Solvent Extraction of Oil and It's Economy

The processing of oilseeds and oil containing fruits becomes vital because the people need more and more oil for human nutrition and also for technical applications. There are three different methods for the extractions of oil are conceivable: (1) pressing (2) extraction by solvent and (3) Pressing followed by solvent extraction. Pressing is a very old method which is replaced by the use of solvent which is more efficient, especially for oilseeds with lower oil contents such as soybeans. Seeds with higher oil contents are pre-pressed before extraction by solvent. We discussed the different aspects of oil processing of the raw material via extraction either by pressing or solvent extraction. We discussed Factors Influencing the Extraction Efficiency, Choice of solvent, Separations of Solvent and Oil, Relative Yields and Advantages of solvent extraction. Oil extraction process which we are going to use it increases the yield of oil %. We also studied Edible Oil Production and Consumption, Indian vegetable oil economy.
