Harbin Zhongan foolishly pumped soybean oil for several years, which is a business model. When soybean oil was madly leached, many small stupid oil mills closed down one after another. In a relatively stable period, Zhongan adopted the practice of returning to nature and satisfying tradition, making itself grow and develop.
Stupid pressing is just a concept, because pure stupid pressed soybean oil can't meet the national standard. If it is refined, the previous technological characteristics will be gone. Therefore, many stupid squeezing plants are more or less mixed leaching soybean oil to reduce costs. From the safety point of view, the quality of soybean oil in Zhongan can still be guaranteed, so enjoy it.
Crude soybean oil contains a lot of linoleic acid, which is an essential fatty acid for human body and has important physiological functions. Children lack linoleic acid, the skin becomes dry, the scales become thick and grow slowly, and the elderly lack linoleic acid, which will cause cataracts and cardiovascular and cerebrovascular diseases.
The beany smell of soybean oil is caused by linolenic acid and linolenic acid. When the content of linolenic acid is minimized by selective hydrogenation and the formation of linolenic acid is avoided, the "aftertaste" phenomenon of soybean oil can be basically eliminated. When refined soybean oil is stored for a long time, its color will change from light to dark, which is called "color recovery".
