you’ll find it’s a beloved recipe. 
In all these cases, EVOO isn’t just a passive oil – it actively enhances flavour. Its unique taste can range from buttery to grassy to peppery, depending on the olive variety and harvest. Explore Australian-produced EVOOs too; some are made from single olive cultivars (like Picual or Frantoio) and have distinct tasting notes. Much like wine tasting, you can even do olive oil tastings to appreciate the differences (yes, olive oil sommeliers are a thing!).

Beyond the Kitchen: Non-Culinary Uses for Olive Oil 

Olive oil’s usefulness goes far beyond food. Throughout history, olive oil has been used in daily life in myriad ways – and many of these uses are still relevant or just plain handy today. Here are some nonculinary applications of olive oil: 




  • Skin Moisturiser and Cleanser: Olive oil can work wonders as a natural beauty product. It’s a common ingredient in soaps, lotions, and DIY skincare. You can use a few drops of EVOO as a moisturiser for dry skin or hands, rub it into dry cuticles to nourish nails, or even apply it to chapped lips instead of lip balm. Olive oil is rich in vitamin E and antioxidants, which may help soothe inflammation. (Tip: For a simple exfoliating body scrub, combine olive oil with sugar – it will leave your skin soft .) In fact, the famous Castile soap from Spain is traditionally made from olive oil. Many artisan soap makers and natural cosmetic brands still prize olive oil for its gentle, hypoallergenic properties.




  • Hair Care: If you have dry or frizzy hair, olive oil can come to the rescue. Warm a few tablespoons and use it as a deep conditioning mask – massage into your scalp and hair, leave for 15-30 minutes (you can cover with a shower cap), then shampoo out. It helps add shine and reduce split ends. Just a drop rubbed between your palms can also tame frizz and protect hair ends from damage. Some people also swear by olive oil to treat dandruff or dry scalp, as it has a soothing effect. 




  • Makeup Remover: Olive oil can gently dissolve makeup, including stubborn mascara or theatre makeup. Apply a small amount to a cotton ball and wipe – it will remove makeup while moisturising your skin. Afterwards, wash your face with a normal cleanser to remove the oily residue. This is an inexpensive, natural alternative to commercial makeup removers (just avoid getting it directly in your eyes). 
  • Shaving and Personal Care: Out of shaving cream? Olive oil can act as a shaving lubricant – smooth a thin layer on your skin and shave as usual. It reduces razor burn and leaves skin hydrated. It’s also sometimes used as a massage oil base; mix a bit of olive oil with a few drops of an essential oil (like lavender or peppermint), and you have a lovely massage oil with aromatherapy benefits.



  • Household Uses: Olive oil’s utility extends to the home as well. Have a squeaky door hinge? A tiny drop of olive oil can lubricate it. Need to condition a wooden cutting board or wooden utensils? Food-grade oils like olive oil can be used to season wood (though mineral oil is more commonly recommended since it doesn’t go rancid as quickly). For a quick fix on dried-out wood furniture, you can mix olive oil with a bit of lemon juice and use it as a natural furniture polish – it can restore lustre to wood surfaces. Olive oil can also help remove sticky label glue. Or get gum out of hair by dissolving the stickiness – just be sure to wash the area with soap afterwards.




  • Lamps and Candles: Going truly old-school, olive oil was the lamp fuel of the ancient world. In a pinch, you can actually burn olive oil in certain oil lamps as it’s relatively stable and has a high flash point. Olive oil candles (usually a wick in a container of olive oil) are a DIY project some people use for a cozy, slow-burning light source that doesn’t emit the chemicals that petroleum-based candles might. Fun fact: ancient Mediterranean peoples, including Egyptians and Romans, routinely used olive oil lamps for lighting – it was considered a clean and precious fuel.




