Acid insoluble ash is the residue left behind after burning a sample of food or feed with acid to remove organic matter. It provides an estimate of the amount of impurities, such as sand, silica, and other minerals, in the sample that cannot be dissolved in acid. It is often used as an indicator of the purity and quality of the sample.
Ash content and acid insoluble ash are important parameters for assessing the purity and quality of food products. Ash content indicates the amount of inorganic mineral content present, which can affect the nutritional value and authenticity of the product. Acid insoluble ash specifically helps detect the presence of adulterants like sand, silica, or other non-edible substances in food, ensuring consumer safety and regulatory compliance.
The residue left after incirenation of the crude drug is designated as ash. The residue obtained usually represents the inorganic salts naturally occuring in the drug and adhering to it.it varies with in defininte limits according to the soils, it may also include inorganic matter deliberately added for the purpose of adulteration. Hence, an ash value determination furnishes the basis for judging the identity and cleanliness of any drug and gives information relatives to adulteration/contamination with inorganic matter, thus ash values are helpful in determining the quality and purity of drug. The total ash of crude drug reflects the care taken in its preparation. The acid insoluble ash is a part of the total ash that is insoluble in dilute hydrochloric acid. A higher limit of acid-insoluble ash is imposed, especially in cases where silica may be present or where calcium oxalate content of the drug is higher Procedure given in indian pharmacopeia was used to determine the different ash values such as total ash, acid insoluble ash, and water - soluble ash value.Ash is inorganic residue remaining after the water and inorganic matter have been removed by heating in the presence of oxidizing agents, which provides a measure of the total amounts of minerals within the foodsThe acid insoluble ash (AIA) content is the proportion of a sample that is not hydrolyzed by 72% sulphuric acid and is not subsequently volatilized upon the incirenation of this acid insoluble residue.
Acid-insoluble ash determination helps measure the amount of inorganic materials like sand, silica, and dirt present in the food sample. It is important in quality control to ensure that food products meet specific purity standards and to assess the level of contamination, which can affect the safety and quality of the product. High levels of acid-insoluble ash can indicate poor manufacturing practices or adulteration.
To evaluate the insoluble content of a substance.

Milk and milk products, vegetables and fruits should be avoided when following an acid-ash diet because when they are metabolized, they leave acid residue in the body to be excreted in the urine. Acid-ash diets typically consist of large amounts of meat, fish, eggs and cereal.
Yes, soda ash (sodium carbonate) is effective in neutralizing acids because it is a basic compound. When mixed with an acid, soda ash reacts to form water and a salt, ultimately neutralizing the acid. This reaction helps to increase the pH of the solution and reduce its acidity.

The acid ash diet is not a fad, but rather a medically prescribed diet for those who suffer from kidney stones. An indication that the diet is needed is kidney stones.
