Is yoghurt more acid better? Before you answer this question, you must first understand how milk turns sour.
Lactobacillus added to milk fermentation to produce lactic acid and other substances, milk will become sour yogurt. Normal factory yogurt, due to the addition of sugar or sweetener, its sweet and sour appropriate, taste very good. However, with the extension of the storage time of yogurt, lactobacillus will grow slowly and the acidity of yogurt will also increase slowly. However, in the low-temperature storage environment, the acidity of yogurt within the shelf life can be accepted by the human body, and the activity of lactobacillus remains good. But there is a limit to yogurt acidity, if the yogurt out of the cold chain during the process of storage, logistics, such as suspended at room temperature or outdoor environment, lactic acid bacteria can proliferate and cause of yogurt acidity increases, and out of acceptable range, such as yogurt taste will be very acid, and lactic acid bacteria vitality, milk, protein denaturation degree increase is bad for the body to absorb, also go against health of intestines and stomach. Therefore, the more sour the better.
When buying yogurt, be sure to choose the product placed in the cryogenic refrigerator, so as to ensure the freshness and safety of the product. If you buy promotional products close to the expiration date, don’t be tempted to buy in bulk and avoid eating expired yogurt. Since it is inevitable that yogurt will break out of the cold chain for a short time during the shopping trip, it should be drunk or put into the refrigerator as soon as possible after going home to avoid being left at room temperature for a long time.
While milk is also high in calcium, the lactic acid found in yogurt combines with calcium to promote calcium absorption. Generally speaking, it is best to drink yogurt between 30 minutes and 2 hours after a meal. However, traditional Chinese medicine suggests that if you want to give full play to the biggest effect of calcium supplement, yogurt should be drunk at night.
The reason:
1.12 PM to early morning is the lowest body blood calcium content, conducive to the absorption of calcium in food.
- During the period from 12 p.m. to midnight, there are fewer factors affecting calcium absorption in the body.
