Research Progress of Decolorization and Ion Exchange Resin Applied to the Refining of Functional Sugar
Functional sugar is a kind of high quality carbohydrate with various physiological functions,which has been gradually paid attention to because of its physiological effects such as reducing blood lipids,promoting the growth of beneficial intestinal bacteria and enhancing immunity.In the process of preparing functional sugar,impurities such as pigment and inorganic salt are easy to produce,which affect the quality of the product.Decolorization and ion exchange resin have been gradually applied to the purification of functional sugar due to the advantages of fast adsorption speed,easy operation and long service cycle.In this paper,the application of decolorization and ion exchange resins in functional sugars was reviewed,in order to provide theoretical support for the subsequent purification and industrial production of functional sugars.