  • Historical self-care: The concept of using olive oil for skin and body care isn’t new. The Ancient Greeks and Romans used olive oil like a soap – they would smear it on their bodies and then scrape it off with a strigil (a blunt metal scraper), effectively removing dirt and dead skin. They found that it both cleansed and moisturised the skin. Olive oil was also infused with herbs or perfumes for use as a body oil or hair tonic in many cultures.

As you can see, a bottle of olive oil in the cupboard can double as a mini home remedy kit! One caveat: for non-food uses, you don’t necessarily need to use your finest extra virgin oil – a basic grade or older bottle that you don’t want to cook with can find a second life polishing your coffee table or deep-conditioning your hair. Food-grade olive oil for beauty and home use means you’re avoiding the petrochemicals found in some commercial products, which is a win for those with sensitive skin or who prefer eco-friendly options. 

Interesting Facts and Trivia About Olive Oil 

To round out our EVOO guide, here are some fun facts and bits of trivia that make olive oil even more fascinating:

  • Ancient Prestige: Olive oil has been treasured since antiquity. Besides being “liquid gold” to Homer, it was so valued that in ancient Olympic Games, winners were crowned with olive wreaths, and often awarded amphorae (jars) of top-grade olive oil – a highly prized reward. (In the 2004 Athens Olympic Games, organisers even used branches from a 2,000+ year-old olive tree in Crete to make victor’s wreaths, connecting modern athletes with ancient tradition !)
  • Etymology: The very word “oil” has its roots in olive oil. It comes from Latin oleum, which in turn came from the Greek elaion, meaning olive oil. That’s because for Greeks and Romans, “oil” by default meant olive oil – it was the primary oil they knew. Many Romance languages still reflect this (e.g., olio in Italian means oil, implicitly olive oil). The word “olive” itself traces back to Greek elaia. So when you say “oil,” you’re linguistically invoking olives! 
  • Olive Trees Live for Millennia: Olive trees are amazingly long-lived. They grow gnarled and hollow with age but can survive for many centuries and continue to bear fruit. One famous example is the Olive Tree of Vouves in Crete, Greece, which is estimated to be at least 2,000 years old – and possibly over 3,000 or 4,000 years old, according to some scientists. Incredibly, that tree is still producing olives today! Throughout the Mediterranean, there are numerous “millennial” olive trees. In Croatia, Spain, Italy, and the Middle East, you can encounter trees that were planted around the time of the Roman Empire or even earlier. Talk about resilience! (However, note that exact dating is tough; some recent studies suggest many aren’t quite as old as legend says, but certainly hundreds of years old at least.) Regardless, olive trees symbolise peace and longevity – qualities embodied in their oil as well. 
  • “The Great Healer”: The ancient physician Hippocrates, often called the father of medicine, referred to olive oil as “the great healer.” He prescribed it for various ailments – from soothing skin conditions to helping with pain. Modern science, as we saw in the health section, echoes some of these beliefs in different terms (anti-inflammatory, cardioprotective, etc.). It’s fascinating that over 2,000 years ago, olive oil was recognised for its therapeutic properties. 
  • Olive Oil as Currency: In certain eras, olive oil was so valuable that it functioned like currency. It was a major trade commodity in the ancient world. For instance, in medieval Spain under Islamic rule, taxes were sometimes paid in olive oil because it was considered liquid wealth. The storied prosperity of ancient civilisations like the Minoans and Phoenicians was partly built on the olive oil trade. There’s even a story of the Greek philosopher Thales using knowledge of an upcoming good olive harvest to rent all local olive presses in advance; when the bumper crop came, he made a fortune – essentially an olive oil futures market in the sixth century BC! 
  • Only Cooking Oil from a Fruit: Unlike seed oils (canola, sunflower, etc.), which are extracted from hard seeds often using industrial processes, olive oil is unique in that olives are fruits, and EVOO is a fresh-squeezed fruit juice. It requires simply crushing and separating the natural oil. This is why high-quality EVOO is cloudy when unfiltered and has distinct taste nuances, much like a fruit juice. It also explains why it perishes with time (it’s best when young and fresh). 
  • Smoke Point Misconception: We touched on cooking with EVOO, but it’s an interesting fact on its own: Many people assume you cannot fry in olive oil. In reality, Mediterranean cultures have fried in olive oil for generations (think Spanish churros, Italian fritto misto, etc.), and studies by food scientists have confirmed EVOO’s stability makes it ideal for frying – it resists oxidation better than many refined oils. So the humble fish & chips could be made a tad healthier if fried in olive oil (some fish and chip shops in Australia have started doing this to differentiate their product and because the oil lasts longer in the fryer without breaking down). 
  • Colour is Not a Quality Indicator: Olive oils can range from deep green to golden to pale straw colour. Don’t judge an oil by its colour alone. Some excellent EVOOs are green (often those made from early harvest or certain olive varieties with high chlorophyll), while others are yellow. The flavour, aroma, and chemistry determine quality, not the hue. In fact, professional olive oil tastings use blue or brown tasting glasses so the evaluator can’t see the colour and be biased. So, that old trick of picking the greenest oil isn’t reliable – better to look for quality certifications or awards on labels, or just taste it. 
  • Sediment or Cloudiness: If you see some sediment at the bottom of a bottle of EVOO, it’s likely unfiltered, and those are tiny bits of olive flesh – it’s not a defect per se. In unfiltered oils (also called “olive oil veiled”), the microscopic solids can add extra flavour, though they also shorten shelf life a bit. Most large producers filter oil for stability and appearance, but artisan oils might not be filtered. If you store olive oil in a cool spot, it might even solidify or get cloudy (especially in the fridge), because it contains waxes – this will clear up at room temperature and is not a sign of it being spoiled. 
With these facts, it’s clear that EVOO is not just another cooking oil – it’s a product steeped in history, cultural significance, and nutritional science. Few ingredients check as many boxes: flavour, health tradition, and versatility. It’s no wonder Mediterranean people historically treated olive oil with reverence, and why modern nutritionists sing its praises.

