4 Analysis of Ash and Minerals 41 Introduction The “ash content” is a measure of the total amount of minerals present within a food, whereas the “mineral content” is a measure of the amount of specific inorganic components present within a food, such as Ca, Na, K and ClDetermination of the ash and mineral content of foods is important for a number of reasons:
