| 摘 要： | 冷冻预处理有利于提高葡萄榨汁出汁率,但冷冻预处理对葡萄榨汁后汁液的品质影响目前尚不清晰。将葡萄果粒在-30℃条件下冷冻至中心温度-21℃,解冻后榨汁作为试验组,将果粒4℃条件贮藏后榨汁作为对照组,研究冷冻预处理对刺葡萄汁花色苷、色差、总糖、总酸等指标的影响。结果表明,葡萄汁在4℃条件下贮藏30天后,对照组与试验组中的花色苷含量、色差、总糖、总酸含量差异均不显著。说明冷冻预处理对刺葡萄汁品质不会产生不良影响。

| Abstract: | Freezing pretreatment was beneficial to improving the grape juice yield,but the effects on the quality of grape juice were uncertain.Grape fruits in experimental group were put into -30℃refrigirator to be frozen to central point temperature -2 1℃,and the effects of freezing pretreatment in the anthocyanins,color difference,total sugar and total acid of brier grape juice were studied.The result showes no significant differ-ence in the anthocyanins,color difference,total sugar and total acid of the control group and the experimental group after 30 days storage at 4℃.It illustrates that the effect of freezing pretreatment on the quality of brier grape juice was not affected. |
