Milk, milk products, infant formula and adult nutritionals - Determination of minerals and trace elements - Inductively coupled plasma mass spectrometry (ICP-MS) method (ISO 21424:2018)

Milk, milk products, infant formula and adult nutritionals - Determination of minerals and trace elements - Inductively coupled plasma mass spectrometry (ICP-MS) method (ISO 21424:2018)

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 infant formula and adult nutritional products. The method is also applicable for milk, milk powder, whey powder, butter and cheese excluding the determination of Cr, because all Cr results were below the quantification limit and reproducibility could not be determined in these matrices[1]. The present method is an extension of ISO 20649 | IDF 235 (AOAC 2011.19[2]) which was validated only for Cr, Mo and Se in infant formula and adult nutritional products.

Milch, Milcherzeugnisse, Säuglingsnahrung und Nahrungsergänzungsmittel für Erwachsene - Bestimmung von Mineralien und Spurenelementen - Verfahren mit induktiv gekoppelter Plasma-Massenspektrometrie (ICP-MS) (ISO 21424:2018)

Dieses Dokument legt ein Verfahren für die quantitative Bestimmung von Calcium (Ca), Kupfer (Cu), Eisen (Fe), Magnesium (Mg), Mangan (Mn), Phosphor (P), Kalium (K), Natrium (Na), Zink (Zn), Chrom (Cr), Molybdän (Mo) und Selen (Se) mittels Massenspektrometrie mit induktiv gekoppeltem Plasma (ICP MS) fest.
Das Verfahren ist für die Bestimmung aller 12 Elemente in Säuglingsnahrung und Nahrungs-ergänzungsmitteln für Erwachsene anwendbar. Das Verfahren ist auch für Milch, Milchpulver, Molkepulver, Butter und Käse anwendbar, allerdings mit Ausnahme der Bestimmung von Cr, weil sämtliche Cr Ergebnisse unterhalb der Quantifizierungsgrenze lagen und die Vergleichpräzision in diesen Matrices nicht bestimmt werden konnte [1]. Bei dem vorliegenden Verfahren handelt es sich um eine Erweiterung von ISO 20649 | IDF 235 (AOAC 2011.19 [2]), die nur für Cr, Mo und Se in Säuglingsnahrung und Nahrungsergänzungsmitteln für Erwachsene validiert wurde.
Die in Tabelle 1 angegebenen Bereiche werden abgedeckt (siehe auch Tabelle A.1).

Lait, produits laitiers, formules infantiles et produits nutritionnels pour adultes - Détermination de la teneur en minéraux et en oligo-éléments - Méthode par spectrométrie de masse avec plasma à couplage inductif (ICP-SM) (ISO 21424:2018)

Le présent document spécifie une méthode de détermination quantitative de la teneur en calcium (Ca), cuivre (Cu), fer (Fe), magnésium (Mg), manganèse (Mn), phosphore (P), potassium (K), sodium (Na), zinc (Zn), chrome (Cr), molybdène (Mo) et sélénium (Se) par spectrométrie de masse avec plasma à couplage inductif (ICP-SM).
La méthode est applicable pour la détermination de la totalité des 12 éléments dans les formules infantiles et les produits nutritionnels pour adultes. La méthode est également applicable au lait, au lait en poudre, au lactosérum en poudre, au beurre et au fromage, à l'exclusion de la détermination du Cr, car tous les résultats de Cr étaient inférieurs à la limite de quantification et la reproductibilité n'a pas pu être établie dans ces matrices.[1] La présente méthode est une extension de l'ISO 20649 | FIL 235 (AOAC 2011.19[2]) qui n'a été validée que pour le Cr, le Mo et le Se dans les formules infantiles et les produits nutritionnels pour adultes.

Milk, milk products, infant formula and adult nutritionals - Determination of fatty acids composition - Capillary gas chromatographic method (ISO 16958:2015)
SIST EN ISO 16958:2020

ISO 16958:2015 specifies a method for the quantification of individual and/or all fatty acids in the profile of milk, milk products, infant formula and adult nutritional formula, containing milk fat and/or vegetable oils, supplemented or not supplemented with oils rich in long chain polyunsaturated fatty acids (LC-PUFA). This also includes groups of fatty acids often labelled [i.e. trans fatty acids (TFA), saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, omega-6 and omega-9 fatty acids] and/or individual fatty acids [i.e. linoleic acid (LA), α-linolenic acid (ALA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)].
The determination is performed by direct transesterification in food matrices, without prior fat extraction, and consequently it is applicable to liquid samples or reconstituted powder samples with water having total fat ≥ 1,5 % m/m.
The fat extracted from products containing less than 1,5 % m/m fat can be analysed with the same method after a preliminary fat extraction using methods referenced in Clause 2. Dairy products, like soft or hard cheeses with acidity level ≤ 1 mmol/100 g of fat, can be analysed after a preliminary fat extraction using methods referenced in Clause 2. For products supplemented or enriched with PUFA with fish oil or algae origins, the evaporation of solvents should be performed at the lowest possible temperature (e.g. max. 40 °C) to recover these sensitive fatty acids.

Milk and milk products - Determination of milk fat purity by gas chromatographic analysis of triglycerides (ISO 17678:2019)
SIST EN ISO 17678:2019

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 is achieved by using the defined triglyceride formulae based on the normalized weighted sum of individual triglyceride peaks which are sensitive to the integrity of the milk[6][7]. The integrity of the milk fat can be determined by comparing the result of these formulae with those previously observed for a range of pure milk fat samples[12]. Both vegetable fats and animal fats such as beef tallow and lard can be detected.
The method is applicable to bulk milk, or products made thereof, irrespective of the variation in common feeding practices, 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.
Because a false-positive result can occur, the method does not apply to milk fat related to these circumstances:
a)    obtained from bovine milk other than cow's milk;
b)    obtained from single cows;
c)    obtained from cows whose diet contained a particularly high proportion of vegetable oils such as rapeseed, cotton or palm oil, etc.;
d)    obtained from cows suffering from serious underfeeding (strong energy deficit);
e)    obtained from colostrum;
f)     subjected to technological treatment such as removal of cholesterol or fractionation;
g)    obtained from skim milk, buttermilk or whey;
h)    obtained from cheeses showing increased lipolysis;
i)     extracted 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 i), substantial quantities of partial glycerides or phospholipids can pass into the fat phase.
NOTE 1    In nature, butyric (n-butanoic) acid (C4) occurs exclusively in milk fat and enables quantitative estimations of low to moderate amounts of milk fat in vegetable and animal fats to be made. Due to the large variation of C4, for which the approximate content ranges from 3,1 % fat mass fraction to 3,8 % fat mass fraction, it is difficult to provide qualitative and quantitative information for foreign fat to pure milk fat ratios of up to 20 % mass fraction[11].
NOTE 2    In practice, quantitative results cannot be derived from the sterol content of vegetable fats, because they depend on production and processing conditions. Furthermore, the qualitative determination of foreign fat using sterols is ambiguous.
NOTE 3    Due to special feeding practices such as those related to c) and d), false-positive results have sometimes been reported for milk from certain Asian regions[15]. Moreover, grass-only diets such as mountain and, in particular, highland pasture feeding sometimes cause false-positive results, which can be substantiated by a content of conjugated linoleic acid (C18:2 c9t11) of ≥ 1,3 % fatty acid mass fraction[16][17]. Nevertheless, results conforming to the criteria of milk fat purity specified in this document are accepted, even if samples were undoubtedly produced under conditions reported in this note, including those described in h).
