QUID stands for Quantitative Ingredient Declaration. In certain circumstances it is necessary to state on the label the quantity, in percentage terms, of an ingredient or category of ingredients used in the manufacture or preparation of a foodstuff. The percentage quantity should be in or next to the name of the food or be in the list of ingredients. It applies to all foods, including beverages, with more than one ingredient unless especially exempt. It also applies to those products exempt from ingredients listing. For these products the ingredient quantity will need to be given close to the name of the product.
