摘要: 本研究将保加利亚乳杆菌和嗜热乳链球菌按1:1比例作为菌种,按3%接种量接入到红薯、牛乳的混合原料中,37、39、42℃发酵,定时检测发酵过程中的pH值。实验结果表明:总酸一直呈稳定增长的趋势。

关键词: 红薯, 乳酸菌, pH

Abstract: The Lactobacillus bulgaricus and Streptococcus thermophillus (1:1) were used as starer(3%) for fermentation of blending of milk and sweet potato syrup at 37℃, 39℃ and 42℃. The pH changes were studied periodically. Results showed that the total acidity increased steadily.
