1. Different production processes and different structural properties

Rock sugar is made from hot refined saturated sugar solution as raw material, which is dissolved, impurities removed, boiled, and finally crystallized. White rock sugar is single crystal rock sugar because it has gone through multiple processes for decolorization and sulfur dioxide bleaching. Red rock sugar has not undergone complicated decolorization and is basically polycrystalline rock sugar created by traditional techniques. The cross-sections of polycrystalline and single crystal are different.

2. Different uses

Red rock sugar has a darker color because it has not decolorized. It is usually used to color food, such as sweet and sour pork ribs, braised pork, etc. As for white rock sugar, most people prefer to make drinks to increase the sweetness and are widely used in food processing.

3. Different nutritional contents.

Since red rock sugar has not been decolorized, the content of natural sugar cane ingredients is much higher than that of white rock sugar, and the sweetness is much sweeter than white rock sugar. It has richer nutritional value and is more healthy and hygienic. Therefore, more and more people choose yellow rock candy.
