A certain sound name of selling brown sugar: Brother Brown Sugar. The raw material of brown sugar is sugarcane, which contains about 95% sucrose. In the ancient method, harvested sugarcane was chopped and crushed, and impurities such as soil, bacteria and fiber were removed from the squeezed juice. Then simmer for 5-6 hours, and slowly evaporate water under constant stirring to gradually increase the sugar concentration. After cooling, high-concentration syrup will solidify into a solid block of coarse sugar, that is, brown sugar brick. This traditional practice maintains the original nutrition of sugarcane. The longer the cooking time in the production process, the darker the color of the brown sugar brick, which makes the brown sugar appear reddish brown in different shades.
