| Soybean oil is the main source of dietary oil for Chinese residents and rich in various nutrients. In order to promote the development of soybean oil extraction technology, starting from the basic principle of aqueous enzymatic extraction of soybean oil, the research progress of enzyme screening and activity optimization, enzymatic hydrolysis process optimization, post enzymatic demulsification, and the combination of aqueous enzymatic extraction and other auxiliary methods in soybean oil aqueous enzymatic extraction technology were mainly discussed. In addition, the impact of aqueous enzymatic extraction on the quality of soybean oil was reviewed. Compared with other oilseeds, soybean has a low oil content and a large proportion of proteins inside the cell, making it difficult to extract oil. Through process optimization the extraction rate of soybean oil by aqueous enzymatic method can be effectively improved and the obtained oil has relatively high nutritional value. The aqueous enzymatic method has advantages of mild extraction conditions, low energy consumption, simple and safe operation, conforms the development needs of soybean oil processing industry, and will have greater application space in the industrial production of soybean oil. |
