The invention discloses a method and application for preparing unbranched straight-chain galactan with different molecular segments by enzymatic molecular machine technology. , α-arabinosidase and β-xylosidase, multi-enzyme combination constitutes an enzyme molecular machine technology system for preparing unbranched branched-chain mannan, removing arabinose+galactose in arabinogalactan Branched chains are then separated by centrifugation, flocculation and clarification, desalination and impurity removal by ion exchange technology, screening of molecular weight polymerization degree by membrane separation technology, and finally concentration and drying to prepare linear galactan with different molecular weights. Unbranched straight-chain galactan with different molecular weights not only has the characteristics of significantly enhancing immunity, significantly conditioning the gastrointestinal tract health functional food, but also can be used as the main component of the lead of the auxiliary anti-AD special medical food, and can also be used as an anti-inflammatory drug. The main components of the lead precursor substances of innovative drugs for AD disease. |
