摘要

The purpose of refining vegetable oil is to remove undesirable impurities that affect oil stability,colour,taste and flavour.Physical refining of edible oils has received renewed interest since the early 1970s when the process was reintroduced on a large scale to refine palm oil in Malaysia.The procedure is attractive as the physical refining system results in lower oil loss than chemical refining and also eliminates pollution problems associated with soapstock splitting.Subsequent laboratory and field tests have also shown that physical refining can be used as a substitute for caustic or chemical refining,not only for high free fatty acid (FFA) oils such as palm,but also on low FFA oils such as soybean oil.However,soybean oil has a triglyceride composition rich in monounsaturated and polyunsaturated fatty acids.This makes the oil extremely sensitive to oxidative damage and quality deterioration.In physical refining,the oil degumming and efficiency of the FFA distillation are two very important factors that must be considered to guarantee continuous production of high quality products.
