The Dumas technique has been automated and instrumentalized, so that it is capable of rapidly measuring the crude protein concentration of food samples. This automatic Dumas technique has replaced the Kjeldahl method as the standard method of analysis for nutritional labelling of protein content of foods (except in high fat content foods where ...
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.
The molybdovanadate reagent is a solution containing both the molybdate and vanadate ions. It is commonly used in the determination of phosphate ion content. [1] [2] The reagent used is ammonium molybdovanadate with the addition of 70% perchloric acid (sulfuric acid is also known to be used).
Traditionally, food companies would send food samples to laboratories for physical testing. Typical analyses include: moisture (water) by loss of mass at 102 °C; 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
The nitrogen solubility index (NSI) is a measure of the solubility of the protein in a substance. It is typically used as a quick measure of the functionality of a protein, for example to predict the ability of the protein to stabilise foams, emulsions or gels.
Parle Products is an Indian multinational food corporation, which makes biscuits and confectionery products. It is best known for the biscuit brand Parle-G , [ 2 ] [ 3 ] which is the best-selling biscuit brand in the world, according to a 2011 Nielsen report.
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.
