摘要： 以显齿蛇葡萄籽为原料,通过单因素试验和响应面分析法对水酶法提取显齿蛇葡萄籽油的工艺进行研究。结果表明,水酶法提取显齿蛇葡萄籽油的较佳工艺为:液料比(mL/g)为12.6,中性蛋白酶的质量分数为1.4%,酶解温度为52.0 ℃,酶解时间为3.2 h,此条件下显齿蛇葡萄籽油提取率达到10.30%。以大豆分离蛋白和麦芽糊精为壁材,通过正交试验对显齿蛇葡萄籽油微胶囊化的工艺进行研究。结果显示,显齿蛇葡萄籽油微胶囊化的较佳条件为:壁材的质量分数为13%,芯材壁材质量比为1∶6,喷雾干燥器进、出风口温度分别为125和62 ℃,均质压力为28 MPa,此条件下显齿蛇葡萄籽油微胶囊化包埋率为92.3%。

Abstract: Ampelopsis grossedentata seed oil was extracted from Ampelopsis grossedentata seed as raw material by aqueous enzymatic method.Process conditions were identified by single factor experiment and response surface methodology.Results showed that the optimum extraction conditions of Ampelopsis grossedentata seed oil are as follows:ratio of solution to raw material (mL/g),12.6;dosage of neutral protease,1.4%;enzymolysis temperature,52.0 ℃;enzymolysis time,3.2 h.Extraction yield of Ampelopsis grossedentata seed oil reaches 10.30%.With protein isolated from soybean and malt dextrin as the wall materials,the microencapsulation conditions of Ampelopsis grossedentata seed oil were examined by orthogonal experiment.Results showed that the optimum microencapsulation conditions are as follows:mas fraction of wall material,13%;mass ratio of core material to wall material,1∶6;spray dryer inlet air temperature and outlet air temperature,125 and 62 ℃ respectively;homogenizing pressure,28 MPa.Under these conditions,microencapsulation ratio of Ampelopsis grossedentata seed oil achieves 92.3%.
