Problems solved by technology

At present, there is no patent introduction on the production process of anhydrous trehalose. In the traditional drying process, fluidized bed is used for material dehydration. Generally, only free water can be removed, and crystal water is difficult to completely remove. High temperature equipment is used to remove crystal water, and the cost is high , it is difficult to promote in the industry

Abstract

The invention relates to a preparation method of trehalose anhydrous. The preparation method comprises the following step: by adopting a trehalose reaction solution prepared from high-concentration malt syrup by enzymatic conversion as a raw material, performing processes such as enzymolysis and impurity removal, activated carbon decolorization, ion exchange, simulated moving bed chromatographic separation and belt-type vacuum continuous drying and dehydration to prepare series products containing trehalose anhydrous with the purity of 50-99.5wt% so as to meet the special requirements of trehalose anhydrous as a drying agent in different fields of drying. A trehalose anhydrous production process disclosed by the invention is simple and low in cost, and can be used for saving energy and reducing consumption in a production process.

Description

technical field [0001] The invention relates to a method for preparing anhydrous trehalose, belonging to the technical field of functional sugar preparation. Background technique [0002] Trehalose is a safe non-reducing disaccharide that widely exists in nature, usually in the form of two molecules of crystal water, and its molecular formula is C 12 h 2 o 11 2H 2 O. Trehalose has no free aldehyde groups, is non-reducible, and is very stable to acid and heat. When it coexists with amino acids and proteins, it will not cause browning even if it is heated. Trehalose also has unique effects of preventing starch aging, preventing protein denaturation, and inhibiting lipid oxidation, etc., and can be used as an excellent food ingredient or food ingredient. At the same time, due to its non-reducing sugar characteristics composed of special disaccharide molecules, it can form a unique protective film on the cell surface under harsh conditions such as high temperature, high col...
