摘　　要：选取索氏提取法、超声波辅助萃取法、冷榨法,与水酶法作比较,研究不同方法提取小麦胚芽油的提油率和油脂品质,综合评价不同方法的优缺点。结果表明:相对于其他3种方法,水酶法提取小麦胚芽油具有较高的提油率、优良的理化指标和V_E含量,并且水酶法绿色无污染,适合用于高品质小麦胚芽油的提取。Soxhlet extraction, ultrasonic assisted extraction, low temperature pressing method and aqueous enzymatic were selected to study oil extraction rate and oil quality of wheat germ oil extracted in different methods. The results were as follows： comparing to other three methods, the higher yield occurred by aqueous enzymatic method, and the better physical and chemical characteristics and higher contents of VE. Furthermore,aqueous enzymatic method was considered as a green method without any pollution to gain wheat germ oil with a high quality.
