China is one of the earliest countries in the world to produce sugar from sugarcane, with a history of more than 2,000 years.

White sugar is composed of almost a single ingredient, sucrose, and the sucrose content of white sugar is generally above 95%.

All plants with high sucrose content can be raw materials for sugar production.

At present, the main raw materials for sugar in the world are sugar cane and sugar beet.

Despite the different raw materials for sugar, there is no difference in quality between cane sugar and beet sugar, and the national standard for white sugar applies to both.

Factories use sugar cane and sugar beet to extract sugar juice, after boiling and concentration, the center separates to form sugar crystals, which are called crude sugar (or raw sugar) and are light brown.

Crude sugar is refined to become white granulated sugar for daily consumption.

In addition to sugar cane and sugar beets, white sugar can also be processed from raw sugar, crude sugar, and other sugars with high sucrose content.

At present, the sugar method or clarification method adopted by countries around the world, mainly lime method, sulfite method and carbonic acid method of three categories.

The lime method can only produce a darker color of crude sugar, while the sulfite method can produce direct consumption of white sugar (the production of white sugar called sulfated sugar).

Although this method is worse than the white sugar produced by carbonic acid method in terms of whiteness and sugar yield, but due to the sulfite method has a shorter process, less equipment and clarifying agent dosage and other advantages, so in the domestic large, medium and small cane sugar mills are still widely used.

In foreign countries, over the past decade, with the increase in consumption of refined sugar, many sugar mills using the sulfite method have changed to the lime method, the production of crude sugar and then soluble refining.

But in the vast majority of developing countries, the sulfite method still occupies an important position.

The use of lime and carbon dioxide as a clarifying agent to clarify the cane juice is called the carbonation method (the sugar produced is called carbonated sugar).

The non-sugar substances removed by the carbonation method are more than the sulfite method, the total recovery rate is also higher, and the purity of the finished sugar is higher, the color value is lower, and it can be stored for a long time without discoloration.

However, the carbonic acid method also has some disadvantages, such as the process is more complex, requires more mechanical equipment; also consumes a lot of lime and carbon dioxide, so the production cost is higher.

Especially in the sugar factory away from the limestone production area is far away, the promotion of carbonic acid method is subject to certain restrictions.

White rock sugar is made by purifying dissolved white granulated sugar and then crystallizing it naturally.

White rock sugar is characterized by its sweetness and moistness to the lungs, crystal clear, and is suitable for use in stews, tonic drinks, and other preparations.

White Rock Sugar is sweet and moisturizing to the lungs.