Conclusion

Extra Virgin Olive Oil is truly a kitchen all-star – it elevates our food and supports our health. We’ve learned that EVOO differs from lesser olive oils in quality and production, coming straight from fresh olives without chemicals or refining. We’ve seen how it’s made, preserving its sensory and nutritional treasures. Science shows that incorporating EVOO into your diet can benefit your heart, reduce inflammation, and even help you enjoy your veggies more (because they taste better with a good drizzle!). And beyond cooking, olive oil proves its worth in our beauty routines and households. 

For Australian consumers, the message is embrace EVOO: use it in your salad dressings, swap it for butter when you can, try it in new recipes – both traditional Mediterranean dishes and local Aussie favourites. With Australian olive oil production on the rise, you might even explore home-grown EVOOs, which can be world-class. Remember to store it well, use it generously but mindfully, and appreciate the story behind it – from ancient olive groves to your dinner table. 

In summary, Extra Virgin Olive Oil is more than an ingredient; it’s a lifestyle choice towards better eating and living. So go ahead – enjoy that splash of liquid gold in your meals every day, and taste the difference it makes!

GROWING OLIVES: Research confirms importance of right Olive Oil Storage

When it comes to oil storage you need to consider the impacts on quality in relation to the proposed storage to be used.

This article is about some of the latest research as funded by RIRDC to determine the best storage for your oil.

Remember just because a manufacturer states the container(s) are food-grade doesn't necessarily means they are safe to use for olive oil. ?(All the containers used in this study were regarded as "Food Grade").

Here is a excerpt from the article:

For example, sometimes growers produce oil with very high quality initially, which quickly deteriorates due to the conditions under which it is stored,? he said.

The olive oil can deteriorate so much that it can no longer be classified as extra virgin olive oil, at a huge expense to the growers.

The changes in oil quality described in this report will encourage producers, as well as others in the supply chain of olive oil, to consider the facilities used to store olive oil in order to maintain the high-quality olive oil Australia is increasingly renowned for producing.
