It turns out that the method of making white sugar was invented by China.

The method of making white sugar was not invented by China, but was introduced from India. As early as the pre-Qin period, people in China learned to make syrup from sugarcane, but the sugar at that time was not as pure as white sugar. In the Tang Dynasty, due to the introduction of Indian sugar technology, China began to produce white sugar.

White granulated sugar is a refined sugar, and its production steps mainly include the following steps:

1. Sugar cane juice: First, you need to peel the sugar cane and juice it.

2. Precipitation and filtration: After juicing, there will be some impurities in the juice, which need to be precipitated for a period of time and then filtered out.

3. Heating and concentration: pour the sugarcane juice into the pot and heat it, constantly stirring it to prevent the bottom from being burnt. When heated to a certain extent, the water will evaporate and the sugar solution will become sticky. Continue to heat and stir until the sugar solution becomes very viscous and can be pulled out.

4. Cooling and solidification: pour the viscous sugar solution into the mold, and after cooling for a period of time, the sugar solution solidifies into a block.

5. demoulding processing: take the solidified sugar out of the mold and carry out necessary processing, such as grinding and cutting, to get our common white sugar.

Although the method of making white sugar was not invented by China, in the history of China, the "yellow mud sugar pouring method" invented in the middle of Ming Dynasty is a very famous method of making white sugar. In this method, sugar cane is squeezed and boiled over a fire. Firstly, the brown sugar is made according to the conventional method, then the prepared brown sugar is put into a tile bucket for caking, and then the yellow mud water is poured into the bucket for reaction to obtain white sugar. After this method was invented in Fujian, it quickly spread to Daming and had an important influence in the history of sugar production in the world.
