摘要
为探讨热处理对红枣汁非酶褐变的影响,将红枣汁在50-100℃下进行热处理,测定红枣汁的褐变度,以及5-羟甲基糠醛(5-HMF)、还原糖、总糖和VC指标的变化。结果表明,随着热处理温度升高,时间延长,红枣汁的褐变度和5-HMF含量逐渐增加,还原糖、总糖、VC含量逐渐减少。
To explore the effect of thermal treatment on Non-enzymatic browning of Chinese jujube Juice,the changes in browning degrees,5-HMF,reducing sugar,total sugar and VC of Chinese jujube juice are measured during thermal treatment at 50~100 ℃.The results show that reducing sugar,total sugar and VC gradually decrease with temperature increment,time extension and browning degrees of Chinese jujube and 5-HMF content increment.
