In general, the suitable growth temperature of lactic acid bacteria is between 30℃ and 40℃. When it reaches this temperature, lactic acid bacteria will grow, multiply and release a lot of lactic acid. When the temperature exceeds 40℃, the growth rate of lactic acid bacteria drops sharply and even stops growing.
Therefore, if food or drink containing lactic acid bacteria is heated to a high temperature, lactic acid bacteria will lose their activity. For example, if you heat yogurt or yogurt drinks, lactic acid bacteria will die when the temperature exceeds 40℃, so there will be no active lactic acid bacteria after drinking.
In short, if you want to get the benefits of lactic acid bacteria, you'd better not heat food or drink containing lactic acid bacteria, but choose to eat it directly or add other cold ingredients, such as adding lactic acid bacteria yogurt sauce to salads.
Can active lactic acid bacteria drink be heated? Active lactic acid bacteria drink is a kind of drink containing active lactic acid bacteria, which is often used to adjust the balance of intestinal flora and improve gastrointestinal health. So, can this drink be heated? The answer is that it is not recommended to heat active lactic acid bacteria drinks.
Why? Because the lactic acid bacteria in the active lactic acid bacteria drink is a kind of organism, it is easy to die after heating. For example, if the active lactic acid bacteria drink is heated above 70℃, the lactic acid bacteria will lose their activity.
Moreover, if you drink active lactic acid bacteria drinks after heating, it is easy to cause gastrointestinal discomfort. Because the activity of lactic acid bacteria is destroyed after heating, it can't grow and reproduce in the intestine, so it can't adjust the balance of intestinal flora, but it increases the burden on the stomach.
Therefore, if you want to drink active lactic acid bacteria, you'd better drink it cold or carry it with you at room temperature. If heating is necessary, it is best not to exceed 40℃ to avoid affecting the benefits of drinks.
In short, although lactic acid bacteria and active lactic acid bacteria drinks are very beneficial to human body, heating is not recommended. If you want to get the benefits of lactic acid bacteria after heating, you can add lactic acid bacteria products, such as yogurt, sauerkraut, pickled radish, etc., which can increase the nutritional value of food and keep the lactic acid bacteria from being lost.
