采用过氧化氢氧化法制备水溶性壳寡糖,采用Q TRAP LC/MS/MS System测定壳寡糖的平均分子量,观察其对双歧杆菌的增殖作用,试验结果表明,分子量609水溶性壳寡糖在浓度为0.05%时,对于双歧杆菌具有明显的增殖作用。
Water-soluble chitooligosaccharides were prepared by hydrogen peroxide oxidation. The average molecular weight of chitooligosaccharides was determined by Q TRAP LC / MS / MS System. The proliferation of bifidobacteria was observed. The results showed that the molecular weight of 609 water- Sugar at a concentration of 0.05%, for Bifidobacterium obvious proliferation.
