Optimization Methods for the Extraction of Vegetable Oils: A
The 225 W microwave power, 15 mL/g solid/liquid ratio, and 20 min extraction time were the optimum conditions necessary to obtain a yield of 87.4% ± 0.44%. The results showed that maximum yields for UAE were obtained in half the time required for microwave assisted extraction (MAE).
7.2.1 Cold Pressed Oil. Nowadays, and comparing with oils obtained by conventional solvent extractions, cold-pressed oils attracted much more worldwide interest thanks to their nutritional and health benefits as well as their richness in bioactive components (Nederal et al. 2012), and leads to an increase in the demand for bioactive compounds of plant origin (Czaplicki et al. 2011).

Pressing Extraction, an overview | ScienceDirect Topics
Screw press for vegetable oil production. through the press, the pressure increases and oil is extracted continuously. The meal will leave the press with up to 20% of the original oil still in it. A second pressing will increase the extraction efficiency, leaving about 5% of the oil in the cake.
There are two categories of vegetable oils as function of extraction and postextraction processes: refined oils as was previously described and virgin oils (Piloto, 2010). The virgin oils are only obtained by mechanical pressing or other physical devices and mainly using cold-pressing, under conditions which do not alter the composition.
Identification of pressed and extracted vegetable oils by
Determination method of pressed vegetable oils. Pressed oils are produced by mechanical pressing without chemical additives and do not contain the solvent used in the extraction method [29, 30]. However, some lubricants of the squeezing machine parts contain the main components of the No. 6 solvent, as observed in a previous study [14].
Amaranthus hybridus is a vegetable which is eaten in Congo Brazzaville and in other countries. Two varieties of A. hybridus seeds (var 1 and 2) were selected for this study. Average oil content varies between 11 and 14%. A. hybridus seeds are also rich in proteins (17%) and minerals. Red oils obtained have a high saponification value (130-190
