Rock sugar is further refined from white sugar. Rock sugar is a crystallized reproduction of sugar. Naturally occurring rock candy has white, yellowish, light gray and other colors. In addition, there are all kinds of colored rock candy added with food pigments on the market (mainly for export), such as green, blue, orange, reddish, crimson and other colors. Because its crystal is like ice, it is named rock sugar. Also known as "frozen food".
Second, the difference and connection between rock sugar and white sugar:
1, difference:
(1) raw materials are made in different processes.
Rock candy is made by melting white sugar into liquid, firing, removing impurities, and then evaporating water to make it crystallize naturally at about 40℃, or by freezing crystallization. Good quality rock candy is even white or yellow, translucent, with crystal luster, pure and sweet texture, no odor, no peculiar smell and no obvious impurities. The yellow rock candy is of poor quality. People should use clear white rock sugar when eating nourishing food.
White sugar is almost composed of sucrose, and the sucrose content of white sugar is generally above 95%. All plants with high sucrose content can be used as raw materials for sugar production.
(2) the taste is different
Rock sugar is sweet but not greasy, and sugar is sweet and greasy; Generally, boiled sugar water is mainly rock sugar, and cooking seasoning is mainly white sugar.
(3) Different efficacy
Rock sugar is mild, has the effect of relieving cough and resolving phlegm, and is widely used in high-grade tonics and health products produced in food and pharmaceutical industries. Old people can also relieve thirst by containing crystal sugar.
White sugar is flat, sweet, moistening lung, promoting fluid production, invigorating middle energizer, clearing away heat and dampness, resolving phlegm and relieving cough, detoxicating, sobering up, reducing turbidity and refreshing the mind; Can be used for treating abdominal pain due to deficiency of the middle energizer, diarrhea due to spleen deficiency, lung dryness and cough, dry mouth and thirst, beriberi, scabies, bittern poisoning, scrotal eczema and other diseases. In addition, sugar has antibacterial and antiseptic effects.
2. Contact:
(1) Rock sugar is the reprocessing of white sugar. Rock sugar is an ice-like crystal made by frying white sugar. It is a large-particle crystal sugar made by dissolving sucrose and protein raw material formula, cleaning and recrystallization.
(2) The composition of rock sugar is glucose containing crystallization water, which is the same as that of white sugar decomposed in the body, so it can replace white sugar; Because of its high purity and unique dietotherapy effect, it is superior to white sugar and quite competitive in the market.
Extended data
The quality of rock sugar is pure, and it is not easy to deteriorate. Besides being eaten as candy, it can also be used as a high-grade food sweetener, preparing drugs, impregnating alcohol and nourishing adjuvant drugs. The general population can eat it, and diabetics should not eat it.
Proper consumption of white sugar can improve the body's absorption of calcium, but after eating white sugar, you should rinse your mouth or brush your teeth in time to prevent dental caries. In addition, it is not easy for diabetics to eat white sugar directly, and it is best to replace it with sweeteners.
