摘要: 三种取汁方法的实验结果表明,制取黑莓果汁采用酶法液化法,出汁率、果汁澄清度、可溶性固形物含量高;直接榨汁法出汁率和可溶性固形物含量较高,但果汁浑浊;浸提取汁法出汁率低,果汁稀薄,可溶性固形物含量低,但色素获得率高。酶解正交试验结果表明,果胶酶用量0.04%~0.06%,处理时间1~2h,处理温度45~55℃,黑莓浆果出汁率高,果汁得率在80%以上,果汁澄清,质量好,果汁透光率在90%左右。

Abstract: Among of three different juice processing technics, the juice yield, the effect of defecating and the soluble solids concentration (SSC) of the syrup by enzyme-liquefaction are all higher; The juice yield and SSC of the syrup by direct pressing are higher but the syrup is thick; The juice yield and the SSC of the syrup by leaching is lower and the is thin, get more pigments are obtained. The enzyme-liquefaction orthogonal test showed that the juice yield of blackberry is beyond 80%, the effect of defecating is good, and the transparence is about 90% with 0.04%~0.06% pectinase under the temperature 45~55 ℃ for 2 h.
