Abstract

The invention discloses no-additive fruit-grain yogurt and a preparation method thereof. The preparation method comprises the steps of (1) concentrating and cooling raw milk to obtain concentrated milk; (2) homogenizing and sterilizing the concentrated milk; (3) inoculating fermented strains into the concentrated milk, and fermenting at the temperature of 35-45 DEG C to obtain fermented milk; (4) overturning and cooling the fermented milk, and adding no-additive fruit grains on the production line to obtain the no-additive fruit-grain yogurt. The content of solid in the concentrated milk is 17%-25%, and the percent is based on mass; the no-additive fruit grains include fruit pulp or fruit grains and fruit pulp, and the fruit is from one or more of pineapple, blueberry, mango and red date. The no-additive fruit-grain yogurt provided by the invention has the advantages that the nutritional value is high, the state of tissue is fine and uniform, no whey is separated out, the flavor is unique and industrial production can be realized.

Description

technical field [0001] The invention relates to a yoghurt without adding fruit pieces and a preparation method thereof. Background technique [0002] Yogurt is fermented from fresh milk, which retains all the nutrients of fresh milk, and the lactic acid bacteria produced in the fermentation process can also provide a variety of vitamins necessary for the human body, which has a strong health care effect. Therefore, more and more consumers choose yogurt to replace milk. Manufacturers usually add food additives to yogurt products in order to industrialize yogurt, expand its production capacity, and maintain good texture and taste in logistics, transportation and marketing. [0003] For example, modified starch and gelatin are added to fruit fermented milk as thickeners and stabilizers, so that the fruit is suspended in the entire fermented milk system and remains stable for a long time. However, food additives are different from food nutrition fortifiers, and generally do no...
