Ash (also referred to as "crude ash," "inorganic matter" or "incinerated residue") is a regulatory or technical term that represents the mineral content of a food. Ash is what remains of a pet food after a sample is incinerated as part of a laboratory analysis.
The organic content (i.e., carbohydrate, fiber, fat and protein) will be totally combusted and only the minerals will remain (e.g., calcium, phosphorus, magnesium, etc.). The mineral content in pet food comes from ingredients and supplements added to the formula. Some regulatory agencies require pet food companies to declare ash content on the pet food label.
