Brown sugar refers to the finished sugar of sugar cane and honey, which is made by squeezing and concentrating sugar cane. Brown sugar is divided into flake sugar, brown sugar powder and bowl sugar. According to the different crystal particles, it contains almost all the components in sugarcane juice because it is not highly refined. Besides the function of sugar, it also contains vitamins and trace elements, such as iron, zinc, manganese and chromium. Its nutrient content is much higher than that of white sugar. The famous brown sugar producing areas are Gongcheng Yao Autonomous County in Guilin, Guangxi, Yunnan and other places.
