1. Different usages

Yellow rock sugar also has the function of "browning sugar" in cooking, so when you need to "fried sugar color", choose polycrystalline yellow rock sugar, which has a more natural taste. Single crystal white rock sugar is easier to melt and will be more convenient in cooking and processing

2. Different production processes

Polycrystalline yellow rock sugar is white sugar and water heated to 118-120 degrees In this case, it is formed by cooling and crystallizing at a constant temperature for 7 days. Single crystal rock sugar is simply dissolved in white sugar in 80-degree water, cooled down to form a supersaturated solution, and then crystallized.

3. Different colors

Polycrystalline yellow rock sugar is divided by color, mainly including white, light yellow, and light gray;

Single crystal rock sugar is basically White.

4. Different sizes

Due to different production processes, the production of polycrystalline yellow rock sugar is much larger than that of single crystal rock sugar.

Single crystal rock sugar and yellow rock sugar materials:

Single crystal rock sugar is in the shape of regular transparent crystals. It is a new type of rock candy produced in the 1960s. The production process is as follows: put white sugar into an appropriate amount of water, heat and dissolve it, filter it and then put it into a crystallization tank to make the sugar liquid supersaturated. Put in crystal seeds to grow the crystals. After the crystal grains are grown, they are taken out for honey removal and centrifugal drying. It is made by ventilating, drying, sifting and classifying. Single crystal rock sugar does not have the medicinal effects of rock sugar as described by traditional Chinese medicine.

Yellow rock sugar generally refers to old rock sugar. Lao rock sugar, also known as earth rock sugar, old earth rock sugar, yellow rock sugar, lump rock sugar, polycrystal rock sugar, etc., is made from sugar-making intermediate product syrup or finished white sugar, which is dissolved by adding water, removing impurities, clearing the juice, evaporating, concentrating and adding After adding appropriate crystallizing agent, it is gradually cooled and crystallized. After being crushed and dried, it is the finished product. The production cycle is about 7 days.
