Abstract

The invention belongs to the field of fermented milk products, and particularly discloses a raw material composition of inflatable fermented milk. The raw material composition comprises, in weight percentage, 40.492%-79.493% of raw milk, 20%-50% of cream, 0%-7% of sugar, 0%-1% of concentrated milk protein, 0.5%-1.5% of thickening agents and 0.007%-0.008% of leavening agents. Parts of raw materials are fermented, the fermented raw materials and a composition of the cream and the thickening agents are mixed, and mixture is inflated to form the inflatable fermented milk. Air holes of the obtained inflatable fermented milk are uniform and durable, and the inflatable fermented milk is exquisite in taste.

Description

technical field [0001] The invention belongs to the field of fermented milk products, and in particular relates to aerated fermented milk and a preparation method of the fermented milk. Background technique [0002] At present, the fermented milk on the market is the same ordinary fermented milk, which is nothing more than two types: solidified type and stirred type. One has a blocky taste and the other has a fluid taste. For a long time, consumers have believed that fermented milk has only these two tastes, and many of the products are different because of different raw materials, different fermentation strains, different flavors and so on. In order to break the fixed perception of consumers and bring different taste enjoyment, the present invention utilizes post-gassing technology to make fermented milk have a mouthfeel similar to mousse, giving people a strong sense of freshness and unique feeling. [0003] The difficulty of aerated fermented milk is that it is difficult...
