Zinc-rich yogurt and preparation method thereof

Abstract

The invention discloses zinc-rich yogurt. The zinc-rich yogurt is prepared from the following raw materials in parts by weight: 15-45 parts of a fresh cow milk-fresh goat milk mixture, 1-10 parts of nuts, 0.001-0.05 part of a zinc enhancer, 5-15 parts of lean meat, 0.2-2 parts of yolk and 0.002-0.025 part of yeast powder, wherein the mass percentage of fresh goat milk in the fresh cow milk-fresh goat milk mixture is 1%-20%. The yogurt has a good zinc supplementing effect and is easy to absorb. The invention further provides a preparation method applicable to the industrial production of the zinc-rich yogurt. The preparation method comprises the following steps: (1) thoroughly cooking the lean meat and the yolk, baking and grinding the cooked lean meat and yolk, and mixing the lean meat and the yolk with the nuts; (2) mixing and homogenizing the mixture in the step (1) with the fresh cow milk or the fresh goat milk, carrying out sterilization, and adding prebiotics and the yeast powder; (3) inoculating 6%-9% of fermentation strains of Lactobacillus bulgaricus, Streptococcus thermophilus and bifidobacteria, and fermenting for 160h, wherein the fermentation parameters are as follows: the indoor temperature is 40-50 DEG C, and the humidity is 67%-70%; and (4) adding a proper amount of saccharose into the obtained yogurt for seasoning.

Description

technical field [0001] The invention relates to zinc-enriched yogurt and a preparation method thereof. Background technique [0002] Zinc is an essential trace element for the human body. It has outstanding contributions to human sexual function and reproductive cells. It is often dubbed "the spark of life" and "the element of harmony in marriage". But in life, wrong eating habits can easily lead to zinc deficiency. The reasons for zinc deficiency are as follows: 1. The main dietary food in daily life is mainly cereals, but the bioavailability of zinc in cereals is particularly low. Only 15-30%. At the same time, if children eat too much refined food, the content of zinc will be lost too much, which will more easily lead to zinc deficiency in the body. According to reports, eating habits cause zinc deficiency in 60% of Chinese children. 2. When the land is planted, a large amount of agricultural chemical fertilizers are used, which largely inhibits the production of zinc ...

AI Technical Summary

Problems solved by technology

2. When the land is planted, a large amount of agricultural chemical fertilizers are used, which largely inhibits the production of zinc in plants, resulting in the general lack of zinc in the grown grains

4. Excessive drinking and eating sugar will also lead to a large loss of zinc in the body

5. The problem of absorption rate: if the absorption of zinc is not good, it will cause indigestion and other diseases

At the same time, excessive intake of iron and calcium will also lead to increased loss of zinc.
