A brief introduction to Sorbitol
1.Sorbitol, molecular formula C6H14O6, molecular weight 182.17. Sorbitol has a pleasant refreshing sweetness, and its sweetness is about 0.6-0.7 times that of sucrose. 1g of sorbitol produces 12.56KJ of calories in the human body. Add as needed in food production.
2.After eating, it does not cause dental caries, is not digested and absorbed by the human body, does not increase human blood sugar, blood lipid content, and does not stimulate insulin secretion. Sorbitol, especially crystalline sorbitol, has been widely used in chewing gum, ginseng lozenges, and cooling lozenges. , Calcium tablets, slimming tea, Kaisailu, diabetic food, etc.
3.Sorbitol has excellent freshness, fragrance, color, moisturizing and emulsifying functions. It is called "glycerin substitute" and can keep the moisture, fragrance and color of yolk pie, fresh cream, toothpaste, cosmetics, tobacco and other products In addition to freshness, sorbitol can be used in almost all areas where glycerol or propylene glycol is used, and even better results can be achieved. Crystalline sorbitol also has good compressibility and is widely used as a tablet carrier.
4.Sorbitol is easily soluble in water, hardly soluble in organic solvents, has good acid resistance and heat resistance, can withstand high temperatures of 200 ℃ and does not change color, and is not prone to Maillard browning reaction with amino acids and proteins when it is formulated. This performance makes Sorbitol is used in the production of baked goods, frozen foods and aquatic product processing.
5.Sorbitol can combine with metal ion chromium such as AL3+ to prevent its precipitation, and has a certain degree of mutual solubility with coatings. It is used to produce environmentally friendly alkaline etching agents for aluminum profile processing.
6.As a chemical synthesis intermediate, sorbitol can be used to produce chemical products such as sparing, adhesives, alkyd resins, polymers, plastic transparent agents and coagulants.
7.As a medicinal intermediate, Sorbitol can be used to produce vitamin C, compound amino acids, diuretic preparations, nitrated sorbitol esters and other drugs.
With the development of industrial technology, the proportion of industrial products made from polysaccharide alcohols (including xylitol, sorbitol, maltitol, mannitol, etc.) as raw materials is constantly increasing, especially in the food industry. Healthy food ingredients needed by different groups of people, such as anti-caries foods, foods for diabetic people, foods for hyperlipidemia and obesity patients, etc. Sugar-free foods popular in developed countries refer to sweet foods in which sucrose or glucose is replaced by polysaccharide alcohols. The most eye-catching polysaccharide alcohol consumption is sorbitol. Due to its wide source, simple process and low cost, it has been widely used in food, daily chemical, pharmaceutical, surfactant, alkyd resin and other industries. At present, the world's annual output of sorbitol is about 800,000 tons, accounting for nearly 1/3 of the world's total consumption of polysaccharide alcohol, which shows its important position in industrial applications.
Industrial production of sorbitol generally uses glucose or starch saccharification liquid, which is produced by hydrogenation and reduction under the catalysis of nickel catalyst. Commercial sorbitol has two types: powdered crystal and liquid. The content of sorbitol in liquid sorbitol is about 50-70%.
