Maize - Determination of moisture content (on milled grains and on whole grains) (ISO 6540:2021)

Maize - Determination of moisture content (on milled grains and on whole grains) (ISO 6540:2021)

This document specifies two methods:
— a reference method for the determination of the moisture content of maize grains and ground whole
maize, groats, grits and maize flour, see Clause 4;
— a routine method for the evaluation of the moisture content of maize in whole grains, see Clause 5.
The latter is not suitable for use for experts’ reports, or for calibration or checking of humidity meters,
because of its significant bias to the reference method (see Table B.3).

Mais - Bestimmung des Feuchtegehalts (von gemahlenen und ganzen Körnern) (ISO 6540:2021)

Dieses Dokument legt zwei Verfahren fest:
- ein Referenzverfahren zur Bestimmung des Feuchtegehalts von ganzen Maiskörnern und gemahlenem Vollmais, Grobgrieß, Feingrieß und Maismehl, siehe Abschnitt 4;
- ein Routineverfahren zur Bewertung des Feuchtegehalts von ganzen Maiskörnern, siehe Abschnitt 5.
Das letztgenannte Verfahren ist wegen seiner signifikanten systematischen Abweichungskomponente gegenüber dem Referenzverfahren (siehe Tabelle B.3) nicht zur Anwendung für Fachberichte oder für die Kalibrierung oder Überprüfung von Feuchtemessgeräten geeignet.

Maïs - Détermination de la teneur en eau (sur grains broyés et sur grains entiers) (ISO 6540:2021)

Le présent document spécifie deux méthodes:
- une méthode de référence pour la détermination de la teneur en eau des grains de maïs et de la mouture de maïs entier, des gruaux et de la farine de maïs; voir l'Article 4;
- une méthode pratique pour l'évaluation de la teneur en eau des grains de maïs, en opérant sur les grains entiers; voir l'Article 5.
Cette dernière ne convient ni pour des expertises ni pour l'étalonnage ou le contrôle des humidimètres en raison de son biais important par rapport à la méthode de référence (voir le Tableau B.3).

EN ISO 27971:2023

This document specifies a method of determining, using an Alveograph, the rheological properties of different types of dough obtained from common wheat flour (Triticum aestivum L.) produced by industrial milling or laboratory milling.
It describes the Alveograph test and how to use a laboratory mill to produce flour in two stages:
—    stage 1: preparation of the wheat grain for milling to make it easier to separate the bran from the endosperm;
—    stage 2: the milling process, including breaking between three fluted rollers, reduction of particle size between two smooth rollers and the use of a centrifugal sieving machine to grade the products.

Foodstuffs - Determination of T-2 toxin and HT-2 toxin in cereals and cereal products for infants and young children by SPE clean up and HPLC-MS/MS
EN 16923:2022

This document describes a method for the determination of T-2 toxin and HT-2 toxin in cereals and cereal-based products, e.g. oats, intended for nutrition of infants and young children by high performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS/MS) after cleanup by solid phase extraction (SPE) [5].
The method has been validated for HT-2 toxin in oat flour at levels of 9,3 µg/kg and 28,1 µg/kg, oat flakes at levels of 16,5 µg/kg and 21,4 µg/kg, and breakfast cereals (containing oat flakes) at a level of 8,1 µg/kg and for T-2 toxin in oat flour at levels of 4,4 µg/kg and 8,3 µg/kg, oat flakes at levels of 4,9 µg/kg and 6,6 µg/kg and breakfast cereals (containing oat flakes) at a level of 3,5 µg/kg.
Laboratory experiences [6] have shown that the method is also applicable to highly swelling materials (dry cereal based porridges and modified starches), but these were not examined in the method validation study. Details are outlined in 7.3.
The method can also be applied to oat-by-products at higher levels of T-2- and HT-2 toxin. In this case, the dilution steps need to be considered [6].
The method can also be applied to cereals and cereal products for infants and young children based on e.g. wheat, barley and rice. In this case, the method needs to be in-house-validated for each material. At the time of the interlaboratory study, planned range was 10 µg/kg to 100 µg/kg, and it is known from the pre-study that the method works well in the whole range, although final validation was only done in the range from 3,5 µg/kg to 28,1 µg/kg.

Foodstuffs - Determination of ergot alkaloids in cereals and cereal products by dSPE clean-up and LC-MS/MS
EN 17425:2021

This document describes a method for the determination of the sum total of six ergot alkaloids (ergocornine, ergometrine, ergocristine, ergotamine, ergosine and ergocryptine) and their  inine epimer pairs by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) after clean-up by dispersive solid phase extraction (SPE).
The method has been validated for cereals and cereal-based food products.
The method has been validated in the range 13,2 µg/kg to 168 µg/kg for the sum of the twelve ergot alkaloids, in rye flour, rye bread and cereal products (breakfast cereal, infant breakfast cereal, and crispbread) that contained rye as an ingredient, as well as seeded wholemeal flour and a barley and rye flour mixture.
Method performance was satisfactory in the range 24,1 µg/kg to 168 µg/kg, however at lower concentrations RSDR values were greater than 44 %, and HorRat values exceeded 2,0, indicating the method may not be fully suitable at concentrations below 24 µg/kg for sum of ergot alkaloids, although it is suitable for screening at these concentrations. Method performance may be improved by inclusion of an isotopically labelled internal standard, but this was not available at the time of the method validation study.
