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.

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.

This document specifies a method for the determination of cadmium (Cd) in cereals. It is applicable to rice, brown rice, wheat and maize by graphite furnace atomic absorption spectrometry (GFAAS) after extraction with diluted nitric acid (HNO3). The limit of quantification is 0,002 mg/kg; it is approximate and dependent on the sample matrix as well as on the instrument conditions.

This document describes a method for the determination of the sum 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 (dSPE).
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.

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;

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).

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 may be improved by inclusion of an isotopically labelled internal standard, but this was not available at the time of the method validation study.

This document specifies two simplified routine methods for the determination of the amylose mass fraction of milled rice, non-parboiled. The main difference between the two methods is the dispersion procedure: method A specifies hot dispersion, and method B specifies cold dispersion.
Both methods are applicable to rice with an amylose mass fraction higher than 5 %.
NOTE These methods describe simplified procedures for the preparation of samples, which are frequently used in routine laboratories. The methods use the same reagents as the reference method (see ISO 6647-1), but omit the defatting step. Rice samples where the amylose mass fraction has been determined by the reference method are used as standards.
