Bulletin of the IDF N° 483/2016: Fluorimetric method for the determination of alkaline phosphatase activity in cow’s milk cheese: Interlaboratory collaborative study
This study, designed according to ISO 5725 parts 1 and 2, the protocol for interlaboratory method validation, involved a total of 17 laboratories and 8 cheese samples with ALP activities in the range of <10 mU/g to approximately 4500 mU/g. Relative Standard Deviations for repeatability and reproducibility varied by 3–6% and 8–13%, respectively. The outcome […]
Bulletin of the IDF N° 478/2015: Interlaboratory collaborative study on a flow cytometry method for lactic acid bacteria quantification in starter cultures, probiotics and fermented milk products according to ISO 19344 | IDF 232
Except for yoghurts, the repeatability limit (r) and reproducibility limit (R) values were calculated to be 0.06 and 0.45 for log10 active fluorescent units (AFU) per gram and 0.07 and 0.38 for log10 total fluorescent units (TFU) per gram. The corresponding values for yoghurts were 0.08 and 0.76 for log10 AFU per gram and 0.10 […]
Bulletin of the IDF N° 477/2014: Determination of hen’s egg white lysozyme in milk and cheese – Interlaboratory collaborative study
