Rice - Determination of amylose content - Part 1: Spectrophotometric method with a defatting procedure by methanol and with calibration solutions of potato amylose and waxy rice amylopectin (ISO 6647-1:2020)

This document specifies a reference method for the determination of the amylose content of milled rice, non-parboiled. The method is applicable to rice with an amylose mass fraction higher than 5 %.
This document can also be used for husked rice, maize, millet and other cereals if the extension of this scope has been validated by the user.
NOTE    Amylose values determined with this document can be compared with PDO and PGI legislation.

Reis - Bestimmung des Amylosegehalts - Teil 1: Spektrophotometrisches Verfahren mit Entfettungsverfahren durch Methanol und mit Kalibrierlösungen von Kartoffelamylose und wachsartigem Reisamylopektin (ISO 6647 1:2020)

Dieses Dokument legt ein Referenzverfahren für die Bestimmung des Amylosegehalts von gemahlenem Nicht-Parboiled-Reis fest. Das Verfahren ist anwendbar auf Reis mit einem Amylose-Massenanteil von mehr als 5 %.
Dieses Dokument kann auch für geschälten Reis, Mais, Hirse und andere Getreidearten angewendet werden, wenn die Erweiterung dieses Anwendungsbereichs von dem Anwender überprüft wurde.
ANMERKUNG Mit diesem Dokument bestimmte Amylose-Werte können mit den Rechtsvorschriften der geschützten Ursprungsbezeichnung (g. U., en: Protected Designation of Origin, PDO) und der geschützten geografischen Angabe (g. g. A., en: Protected Geographical Indication, PGI) verglichen werden.

Riz - Détermination de la teneur en amylose - Partie 1: Méthode spectrophotométrique avec un mode opératoire de dégraissage au méthanol et des solutions d'étalonnage d'amylose de pomme de terre et d'amylopectine de riz gluant (ISO 6647-1:2020)

Le présent document spécifie une méthode de référence pour la détermination de la teneur en amylose du riz usiné, non étuvé. La méthode est applicable à du riz avec une fraction massique d'amylose supérieure à 5 %.
Le présent document peut aussi être utilisé pour le riz décortiqué, le maïs, le millet et d'autres céréales si l'extension de son domaine d'application a été validée par l'utilisateur.
NOTE    Les valeurs de teneur en amylose déterminées selon le présent document peuvent être comparées à la législation AOP et IGP.
