If you buy untreated milk to boil, and then naturally cooled about 40 degrees;

If you buy directly drink the autoclaved milk can be heated only to about 40 degrees.

The most direct way to determine the temperature is to stick a clean finger into the milk, and if it doesn't burn your hand, it's warm.

2. Pour the purchased yogurt into the warm milk, stir well with clean chopsticks, cover the lid, and wrap the whole container with a towel.

The ratio of yogurt to fresh milk: 1 liter of fresh milk to 125 grams of yogurt. (125 grams is usually a small package of a small box)

Yogurt production

1. porcelain cup (with lid), spoon in a rice cooker with water boiled 10 minutes to sterilize

2. cups out of the pouring milk (7 minutes full, milk, if it is a new opening, the milk itself has been sterilized very well, you can not boil sterilized), will be put into the microwave oven to microwave the milk to the wall of the cup is not hot as the degree of the hand mold.

If the milk comes in a plastic bag, it's best to boil it and let it cool until it's not too hot to touch before doing the next step.

4. Disconnect the rice cooker, pour out the hot water in the cooker, put the porcelain cups into the rice cooker, cover the rice cooker with the lid, and cover the top with a clean towel or other heat-retaining item, and use the residual heat in the cooker for fermentation.

After 8-10 hours, the low-sugar yogurt is ready. If you make it at night, you'll have delicious yogurt the next morning.

Successful yogurt is semi-solidified, the surface is white and smooth, there is no whey (yellowish transparent liquid) precipitation, smells milky, if you like sweet, you can add sugar before eating. You can't put sugar before fermentation.

Homemade yogurt can not be sealed, so the storage time is also shorter than the time sold in the market, in the refrigerator can only be stored for 2-3 days.

Plain yogurt ...... .............................. ...125ml

Tools:

rice cooker, porcelain cup with lid, spoon, microwave oven (you can also use other methods to heat the milk, but with the microwave oven is not only faster, but also a good grasp of the heating temperature)

Practice:

1. Put the porcelain cup (with lid), spoon in the rice cooker with water and boil for 10 minutes. Sterilization.

2. Take out the cup and pour the milk (7 minutes full, if the milk is newly opened, itself has been sterilized very well, you can not boil sterilization), the milk into the microwave oven to microwave heating, in order to touch the walls of the cup is not hot to the degree.

Note:

1. The strain of yogurt used can not be used to add fruit ingredients, not to mention fruit-flavored yogurt.

2. Milk heating temperature, such as too high, will kill the lactic acid bacteria in the yogurt caused by the fermentation failure, such as the temperature is too low and will cause slow fermentation, in order to touch the degree of not hot.

3. Do not use the rice cooker insulation gear fermentation, because the insulation temperature is too high, insulation fermentation, the rice cooker must be powered off. If you make yogurt in winter, you can put the porcelain cup on the heater to ferment.

4. Fermentation container with a lid porcelain cup is best, hard plastic cups can also be, but if the quality of the cup is not, heating and sterilization is easy to deformation. The lid is very important, lactobacilli are anaerobic bacteria, anaerobic environment is more conducive to fermentation.

5. It is best not to use disinfectant to sterilize containers, because if you don't rinse well, it will kill the lactobacilli and make the fermentation fail. Heat sterilization is the safest method.

6. Anti-milk (containing antibiotics) or reduced milk (milk powder reduced to milk) are not suitable for making yogurt ingredients.
