ISO 22186 I IDF 245: 2020 Milk and milk products – Determination of nitrofurazone
This document specifies a liquid chromatography tandem mass spectrometry (LC–MS/MS) method for the quantification of the inhibitory substance, nitrofurazone, in milk and milk products. The method has been validated for measuring trace levels of intact nitrofurazone to levels down to 1 ng/g in fluid milk and powdered dairy products on a whole product (i.e. powder) […]
ISO 22579 I IDF 241: 2020 – Infant formula and adult nutritionals – Determination of fructans – High performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD) after enzymatic treatment
This document specifies a method for the determination of inulin-type fructans (including oligofructose, fructooligosaccharides) in infant formula and adult nutritionals (both powder and liquid) containing 0,03 g/100 g to 5,0 g/100 g of fructans in the product as prepared ready for consumption. The method has been validated in a multi laboratory study[1] with reconstituted standard […]
Bulletin of the IDF N° 504/2020: New applications of MIR spectrometry: Quality assurance practices with new parameters in raw milk analysis
Traditionally applied for quantitative determination of major components of milk, MIR Filter apparatus techniques have been used for a long time. Recently, Fourier-transform infrared spectroscopy (FTIR) collects high-spectral-resolution data over a wide spectral range. Thanks to additional prediction models developed by researchers and instrument manufacturers, FT-IR spectra can be used beyond quantitative determination of major […]
ISO 23293 | IDF 247:2020 – Milk-based infant formula powders – Quantification of whey protein content by sodium dodecyl sulfate-capillary gel electrophoresis (SDS-CGE)
This document specifies a method for the determination of the whey to casein protein ratio, ranging from 20:80 to 80:20 in cow milk-based infant formula powders. This method does not apply to the analysis of infant formulas containing hydrolysed protein or proteins from other sources (e.g. plants or milk from other mammals).
ISO 23291 I IDF 248: 2020 – Milk and milk products – Guidelines for the application of in-line and on-line infrared spectrometry
This document gives guidelines for using infrared spectrometry in in-line and on-line applications for dairy processing. These applications are distinct to those covered in ISO 21543 | IDF 201. It is applicable, but not limited, to: — the determination of protein, fat and total solids in liquid milk and milk products using mid and near […]
ISO 16297 I IDF 161: 2020 – Milk – Bacterial count – Protocol for the evaluation of alternative methods
This document specifies a protocol for the evaluation of instrumental alternative methods for total bacterial count in raw milk from animals of different species. NOTE The document is complementary to ISO 16140-2 and ISO 8196 | IDF 128 (all parts). Standard only available in English
ISO 17678 I IDF 202: 2019 – Milk and milk products – Determination of milk fat purity by gas chromatographic analysis of triglycerides
This document specifies a reference method for the determination of milk fat purity using gas chromatographic analysis of triglycerides. The method utilizes the differences in triglyceride fingerprint of milk fat from the individual triglyceride fingerprints of other fats and oils to determine samples which are outside the range normally observed for milk fat. This edition […]
ISO 15151 I IDF 229: 2018 – Milk, milk products, infant formula and adult nutritionals — Determination of minerals and trace elements – Inductively coupled plasma atomic emission spectrometry (ICP-AES) method
This document specifies a method for the quantitative determination of calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), phosphorus (P), potassium (K), sodium (Na) and zinc (Zn) using inductively coupled plasma atomic emission spectrometry (ICP-AES). The method is applicable for milk, dried milk, butter, cheese, whey, dried whey, infant formula and adult nutritional […]
ISO 21424 I IDF 243: 2018 – Milk, milk products, infant formula and adult nutritionals – Determination of minerals and trace elements — Inductively coupled plasma mass spectrometry (ICP-MS) method
This document specifies a method for the quantitative determination of calcium (Ca), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), phosphorus (P), potassium (K), sodium (Na), zinc (Zn), chromium (Cr), molybdenum (Mo) and selenium (Se) using inductively coupled plasma and mass spectrometry (ICP-MS). The method is applicable for the determination of all 12 elements in […]
ISO 21422 | IDF 242: 2018 – Milk, milk products, infant formula and adult nutritionals – Determination of chloride – Potentiometric titration method
This document specifies a method for the determination of chloride in milk, milk products, infant formula and adult nutritionals by potentiometry with an analytical range of 0,35 mg chloride/100 g to 711,6 mg chloride/100 g product, or ready-to-feed products.
