Bulletin of the IDF N° 440/ 2009: Interlaboratory Collaborative Study on the Kjeldahl Reference Method for Nitrogen Determination in Sheep and Goat Milk according to ISO 8968-1/2 | IDF 20-1/2
The reference method for determination of nitrogen in milk (International Standard ISO 8968-1/2|IDF 20-1/2) was subjected to an international interlaboratory study to establish its precision characteristics (reproduci-bility, R, and repeatability, r) when the method is applied to sheep milk and goat milk. This paper is the report of the interlaboratory studies. Keywords: sheep milk, goat […]
Bulletin of the IDF N° 439/ 2009: Interlaboratory Collaborative Studies on Reference Method ISO 1211 | IDF 1 for the Determination of the Fat Content in Cow Milk, Sheep Milk and Goat Milk
The gravimetric reference method for determination of fat in milk (International Standard ISO 1211| IDF 1) was subjected to new international interlaboratory studies to establish its precision characteristics (reproducibility, R, and repeatability, r). In these new studies the method was applied to cow whole milk, cow reduced fat milk and cow skimmed milk and to […]
Bulletin of the IDF N° 437/ 2009: Effects of Foot-and-Mouth Disease on the Dairy Industry
Position paper outlining the effects that an outbreak of Foot-and-Mouth Disease, a highly infectious viral disease of cloven hoofed livestock, can have on the dairy industry in any country in the world. In some countries the dairy industries are complex and integrated, as most of the milk or milk products produced are destined for international […]
Bulletin of the IDF N° 435/ 2009: Standardization of a Chemiluminescent Method to Detect Alkaline Phosphatase in Liquid Dairy Products
Collaborative studies for the IDF/ISO standard: ISO 22160|IDF 209:2007 – Milk and milk-based drinks – Determination of alkaline phosphatase activity – Enzymatic photo-activated system (EPAS) method. Keywords: Alkaline phosphatase, Enzyme, EPAS, Milk, Milk drinks, Precision, Standard
Bulletin of the IDF N° 434/2009: International Collaborative Study on the Gas-Liquid Chromatographic Method for the Determination of Milk Fat Purity in Milk and Milk Products by Analysis of Triglycerides – Draft international standard ISO 17678 | IDF 202
International Collaborative Study Adulteration with cheaper fats of milkfat naturally present in pure milk products is not a new problem but the methods of analysis available to detect adulteration and determine its extent have only been sufficiently sensitive to carry out the task satisfactorily relatively recently. A new draft International standard has been produced by […]

Proceedings of the IDF/FAO Symposium “A Revolution in Food Safety Management – Practical implementation in the dairy product chain”, Bali (ID), 13-15 February 2008. Papers are related to charting a new course in food safety with the development and implementation of risk-based metrics; incorporating risk-based metrics in HACCP plans; getting to grips with pathogens; practices, […]
Bulletin of the IDF N° 431/ 2008: Dioxin and PCB levels in milk
A document based on replies to IDF questionnaire 3002/SCRCC – Dioxin/PCB levels in milk. Since the health concerns peaks of the late 90’s, the dioxin and related compounds issue has evolved in most of the developed countries. Due to its rapid transfer to the food chain, the key to reduce human exposure to PCDDs/PCDFs is […]
Bulletin of the IDF N° 430/ 2008: Hygiene and Food Safety of Dairy products and Food Standards for International Trade
Proceedings of the Conference on Hygiene and Food Safety of Dairy Products and Food Standards for International Trade, at the IDF World Dairy Congress in Shanghai (CN), October 2006. The publication contains the conference papers covering : Recent Developments in Risk Management, introducing the new approach to quantitative risk management; Practical Food Safety Management, providing […]
Bulletin of the IDF N° 428/ 2008: Determination of omega-3 and omega-6 fatty acid content by gas-liquid chromatography in milk fat from Enriched products – Interlaboratory collaborative studies
Omega-3 and omega-6 fatty acids have been shown to lower the risk of coronary heart disease. As a result, milk and different dairy products, including infant formula, supplemented with or naturally enriched in omega-3 fatty acids, are now available on the market. A reliable method to evaluate the real content of these nutrients has been […]
Bulletin of the IDF N° 427/2008: Towards A Reference System For Somatic Cell Counting In Milk
Somatic cell count is a main indicator of udder health in lactating animals. The direct microscopic method (DMSCC) is the reference method, and offically recognized as such for the calibration of automated somatic cell counting equipment. The first paper, the interlaboratory collaborative study, has established the precision (repeatability, r, and reproducibility, R) of the reference […]
