There are many kinds of probiotics that can be used in human body. If it is used as family health care, it is recommended to add Bifidobacterium. Bifidobacterium is the most important probiotic in human intestine, which has many benefits to human body. There is no explanation here. It is recommended that the landlord read the encyclopedia of Bifidobacterium.
Bulgarian bacteria and lactic acid bacteria are needed to make yogurt, so if you make yogurt directly from pure milk, all three bacteria should be added.
It is suggested that it is more convenient to buy pure yogurt with good shelf life directly as the strain for making yogurt, and then add Bifidobacterium to make yogurt with pure milk.
Here's a recipe learned from books:
First of all, the containers, spoons and mixers for making yogurt are disinfected with hot water. Then use a spoon to take 150 mg pure yogurt sold in the store as a yogurt strain (try to buy new yogurt), put it into a container, add 850 g low-fat or fat-free milk, stir with a blender, and keep the temperature during the heat preservation period.
The temperature at this time is almost 40 degrees, and the holding time varies from person to person. Because the longer the holding time, the stronger the acidity. People who don't like sour food can keep yogurt warm for 6-7 hours, and people who like sour food can keep it warm for about 10 hour. Put it in the refrigerator and eat it after cooling.
In addition, remember to add Bifidobacterium before eating. The powder of Bifidobacterium sold in the market is used here. If Bifidobacterium is added in the process of homemade yogurt, it will affect the reproductive effect.
