Is it okay to heat yogurt and drink it?

We usually drink some dairy products, the most common ones are milk and yogurt. Milk is relatively pure, and yogurt has a sour and sweet taste. Many people usually can't eat cold things, but yogurt is usually kept in the refrigerator. Then there is such a question, can yogurt be heated before drinking?

Many people believe that the most beneficial part of yogurt to the human body is "lactic acid bacteria", but lactic acid bacteria will all die under high temperatures, so the heated yogurt has almost no value. In fact, yogurt can be drunk warm. The reason why yogurt should not be heated is because people are worried about killing the most valuable lactic acid bacteria in yogurt. If steamed or heated, a large number of active lactic acid bacteria contained in it will be killed, the physical properties will change, separation and precipitation will occur, the taste and mouthfeel will disappear, and its nutritional value and health function will be reduced. If the yogurt is only heated, the lactic acid bacteria in the yogurt will not be killed. Instead, the activity of the lactic acid bacteria will be increased, and its unique health-care effects will be greater.

However, yogurt heating should be limited and conditional. Yogurt inoculation is carried out by immediately cooling the sterilized milk to around 45°C. When using a mixed fermentation agent of Lactobacillus bulgaricus and Streptococcus thermophilus, the temperature is maintained at 41°C to 42°C, the incubation time is 2.5 to 4.0 hours (2% to 4% inoculation amount), and the fermentation is terminated when a coagulation state is reached. The fermented coagulated yogurt should be immediately moved to a cold storage at 0℃~4℃ to quickly inhibit the growth of lactic acid bacteria to prevent continued fermentation and increase in acidity. Generally, the yogurt you buy is refrigerated and should not be consumed directly in winter.

If it is winter, the weather is relatively cold, or if you have a bad stomach and are prone to stomach acid, you should not eat too much spicy, raw, cold or irritating food. Yogurt can still be heated before drinking. It can be heated to about 45 degrees. In this way, the lactic acid bacteria in it will not be killed, and it also has certain nutrients.
