ISOMALTOSE(Cas 499-40-1) Usage

Preparation |
The production methods of functional oligosaccharides generally include: extraction method, whole enzyme method, acid-base method and chemical synthesis method. The extraction method is generally used for the manufacture of soybean oligosaccharides, the acid-base method is mainly used for the production of lactulose, and the chemical synthesis method is also limited to the functional research of oligosaccharides. And now the industrially produced isomaltooligosaccharides are obtained by catalyzing the reaction of α-amylase and α-glucosidase by using high-concentration glucose syrup prepared from starch raw materials as the substrate. |
