The evaluation of extraction of some nut oils using screw pressing

Original language description

Today&apos;s consumers prefer low-sugar, low-calorie, natural, and so-called safe products. These trends are also reflected in nuts products and groceries. Globally, the European Union is the largest importing market of edible nuts. Considering the increasing demand for new sources of food, the importance becomes the efficiency of production. This study evaluates the influence of rotation speed in the extraction of almond nut, walnut, hazelnut, cashew nut, and peanut oils using screw pressing. In tested samples, the oil content was on average between 69.14 +-0.79% (walnut) and 46.7 +-1.45% (peanut). From the pressing of oils, it is seen that the oil yield decreased when pressing speed increased (from 30 rpm to 90 rpm, for example in walnut from 0.36 kg to 0.16 kg.h-1) and that the oil sediment yield increased when speed increased (for example in hazelnut nut from 8.51% to 17.37%). The highest amount of oil yields had hazelnut with 3.03 +-0.05 kg.h-1, then walnut with 2.05 +-0.02 kg.h-1, almond nut with 2.34 +-0.05 kg.h-1, peanut with 2.15 +-0.01 kg.h-1, and finally cashew nut with 2.07 +-0.03 kg.h-1.
