Olive Oil Extraction
Gemlik olive contains 20-34% oil. Different preservation techniques (especially irridation) applied to table olives are likely to affect olive oil properties. Therefore, the oil of the table olives was extracted to perform antioxidant activity analyzes in the oil. Olive oils were obtained using a laboratory scale Abencor system (MC2 Ingenierias y Sistemas Sevilla, Spain) equipped with a hammer crusher, malaxer, and centrifuge. Clean and healthy olives (2 kg) were collected. The malaxation temperature was adjusted to 26-30 °C for 30 min. All olive oil samples were filtered and stored under dark conditions in amber glass bottles (100 mL) at 4±1°C temperature.
