Starch is the most common carbohydrate in the human diet and is contained in many staple foods. The major sources of starch intake worldwide are the cereals (rice, wheat, and maize) and the root vegetables (potatoes and cassava).
Arrowroot and tapioca starch are very similar in source, manufacture and paste characteristics. As a result they are often confused. In fact, some commercial arrowroot starch marketed is actually tapioca starch. The extraction and refining is similar to cassava (tapioca).
