Description

Preparation method of functional sucrose with blood sugar reducing function
Technical Field
The invention relates to sucrose preparation, in particular to a preparation method of functional sucrose with a sugar-reducing function, belonging to the field of functional sugar production and processing.
Background
Diabetes mellitus is a chronic metabolic disease mainly characterized by hyperglycemia caused by defects in insulin secretion of the body or impaired biological action of the body, or both, and is one of the biggest threats to human health in the 21 st century. According to the seventh edition of Diabetes Atlas data published in the international Diabetes union idf (international Diabetes federation)2015, 4.15 million adults with Diabetes mellitus, 54 million children with type 1 Diabetes mellitus, by 2040 years will rise to 6.42 million, and 6370 to 11970 million dollars per year will be spent on Diabetes therapy. In China, 1.09 million adults have diabetes and are the first place in the world, so the prevention and treatment of diabetes in China become one of the most urgent problems to be solved.
Sucrose (D (+) -Sucrose), formula: c12H22O11Relative molecular mass: 342.3, common white sugar, brown sugar, crystal sugar and cubic sugar are all cane sugar. Since the sugar has pure and long-lasting sweetness and is a natural organic sweetener, the production and the eating have been for thousands of years, and the long-term eating proves that the sugar is a safe natural sweetener, so the sugar is one of the basic food additives for human beings. However, since sucrose is composed of one molecule of glucose and one molecule of fructose, and is easily decomposed into fructose and glucose by digestion in the human body, synthetic or derivative sweeteners are generally consumed by diabetic patients to prevent blood sugar from rising.
In order to solve the problem that the group of diabetes patients can eat sucrose safely, a plurality of sucrose substitutes are available at present, and corresponding sucrose derivatives are prepared by several sucrose modification technologies, such as: chinese patent No. CN1453284 discloses a method for synthesizing sucralose, comprising the steps of adding N, N-dimethylformamide solution into sucrose as a raw material, carrying out ester exchange reaction with ethyl acetate under the catalysis of a sulfate solid acid catalyst or a sulfate solid adsorbed on a polymer carrier to generate sucrose-6-acetate, and carrying out chlorination and alcoholysis reaction on the sucrose-6-acetate to generate sucralose; chinese invention patent CN103497944A discloses a method for preparing sucrose isomerase, which adopts ultrasonic wave crushing technology to prepare cell wall synthetase containing sucrose isomerase activity as catalyst, to convert sucrose into isomaltulose, and needs to activate the strain of sucrose isomerase producing strain in seed culture medium; then transferring the activated strain to a fermentation medium for culture, and carrying out sucrose isomerase production; then, breaking the sucrose isomerase producing strain by ultrasonic waves and collecting broken cells to obtain cell wall fused sucrose isomerase, and then carrying out sucrose isomerization production by the sucrose isomerase. Although the method modifies the sucrose from different technical angles, the sucrose is not suitable for being hydrolyzed in human bodies, so that the sucrose is suitable for people with diabetes to eat, the research results published by the scientific institute 2014 of Wilzmann, Israel in < Natural > journal prove that the artificial sugar substitute disturbs the balance of intestinal flora and finally reduces the capability of the digestive system to metabolize sugar, so that the non-caloric artificial sugar substitute is more likely to cause diabetes and obesity than Natural sugar.
