Acid machine principle

Yogurt is undoubtedly a favorite of many people. They always want to drink a cup of yogurt half an hour after every meal. In fact, from another perspective, this also reflects the principle of health preservation. Yogurt plays a great role in helping us moisten the intestines. Especially those with poor digestive function need to drink more, because yogurt can also help us digest. In addition, it is said that yogurt can also help lower blood pressure.

Since yogurt is so good, how much do you know about the principles of yogurt? Do you also know how yogurt is formed? Do you know why it becomes like this? Even if you don’t know anything, it doesn’t matter. We will answer these questions one by one for you. I believe that you will gain a lot after reading this article.

The principle of making yogurt is that lactic acid bacteria ferment and grow in milk. As for the principle of the yogurt machine, it is to provide the optimal temperature (42 degrees) for the growth of lactic acid bacteria, so one component heats and one component controls the temperature, that's all.

It should be noted that 42 degrees is the optimal growth temperature for lactic acid bacteria, at which they grow fastest. Of course, it can also grow under other temperature conditions. Therefore, yogurt will go bad even if it is kept in a refrigerator at 4 degrees for a long time. This is because under 4 degrees conditions, lactic acid bacteria will grow excessively over time.

If you use a thermos, it is possible to measure the temperature after a while and add hot water when the temperature is low, but it will be very troublesome. Even so, it can only guarantee fluctuations within 42 degrees, and the fermentation effect is not as good as using a yogurt machine.

However, drinking yogurt does not prevent you from gaining weight. Yogurt itself contains a certain amount of calories. If you eat more on top of your original diet, it will also cause weight gain. The best way is to choose yogurt labeled skimmed and low-calorie. Although their taste is not as rich and mellow as full-fat yogurt, they are low in calories and will not accumulate in the body quickly and cause weight gain.

Now you should understand the principle of yogurt fermentation. But everything that has a good side must have a bad side, but as long as we control it in moderation there should be no problem. Just like yogurt, drinking too much will cause diarrhea, but not drinking it will cause indigestion, so you must grasp the right degree when choosing.
