Calculation of juice content in a diluted fruit juice beverage

A 1990 amendment to the Food, Drug and Cosmetic Act states that if a food purports to be a beverage containing vegetable or fruit juice, it shall be deemed to be misbranded unless its label bears a statement of the total percentage of such fruit or vegetable juice content. The intent of the present paper is to assist beverage manufacturers in calculating the juice content of their products for the purpose of a label declaration.
