As for whether soaking in milk powder also has the same effect, experts say that after the ingredients of milk powder are dried, they cannot maintain freshness, and there are fewer lactic acid bacteria, and the effect of skin care is not as strong as that of fresh milk.

However, it should be noted that if the expired milk has already clumped, do not use it, because lactic acid will not clump, and it is milk protein that will clump, which has no effect on exfoliation or moisturizing.

The traditional sense of the old yogurt mountain cavity, called coagulated yogurt, presents a solid state, it must use fresh milk as raw materials, semi-finished products are filled into predetermined packaging, sealed and implemented 72 hours of refrigeration fermentation, long production time, relatively short shelf life.

As consumers have higher and higher requirements for taste, people add a little more gelling agent or thickener to the basic comic shirt of ordinary yogurt, which becomes "old yogurt". Strictly speaking, the "old yogurt" products on the market should be called "yogurt jelly".

There are several main factors that affect the quality of yogurt:

1. Raw milk is mixed with water, and the dry matter is insufficient. When the water is 15%, the yogurt curd floats in the whey.

2. The coagulation ability of raw milk is reduced, and the yogurt curd is fragile or thin soup.

3. The production of yogurt from the milk of cows that have been injected with antibiotics will cause the yogurt to not coagulate and the emulsion to be sweet.

4. The workshop environment and equipment are polluted by bacteriophages.

5. The flavor and aroma of yogurt are insufficient due to improper selection of strains or single strains, unsuitable fermentation temperature, insufficient fermentation time, etc.

At present, the classic "pasteurization method" is applied to the processing of yogurt, which has the advantage that only part of the thermophilic bacteria and thermostable bacteria and spores remain in the sterilized milk, most of these bacteria are lactic acid bacteria, and lactic acid bacteria are not only harmless to people but beneficial to health. But because the products obtained in this way are not sterile, i.e. they still contain microorganisms, and after expiration, especially when stored in a warmer environment, it will lead to the breeding of harmful bacteria, and milk will be a breeding ground for them!

The fermented coagulated yogurt should be immediately moved to the cold storage of 0 4 to quickly inhibit the growth of lactic acid bacteria, so as not to increase the acidity caused by continued fermentation. Generally, the yogurt bought is refrigerated and should not be drunk directly in winter. You can put the yogurt in about 45 warm water and slowly warm it, shake it as you warm it, and when it feels mild, you can drink it.
