Production Process

Akhisar uslu olive oil is made exclusively from the geographically indicated Akhisar uslu olives. The production process follows strict technical and hygiene standards. Harvested olives are first washed with purified water to remove foreign materials. They are then crushed with water at a maximum temperature of 26 °C. The crushed olives are kneaded into a paste in stainless steel tanks. The consistency and oil yield of the paste are optimized by temperature control, keeping it at 26 °C.

The paste is centrifuged at 3000 rpm to separate olive oil from pomace. The extracted oil is purified from residual water via a second centrifugation. The clean oil is stored in stainless steel or food-grade plastic tanks in a dark environment at 18–22 °C, away from odors that could compromise quality.

After sediment filtration using a clay method, the oil is packaged in glass or tin containers. Products not immediately entering the market are stored in suitable tanks at 20 °C and undergo a final paper filtration to remove sediments before final packaging and sealing.

Packaging and Labeling

Packages must display “Akhisar Uslu Olive Oil” and the Protected Geographical Indication symbol. Logos must cover at least 2/3 of the company mark and be at least 3×3 cm in size. If labels cannot be displayed on the package, the marks must be exhibited visibly in the facility.
