Problems solved by technology

At present, most manufacturers of xylo-oligosaccharide powder need to spray-dry the syrup to obtain xylo-oligosaccharide powder. However, the xylo-oligosaccharide powder produced by this process is very easy to absorb moisture and form lumps. It needs to be dried immediately after spraying the powder. Packaging, otherwise it will absorb moisture and become sticky. In addition, although the production of xylooligosaccharides by spray drying is relatively high, the energy consumption is very high

Abstract

The invention discloses a preparation method of energy-saving moisture-absorption-resisting xylooligosaccharide powder. The preparation method comprises the following steps of: (1) taking an xylooligosaccharide solution, adding active carbon, stirring and decolorizing, filtering after the decolorizing, so as to obtain a decolorizing solution, and adding de-ionized water in the decolorizing solution, so as to obtain the xylooligosaccharide solution after passing through resin for purifying; (2) placing the xylooligosaccharide solution into an evaporator, so as to obtain an xylooligosaccharide concentrated solution; and (3) throwing the xylooligosaccharide concentrated solution into a vacuum belt drier for dry, and then milling, so as to obtain the moisture-absorption-resisting xylooligosaccharide powder. The preparation method provided by the invention comprises the advantages that (1) the process is simple, and the operation and the adjustment are convenient; (2) the moisture absorption resisting capability of the obtained product is high, the storage and the transportation are convenient, and the relatively good flowing property is kept; (3) the intelligent degree of automatization is high, the labour is saved, and the labour intensity is reduced; and (4) the energy consumption is low, and the cost is low.

Description

technical field [0001] The invention relates to a method for preparing an energy-saving anti-moisture absorption xylo-oligosaccharide powder, which belongs to the field of functional sugar alcohols. Background technique [0002] Xylooligosaccharides, also known as xylooligosaccharides, are functional polymeric sugars formed by combining 2-7 xylose molecules with β-1,4 glycosidic bonds. Xylo-oligosaccharide is a powdery functional sugar product obtained after enzymatic hydrolysis of corncobs, purification and concentration. At present, most manufacturers of xylo-oligosaccharide powder need to spray-dry the syrup to obtain xylo-oligosaccharide powder. However, the xylo-oligosaccharide powder produced by this process is very easy to absorb moisture and form lumps. It needs to be dried immediately after spraying the powder. Otherwise, it will absorb moisture and become sticky. In addition, although the production of xylooligosaccharides by spray drying is relatively high, the e...
