不渗透性

Two key technical parameters, for prevention ofdiscoloration and proper hardness, were determined after a lot of experiments. Firstly, in order to reduce the cost of pretreatment and improved its quality in storage,low priced additivs, such as high maltose syrup and maltose dextrine, were tested inosmotic treatment in production of dehydrated cabbage.

首先，针对切割甘蓝脱水制品实际生产中预处理方案成本较高、品质不稳定等问题，采用成本较低的高麦芽糖浆和麦芽糊精进行预处理，以甘蓝渗透后的水分含量和固形物增加率为试验指标，研究了它们在渗透过程中的脱水性和渗透性，并同葡萄糖和乳糖作了比较。
