The preparation method of yogurt is as follow:
1. Prepare milk, bacterial powder (Bifidobacterium) and yogurt machine liner. Iron the spoon, liner and lid with freshly boiled hot water in advance.
2. Take a bag of 1L milk powder, which will almost fill the whole liner.
3. Stir the milk in the inner container evenly with a spoon.
4. Cover the liner and put it into the yogurt machine. It takes about 10 hour to plug in the power, because the time required is different at different room temperatures. If the room temperature is too low, you can pour warm water of about 40 degrees in front of the yogurt machine and the inner container.
Because there are no additives, the taste and taste of yogurt made are not as good as those sold outside. You can give it to your baby with some fruits (such as bananas, blueberries, mangoes and cantaloupes). If adults eat it, it is suggested to add honey and condensed milk to the prepared yogurt, which tastes great and can completely replace the ready-made yogurt.
Extended data:
"Streptococcus thermophilus" and "Lactobacillus bulgaricus" will be added in the production of ordinary yogurt, but they are not varieties that can enter the intestinal tract for colonization, and have little effect on the regulation of the stomach.
Whether yogurt is pure or not depends on what raw materials are used to produce yogurt. There are two main raw materials for producing yogurt: one is milk powder and the other is fresh milk. Yogurt made of fresh milk is called "yogurt", and yogurt made of milk powder is called "reconstituted milk yogurt".
Restored milk is milk blended with milk powder. After two high-temperature treatments, a lot of nutrients were lost. But it doesn't mean that reconstituted milk yogurt is not good, but that non-reconstituted milk is better than reconstituted milk under the same milk source.
