La présente Norme Internationale donne des lignes directrices relatives aux méthodes d'échantillonnage du lait et des produits laitiers destinés à une analyse microbiologique, chimique, physique et sensorielle, sauf pour l'échantillonnage (semi) automatisé.
This International Standard specifies a reference method for the determination of the freezing point of rawbovine milk, heat-treated whole, reduced fat and skimmed bovine milk, as well as raw ovine and caprine milk,by using a thermistor cryoscope.The freezing point can be used to estimate the proportion of extraneous water in milk. Calculation of theamount of extraneous water is subject to daily and seasonal variations, and is not within the scope of thisInternationar Standard.Results obtained from samples with a titratable acidity exceeding 20 ml of 0.1 mol/l sodium hydroxide solutionper 10 g of non-fat solids are not representative of the original milk.NOTE 1 Sterilization and vacuum pasteurization can affect the freezing point of milk (see Reference [5]).NOTE 2 The method uses plateau-timed instruments. For routine measurements, other thermistor cryoscope methods,i.e. fixed time procedures, can be used. Guidelines for the application of other procedures are given in Annex C.NOTE 3 The limit value mentioned for the titratable acidity in Clause 1 and 9.2 applies to bovine milk. It is possible thatthe limit values for ovine and caprine milk are higher.
This International Standard specifies a method for the determination of the nitrogen content and crude protein calculation of milk and milk products by the Kjeldahl principle, using traditional and block digestion methods. The methods are applicable to liquid, cow's (whole, partially skimmed or skimmed milk), goat's and sheep's whole milk, hard, semi-hard and processed cheese, dried milk, and dried milk products, including milk-based infant formulae, milk protein concentrate, whey protein concentrate, casein and caseinate. The methods are not applicable to samples containing ammonium caseinate. Inaccurate crude protein results will be obtained if non-milk sources of nitrogen are present in the products in this International Standard.
This standard gives guidelines for the quantitative compositional analysis of milk and liquid milk products, such as raw milk, processed milk, cream and whey, by measurement of the absorption of mid-infrared radiation. The guidelines specified are applicable to the analysis of cow´s milk. The guidelines are also applicable to the analysis of milk of other species (goat, ewe, buffalo, etc.) and derived liquid milk products, provided adequate calibrations are generated for each application and adequate control procedures are in place.
