Abstract

The invention provides a method for preparing high maltose oligosaccharide. The method includes the following steps of a, saccharifying, wherein after starch is liquefied, a sugar solution is saccharified through the combined effect of maltose trisaccharidase, barley beta-amylase and pullulanase to generate a product with the malt sugar content of about 40% and the maltotriose content of about 40%; b, chromatography separating and purifying, wherein the saccharified and concentrated sugar solution is purified with the chromatographic separation technology, and the mass fraction of feeding ranges from 55% to 60%; under the condition of the running temperature of 60 DEG C of a system, the malt sugar, the maltotriose and glucose are separated, and a feed solution with the component (the maltotriose and the malt sugar) content of 92% or above is obtained; c, refining, wherein the obtained high maltose oligosaccharide solution is subjected to activated carbon decoloring filtering, ion exchange desalting and vacuum concentrating, and the high maltose oligosaccharide product is obtained. The prepared high maltose oligosaccharide has the advantages of being high in purity, excellent in hygroscopicity and moisturizing performance, low in sweetness, good in heat resistance and acid resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of starch sugar derivatives, and in particular relates to a preparation process of high maltose oligosaccharides. Background technique [0002] Carbohydrates that are hydrolyzed into 3-8 molecules of monosaccharides per molecule of starch or maltodextrin are called maltooligosaccharides, and some people classify carbohydrates that are hydrolyzed into 3-10 or even 20 molecules of monosaccharides into this category. The one composed of three glucose molecules is called maltotriose, and the one composed of two glucose molecules is called maltose. Maltose and maltotriose are collectively called high maltooligosaccharides, both of which are α. D-glucose is α-1→4 and α -1→6 glycosidically bonded. High maltose oligosaccharides is a new type of sugar source that integrates health care and nutrition, which is made from refined corn starch using advanced biotechnology. [0003] The biggest feature of ...
