Author(s): K. DHALI AND N. BASAK
Abstract: Oilseeds have formed the backbone of agricultural economies from time immemorial. They are mainly used for edible oil production. Oils are generally plant based lipophilic compounds. Lipids are triglycerides chemically being fatty acid esters of glycerol. Natural antioxidants need to be protected to enhance shelf life of lipids and beneficial effects on human health to enhance the nutritional quality of oil. Extraction of oil is the first step in the refining process. Oils and fats are extracted from their original source using a variety of different methods.

Oil extraction methods ever reported have been discussed in detail here.
