A reliable and practical choice for olive packaging and broader food industry applications.
What are the benefits of using square pails instead of round pails for food packaging?
Square pails provide significant advantages over round containers in food packaging and distribution. The square design allows for more efficient use of space, reducing voids during stacking and palletisation. This directly translates into lower storage and transport costs, especially for bulk products like olives.
From a production standpoint, square pails are just as versatile as round ones, accommodating hot or cold filling. They are also easier to arrange in storage facilities, creating a more organised and space-efficient system.
Key benefits of square pails include:
For commercial packers of olives and other foods, square pails offer an efficient, hygienic, and cost-effective packaging solution.
In the pursuit of advancing olive oil quality, a groundbreaking development for the industry has emerged from a recent study that has illuminated how specific compounds — particularly secoiridoids — can substantially improve the oxidative stability and shelf life of ‘Corbella Extra Virgin Olive Oil (EVOO).
The collaborative Spanish study, carried out at an industrial mill, centered on assessing the influence of malaxation conditions and olive storage on the composition of ‘Corbella’ EVOO, offering insights with potentially transformative implications for the sector.
Extra Virgin Olive Oil is celebrated worldwide for its health-promoting properties and distinctive flavor, establishing itself as a culinary cornerstone across cultures. Nevertheless, its oxidative stability — a key factor in determining shelf life and overall quality — has long been the focus of intensive research. This latest investigation has presented compelling evidence that certain compounds play a decisive role in reinforcing EVOO’s stability.
The principal compounds examined included phenolic compounds, tocopherols, carotenoids, squalene, and fatty acids, all of which are fundamental to the oil’s composition. The findings revealed that extended malaxation at higher temperatures, together with olive storage, negatively affected compounds such as α-tocopherol, squalene, flavonoids, lignans, phenolic acids, and phenolic alcohols. However, paradoxically, both the antioxidant capacity and oxidative stability of the oil improved under these conditions. This enhancement was attributed to a marked increase in the concentration of two secoiridoids: oleacein (56–71%) and oleocanthal (42–67%).
Oleacein and oleocanthal are widely recognized for their potent antioxidant activity, and this study has underscored their critical contribution to reinforcing EVOO’s stability and extending its shelf life. In addition, the research identified a synergistic interaction between secoiridoids and carotenoids, further highlighting their collective role in enhancing the resilience and longevity of EVOO.
Concentrations (mg/kg oil) of squalene, α-tocopherol, β-carotene, lutein, secoiridoids, oleacein, and oleocanthal in ‘Corbella’ Extra Virgin Olive Oil (EVOO) samples O1 and O4, along with the oleic/linoleic ratio, antioxidant capacity (DPPH, µg TE/g oil), and oxidative stability (Rancimat induction time, h). Sample O1 was produced on the day of harvest, while O4 was produced the following day using stored olives. Both EVOOs were malaxed at 18 °C for 30 minutes. Data are presented as mean ± standard deviation (n = 9). All parameters showed significant differences (p < 0.05) between samples.
One of the most notable discoveries was the ‘Corbella’ cultivar’s ability to yield EVOOs with a favorable oleic/linoleic ratio. The research indicated that storing olives overnight at ambient temperature, followed by malaxation at no less than 23 °C for 40–50 minutes (depending on the precise temperature), could substantially elevate the concentrations of oleacein and oleocanthal. This increase, in turn, contributed to a measurable improvement in the oxidative stability of EVOOs.
These findings represent a significant advancement in efforts to address and enhance EVOO stability, offering practical applications for producers aiming to extend shelf life while safeguarding quality.
The study also highlighted several promising avenues for future research. Key areas of interest include identifying strategies to further elevate oleacein and oleocanthal levels through agronomic and climatic variables, fruit maturity, and technological aspects of oil extraction.
Moreover, the evaluation of EVOO quality and stability over long-term storage, together with interventional studies assessing the direct influence of these secoiridoids on both product longevity and human health, remains a critical area requiring deeper exploration.
In summary, the research underscores the pivotal role of secoiridoids — particularly oleacein and oleocanthal — in enhancing oxidative stability and extending the shelf life of ‘Corbella’ EVOO. These insights hold dual significance: they offer tangible benefits for producers while also presenting potential health advantages for consumers, marking a milestone in the olive oil industry’s ongoing pursuit of excellence.
