ISO 11868|IDF 147:2007 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 mg/l and is applicable to all heat-treated milks. The method described is to be used in cases of dispute.

ISO 23065:2009 specifies a method for the determination of the omega-3 and omega-6 fatty acid content in anhydrous milk fat extracted from dairy products supplemented or naturally enriched with these constituents. The specified procedure allows the evaluation of the most important omega-3 and omega-6 fatty acids.

ISO 3356|IDF 63:2009 specifies a method for the determination of alkaline phosphatase activity in milk. The method applies to alkaline phosphatase activities not less than 1 µg of phenol per millilitre. The method is also suitable for the determination of alkaline phosphatase activity in milk powder, buttermilk and buttermilk powder, whey and whey powder.

ISO/TS 27265|IDF/RM 228:2009 specifies a method for the enumeration of colony-forming units (CFU) of specially thermoresistant spores of thermophilic bacteria in dried milk products by using a colony-count technique at 55 °C after heating the sample at 106 °C. The applicability of ISO/TS 27265|IDF/RM 228:2009 is limited to dried whole milk, skim milk, and buttermilk products that are destined to be recombined and used in the manufacture of sterilized (e.g. UHT or retort-treated) milk products.

Milk - Determination of fat content - Gravimetric method (Reference method) (ISO 1211:2010)
This International Standard specifies a reference method for the determination of milk fat purity using gas chromatographic analysis of triglycerides. Both vegetable fats and animal fats such as beef tallow and lard can be detected. By using defined triglyceride equations, the integrity of milk fat is determined. Basically, the method applies to bulk milk, or products made thereof, irrespective of feeding, breed or lactation conditions. In particular, the method is applicable to fat extracted from milk products purporting to contain pure milk fat with unchanged composition, such as butter, cream, milk, and milk powder. However, under the circumstances listed hereafter, a false positive result can be obtained. Hence, the method is not applicable to milk fat: a) obtained from bovine milk other than cow's milk; b) obtained from single cows; c) obtained from cows which received an exceptionally high feeding of pure vegetable oils such as rapeseed oil; d) obtained from colostrum; e) subjected to technological treatment such as removal of cholesterol or fractionation; f) obtained from skim milk or buttermilk; g) extracted by using the Gerber, Weibull–Berntrop or Schmid–Bondzynski–Ratzlaff methods, or that has been isolated using detergents (e.g. the Bureau of Dairy Industries method). With the extraction methods specified in g), substantial quantities of partial glycerides or phospholipids can pass into the fat phase. Consequently, the scope of this International Standard excludes certain products and particularly cheese, whose ripening process can also affect the fat composition to such a degree that a false positive result is obtained.

Dried milk - Determination of titratable acidity (Reference method) (ISO 6091:2010, identical)
This International Standard specifies the reference method for the determination of the fat content of milk of good physicochemical quality.The method is applicable to raw cow milk, raw sheep milk, raw goat milk, reduced fat milk, skimmed milk, chemically preserved milk, and processed liquid milk.It is not applicable when greater accuracy is required for skimmed milk, e.g. to establish the operatingefficiency of cream separators.NOTE ISO 7208 specifies a special method for skimmed milk products.
