    4. Analysis of Ash and Minerals . 4.1 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 Cl. Determination of the ash and mineral content of foods is important for a number of reasons:

    Ash is the inorganic residue from the incineration of organic matter. The amount and composition of ash in a food product depend on the nature of the food ignited and on the method of ashing.

    Ashing may also be used as the first step in preparing samples for analysis of specific minerals, by atomic spectroscopy or the various traditional methods described below. Ash contents of fresh foods rarely exceed 5%, although some processed foods can have ash contents as high as 12%, e.g., dried beef. 1.

    Application Note: Ash and Moisture Determination using

    Moisture and ash are crucial analytical values in food samples and are often needed as calculation reference for other analytical parameters too.Furthermore ashing is part of the sample preparation for the analysis of individual elements in the mineral content.Moisture is a critical parameter for shelf life time of food and ash gives information on the salt content.

    Ash (analytical chemistry) Wikipedia

    The residues after a sample is completely burnt in contrast to the ash remaining after incomplete combustion consist mostly of metal oxides. Ash is one of the components in the proximate analysis of biological materials, consisting mainly of salty, inorganic constituents. It includes metal salts which are important for processes requiring ions such as Na (Sodium), K (Potassium), and Ca (Calcium). It also includes trace minerals which are required for unique molecules, such as chlorophyll and hemoglobin.

A dried ground food sample is usually weighed into a flask containing strong acids and oxidizing agents (e.g. nitric, sulfuric acid) and then heated.

    Ash content represents the total mineral content in foods. Determining the ash content may be important for several reasons. It is a part of proximate analysis for nutritional evaluation. Ashing is the first step in preparing a food sample for specific elemental analysis. Because certain foods are high in particular minerals, ash content

    Determination of Ash Content Food Science Toolbox

    Objective: To determine the ash content of food samples. Ash content represents the inorganic residue (minerals) remaining after ignition and complete oxidation of organic matter. Dry ashing involves heating the sample in a muffle furnace at 500 600 o C. Since some elements such as Fe, Se, Pb and Hg may be partially volatized during dry ashing, wet ashing can also be done using acids or
