The Effects of Different Extraction Methods on Antioxidant
Methods of extraction of seed oils are an effective factor in the properties of oils. Solvent extraction, for example, is deficient in selectivity and needs extreme heat, which could cause the degradation of the desired components . The cold press extraction is the conventional method for oil extraction.
Neem seed oil can be obtained by solvent extraction of the Neem seed, fruit, oil, cake or kernel. A large industry in India extracts this oil remaining in the seed cake using hexane. This solvent-extracted oil is of lower quality as compared to the cold pressed oil and is generally used for soap manufacturing.
A Review of Methods Used for Seed Oil Extraction
large scale oil extraction is intended. It is hoped that this review would be useful to stakeholders in seed oil prospecting and exploitation, notably oilseed researchers and oilseed processors, in selecting the most suitable methods of oil extraction. Keywords: Seed oil, extraction, methods, yield, quality 1. Introduction
Extracting of Oil From The Seed. This process is known as cold pressing. For most oils however, the process is more complex. Modern oil mills extract oil using a combination of pressing, cooking and solvent extraction. This process is often carried out in the country of origin.
Solvent Extraction Method for Edible Oil Processing
Solvent extraction is a chemical oil extraction method to process oil out from vegetables, oilseeds and nuts by solvent, and Hexane is the preferred choice. Industrial oil processing for the edible oil generally involves the solvent extraction step which may or may not be preceded by pressing.

what is the role of solvent-Hexane in extraction plant seeds?
The cake from oil press section could also be used as raw material for solvent extraction plant, the chemical way to extract oil. This kind of extraction uses chemical solvent (LIke Hexane )to dissolve oil content contained in cake or oil seeds. Oil is collected by vaporizing solvent out which is later recycled.
