ISO 23970 | IDF 252: 2021 – Milk, milk products and infant formula – Determination of melamine and cyanuric acid by liquid chromatography and tandem mass spectrometry (LC-MS/MS)
This document specifies a method for the determination of melamine and cyanuric acid with liquid chromatography in combination with tandem mass spectrometry (LC-MS/MS). The method has been validated in an interlaboratory study via the analysis of spiked samples of milk-based infant formula, soy-based infant formula, milk powder, whole milk, soy drink and milk chocolate ranging […]
ISO/TS 23758 | IDF/RM 251: 2021 – Guidelines for the validation of qualitative screening methods for the detection of residues of veterinary drugs in milk and milk products
This document describes general workflows and protocols for the validation and the verification of qualitative screening tests for the detection of residues of veterinary drugs in liquid milk (raw, pasteurized, UHT and reconstituted milk powders and whey protein extracts) including biological methods. This guideline does not cover the validation of residue analysis by HPLC, UHPLC […]
ISO 14501 | IDF 171: 2021 – Milk and milk powder – Determination of aflatoxin M1 content – Clean-up by immunoaffinity chromatography and determination by high-performance liquid chromatography
This document specifies a method for the determination of aflatoxin M1 content in milk and milk powder. The lowest level of validation is 0,08 µg/kg for whole milk powder, i.e. 0,008 µg/l for reconstituted liquid milk. The limit of detection (LOD) is 0,05 μg/kg for milk powder and 0,005 μg/kg for liquid milk. The limit […]
ISO 21187 | IDF 196: 2021 Milk – Quantitative determination of microbiological quality – Guidance for establishing and verifying a conversion relationship between results of an alternative method and anchor method results
This document gives guidelines for the establishment of a conversion relationship between the results of an alternative method and an anchor method, and its verification for the quantitative determination of the microbiological quality of milk. The conversion relationship can be used a) to convert results from an alternative method to the anchor basis or b) […]

ISO 22184 I IDF 244: 2021 – Milk and milk products – Determination of the sugar contents – High performance anion exchange chromatography with pulsed amperometric detection method (HPAEC-PAD)
This document specifies the quantitative liquid chromatographic determination of specific sugars (galactose, glucose, fructose, sucrose, lactose and maltose) in various milk and milk products, applying arabinose as an internal standard. The method is applicable to the following dairy matrices: milk, sweetened condensed milk, milk powder, cheese, whey powder, infant formula, milk dessert and yoghurt. The […]
ISO 21543 I IDF 201: 2020 – Milk and milk products – Guidelines for the application of near infrared spectrometry
This document gives guidelines for the use of near infrared (NIR) spectrometry in the analysis of milk and milk products in liquid, semi-solid or solid form. Depending on the sample form and application, different instrument setups for transmittance, diffuse reflectance or transflectance can be applied. This edition cancels and replaces the joint standard ISO 21543 […]
