摘  要:
[Objective] To develop green tea yogurt with nutrition and health function. [Method] With the whole milk power and superfine green tea powder as the raw material,Streptococcus thermophilus and Lactobacillus bulgaricus as the lactic acid bacteria starter to produce the fermented green tea yogurt. Singer factor and orthogonal array design methods were used to investigate the effects of key technological parameters. [Result] Under the optimal conditions of green tea powder 0. 3%,sucrose 9%,inoculation amount 5%,fermentation temperature 42℃,fermentation time 4 h,the prepared yoghurt showed a shelf life for 5 d at 4 ℃. [Conclusion] The prepared yoghurt showed an uniform color,pale green,delicate tissue,slightly green tea fragrance,sweet and sour moderate.
