Soybean oligosaccharide products include syrup, granules and powder. The seeds of legumes all contain a certain amount of soybean oligosaccharides, among which soybeans (also commonly known as soybeans) contain the largest amount of soybean oligosaccharides. The industrial production of soybean oligosaccharide is based on soybean whey or pulp water during soybean processing. Commercial-grade soybean oligosaccharides are prepared by means of separation, purification, purification, and drying. 4 The specific process flow is 4:
Soybean → soybean whey or yellow pulp water → ultrafiltration to remove macromolecular substances such as protein → active pulp decolorization

Preparation and Production of Isomaltooligosaccharides
Isomaltooligosaccharides are mainly prepared from starch-rich plants (such as corn, potatoes, rice, etc.) as the main raw materials, and are prepared by a series of methods such as enzyme treatment. 4 The specific process flow is:
Corn, potato, rice → starch → -high temperature amylase jet liquefaction → amylase and -glucosidase saccharification and enzyme transfer reaction → plate and frame filtration → activated carbon decolorization → ion exchange desalination → vacuum concentration → liquid syrup → spray drying → Isomaltooligosaccharide solid product. 4
Preparation and production of xylo-oligosaccharides
The preparation and production of xylo-oligosaccharides are mainly carried out by using hemicellulose-rich plants (such as corn cob, etc.) as raw materials, through a combination of physical pretreatment and biological enzymatic degradation. 4 The specific process is 4:
Corn cob → crushing → pulping → steam explosion → xylanase enzymatic hydrolysis → plate and frame filtration → decolorization of filtrate → separation and desalting → one vacuum concentration
