acid insoluble ash indicates the amount of silica present in the given sample
The procedure for ash content determination in food samples begins with the selection of a sample that is believed to be representative of the entire portion. Then, the food is vaporized by dry ashing causing all minerals and water to be burned off.
Usually wet food with a low ash content.
Ash content is determined by calcination and deionized water is not necessary.
Yes, incinerator ash is commonly contaminated with highly concentrated toxic substances.
To evaluate the insoluble content of a substance.
The amount of ash produced during combustion relative to the amount of fuel fed into the wood pellet stove. Ash content is one indicator of quality for wood pellet fuel. Ash content for wood pellets should be between one and three percent. 

ASH 'the incombustible inorganic residue remaining after incineration; generally the mineral content of the food' * Contrary to popular belief ash in pet food has not been collected from a fire place and added for bulk! In pet food the constituents are broken down into several components: Moisture, protein, fat, and sometimes fibre and carbohydrates (often found in lower quality foods). Anything that does not come into one of these categories is called by the general term 'ash'. Therefore ash contains minerals and vitamins and is essential for your pet's health. It is called ash because when the food is burned (to determine its analysis) carbohydrate, fibre, fat and protein are all incinerated. Ash is the part of the food that remains after incineration. Too much ash harms cats. the amount of ash must be documented on all cat food. cats with kidney disease or past UTI should not have diets with ash.
Fixed Carbon by Difference = 100 - (Volatile Content + Ash Content + Moisture Content)
Carbon dioxide, water, ash.
nothing because people haven't invented that kind of dog food that's because the people in this world are idiots. I'm talking about CAT FOOD not Dog Food
