摘要
利用干法工艺制备全豆豆腐,在单因素实验基础上,选取葡萄糖酸-δ-内酯(GDL)、氯化镁(MgCl_2)和谷氨酰胺转氨酶(TG酶)添加量作为影响因素,以全豆豆腐凝胶强度和感官评分作为指标,进行Box-Behnken实验,建立二次多项式回归模型,用于全豆豆腐最佳凝固剂配方的优化。结果表明,GDL添加量对全豆豆腐凝胶强度的影响最大,TG酶添加量的影响最小;而感官评分二次多项式回归模型不显著。干法工艺制备全豆豆腐的凝固剂最优配方为:GDL添加量0.5%,MgCl_2添加量0.07%,TG酶添加量0.02%。在该条件下所制得的全豆豆腐凝胶强度为185.956 g;微观结构表现为致密、均匀和相互交联的凝胶网状结构。
This research was conducted to investigate the optimal coagulant formula for dry -processed whole soybean curd based on response surface methodology. The addition amount of glucose （GDL） , magnesium chloride （ MgCl2 ） and glutamine transaminase （TG） were choosen as the influencing factors, the gel strength and sensory evaluation were used as the indicator for a Box - Behnken experimental design on the basis of single - factor experiment. Results showed that the addition of GDL had the most significant effect on the gel strength of whole soybean curd, while the addition of TG had the minimal effect. However, the quadratic polynomial regression model of sensory evaluation was not significant. The optimal coagulant formulation for making dry - processed whole soybean curd were ： 0.5% GDL,0.07% MgCl2,and 0.02% TG. Under these conditions,the gel strength of whole soybean curd was 185. 956 g. Moreover, a compacted and uniformed net structure was formed at this optimal condition through the exam- ination of scanning electronic microscopy.
