measure lactic acid bacteria reach the intestine alive the primary criterion

Lactobacillus choose to look at three things: strong activity, quantity, low temperature reservoir According to statistics, China's lactic acid bacteria beverage industry in 2011 than the previous year's sales increased by
nearly 54.8%. The same period, dairy products sales grew only 14.1%.
Lactic acid bacteria reach the intestine alive only to be effective, but from the mouth to the large intestine trek, not all of the bacteria can be passed through the ordeal, especially gastric acid and Zinc lactate.  Because the human body is very low PH value of gastric juice, which is about 2, which is to resist the alien harmful bacteria into the intestines, but it may also prevent some beneficial lactic acid bacteria into the intestine, so the acid of the "bacteria strong" as a measure of lactic acid bacteria the primary criterion for reaching the intestines alive. Is the number of viable cells arrive, can not
think big bottle containing viable on many bottles large capacity, high sugar content may also be just the key depends on the real number of viable cells can reach the intestine. Accordance with international standards is the number of viable cells per milliliter at least 10 million or more, and high-
quality active lactobacillus drinks, such as potassium lactate of viable cells can contain up to 100 million / ml, and experiments in artificial gastric juice proven to arrive alive intestinal tract, thus ensuring a sufficient amount of energy in the intestinal lactic acid bacteria play a useful role.
