Can yogurt be cooked

Yogurt cannot be boiled. If it is boiled, it will go bad. Therefore, it is recommended that you drink yogurt directly instead of boiling it. Heating yogurt will destroy the lactic acid bacteria in the yogurt, so that we can't promote gastrointestinal digestion when drinking yogurt, and the taste of the yogurt will also change. Now you can understand the benefits of drinking yogurt.

Can yogurt be heated?

cannot!

Yogurt cannot be heated directly and drunk. If it is steamed or boiled, a large number of active lactic acid bacteria it contains will be killed, and its physical properties will change, causing separation and precipitation. The taste and mouthfeel will disappear, and its nutritional value and health functions will be reduced.

Yogurt can be drunk warm

To drink it warm, slowly heat the yogurt with warm water at about 50℃. However, it is worth noting that if the temperature exceeds 50℃, it may kill the bacteria and affect the quality of the yogurt. Temperatures over 40 degrees Celsius will not kill these beneficial bacteria, and warming with insulated water is the most reasonable heating method.

The taste of yogurt changes when it is warmed

After being heated, the activity of lactic acid bacteria intensifies and more lactic acid is produced, but they themselves cannot adapt to the high temperature and slowly die, leaving sour yogurt. The lactic acid bacteria are gone, so drinking like this will not do any harm to the body, but it will also not bring any benefits to the body.

Yogurt will precipitate after heating

Yogurt is rich in protein. Due to the effects of physical and chemical factors, the spatial conformation of protein changes and the biological activity is lost. This process is called protein denaturation. The solubility of denatured proteins often decreases, the viscosity increases, the diffusion coefficient decreases, and precipitation occurs. Therefore, it is normal for precipitation to occur and there is no need to worry about deterioration. (Unless the yogurt being heated is already spoiled and expired.)

Yogurt becomes thinner when heated

Lactic acid bacteria need to convert sugars into lactic acid in an anaerobic environment, and the suitable temperature is generally between 26°C and 36°C. As mentioned above, the bacteria fermentation requires suitable temperature and anaerobic environment, so when you heat the yogurt, protein sugars are broken down into polypeptides under the action of lactic acid bacteria, and amino acids are broken down into smaller particles, so it feels thinner.

Tips for drinking yogurt

1. The best time to drink yogurt is 2 hours after a meal, because the pH value of gastric juice rises after a meal. This environment is very suitable for the growth of lactic acid bacteria, which can fully exert the nutrients of yogurt.

2. Don't drink yogurt on an empty stomach. The active lactic acid bacteria in yogurt can only grow when the pH value is above 4, and the pH value is below 2 when you are on an empty stomach, so the lactic acid bacteria will be killed by stomach acid and the nutritional value will be greatly reduced.

3. Do not heat yogurt before drinking. If the temperature is too high, the beneficial bacteria in the yogurt will lose their activity.

4. If you buy yogurt for a few days at a time, you should store it in the refrigerator. The shelf life of yogurt is generally only 7-14 days, so do not keep it for too long.
