Problems solved by technology

[0005] The problem in the preparation of ultra-high maltose syrup by chromatographic separation is that the maltose syrup obtained by chromatographic separation contains more maltotriose and maltotetraose or more glucans above tetrasaccharides, or more glucose, so it is difficult to obtain simultaneously Ultra-high maltose syrup with maltotriose, maltotetraose and glucose removed and with a maltose content of more than 98%

Abstract

The invention provides a preparation method of superhigh malt syrup of which the maltose content is higher than 98%. The preparation method mainly comprises the following steps: preparing malt syrup, carrying out chromatographic separation, carrying out yeast fermentation to remove glucose, and separating yeast cells with a ceramic membrane to obtain the superhigh malt syrup in which the maltose content on dry basis is higher than 98%. The invention adopts the conventional chromatographic separation resin, thereby avoiding the steps of resin pretreatment, transformation and the like, and being efficient and quick; the yeast rapid fermentation is adopted to remove glucose, and thus, the method has the advantages of fewer byproducts and mild reaction conditions and is convenient to operate; the maltose content in the obtained product is higher than 98%; and meanwhile, maltotriose, maltotetrose, glucan tetrasaccharide above, and other miscellaneous glucoses are removed.

Description

technical field [0001] The invention belongs to the technical field of biochemical industry, and in particular relates to a preparation method of ultra-high maltose syrup. Background technique [0002] Maltose syrup is a kind of starch syrup that uses refined starch as raw material, liquefies and saccharifies with enzyme preparations, and is refined and concentrated. Trisaccharides, maltotetraose and dextran with more than four sugars, etc. Maltose syrup with a maltose content (the percentage of maltose in the total dry matter) of more than 80% is called ultra-high maltose syrup. In recent years, with the popularization of chromatographic separation technology, the content of maltose in maltose syrup has reached 87%-90% in large-scale production, and the content of maltose in laboratory technology can reach 94%-95%. Ultra-high maltose syrup is used more and more in food and medicine. In particular, ultra-high maltose syrup with a content of more than 98% can be used to pr...
