摘要:

以鲜牛乳为原料,采用添加嗜热链球菌改善嗜酸乳杆菌的发酵特性,对制作功能性微生态发酵乳进行研究。通过两种菌添加比例、发酵温度、接种量等参数的正交试验分析及发酵结果对产品进行模糊评判。结果表明:嗜酸乳杆菌和嗜热链球菌添加比例1:1、接种量9%、发酵温度41℃、发酵时间6h,可以得到凝块均匀、细腻、无气泡、气味清香并且具有弹性的微生态酸乳。发酵乳动物实验安全,并对实验所设计的致病性菌均有不同程度的抑制作用。

Abstract:

In this study, the fermentation characteristics of Lactobacillus acidophilus were improved by the addition of Str. thermophilus to develop a functional micrecological yogurt. The fermentation procedure was optimized by orthogonal array design, and the yogurt product produced was analyzed for edible safety, sensory quality and antibacterial activity as well as storability. A homogeneously clotted, exquisite, non-foam, nice-smelled, and resilient product was obtained by 6 h fermentation at 41 ℃ with 9% inoculation size of mixed Lactobacillus acidophilus and Str. thermophilus. The product had good edible safety for mice and displayed certain antimicrobial effects on some pathogenic bacteria.

Key words: Lactobacillus acidophilus, yogurt, microecology, fussy evaluation
