冷冻预处理对刺葡萄榨汁品质的影响
Effects of Brier Grape Freezing Pretreatment on the Juicing Quality
摘要
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.关键词
