Note: yogurt is not sour as possible
Yogurt is one of the favorite drinks of many people. However, yogurt is very acidic, some are sweet and sour, while others are sweet.
Too many people have such questions. Since the name is yogurt, is it so acidic, indicating that the nutrition is better?
Before answering this question, the first thing to do is to understand how milk is sour.
The lactic acid bacteria added to the milk are fermented to produce lactic acid and the like, and the milk becomes a sour yogurt.
Normally made yoghurt, because of the addition of sugar or sweetener, its sourness and sweetness are well matched and the taste is very good.
However, increasing the yoghurt placement time, the lactic acid bacteria will grow slowly, and the acidity of the yoghurt will increase slowly. However, in the low-temperature storage environment, the acidity of the basal yoghurt is acceptable to the human body, and the activity of the lactic acid bacteria is also better.
However, the acidity of yoghurt is limited. If the yoghurt is stored and the cold chain is removed from the process, if it is left in the outdoor environment, the lactic acid bacteria will rapidly multiply and the acidity of the yoghurt will increase and exceed the range.It will be very acidic, and the lactic acid bacteria activity will decrease, and the degree of degeneration of milk protein will increase, which is not conducive to human body absorption, and is not conducive to gastrointestinal health.
Therefore, yogurt is not as acid as possible.
When purchasing yogurt, be sure to choose the product placed in the freezer to ensure the freshness and safety of the product.
If you buy a promotional product that is close to the shelf life, you should not buy a large amount of cheap, avoid eating expired yogurt.
Since the yogurt is temporarily removed from the cold chain during shopping, it should be relocated or placed in the refrigerator as soon as possible after returning home, avoiding being placed indoors.
