中文摘要: 为了研究甘蔗汁的保鲜工艺。利用单因素法考查了加热温度、加热时间和柠檬汁与甘蔗汁体积比对甘蔗汁保 鲜的影响,在此基础上利用 L9(34)正交试验考查了甘蔗的 3、6、9 d 的保鲜效果。结果表明适当的增加加热温度、延长加 热时间和增加柠檬与鲜甘蔗汁的体积比能够有效延长甘蔗汁的保鲜时间。甘蔗汁贮藏 6 d 的最优组合为 A3B3C2,即处理 温度为 140 ℃,处理时间为 45 min,柠檬汁与甘蔗汁体积比为 4 ∶ 40;因素的主次关系为:处理温度(A)、处理时间(B)、柠 檬汁与甘蔗汁体积比(C)。鲜甘蔗汁在加入柠檬汁与甘蔗汁体积比为 4 ∶ 40,120 ℃温度下加热 25 min 时,甘蔗汁可有效 保鲜 9 d。

Abstract:In order to preserve sugarcane juice, it was heated under different treatment(A) ,heat time(B)and the ratio of lemon juice (C). The vitamin C, soluble solid, total sugars content, pH were determined. The optimal process conditions was selected , namely when it was heated at 120 ℃ for 25 min, and the volume of lemon juice and sugarcane juice was 4 ∶ 40. The change of total sugars, vitamin C, pH value, soluble solids content were slowed and the browning of fruit juice was inhibited. On this condition, the sugarcane juice can be preserved for 9 days. This study may provide reference for research on preservation of sugarcane juice.
