Classification: white sugar, brown sugar,white sugar, single crystal sugar, crystal sugar, brown sugar, sugar, borneol, frosting liquid syrup etc;
Chemical property:
The crystallized sucrose is heated to **0 C, and the thermal decomposition will melt into the thick and transparent liquid, when cooling it will re crystallized;When the heating time is prolonged, sucrose is decomposed into glucose and dehydrated fructose;At a high temperature of **0 - **0 C, the sucrose will dehydrate and condensate to caramel;Caramel is further heated to produce carbon dioxide, carbon monoxide, acetic acid,acetone and so on;Under wet conditions, sucrose is decomposed at **0 C, releasing water and darkening the color;When the sucrose solution is heated for a long time under normal pressure, the dissolved sucrose will slowly decompose into the equal amount of glucose and fructose, that is the conversion effect occured;
Application:
Food industry: sweetener, toner, modifier, puffing agent, yeast nourishing agent, extension of food preservation period, etc.
