Sugar can be divided into white sugar, brown sugar and yellow sugar by color. The different shades of color are due to the different degree of impurity removal in sugar making. White sugar is refined sugar, and its purity is generally above 99%. Yellow sugar contains a small amount of minerals and organic matter, so it is colored; Brown sugar is unrefined coarse sugar with a deep color.
According to the particle size, sugar can be divided into white sugar, soft sugar, cube sugar, rock sugar and so on. White sugar and soft sugar are both called white sugar, and the sucrose content is generally above 95%. White sugar is uniform and neat, hard, loose and dry, and free of impurities. It is the most sucrose-containing and purest variety in sugar, and it is also a kind of sugar that is easy to store. Compared with sugar, soft white sugar has fine crystal particles, more water content, soft and moist appearance, and fast melting in the mouth. It is suitable for direct sprinkling and dipping in food and snacks, and it is not easy to keep because of its high water content, so it is best to process it into small packages. Crystal sugar is made from white sugar by dissolving in water, removing impurities, clearing juice, evaporating, concentrating, cooling and crystallizing.
