Abstract

The invention discloses a preparation method of granular fermented dairy product allowing long-term normal temperature preservation. The method comprises the steps as follows: a fermentation agent isadded to milk undergoing centrifugal sterilization and pasteurization, and yogurt is prepared, stirred and sterilized; a granular product is sterilized by a tubular or scraper sterilization machine; the yogurt and the granular product are mixed, the mixture is uniformly mixed by a mixing valve group, a static or dynamic mixer and a horizontal mixing tank, uniform mixing and sterile filling are performed by a filling machine, and the granular fermented dairy product allowing long-term normal temperature preservation is obtained. The method is simple, and commercial sterilization of the whole production process is realized. Compared with the prior art, the product has prolonged shelf life and can be stored and transported in the normal temperature environment.

Description

technical field [0001] The invention relates to the technical field of yogurt preparation. More specifically, it relates to a method for preparing granular fermented milk products that can be stored at room temperature for a long time. Background technique [0002] As a food popular among consumers, yogurt has nutritional value not only from live bacteria, but also metabolites produced during the fermentation process have extremely high nutritional value. Even without live bacteria, combined yogurt with nutritious fruit, grains and other nutrient particles is still a high-level nutritional and health food. This kind of dairy products has received widespread attention in recent years and has grown rapidly. However, this kind of granular yogurt needs to be stored at low temperature and has a short shelf life. And the existing improvement of the storage temperature and shelf life of this granular yoghurt is also mainly by adjusting the formula, and the improvement effect is l...
