生物活性物质-低聚半乳糖

Biologically Active Substance-Galactooligosaccharide

介绍了生物活性物质－低聚半乳糖的性质、种类及化学结构，综述了它在促进人体有益菌群、抑制有害菌群的生长、减少肠内腐败物质、促进钙吸收、改善血清脂质等方面的生理功能。从游离酶、固定化酶和完整细胞等角度，详细介绍了低聚半乳糖的制备技术及其生产现状与前景。

The properties, types and chemical structures of galactooligosaccharide are presented. Its physiological functions,such as promoting the growth of beneficial bacteria,inhibiting detrimental bacteria,decreasing the putrefactive substances in intestine,promoting absorption of calcium and improving the lipid components in serum, have been reviewed. The preparation techniques for galacto-oligosaccharide with free enzyme, immobilized enzyme and whole cell as biocatalysts are introduced in detail. Its current research situation and prospects are also covered briefly.
