| 摘 要： | 将益生菌L．casei Zhang以2．0×10^7cfu／g的接种量接种在马乳中进行发酵，测定其发酵特性及28d贮藏期间人工消化液的耐受性。结果表明，在发酵结束（pH4．5）时，活菌数较接种时增加了1．11个对数单位。在28d贮藏期间，发酵马乳样品pH降低了0．35个单位，滴定酸度增加了16°T，活菌数保持在10^8cfu／g以上。贮藏28d后，发酵马乳样品中L．casei Zhang在pH2．5和2．0人工胃液消化3h后，其存活率分别为100．6％和46．22％，又经人工肠液消化8h后，存活率分别降为74．83％和11．04％。L.casei Zhang保持良好的贮藏稳定性及较好的人工消化液耐受性，显示了其应用于发酵乳制品中良好的潜力。
