采用豆粉冲调、均质、添加凝固剂和85 ℃水浴加热15 min的方式制作即食豆腐脑。研究了不同添加量的葡萄糖酸-δ-内酯(GDL)、氯化钙和氯化镁对制作的即食豆腐脑特性的影响。结果表明,GDL、氯化钙和氯化镁单一使用时,添加量分别在0.50%、0.30%和0.40%时豆腐脑产品凝胶效果较好。在对以上3种凝固剂进行不同比例复配,从质构特性和感官评价两方面确定了GDL、氯化钙、氯化镁的复配比例在10∶2∶3时开发的即食新产品相较于单一使用凝固剂和其他3种复配比例有显著优势(P<0.05)。 相似文献

甜玉米风味豆腐脑的研制 总被引:1,自引:0,他引:1
本文以大豆、甜玉米为主要原料,利用葡萄糖酸-δ-内酯作为凝固剂,研究了甜玉米风味豆腐脑的制作工艺.并采用正交优化试验方法,研究了豆浆浓度、甜玉米汁与白砂糖的用量比例以及葡萄糖酸-δ-内酯用量对甜玉米风味豆腐脑产品质量的影响。试验结果表明:当打浆时干大豆与水的比例为1:13,甜玉米汁用量为8%,白砂糖用量为7%,β-环状糊精用量为1.5%,葡萄糖酸-δ-内酯用量为0.25%.凝固温度为78℃,凝固时间为20min时,甜玉米风味豆腐脑产品的色泽呈淡黄色,具有良好的甜玉米风味和纯正的豆香味,并且豆腐脑的口感细腻、凝胶强度适中。 相似文献

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。 相似文献

BACKGROUND: The characteristic of whole soybean curd is that it includes the soybean residue that is discarded as waste in the manufacture of usual soybean curd (known as tofu). In this study the effect of dietary whole soybean curd on lipid profiles in rats was compared with that of usual soybean curd. Rats were fed for 4 weeks with diets differing only in the source of protein, namely casein, whole soybean curd or usual soybean curd. RESULTS: There were no significant differences in growth parameters due to diet differences. However, the two groups fed with curds had significantly lower levels of serum cholesterol and triglyceride than the group fed with casein, the greatest reduction in lipid profiles being observed in the group fed with whole soybean curd. The serum high‐density lipoprotein cholesterol/total cholesterol ratio was higher in rats fed with whole soybean curd. CONCLUSION: The results suggest the possibility that whole soybean curd may have more beneficial effects in controlling serum lipid profiles than usual soybean curd that is normally consumed.

The effects of fermented conditions on the production of total polyphenol from Lentinus edodes using soybean curd residue (SCR) were investigated in solid‐state cultures. Based on the results of single factor, inoculum size, moisture content and fermented time were optimised using central composite design in response surface methodology. As a result, the optimal fermented condition of total polyphenol production was determined as following: 12.13% inoculum size, 76.96% moisture content for 24 days incubation. Compared with unfermented SCR, the total polyphenol yield increased from 3.12 ± 0.02 to 22.93 ± 0.41 mg gallic acid equivalent per gram, and polysaccharides, protein and various amino acid of fermented SCR were increased significantly. Therefore, a nutritious functional food or food additives could be produced using fermented SCR. 相似文献
