采用 KOH溶液对沙菜进行高温稀碱法处理 ,通过正交实验方法得出了生产高凝胶性能卡拉胶的最佳碱处理工艺 ,所得卡拉胶的凝胶强度达到 80 0 g/cm2 ,产率超过 2 5%。该碱处理工艺具有工艺条件简单、生产周期短、环境污染少、碱液可循环利用等优点。 KOH solution was used to treat safflower with high temperature and dilute alkali method. The optimum caustic treatment technology for producing high gel properties carrageenan was obtained by orthogonal experiment. The gel strength of carrageenan reached 80 0 g / Rate more than 25%. The alkali treatment process has the advantages of simple process conditions, short production cycle, less environmental pollution, recyclable lye and the like.
