摘要:

利用微生物发酵法脱除蚕蛹蛋白的臭味。结果表明:活性干酵母和瑞士乳杆菌发酵均可有效去除蚕蛹蛋白的臭味。活性干酵母发酵脱臭工艺条件为:从节省原料考虑,活性干酵母用量为0.3%,不加葡萄糖和其他营养物质, 37℃发酵80min 可完全除臭;从节省时间考虑,活性干酵母用量为0.3%、葡萄糖用量为2%,37℃下发酵28~35min 可完全除臭。瑞士乳杆菌发酵脱臭工艺条件为:活菌数为108CFU/ml 的瑞士乳杆菌液用量为2%、MRS 培养基用量为10%, 37℃下发酵7h 可完全除臭。

Abstract:

The silkworm pupae protein was prepared by sequential extraction and deodorized by microbe fermentation. The results showed that fermentation of silkworm pupae protein by yeast and Lactobacillus helveticus could effectively remove the bad odor of silkworm pupae protein. Deodorization process of yeast fermentation conditions were as follows: 0.3% of inoculated yeast at 37 ℃ for 80 min so as to save raw materials and 0.3% inoculated yeast in addition of 2% glucose at 37 ℃ fermenting for 28~35 min to save time. Deodorization process of Lactobacillus helveticus fermentation conditions were as follows: 2% of inoculated Lactobacillus helveticus, 10 % usage of MRS medium, 37 ℃and 7 h of fermentation.

Key words: yeast, Lactobacillus helveticus, fermentation, silkworm pupa protein, deodorization
