Production methods

1 Hydrogenation method. Sorbitol is mainly obtained by catalytic hydrogenation of glucose and direct hydrogenation of starch sugar. Sucrose is also used as raw material to produce sorbitol, but it needs to be hydrolyzed to glucose first and then obtained by hydrogenation reaction.

2. Electrochemical method. Sorbitol was prepared from glucose and fructose by electrolytic reduction.

3. Biological fermentation. Using glucose and fructose as raw materials, glucose and fructose are converted into sorbitol by microbial enzymes.

use

Sorbitol is a kind of chemical raw material with a wide range of uses. It can be used as sweetener, humectant, excipient and preservative in food, daily chemical, medicine and other industries. At the same time, sorbitol has the nutritional advantages of polyol, such as low calorific value, low sugar and anti-dental caries
