中文摘要：

以月见草籽为原料，采用酶法预处理后再压榨的方法制取月见草油，先用复合酶（复合多糖酶、植物水解酶、纤维素酶比为4：1：1）对月见草籽进行前处理，通过单因素和正交试验确定最佳酶解条件为酶解温度50℃、酶解pH5．0、酶用量2％、酶解时间5．5h，在此条件下游离油得率24％，然后将含油物料烘干后调整水分至9％，以60℃为初始入榨温度进行压榨，最后得出在压榨温度90℃、压榨压力3．5MPa时，出油率可达69％。制取得到的月见草油中的γ-亚麻酸以及亚油酸等不饱和酸被很好的保留，油脂品质良好。

英文摘要：

In this work, evening primrose oil was pressed from enzymatically pretreated samples of evening primrose seeds. The enzymatic pretreatment was carried out using a mixture composed of a commercial complex enzyme preparation hydrolyzing carbohydrates, viscozyme and cellulase （all from Novozymes, 4：1：1）. By using one-factor-at-a-time and oithogonal array design methods, the optimal enzymatic pretreatment conditions were determined to be hydrolysis for 5.5 h at 50 ℃, initial pH 5.0 with a total enzyme dosage of 2%. Under these conditions, the yield of free oil was 24%. The pretreated material was dried until the moisture content reached 9%, and then pressed initially at 60 ℃, finally at 90 ℃ and 3.5 MPa, resulting in an oil yield of 69%. γ-Linolenic, linoleic and some other unsaturated fatty acids were retained at significant levels in the evening primrose oil, and the oil quality was good.
