江蓠加工过程中成分变化对凝胶强度的影响

在确定最佳工艺条件的基础上，研究了江蓠藻及其琼胶中的蛋白质、矿物质在碱处理过程中及提胶过程中的变化趋势，井分析了蛋白质和主要矿物质成分与凝胶强度的关系。加工过程中江蓠藻中蛋白质和矿物质总的变化趋势是含量大幅度下降，而琼胶中的蛋白质、矿物质含量一般与原料江蓠中蛋白质、矿物质含量无关，而主要与加工精制工艺有关。江蓠原料中的矿物质，如钠、锌、钾、磷等对江蓠的含胶量及其琼胶凝胶强度有显著的影响。

EFFECT OF COMPONENT CHANGE ON GEL STRESS DURING THE PROCESS OF GRACILARIA

This paper discusses the changing tendency of protein and minerals in gracilaria and agar during the alkali treatment and gel extraction on the basis of the optimum conditions, and analyses the relations between protein, minerals and gel stress. During the process, the changing tendency of the protein and minerals in gracilaria is that the content decreases greatly, and the content of protein and minerals in agar has nothing to do with the content of protein and minerals in gracilaria, but mainly has something to do with the refining process. The minerals in gracilaria, such as sodium, zinc, potassium, phosphorous etc., have remarkable influences on the gel content of gracilaria and agar gel stress.
