Moisture-keeping syrup and preparation method thereof

Abstract

A preparation method of moisturizing syrup belongs to the moisturizing technical field. The preparation method takes starch or starch milk as raw materials and adopts Amano AMT1.2L and Genencor OPTIMAX L-1000 for saccharification and production of the moisturizing syrup after liquefaction, the maltose content in the syrup is 13-20 percent, maltotriose is more than 60 percent, oligosaccharides more than tetraose are lower than 18 percent (as the preparation process detects that the triose content is 68 percent, the invention turns to emphasize the contents of two components of the triose and the tetraose), and the glucose is lower than 5 percent. The preparation method adopts pulp conditioning liquefaction, Amano AMT1.2L and the Genencor OPTIMAX L-1000 saccharification, membrane filtration and decolorization, continuous counter-current ion exchange, multi-effect plate-typed vacuum evaporation and concentration and other and advanced production technologies for simplifying process, saving energy and reducing consumption during the implementation process, thereby realizing the environmental friendly and high-efficient production of the special syrup for moisturizing.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a moisturizing syrup and a preparation method of the moisturizing syrup. Background technique [0002] In food (such as Shaqima, cake, bread), medical and sanitary products and daily chemical products, the quality of the selected moisturizer has a very important impact on the quality of the product, especially the role of the moisturizer in food directly Affect the shelf life, taste and shelf life of the product. [0003] Humectant is the moisture retention agent of the product, which plays an important role in maintaining the stability of the product system. At present, the most commonly used natural moisturizers such as hyaluronic acid (HA) and amino acid moisturizers such as methylglycineproline, etc., have good moisturizing effects, but their sources are relatively scarce, which limits their scope of application; while the commonly used chemical synthesis Moisturi...

AI Technical Summary

Problems solved by technology

However, the fermentation method of maltotriose has a low conversion rate of strains; although the chemical synthesis method has high purity, it is difficult to carry out industrial production, and the pollution is serious; the conversion efficiency of most enzyme conversion methods is also relatively low, especially the content of maltotriose is low. Relatively low, the content is generally lower than 40%, and the tetrasaccharide content is generally lower than 12%, which cannot obtain the ideal moisturizing effect
