The difference between white rock sugar and yellow rock sugar is as follows:

1. Different production processes

1. Yellow rock sugar is also called old rock sugar or earthy rock sugar, which is derived from white granulated sugar. As a raw material, after adding water to heat and dissolve, then removing impurities, clearing the juice, evaporating, concentrating and adding appropriate crystallizing agents, then gradually cooling and crystallizing, crushing and drying the refined sugar, which is a rough process.

2. White rock sugar is made on the basis of yellow rock sugar through further decolorization, multiple refining, impurity removal, and concentration processes. Most of them are bleached with sulfur dioxide and are finely processed. However, The original sugar cane components are also lost more.

2. Different crystal states

1. Yellow rock sugar is a polycrystalline rock sugar with irregular crystals, relatively low degree of refining, relatively large size and different sizes, and slightly glossy. Low.

2. White rock sugar is single crystal rock sugar. The crystals are uniform, the size is basically the same, the texture is hard, and it is durable in storage.

How to store rock sugar:

1. Before storage, scatter the rock sugar on a plate and expose it to the sun for an hour to evaporate the water in the rock sugar and keep the rock sugar itself dry. , then place in a cool, dry place to cool to room temperature.

2. Wipe the inside and outside of the jar you intend to store the rock sugar in, and place it in a cool, dry place for later use. You can put a label on the jar to indicate the storage start date, which will help you better control the storage time of rock sugar.

3. Put the dried rock sugar into jars. Do not fill each jar too full, leaving a certain margin. Tighten the lid and store in the refrigerator.
