Abstract

The invention discloses a preparation method of high-purity plant source oligomerization galactose. The preparation method comprises the following steps of obtaining saccharide liquid by the utilization of water extraction or concentrating soybean waste water to use the soybean waste water as to-be-fermented saccharide liquid, consuming monosaccharide and disaccharide in the saccharide liquid by the adoption of a fermentation method, breaking and dissolving fructose bonds in the structure of raffinose-type functional oligosaccharide, and reducing the contents of protein, organic acid, and inorganic acid to the lowest level through precipitation, decoloration, ion exchange, film filtering and the like to obtain the high-purity plant source oligomerization galactose. The oligomerization galactose is composed of galactobiose, galactotriose, galactotetrose and galactopentaose and the content ratio of the oligomerization galactose in total sugar is improved to 70-95% from 5-10% which is before the fermentation.

Description

technical field [0001] The invention relates to a preparation method of plant-derived galacto-oligosaccharides, in particular to a preparation method of high-purity plant-derived galacto-oligosaccharides. Background technique [0002] Galactooligosaccharides are divided into α-galactooligosaccharides and β-galactooligosaccharides according to the different galactosidic linkage modes, and plant-derived galactooligosaccharides belong to α-galactooligosaccharides. [0003] In addition to having the same function of proliferating bifidobacteria as β-galacto-oligosaccharides, scholars at home and abroad have also studied other physiological functions of α-galacto-oligosaccharides. α-galactooligosaccharides can play an anti-adhesion effect on intestinal endotoxins (Paton, J.C. & Paton, A. W. (1998), Clin. Microbiol. Revs., U, 450-479; Carlsson, K.A. (1989), Ann . Reviews Biochem., 58, 309-350), inhibiting pathogenic bacteria such as Escherichia coli from adhering to the intestina...
