Abstract

The invention relates to a method for preparing crystalline fructose, which comprises the following steps in sequence: firstly, chromatographically separates the fructose solution; performs ion exchange and nanofiltration operations on the obtained fructose solution, and then passes the obtained fructose solution through a double-effect plate evaporator and a scraper respectively. The evaporator is used for concentration; the concentrated fructose solution is mixed with ethanol, and finally crystallized, centrifuged and dried to obtain fructose crystals. The preparation method of the crystalline fructose of the present invention adopts the nanofiltration separation process, and the impurities that affect the crystallization and the quality of the finished product are removed before the crystallization, which improves the product quality and crystallization yield; the combination of a high-efficiency plate evaporator and a scraper evaporator reduces the The evaporation temperature of fructose and the residence time in the evaporator can effectively prevent the thermal decomposition and complex reaction of fructose. Compared with the fructose crystallized in the prior art, the crystalline fructose produced by the method has high fructose purity, uniform crystal particles, good color, high crystallization rate and low unit cost.

Description

Technical field [0001] The invention relates to the field of sugar production, in particular to a method for preparing crystalline fructose. Background technique [0002] At present, there are three industrial production methods of crystalline fructose according to the source of raw materials: 1. Using sucrose as raw material, the fructose liquid is obtained through hydrolysis, and the fructose and glucose are separated by chromatography to obtain a high-purity fructose liquid. Fructose undergoes ion exchange and concentrated crystallization to obtain crystalline fructose. 2) Using corn starch to produce glucose as raw material, the isomerization reaction is carried out by glucose isomerase to obtain fructose liquid. After chromatographic separation, fructose and glucose are separated to obtain high-purity fructose liquid, and then high-purity fructose liquid After ion exchange and concentrated crystallization, crystalline fructose is obtained. 3) Using inulin as a raw material...
