Food moisture analysis is the determination of the concentration of water in a food sample. A variety of techniques may be used including Karl Fischer titration and loss on drying. Many technical standards exist which define test methods for determining moisture in different types of food.
It was founded in 1884 as the Association of Official Agricultural Chemists (AOAC) and became AOAC International in 1991. It publishes standardized, chemical analysis methods designed to increase confidence in the results of chemical and microbiological analyses. Government agencies and civil organizations often require that laboratories use ...
In industry, the standard proximates are: [2] [3] [4] Moisture content; Volatile matter; Ash content; Fixed carbon; Carbohydrates (calculated) Analytically, four of the five constituents are obtained via chemical reactions and experiments. The fifth constituent, carbohydrates, are calculated based on the determination of the four others.
protein by analysis of total nitrogen, either by Dumas or Kjeldahl methods; total fat, traditionally by a solvent extraction, but often now by secondary methods such as NMR; crude ash (total inorganic matter) by combustion at 550 °C; estimated dietary fibre by various AOAC methods such as 985.29
The current average interest rate for a 30-year fixed mortgage is 7.04% for purchase and 7.07% for refinance, unchanged from 7.04% for purchase and up 5 basis points from 7.02% for refinance last ...
The SNIF-NMR method has been adopted by the International Organisation of Vine and Wine (OIV) and the European Union as an official method for wine analysis. It is also an official method adopted by the Association Of Analytical Chemists (AOAC) for analysis of fruit juices, maple syrup, vanillin, and by the European Committee for ...

A crucible and tongs, on a green mat. The ash content of a sample is a measure of the amount of inorganic noncombustible material it contains. The residues after a sample is completely burnt - in contrast to the ash remaining after incomplete combustion - typically consist of oxides of the inorganic elements present in the original sample.
