沙菜卡拉胶生产中碱处理对藻体的影响及工艺条件最优化研究

Effects on the Algae Tissue of Alkali Pretreatmentand Its Optimized Technique

以沙菜为原料，从其微观结构出发，观测碱处理过程中藻体细胞壁的变化情况，来研究不同碱处理试剂的作用机理，从而挑选适合的碱试剂。进一步以碱浓度、固液比、处理温度和时间为因素，采用均匀实验设计，研究沙菜生产卡拉胶的碱处理最佳工艺条件。

： The changes of cell wall were investigated in order to find the mechanism of different alkali agents and to choose the proper one during the alkali pretreatment of red algae Hypnea to extract carrageenan. And the optimized technique of producing carrageenan was also studied in this paper.
