摘要: 以米皮糠为主要原料,采用正交试验方法,研究利用乳酸菌发酵米皮汁制成凝乳的最佳生产工艺。实验结果表明,最佳的工艺参数为:(1)最佳的米皮糠水解条件是料水比(米皮糠/水)1:5,蛋白酶的添加量0.25%,糖化酶的添加量0.05%,酶作用时间120min(其中蛋白酶作用时间45min);(2)最佳的米皮汁乳酸发酵条件是料水比(米皮汁/鲜奶)8:2,乳酸菌接种量3.0%,发酵温度41℃。

Abstract: The trial with the main substrate of rice polishings to produce gelated yoghurt was conducted by orthogonal design method of L9(34) to study its zymolytic technology. The results showed that: (1) the optimum parameter of hydrolyzation with enzyme in rice polishings is rice polishings/water 1:5, protease 0.25%, added saccharifying enzyme 0.05%, added with 120min. (2) the optimum zymolytic craft parameters from liquor of rice polishings were liquor of rice polishing/fresh milk 8:2, inoculation size 3.0%, zymolytic temperature 41 ℃.
