Characterized with low quantity of heat,heat-resisting,anti-acid,anti-fermentation and other excellent physico-chemical properties,resistant dextrin could adjust the human intestinal flora,improve blood sugar and fat metabolism,reduce serum cholesterol and promote mineral absorption,which was widely used in food industry.Separation and purification was an important process to prepare high-purity resistant dextrin.The method and principles of microbial fermentation,nano filtration, ion-exchange chromatography,simulated moving bed and enzymatic purification were introduced,which could provide theoretical guidanceforthepreparationofhighpurityresistantdextrin.
