Two Bifidobacterium strains contained in two different fermented milks behave very differently when exposed to an in vitro simulated gastric environment. One strain survives very well during at least 90 min (greater than 10(7)/g), but the second strain studied is much less resistant. These in vitro results, with slight differences, were confirmed by an in vivo study in humans. The assessment of the gastric emptying rate of these products allows an estimation of the amount of Bifidobacterium that may pass into the small intestine.
两种不同发酵乳中所含的两株双歧杆菌菌株在体外模拟胃环境中表现出非常不同的行为。其中一株菌株在至少90分钟内存活良好（大于10⁷/g），但所研究的第二株菌株的耐受性要低得多。这些体外研究结果略有差异，并在人体的体内研究中得到了证实。对这些产品胃排空率的评估可以估算出可能进入小肠的双歧杆菌数量。
