What is heat-resistant probiotics?

Probiotics are quite sensitive to the external environment, especially temperature and humidity, which are the important factors affecting their survival. The optimal growth temperature for most probiotics is between 30 ~ 40℃. Once the temperature exceeds 45℃, the probiotics will begin to die in large number. This causes their storage and application to be considerably restricted. However, among the probiotics, there is a subgroup of bacteria ─ Spore-forming Probiotics, which have stronger heat tolerance than general probiotics. To against the environmental turbulence, spore-forming probiotics have evolved a special dormant state, called Endospore. The endospores have extremely low water content and are highly resistant to high temperatures, acids, alkalis, antibiotics and ultraviolet rays. Besides, the core of endospores includes important genetic factors for bacteria (DNA). When the external environment becomes more favorable, the endospore will reactivate itself to the vegetative state.

Recently, many studies have shown that spore-forming probiotics have multiple benefits to the human body. In addition to effectively improving the symptoms of irritable bowel syndrome and preventing leaky gut, spore-forming probiotics can also relieve allergic reactions and improve immunity. Therefore, the spore-forming probiotics are extensively applied to general foods, health foods and animal foods. Such facts make them become the new favorite of the modern food industry.
