摘要: 本文对澄清型石榴山楂复合果汁饮料的加工工艺进行了研究。单因素试验结果表明,利用石榴汁与山楂汁质量比为 4:1的混合果汁作为石榴山楂复合果汁饮料加工原料,可以使复合果汁感官品质最好。以透光率为指标,比较硅藻土、果胶酶和壳聚糖三种澄清方式对复合果汁的澄清效果,结果表明,果胶酶澄清方式效果最好,壳聚糖次之,硅藻土最差,且果胶酶澄清后的复合果汁稳定性最好,壳聚糖和硅藻土澄清后的复合果汁稳定性较差。通过正交试验优化复合果汁澄清工艺,结果表明,添加质量分数为008%的果胶酶,酶解温度为45 ℃,酶解时间为15 ~ 20 h,复合果汁澄清效果最好。

Abstract: We address the processing technology of a clarified pomegranate and hawthorn compound fruit beverage. Single factor experiment shows that the sensory quality of the compound juice is optimal for the mass ratio of pomegranate juice and hawthorn juice of 4:1. We compare three clarifying methods such as diatomite, pectinase and chitosan with transmittance as an index. Results demonstrate that the clarifying effect gradually decreases for pectinase, chitosan and diatomite. The storage stability of the compound juice clarified by pecinase is better than that clarified by diatomite and chitosan. Orthogonal test is employed to optimize the clarifying process. Results indicate that the clarifying effect of the compound juice is best under the conditions of the pectinase amount of 0.08%, enzymatic hydrolysis temperature of 45℃ and enzymatic hydrolysis time of 1.5 ~ 2.0 h.

Key words: diatomite, compound fruit beverage, chitosan, pectinase, Pomegranate, Hawthorn, clarification
