AI Technical Summary

Technical Problem

The existing enzyme methods have high cost of producing oligolacose, large loss of enzyme activity, low purity of products, and many impurities contained in them. The commonly used decolorizer activated carbon will lead to a decrease in product content, resulting in slow progress in industrial production.

Method used

The ion exchange resin was pretreated and polyethyleneimine modified, supported by β-fructosidase, combined with ultrafiltration and nanofiltration membrane separation technology, synthesis and purification of lactulose oligosaccharose.

Benefits of technology

It improves the loading performance of the resin to enzymes and the activity of the enzyme, reduces by-products, shortens the synthesis reaction time, improves the purity and raw material utilization rate of lactulose oligosaccharides, reduces the subsequent purification cost, and is suitable for large-scale industrial applications.

Abstract

The invention discloses a production process and application of lactosucrose and relates to the technical field of lactosucrose preparation. According to the method, ion exchange resin is modified through polyethyleneimine, then beta-fructofuranosidase is loaded, then a lactosucrose synthesis reaction is conducted, polyethyleneimine contains a polar group amino and a hydrophobic group vinyl and has excellent adhesiveness and adsorbability, the specific surface area of the resin is greatly increased, the contact area of the resin and enzyme is increased, and the adsorption capacity of the resin is improved; the enzyme loading performance of the resin is improved, the enzyme activity is retained, byproducts in the lactosucrose production process are reduced, the synthesis reaction time is shortened, the stability is good, and the resin can be repeatedly used for multiple times. Meanwhile, the ultrafiltration and nanofiltration membrane separation technology greatly improves the purity of lactosucrose, has the advantages of simplicity in operation, high separation efficiency, no secondary pollution and low energy consumption, and avoids product loss caused by activated carbon adsorption.
