The invention discloses a coagulated cheese flavor fermented milk. The coagulated cheese flavor fermented milk is prepared from, by weight, 80-90 parts of raw milk, 0.005 part of fermented culture, 0.5-2.0 parts of whey protein powder, 0.1-1.0 part of tremella polysaccharide, 5-10 parts of white granulated sugar, 0.5-3 parts of cheese powder and 0.01-0.1 part of edible salt. The preparing method comprises the following steps of 1, preparing materials, wherein partial liquid milk is taken, the temperature is raised to 45-50 DEG C, dry mixing is conducted on the whey protein powder, tremella polysaccharide and partial white granulated sugar, the mixture is put into the partial liquid milk after the temperature is raised, then the remaining white granulated sugar, cheese powder and the like are added, after even mixing is conducted, the liquid milk is used for maintaining constant volume, and the temperature is reduced to 20 DEG C or below; 2, sterilizing the prepared material liquid; 3, reducing the temperature of the fermentation raw materials to 10 DEG C or below, and inoculating the fermented culture; 4, after the inoculation completes, conducting temperature raising, filling and fermentation, and after the fermentation completes, transferring the fermented milk to a quick cooling room. The coagulated cheese flavor fermented milk is finer in structure, smoother in mouthfeel, purer in cheese flavor, rich in cheese fragrance and good in water retention.
