In addition to fat, soybean oil also contains some non-oil substances during processing. Unrefined crude oil contains 1%-3% phospholipids, 0.7%-0.8% sterols, and a small amount of protein and wheat germ phenol, which are easy to cause rancidity. Therefore, if soybean oil is not hydrated to remove impurities, it is not suitable for long-term storage. In addition, during long-term storage, the color of refined soybean oil will gradually change from light to dark, which may be related to the auto-oxidation of oil. Therefore, when the color of soybean oil becomes darker, it is not suitable for long-term storage.
