[Method] Taking fresh yam as main materials, optimized wheat, skimmed milk and white sugar as auxiliary materials, the lactic acid bacteria developed into healthy drinks with unique flavor. The ratio of raw materials, the best conditions for hydrolysis of malt, lactic acid fermentation process conditions, such as product formulations were studied. [ Result ]The best conditions for the yam matt enzyme dosage was 21.0%, malt dosage 1.4%, reaction temperature 68℃, hydrolysis time 60 min; optimal fermentation process to increase milk production 2.4% , fermentation temperature 38 ℃, fermentation time 7. 0h, inoculums size 5.0%. [ Conclusion] The fresh yam tastes fresh, sour and sweet. The natural white ram is of high quality.展开更多
