Bulletin of the IDF N° 411/ 2007: Selective enumeration of bifidobacteria in dairy products: Development of a standard method
Bifidobacteria play an important role as probiotic microorganisms in fermented dairy products. Usually, culture methods are used for routine examination of these products. As far as bifidobacterial enumeration is considered, several methodologies have been proposed during the last two decades, however, with limited applicability due to laborious procedures and/or lacking selectivity. According to experience, the […]
Bulletin of the IDF N° 410/ 2007: Proceedings of the 1st ParaTB Forum
Paratuberculosis is an infectious disease that has emerged to become one of the leading causes of economic loss to the dairy cattle and small ruminant industries. The first IDF ParaTB Forum held in Shanghai, China, in October 2006, provided a platform for – presentations of national /regional control or eradication programs on paratuberculosis in dairy […]
ISO 14501 | IDF 171: 2007 – Milk and milk powder – Determination of aflatoxin M1 content – Clean-up by immunoaffinity chromatography and determination by high-performance liquid
This standard has been withdrawn and replaced by the joint standard ISO 14501 | IDF 171: 2021
ISO 8070 | IDF 119: 2007 – Milk and milk products – Determination of calcium, sodium, potassium and magnesium contents – Atomic absorption spectrometric method
This standard specifies a flame atomic absorption spectrometric method for the determination of calcium, sodium, potassium and magnesium contents in milk and milk products. The method is applicable for milk and whey, buttermilk, yogurt, cream, dried milk, butter, cheese, casein and caseinate.
ISO 11868 | IDF 147: 2007 – Heat-treated milk – Determination of lactulose content – Method using high-performance liquid chromatography
This standard specifies a method for the determination of the lactulose content of heated milk, skimmed, partially skimmed or whole milk, by high-performance liquid chromatography, in order to distinguish milk sterilized by ultra-heat treatment (UHT) from in-bottle sterilized milk. The method has been tested over a lactulose content range of 200 mg/l to 1 500 […]
ISO 22160 | IDF 209: 2007 – Milk and milk-based drinks – Determination of alkaline phosphatase activity – Enzymatic photo-activated system (EPAS) method
This standard specifies a method for the determination of the alkaline phosphatase activity in pasteurized whole milk, semi-skimmed milk, skimmed milk, cream and flavoured milks using a chemiluminescent (EPAS) method. The method is applicable to milk and milk-based drinks from cows, sheep, buffalo and goats. The method is also suitable for any liquid-based sample if […]
ISO 11815 | IDF 157: 2007: Milk – Determination of total milk-clotting activity of bovine rennets
This standard describes a method for the determination of the total milk-clotting activity of bovine rennet containing only chymosin and bovine pepsin as the active coagulating enzymes on a standard milk substrate at pH 6,5. To produce accurate results with this method, check test samples of unknown origin for the absence of main milk-clotting enzymes […]
