【摘要】:以野玫瑰籽為原料,通過復(fù)合酶對其進行酶解,對酶解后的物料進行冷榨制取野玫瑰籽油,并對酶解冷榨的工藝參數(shù)進行優(yōu)化。結(jié)果表明:最佳酶解工藝參數(shù)為酶解溫度50.3℃、酶解p H 6.5、加酶量2.1%、酶解時間4.6 h;最佳冷榨工藝參數(shù)為物料水分8%、冷榨時間10 min、榨膛溫度80℃、榨膛壓力35 MPa;在最佳條件下,野玫瑰籽出油率達66.1%;所得野玫瑰籽油主要脂肪酸組成為亞油酸56.80%、油酸33.56%和γ-亞麻酸3.24%,主要理化指標為酸值(KOH)0.84 mg/g、過氧化值5.12 mmol/kg、色澤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.
