以新疆布尔津县沙棘原浆为原料,采用酶解法提取果油,对提取条件进行单因素分析和正交实验,确定了果油提取适宜工艺参数:果胶酶用量0.5%,胃蛋白酶用量0.08%,酶解温度55℃,酶解时间6h,此条件下的果油得率为1.9875%。利用剩余沙棘果汁制作沙棘浊汁饮料和沙棘清汁饮料,即浊汁饮料配方为:沙棘原汁为20%,蔗糖11%,羧甲基纤维素(CMC)0.3%,黄原胶0.03%;清汁饮料配方为:沙棘原汁60 mL,蔗糖14%,纯水150 mL,Vc含量0.2%。

Extraction of oil from bu er jin seabuchthorn pulp and its process technology of beverages were investigated.Through the single factor experiment and the orthogonal experiment,the optimal extraction conditions were determined: the amount of Pectinase was 0.50%,Pepsin was 0.08%;temperature was 55℃;and the extracting time was 6 h.Under these conditions,the oil extraction rate is up to 1.9875%.And the residue was used to product clear juice or turbid juice.The optimal formula of turbid juice were as follows: seabuckthorn puree 30%,sugar 14%,CMC 0.3%,Xanthan gum 0.03%.And the optimal ingredient of the clear juice were: seabuckthorn puree 60mL,sugar 14%,water 150mL,Vc 0.2%.
