Bulletin of the IDF N° 468/2013: Interlaboratory collaborative study of a method for the determination of nitrogenous fractions in cheese-ISO 27871 | IDF224

Publication description

Results of an international collaborative study conducted to establish precision figures for the determination of nitrogenous fractions in cheese. Six samples (2 soft cheeses, 3 semi-hard and hard cheeses, and 1 processed cheese) were supplied to the laboratories participating in the study.

The laboratories were located in 8 different countries. The method used by all laboratories was that described in International Standard ISO 27871|IDF 224. The statistical analysis of the results was carried out in accordance with ISO 5725-1/2.
