摘  要:
对豆腐柴叶豆腐形成的主要外界影响因子作了探讨,结果表明:豆腐柴叶制备的滤汁的鲜叶比水(w/v)为1∶8~1∶10,干叶粉比水(w/v)为1∶25~1∶30较为合适;添加0.02%~0.04%Mg2+或Ca2+能形成胶凝强度适中的叶豆腐,K+、Na+、Cl-、CO32-无促胶凝作用;在90℃加热30min不破坏被其叶滤汁胶凝特性;调整滤汁pH在4~5之间,能形成固定形态,质地均匀的叶豆腐;葡萄糖酸内酯有促胶凝作用,而琼脂仅起凝固作用,形成的叶豆腐弹性小,韧性差。

摘  要:
This article refer to the main environment gene,which influences Premna miophylla Tucz Leaf Doufu,s production.The effects indicate : it is applicable to produce the filter liquor of Premna miophylla Tucz foliage in the proportion of 1∶8-1∶10 of fresh foliage and water,or 1∶25-1∶30 of dry foliage powder and water: Adding 0.02%-0.04% of Mg~(2+) or Ca~(2+)could form the proper gum solidifying intensity of Leaf Doufu,but K~+,Na~+,Cl~-,CO_3~(2-) have no function of accelerated gum(solidifying;) the characteristic gum solidifying of the filter liquor can not be destroyed by heating for 30 minute in the 90℃: Maintaining the pH of filter liquor between 4 to 5.Leaf Doufu could be formed in solid and homogeneous: Glucose lactone has the function of accelerated gum solidifying,but agar only has the function of solidification.
