Problems solved by technology

The demand for crystalline fructose in the pharmaceutical industry will continue to expand. Fructose injection is a new generation of high-energy nutritional infusion that does not depend on insulin; the main preparation processes of existing fructose are as follows: 1. Using apples as raw materials to produce crystalline fructose; 2. Use inulin as raw material to produce crystalline fructose; 3. Use starch as raw material to produce crystalline fructose; 4. Use sucrose as raw material to produce crystalline fructose; these methods all require more complicated process flow, not only the production efficiency is low , and the overall cost is high, so it cannot meet the amount of fructose required by the market, so how to simplify the fructose preparation process, improve fructose production efficiency, and reduce production costs is the research direction of this industry

Abstract

The invention discloses a method for preparing fructose by vacuum hydrolysis of burdock with solid acid, which comprises the following steps: obtaining burdock powder, mixing the burdock powder with distilled water to form a burdock powder mixed solution, selecting strong acid cation exchange resin as solid acid, and sequentially treating the solid acid with a NaCl solution, a HCl solution and a NaOH solution; and proportionally mixing the treated solid acid and burdock powder mixed solution, injecting into a rotary evaporator, setting the vacuum degree, temperature, rotating speed and hydrolysis time of hydrolysis conditions, concentrating after hydrolysis to obtain a fructose concentrated solution, and carrying out ethanol temperature difference crystallization treatment to finally obtain the crystalline fructose. According to the method, synanthrin in burdock can be hydrolyzed to obtain fructose with very high content without isomerization, and the crystal nucleus of crystalline fructose has relatively good uniformity, so that the fructose preparation process can be simplified, the fructose production efficiency can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a method for preparing fructose by vacuum hydrolyzing burdock with solid acid, and belongs to the technical field of fructose preparation. Background technique [0002] Fructose is one of the commonly used sugars. It naturally exists in honey, Jerusalem artichoke and other Compositae plants, and exists in a large amount in the juice of various fruits in a free state. It is the main sugar in fruit juice. The glycolysis process of fructose and glucose after entering the human body is not the same. In the process of glycolysis, glucose needs to be catalyzed by two key enzymes, hexokinase and 6-phosphofructokinase-1 (PFKI), to generate 1,6-di Fructose phosphate, of which PFKI is the most important rate-limiting enzyme in the glycolysis process, and insulin can induce its production. Fructose is mainly metabolized through the 1-phosphate fructose pathway in cells, and two key enzymes, fructokinase and 1-phosphate fructosidase, are ...
