Bulletin of the IDF N° 452/ 2011: Collaborative Study on Nitrate in Milk and Milk Products using a Method by Enzymatic Reduction and Photometric Determination after Griess Reaction (International Standard ISO 20541 | IDF 197)

Publication description

An alternative method for determining the content of nitrate in milk and milk products that does not involve any reagent that can have a negative effect of the environment has been developed (ISO 20541 | IDF 197) and tested in an international interlaboratory study to establish its precision (repeatability and reproducibility). This report describes the interlaboratory study and gives the results in full.

Keywords: milk, milk products, nitrate determination, interlaboratory study, precision, enzymatic reduction, photometric determination, Griess reaction.
