The NSW Department of Primary Industries’ (DPI) Wagga Wagga Edible Oils Laboratory - a cornerstone of Australia’s olive and oilseed testing infrastructure - is expected to cease operations by Christmas 2025, with sample submissions accepted only until mid-November. The closure represents a significant loss for growers, processors, and exporters who have relied on the lab’s internationally accredited testing services for more than two decades.

Thinking about making your own olive oil? This guide from The Olive Centre explains what beginners must understand before starting. Budget machines under $10,000 often fail to produce real extra virgin olive oil, which requires proper crushers, malaxers, and decanters. The article covers each stage of extraction, from breaking down olive pits to controlled malaxation and centrifugal separation.

Extra virgin olive oil (EVOO) owes much of its flavor, nutrition, and shelf life to the way it is extracted. One of the most critical steps in this process is adjusting the decanter centrifuge, a machine that separates oil from olive paste. This article explores how key settings—such as the choice between two-phase or three-phase systems and the differential speed (Dn) between the drum and screw—directly shape the quality of olive oil.

Efficient and high-quality olive oil extraction depends on fine-tuning multiple process variables. Below are critical control points and potential adjustment areas within modern olive oil production systems:

For businesses and serious growers considering olive oil extraction, the idea of owning a machine for under $10,000 may seem like an attractive entry point. However, achieving high-quality olive oil requires advanced extraction technology that meets food-grade standards. The extraction process is highly technical, demanding specialised equipment to maintain oil integrity and efficiency. This guide will help you understand the essential components
