[Method] With adoption of preliminary experiments and single factor experiment, we measured production pH, and in combination with sensory analysis, we managed to evaluate the fermentation agents, addition method, and addition proportion formula. [Conclusion] At total inoculation of 1×107 cfu/g, and with processing method of simultaneous addition, the optimal addition proportion is L:C:Y =1:2:1.展开更多
