【摘要】：以野玫瑰籽为原料,通过复合酶对其进行酶解,对酶解后的物料进行冷榨制取野玫瑰籽油,并对酶解冷榨的工艺参数进行优化。结果表明:最佳酶解工艺参数为酶解温度50.3℃、酶解p H 6.5、加酶量2.1%、酶解时间4.6 h;最佳冷榨工艺参数为物料水分8%、冷榨时间10 min、榨膛温度80℃、榨膛压力35 MPa;在最佳条件下,野玫瑰籽出油率达66.1%;所得野玫瑰籽油主要脂肪酸组成为亚油酸56.80%、油酸33.56%和γ-亚麻酸3.24%,主要理化指标为酸值(KOH)0.84 mg/g、过氧化值5.12 mmol/kg、色泽Y70 R2.6。
[Abstract]:Wild rose seed oil was obtained by enzymatic hydrolysis of wild rose seed with complex enzymes, and the technological parameters of enzymatic hydrolysis were optimized. Under the optimum conditions, the oil yield of wild rose seed reached 66.1%. The main fatty acid compositions of wild rose seed oil were linoleic acid 56.80%, oleic acid 33.56% and gamma-linolenic acid 3.24%. The main physical and chemical indexes were acid value (KOH) 0.84 mg/g, peroxide value 5.12 mmol/kg, color Y70 R2.6.6.
