摘要
益生元是一种理想的人体膳食补充剂,可促进益生菌的生长代谢。本试验从活菌数、产酸能力、胞外多糖产量和双乙酰产量4个方面,研究了多种益生元,如低聚果糖、低聚半乳糖、低聚异麦芽糖、低聚木糖、聚葡萄糖、抗性糊精和菊粉对复合益生菌(干酪乳杆菌、鼠李糖乳杆菌)发酵代谢的影响。结果表明,低聚木糖对活菌数和产酸能力具有明显提升作用;抗性糊精可提高益生菌胞外多糖的产量,并且优于其他益生元;低聚果糖对促进双乙酰的生成具有明显优势。
Prebiotics are ideal human dietary supplements that can promote the growth and metabolism of probiotics.In this experiment,a variety of prebiotics,such as fructooligosaccharides,galacto-oligosaccharides,isomaltose,xylo-oligosaccharides,Effects of polydextrose,resistant dextrin and inulin on fermentation metabolism of compound probiotics (Lactobacillus casei,Lactobacillus rhamnosus).The results showed that xylo-oligosaccharides can significantly improve the number of viable bacteria and acid production capacity;resistant dextrin can increase the production of probiotic exopolysaccharides,and is better than other prebiotics;fructo-oligosaccharides can promote the production of diacetyl.has obvious advantages.
