Soyabean Refinde Oil

soyabean vegetable oil is a vegetable oil extracted from the seeds of the soybean. It is one of the most widely consumed cooking oils. As a drying oil, processed soybean oil is also used as a base for printing inks and oil paints.soybean seeds compose about 18-20% of extractable oil by weight. The seeds are then subjected to pressing oil and the residue soybean meal is used as animal feed. Crude soybean oil is deep yellow and contains impurities such as moisture, lecithin, free-fatty acids, and certain volatile compounds. These impurities are then removed through further refining to obtain acceptable standard cooking oil. Refined oil is clear light yellow liquid, and features neutral odor and taste. Fresh oil has very low free fatty acids (FFA) less than 0.1%. Its specific gravity @ 25 °C is 0.9150–0.9280, Iodine value-75 – 94, and saponification value-184 – 195.
