Abstract

The invention belongs to the technical field of yoghourt, and particularly relates to a preparation method of pure high-protein corn stirring type yoghourt. The preparation method comprises the following preparation steps: 1) selecting corn with average crude protein content of 20% or above; 2) adding water, performing pulping and filtering to obtain filtrate; 3) adding sugar, and performing homogenizing; 4) performing sterilizing and cooling to obtain a mixture; 5) inoculating a leavening agent into the mixture, and performing fermenting; 6) performing cooling on the yoghourt in sections after fermentation; 7) when the temperature of the yoghourt is 0-7 DEG C and the pH reaches 4.7 or below, performing stirring to enable the average particle diameter of the yoghourt gel to reach 0.01-0.4mm, and performing filling, and 8) placing the filled yoghourt in a refrigerator at 4-6 DEG C, and performing post-curing for 8 h or above. The yoghourt prepared by the method has relatively high protein content and strong corn flavor.

Description

technical field [0001] The invention relates to the technical field of yogurt, in particular to pure high-protein corn stirred yogurt and a preparation method thereof. Background technique [0002] Yogurt is a milk drink with a sweet and sour taste. It is a milk product that uses milk as a raw material. After pasteurization, beneficial bacteria (starter) are added to the milk, and after fermentation, it is cooled and filled. Most yogurt products on the market are solidified, stirred and fruity with various fruit juices and jams added. Corn is rich in nutrients. In addition to carbohydrates, protein, fat, and carotene, corn also contains nutrients such as riboflavin and vitamins. It is a good raw material choice for making yogurt. [0003] But existing corn yoghurt basically needs to be prepared with milk source as raw material, as the Chinese invention patent that application number is 200910213464. After mixing, homogenization, sterilization, cooling, inoculation, cultiva...
