Abstract

The invention belongs to the field of dairy products, and particularly discloses a preparation method of fermented milk. The method comprises the following steps of (a) preheating raw material milk, mixing with barley leaf powder, whey protein powder and a sweetening agent and carrying out homogenizing and sterilizing to obtain a mixed feed liquid; and (b) adding a leavening agent to the mixed feed liquid obtained in the step (a) and carrying out fermentation to obtain the fermented milk. The leavening agent is selected from one or more of lactobacillus acidophilus, lactobacillus rhamnosus and lactobacillus casei. According to the fermented milk prepared by the method, the intestinal health can be significantly promoted, development of the function of the fermented milk for regulating intestinal flora is facilitated, the market blank is filled, and furthermore, the fermented milk is high in stability and has excellent taste and flavor.

Description

technical field [0001] The invention belongs to the field of dairy products, and in particular relates to a method for preparing fermented milk.
