Old rock sugar is also known as rock sugar, old rock sugar, yellow rock sugar, block rock sugar, polycrystalline rock sugar, etc. It is made from syrup, an intermediate product of sugar production, or finished white sugar. After adding water to dissolve, removing impurities, clearing juice, evaporation, concentration, and adding appropriate crystallizing agents, it is gradually cooled and crystallized. After being crushed and dried, it is the main finished product. Its production cycle is about 7 days. Rock sugar is easy to absorb water and get damp, so it should be placed in a cool and ventilated place. If the rock sugar is found to be damp and watery, it can be blown dry with an electric fan or exposed to the sun until it is dry. If the surface is water-melting (i.e., it is relatively sticky), it is not easy to handle at home and it is easy to breed bacteria, so it is best not to eat it.

Yellow rock sugar or white rock sugar, which one moisturizes the lungs

According to traditional Chinese medicine, rock sugar is sweet and mild in nature. It enters the spleen and lung meridians. It has the effects of nourishing the middle and replenishing qi, harmonizing the stomach and moistening the lungs, relieving cough and reducing phlegm, and nourishing yin and stopping sweating. The Compendium of Materia Medica believes that rock sugar has a good tonic effect. The effects of yellow rock sugar and white rock sugar are almost the same, but yellow rock sugar is better because it contains more natural ingredients from sugarcane.

Is it better to use yellow rock sugar or rock sugar for stewing desserts?

There is not much difference between the two, but it is recommended to use white rock sugar. Rock sugar is made from white granulated sugar, which is made through re-dissolving, purifying and recrystallization. Rock sugar is divided into two types: white rock sugar and yellow rock sugar. White rock sugar is the main export, and the export amount of yellow rock sugar is very small. There is not much difference between white rock sugar and yellow rock sugar. The chemical composition is the same, and yellow rock sugar contains slightly more impurities.
