摘要: 研究了豆浆加热条件、凝固条件和GDL浓度对豆腐凝胶强度和保水性的影响。大豆蛋白的变性程度对豆腐凝胶网络结构有重要影响:生豆浆加热到95~100℃并保温5min左右是制取强度高、保水好的豆腐凝胶的基本条件:豆浆中的GDL浓度对豆腐凝胶保水性没有影响,但适度增加GDL浓度,可显著提高豆腐凝胶强度;提高凝固温度,可以缩短凝固时间,并可显著增加豆腐凝胶的强度。

关键词: 豆腐凝胶, 凝胶强度, 保水性

Abstract: The effects of heating conditions of raw soyamilk,GDL concentration in soyamilk and coagulating conditions on tofu-gel strength and water-holding capacity were investigated. Denaturation degree of protein had important effect on tofu-gel network formation.The optimum heating conditions of raw soymilk were 95~100℃ for about 5minutes for making tofu-gel of high strength.Water-holding capacity was independent of GDL concentration in soymilk,but th tofu-gel strength could be increased largely by increasing GDL concentration properly.With increasing coagulation temperature, coagulation time could be decreased and tofu-gel strength increased remarkably.

Key words: Tofu-gel Gel-strength Water-holding capacity
