Cereals and cereal products - Common wheat (Triticum aestivum L.) - Determination of alveograph properties of dough at adapted hydration from commercial or test flours and test milling methodology

This document specifies a method that uses an alveograph to determine the rheological properties of different types of dough at adapted hydration obtained from “soft” to “hard” wheat flour (Triticum aestivum L.) produced by industrial milling or laboratory test 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 (see Clause 7);
    Stage 2: the milling process itself, including the break system involving three fluted rollers, reduction of particle size between two smooth rollers and the use of a centrifugal sieving machine to grade the products (see Clause 8).

Getreide und Getreideerzeugnisse - Weizen (Triticum aestivum L.) - Bestimmung der Eigenschaften von Teig bei adaptierter Flüssigkeitszufuhr zu handelsüblichen Mehlen oder Versuchsmehlen bei gleichen Versuchsmahlverfahren mittels Alveograph

Céréales et produits céréaliers - Blé tendre (Triticum aestivum L.) - Détermination des propriétés alvéographiques d’une pâte à hydratation constante adaptée de farine industrielle ou d’essai et méthodologie pour la mouture d’essai

Le présent document prescrit une méthode de détermination, au moyen de l'alvéographe, des
caractéristiques rhéologiques de différents types de pâtes à hydratation adaptée obtenues à partir de farines
de blés tendres (Triticum aestivum L.) « soft » à « hard » issues de mouture industrielle ou de mouture d’essai
en laboratoire.
Il décrit l’essai à l’alvéographe et les conditions d’obtention de la farine au moyen d’un moulin de laboratoire
en deux étapes :
⎯ étape 1 : préparation des grains de blé en vue de la mouture, afin de faciliter la séparation du son et de
l’amande (voir Article 7) ;
⎯ étape 2 : processus de mouture comprenant un broyage entre trois cylindres cannelés, une réduction de
la taille des particules entre deux cylindres lisses et le classement des produits à l’aide d’une bluterie
centrifuge (voir l’Article 8).

This Technical Specification (CEN/TS) was approved by CEN on 9 March 2008 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
