以羊奶为原料，研究水苏糖、低聚木糖、低聚果糖、低聚乳果糖、低聚半乳糖、低聚异麦芽糖6种益生元对酸羊奶中乳酸菌活菌数的影响。结果表明，水苏糖对乳酸菌有增殖作用，其最佳用量为1 g/100 g羊奶；低聚果糖、低聚半乳糖和低聚异麦芽糖对乳酸菌也有增殖作用，低聚果糖最佳用量为1.6 g/100 g羊奶、低聚异麦芽糖最佳用量为2 g/100 g羊奶，其中低聚半乳糖的增菌效果最明显，最佳用量为1.2 g/100 g羊奶。在复合益生元研究中，发现低聚半乳糖和低聚异麦芽糖的比例为2∶1，添加量为3 g/100 g羊奶时，增菌效果较好；当低聚半乳糖和低聚异麦芽糖的比例为3∶1，添加量为2 g/100 g羊奶时，增菌效果较好。综合比较，确定益生元的最佳添加量为低聚半乳糖和低聚异麦芽糖比例为3∶1，其添加量为2 g/100 g羊奶时，酸羊奶中乳酸菌活菌数最高。

This paper studies the effects of 6 prebiotics on lactobacillus' count in goat yogurt, including stachyose, xylo oligosaccharide, fructo oligosaccharide, lactosucrose, oligo galactose and isomaltooligosaccharide. The results show that lupeose has a proliferation effect with the optimal dosage of 1 g/100 g; fructo-oligose, galactooligosaccharide and isomaltooligosacharide have the same effect with separate optimal dosage of 1.6 g/100 g, 1.2 g/100 g, 2 g/100 g. The study of compound probiotics shows better effects come from the proportion of 2∶1 (galactooligosaccharide and isomaltooligosacharide) with additive amount of 3 g/100 g. Proportion of galactooligosaccharide and isomaltooligosacharide 3∶1 has the same effect with addictive amount 2 g/100 g. After comprehensive comparison the highest viable count of lactobacillus in goat yogurt can be achieved with the addictive amount of 2 g/100 g and proportion of 3∶1 (galactooligosaccharide and isomaltooligosacharide) .
