The difference between the two: soybean oil: it is a relatively pure oil produced by pressing and other processes. The purity and quality are divided into three grades, and the first-grade soybean oil is the top grade. Edible blending oil: generally blended with inferior oil and additives, but it can also be divided into several grades. If the materials are good, the quality of the finished product will be good. There is no doubt that pure soybean oil is superior to blended edible oil. Just like brewing liquor and blending liquor (also called blending liquor), its processing technology and quality are completely different.
