The ingredients of rock sugar and white sugar are the same. Why is the price difference so much? Because rock sugar is a crystallized reproduction of sugar, and its water content is less than that of white sugar. Rock candy is made from white sugar through re-dissolution, purification and recrystallization, and the production process is more complicated than that of white sugar. Moreover, it takes a certain time to crystallize rock candy, and the production cycle is much longer than that of white sugar.

Generally speaking, according to different crystallization processes, rock candy can be divided into single crystal rock candy and polycrystalline rock candy. Single crystal rock candy has high purity, uniform sugar particles, white and shiny, while polycrystalline rock candy has relatively low refining degree, large size and slightly low gloss. The old rock candy, earth rock candy and yellow rock candy we often say are one kind of polycrystalline rock candy. The yellow rock candy is yellow because it has not been decolorized during processing. Therefore, the difference between different grades of rock candy is mainly the purity of sucrose, and the overall difference is not very big.

At present, the effect of rock sugar is that rock sugar is dehydrated and refined from white sugar, which is mild in nature and has the effect of relieving cough and resolving phlegm, and its unique curative effect can not be replaced by other sugars.

The efficacy of white sugar Chinese medicine believes that white sugar is cold, which can clear lung, moisten dryness, soothe liver, tonify spleen and promote fluid production, benefit throat and relieve hangover.

Their differences mainly lie in their different shapes. The crystal of rock sugar is larger, and the crystal of white sugar is smaller, so their efficacy is quite different.

In fact, rock sugar has also been an auxiliary material for brewing pharmaceutical wine and stewing supplements since ancient times. Such as rock candy tremella soup, rock candy Sydney soup, rock candy bird's nest, etc., but it should be noted that it is not suitable for excessive consumption. People with hypertension, arteriosclerosis and coronary heart disease, as well as pregnant women and children, should eat less; Patients with diabetes and hyperglycemia must avoid eating. Usually, they can't eat too much rock sugar, but it is ok to eat occasionally. Eating too much sweets is not good, and it is not good for the body.
