The traditional method of olive oil extraction is by using an olive press. The main advantages of the traditional method are that it produces good-quality oil by more efficient grinding of the olives, reducing the release of oil oxidation enzymes, and that it also reduces added water, which minimize the washing of polyphenols. The modern method ...

In this Argan oil extraction method, the women sit armed with a base rock and a hand-held sharp stone to start over the extraction process. They crack each Argan fruit shell open in a very cumbersome, time- and effort-consuming process to reach the Argan oil-rich kernels. These are then roasted to lightly bring out the flavor and let aside to cool down before they are ground using a

Mechanical methods: An oil press is the simplest available method to press the dry biomass to extract oil. Oil presses are successfully used for the extraction of oil from crop seeds (e.g., sunflower, canola, and olives). In the case of algae, the biomass requires drying prior to pressing it through the press, which is a significant cost making this option less cost-effective.
