摘要:

以东北大豆为原料,通过对全豆磨浆粒度、凝固剂、凝固条件对全豆腐乳白坯的凝胶强度、硬度、弹性影响的单因素和正交试验,较系统地研究加工条件对全豆腐乳白坯品质的影响。结果表明:全豆豆浆经胶体磨磨浆3次,石膏与卤水以5:5的比例为混合凝固剂,凝固最佳工艺参数为点浆温度80℃、凝固剂用量(以干豆质量计)3.0%、豆浆可溶性固形物含量12%。此时,可使制得的全豆腐乳白坯质量与传统腐乳白坯接近。

Abstract:

In this study, we systematically investigated the effects of soybean slurry particle size, coagulant type and amount and coagulation conditions on the gel strength, hardness and springiness of white whole-soybean sufu pehtze. The best particle size was obtained through grinding whole soybeans using a colloid mill for three times. A mixture of brine and gypsum at a ratio of 5:5 was the best coagulant. The optimal coagulation conditions were established as follows: heating temperature 80 ℃, coagulant dosage 3.0% (on a dry soybean weight basis), and soluble solid content in soybean slurry 12%. Under these conditions, the sufu pehtze obtained had similar quality as traditional sufu pehtze.

Key words: white whole-soybean sufu pehtze, process condition optimization, gel strength, hardness, springiness
