Soybean phospholipids are a by-product of soybean oil production and are rich in many phospholipid components,such as phosphatidylcholine,phosphatidylethanolamine and phosphatidylinositol,which play an important role in maintaining health and promoting normal physiological functions.In recent years,with the increase of people's demand for healthy diet and nutritional supplements,soy phospholipids,as a natural nutrient component,have received extensive attention.However,the study on the extraction process and nutritional characteristics of soybean phospholipids still needs to be further optimized and deepened.Based on this,the importance of the optimization of soybean phospholipid extraction process was described in this paper,and the optimization of soybean phospholipid extraction process and nutritional characteristics were studied for reference.
