Abstract

The invention provides a fermentation freezing solid dairy product and a preparation method thereof. The method comprises the steps of preparing fermentation substrate feed liquid, performing homogenization and sterilization and then performing cooling, inoculating fermented strains, and performing fermentation to obtain fermented milk; mixing the fermented milk with a postmixed material, and obtaining frozen yogurt mixed feed liquid; performing congelation and freezing on the frozen yogurt mixed feed liquid, and obtaining a fermented frozen solid dairy product; wherein the congelation is performed by utilizing a congelation machine through a continuous congelation process, the feeding and discharging speed is maintained to be 30-100% of the pump speed, the congelation machine is provided with an all sealed type stirring scaler, the refrigeration temperature is controlled to be -15 DEG C to -35 DEG C, and the discharging temperature is controlled to be -3 DEG C to -4.5 DEG C. The manufactured fermented frozen solid dairy product has good flavor and taste and a large number of survival bacteria.

Description

technical field [0001] The invention relates to a fermented frozen solid dairy product and a preparation method thereof, belonging to the field of food processing. Background technique [0002] Fermented frozen solid dairy products, commonly known as frozen yogurt (frozen yogurt), are a combination of the nutritional and health benefits and special flavor of yogurt and the cold feeling and delicate texture of ice cream. It has the characteristics of long shelf life and various eating methods. Frozen yogurt is divided into active frozen yogurt and sterilized frozen yogurt according to whether it contains active lactic acid bacteria. Among them, active frozen yogurt is very popular among consumers because it contains active beneficial bacteria. [0003] At present, the production process of active frozen yogurt usually adopts two production lines to prepare fermented milk and post-mix (mainly sugar solution), and then mix the two in proportion to make frozen yogurt mixture, a...
