Is yogurt made by yogurt machine healthy-harmful bacteria pollution
Yogurt is milk fermented by lactic acid bacteria, which belongs to fermented milk. The national standard allows the use of additives in fermented milk, which is the need of production technology. The limited and reasonable use of additives will not cause harm to human health. So don't worry too much about the problem that yogurt contains additives. Homemade yogurt can be made without additives. However, this does not mean that homemade yogurt will be safer. Because homemade yogurt needs fermentation, and fermentation needs the participation of microorganisms. Because there are a lot of bacteria in the environment, raw milk and fermentation utensils must be sterilized before fermentation. However, it is difficult to ensure strict sterilization conditions for homemade yogurt in ordinary family environment.
Is yogurt made by yogurt machine healthy? It tastes bad.
Friends who have made yogurt should know that their own yogurt tastes worse than those bought outside. This is because homemade yogurt needs to be fermented at 42℃ ~ 45℃, which is the most suitable growth temperature for mixing Lactobacillus bulgaricus and Streptococcus thermophilus. However, ordinary homemade yogurt is difficult to guarantee such conditions, and it is easily affected by the weather, unevenly heated, and easily over-fermented or under-fermented, which eventually leads to poor taste of homemade yogurt.
Is the yogurt made by yogurt machine healthy-it can't be mixed at will.
Yogurt goes well with many foods, especially breakfast with bread and snacks. It is dry and thin, delicious and nutritious. But don't eat it with high-fat processed meat such as sausages and bacon. Because nitrate, that is, nitrous acid, is added to processed meat, it will form nitrosamines with amines in yogurt, which is a carcinogen. If it is eaten with pickled food, it is best to eat it with fresh fruit, which can prevent the formation of carcinogenic nitrosamines, because vitamin C in fruit will preferentially react with sodium nitrite in pickled products. Yogurt is very suitable for eating with starchy foods, such as rice, noodles, steamed bread, steamed bread, bread and so on.
Steps of making yogurt by yogurt machine:
1, take the frozen yogurt starter out of the refrigerator;

5. Cover the container and put it into the yogurt machine;
6. When making in winter, you can add warm water to your body;
7. Cover the upper cover of the yogurt machine;
8. Plug in the plug and the yogurt machine starts to work; The microcomputer yogurt machine needs to set the fermentation time (see the instructions for details);
9. When pure yogurt is used as the fermentation source, the fermentation time is 6-8 hours; When yogurt starter is used as fermentation source, the fermentation time is 8- 12 hours; The fermentation time will be affected by the ambient temperature and the initial temperature of raw materials, so it is necessary to extend the time appropriately when the ambient temperature is low or when it is made with refrigerated milk. But the longest time is not more than 14 hour. (When pure yogurt is used as fermentation source, the longest time shall not exceed 10 hour)
10, the fermented yogurt condenses into "tofu flower" and can be eaten at about 40℃. In summer, put in the refrigerator, the yogurt has pure fragrance and excellent taste;
1 1. Yogurt can be flavored with fruit juice, fructose, honey, etc. Eat according to your own taste. The yogurt that has not been finished needs to be refrigerated at 4℃.

Select materials
According to professionals, the strength of acidic substances does decompose metals and ooze harmful substances, which is related to the actual situation of the solution! When all these are risky, only food-grade PP materials, glass, ceramics and other containers for yogurt will be the most suitable!
PP material, specially used for baby bottles, is a baby food-grade material.
The PP bottle is made of PP (polypropylene), which is internationally recognized as a safe material for making food containers. It does not contain the carcinogen bisphenol A. Professionals say that it is also stable in hydrochloric acid at 100℃. Acid and corrosion resistance.
