| titleOfInvention | Preparation method of high-purity galactooligosaccharide |
| abstract | The invention relates to a preparation method of high-purity galactooligosaccharide. After the mixed solution of galacto-oligosaccharides prepared by the biological enzyme method is subjected to ultrafiltration and decolorization process flows, a method of combining full-chamber bed ion exchange technology and sequential six-bed simulated moving bed chromatography is adopted to prepare a high-purity galacto-oligosaccharide product. The method for preparing high-purity galactooligosaccharide has good separation effect and improves the product quality. Compared with the traditional ion exchange technology, the full-chamber bed ion exchange technology has the advantages that the acid consumption is reduced by 47%, the alkali consumption is reduced by 45%, the water consumption can be saved by 48%, and the production cost is reduced. The chromatographic separation technology is improved, the sequential simulated moving bed adopts sodium type large-aperture cationic resin, monosaccharide and disaccharide components can be better separated, the content of galactooligosaccharide can be improved to more than 98 percent from the original 95 percent, and the requirements of customers on high-purity galactooligosaccharide products can be met. |
