Yogurt cannot be heated up and drunk. Due to the need to maintain the activity of this lactic acid bacteria, yogurt should be kept in a low temperature environment, usually around 2-8 degrees Celsius, and the preservation time is usually less than 1 month. If you find the yogurt too cold in winter, you can only put it in a bottle of water to keep it warm, not directly heated.

Yogurt has no nutritional value when heated.

After heating the yogurt, a large number of active lactic acid bacteria will be killed, and its physical properties will be changed, resulting in the separation of precipitation, the unique taste and texture of yogurt will disappear. The most valuable thing in yogurt is the lactic acid bacteria in yogurt, which can not only decompose lactose in milk to produce lactic acid and increase the acidity of the intestinal tract, but also inhibit the growth of putrefactive bacteria and weaken the role of putrefactive bacteria in the intestinal tract to produce toxins. If the yogurt is heated, the lactic acid bacteria in yogurt will be killed, and its nutritional value and health function will be reduced. Therefore, drinking yogurt can not be heated, summer drinking should be bought now drink, winter can be placed at room temperature for a certain period of time before drinking.

Drinking Yogurt Knowledge

1. Drinking yogurt is the best time to drink 2 hours after a meal, because after a meal, the PH value of the gastric juice rises, and this environment is very suitable for the growth of lactobacilli, which can make yogurt full of nutrients.

2. Don't drink yogurt on an empty stomach, yogurt active lactobacilli only PH value of more than 4 to grow, and fasting PH are below 2, so the lactobacilli will be killed by gastric acid, the nutritional value will be greatly reduced.

3. Do not drink yogurt heated, if the temperature is too high, the beneficial bacteria in yogurt will lose activity. If you buy a few days of yogurt at a time, should be placed in the refrigerator in the freezer to save, the shelf life of yogurt is generally only 7-14 days, do not put too long

Although the yogurt is very good to drink, but if you do not know some of its small knowledge, it will only be harmful!

Frequent drinkers of yogurt will notice the instructions on the package - yogurt needs to be stored at 2 ℃ ~ 6 ℃. Several supermarkets in Beijing found that not all yogurt is stored in the refrigerated cabinet, many yogurt is placed outside the refrigerated cabinet. Especially during the holiday season, some supermarkets even put single boxes of yogurt bundled together and wrapped in transparent packaging to sell outside the freezer.

There is no doubt that yogurt placed outside the freezer receives temperatures well above 6 degrees Celsius, so will the nutrition of yogurt be affected at temperatures higher than those of preserved yogurt?

Wang Huaibao, deputy director of the China Dairy Association, told reporters that the main ingredient of yogurt is active lactobacillus, which prevents protein fermentation and reduces intestinal gas production, thereby reducing bloating, indigestion and other symptoms. Under normal circumstances, the active lactobacilli in the environment of 0 ℃ ~ 4 ℃ survival period is static, but with the increase in ambient temperature lactobacilli will be rapid reproduction, rapid death, when the lactobacilli drink becomes an acidic dairy products without live bacteria, and its nutritional value will also be greatly reduced. Yogurt containing active lactic acid bacteria has a shorter shelf life, generally about two weeks, and must be stored at 2 ℃ to 6 ℃, otherwise it is easy to deteriorate.

So it seems, those placed in the supermarket outside the freezer yogurt already does not have 2 ℃ ~ 6 ℃ refrigerated conditions, its taste and nutritional value can not be guaranteed. Therefore, consumers in the purchase of yogurt should not only look at the shelf life, but also to look at the "temperature".

In addition, Wang, vice chairman of the Board of Directors to remind consumers, in drinking yogurt should pay attention to two points: First, avoid drinking yogurt on an empty stomach. Drinking yogurt on an empty stomach, health effects weakened, while drinking 2 hours after meals, health functions better. Secondly, yogurt avoid heating. Yogurt after heating, not only the unique flavor disappeared, and the beneficial bacteria were killed, the nutritional value is greatly reduced.

According to the Evening News, some people are worried that drinking cold yogurt in winter will cause gastrointestinal diseases, so they came up with a way to drink milk like heating. Experts believe that this makes yogurt lose its own nutrition, equal to drinking a glass of plain water. Because of the presence of lactic acid bacteria in yogurt is live bacteria, by heating or drinking with boiling water will be killed.
