The fifth constituent, carbohydrates, are calculated based on the determination of the four others. Proximates should nearly always account for 100% of a food product; any deviation from 100% displays the resolution of the chemical test, as small variations in the way each test is performed accumulate or overlap the compositional make-up.
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 2+ (calcium).
Example conversion factors, known as N factors, for foods range from 6.38 for dairy and 6.25 for meat, eggs, maize (corn) and sorghum to 5.83 for most grains; 5.95 for rice, 5.70 for wheat flour, and 5.46 for peanuts. [7] In practice, 6.25 is used for almost all food and feed regardless of applicability.
