Sugar is a common food item. The main component of sugar is sucrose itself. But besides it, the corresponding product may contain various impurities. In sugar, their content is allowed up to 0.25%, in refined sugar - up to 0.1%. Cane and beet sugar (granulated sugar, refined sugar) is an important food product. Regular sugar refers to carbohydrates. Starch also belongs to carbohydrates, but its absorption by the body is relatively slow. Sucrose quickly breaks down in the digestive tract into glucose and fructose, which then enter the bloodstream.
