【摘要】 <正> 为了扩大制造琼胶的原料来源,弥补石花菜的不足,早在三十年代就有人开始研究利用江蓠来制造琼胶。研究的主要问题是如何提高江蓠琼胶的凝胶强度。1936年柳川最早发现用碱加热处理能提高江蓠琼胶的凝胶强度。其后陆续出现了不同的碱处理法。归纳起来可分为四类:一是低浓度碱热处理法;二是高浓度碱冷处理法;三是高浓度碱中溫处理法;四是中浓度碱热处理法。这些方更多还原

【Abstract】 Four alkaline treatment methods (high concentration alkali cold treatment, high concentration alkali warm treatment, medium concentration alkali hot treatment and low concentration alkali hot treatment) have been studied. Their effects on the gel strength and yield of agars from four species of Gracilaria were compared. The results show that the high concentration alkali cold treatment method is generally the best one of the four methods studied.更多还原
