Sugar is a term for a class of edible crystalline carbohydrates, mainly sucrose, lactose, and fructose characterized by a sweet flavor. In food, sugar almost exclusively refers to sucrose, which primarily comes from sugar cane and sugar beet. Other sugars are used in industrial food preparation, but are usually known by more specific names—glucose, fructose or fruit sugar, high fructose corn syrup, etc.

Raw materials:Originally, people chewed sugarcane raw to extract its sweetness

Uses:More recently it is manufactured in very large quantities in many countries, largely from sugar cane and sugar beet. In processed foods it has increasingly been supplanted by corn syrup.
