yogurt can effectively improve the intestinal microbial environment, kill harmful pathogenic bacteria and prevent aging. Lactic acid bacteria fermentation in the intestine can prevent spoilage substances from decomposing protein and producing toxins, which can delay human aging, anticancer and anticancer effects. Yogurt contains calcium, potassium, zinc, magnesium, methionine, vitamins, enzymes and other bioactive substances. It also has many functions such as lowering blood pressure, preventing stroke and inhibiting cholesterol rise. Therefore, yogurt is loved by many people for its unique taste and health function. But winter is coming, the weather is getting cold, cold yogurt will always make the stomach uncomfortable, so can not yogurt heating?
can yoghurt be heated?
in fact, yogurt can be drunk after it is warm. It is a worry that yogurt should not be heated to kill the most valuable lactic acid bacteria in yogurt. If the cooking temperature is too high, a large number of active lactic acid bacteria will be killed, and their physical properties will change, resulting in separation and precipitation. The taste and taste will disappear, and their nutritional value and health care function will be reduced. If only the yogurt is heated, the lactic acid bacteria in the yogurt will not be killed, but will increase the activity of lactic acid bacteria, and its unique health care effect will be greater.
however, yogurt heating should be limited and conditions. Yogurt inoculation is carried out by cooling the sterilized milk to about 45 ℃. When the mixed starter of Lactobacillus bulgaricus and Streptococcus thermophilus was used, the temperature was kept at 41 ℃ ~ 42 ℃, the culture time was 2.5 ~ 4.0 hours (2% ~ 4% inoculum), and the fermentation was stopped when it reached the coagulation state. The fermented solidified yoghurt was immediately transferred to the cold storage at 0 ℃ – 4 ℃ to quickly inhibit the growth of lactic acid bacteria, so as to avoid the increase of acidity caused by continuous fermentation.
generally bought yogurt is refrigerated, it is not suitable to drink directly in winter. Yogurt can be put into 45 ℃ or so of warm water, slowly heating, with heating with shaking, etc. feel mild, you can drink.
