1, the connection between them
Both rock sugar and white sugar are extracted from sucrose plants, but there is still a connection between white sugar and rock sugar. Rock sugar is made from white sugar after reprocessing, and its purity is higher.
2, the difference between the two
White sugar is what we usually call white sugar. Its shape is fine and granular, while the crystal of rock sugar is generally massive, so white sugar has certain differences in appearance. Secondly, the purity of white sugar is not as high as that of rock sugar. Although sugar and rock sugar come from the same family, they also have some differences in efficacy. White sugar is sweet and flat. Proper consumption can promote the absorption of calcium by human body, and can remove bad breath and promote body fluid production. Besides being used as a flavoring agent, white sugar can also be used to wash face, which has the beauty effect of whitening and exfoliating. Rock sugar is also sweet and flat. Its main functions are moistening the lungs and relieving cough, nourishing yin and moistening dryness, and removing fire. Besides, it can also tonify the middle energizer, invigorate the spleen and regulate the stomach.
3, warm tips
No matter what kind of sugar it is, it is not suitable for excessive consumption, and diabetics and hypertensive patients must avoid eating. Both sugar and rock candy need to be sealed in a ventilated and cool place, especially in summer, where high temperature can easily cause them to melt and breed bacteria. If there are melted water drops on the surface of sugar and rock candy, they can be restored by wind blowing and low temperature, but if the melting degree is great, it is best not to eat them.
