Rice - Determination of amylose content - Part 2: Routine methods (ISO 6647-2:2007)

ISO 6647-2:2007 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 in the dispersion procedure: method A specifies hot, and method B cold, dispersion.
Both methods are applicable to rice with amylose mass fraction higher than 5 %.

Reis - Bestimmung des Amylosegehalts - Teil 2: Routineverfahren (ISO 6647-2:2007)

Dieser Teil der ISO 6647 legt zwei vereinfachte Routineverfahren für die Bestimmung des Massenanteils an Amylose von gemahlenem Reis fest, bei dem es sich nicht um Parboiled Reis handelt. Der Hauptunterschied zwischen den beiden Verfahren besteht in der Art der Dispergierung. Verfahren A legt eine Verfahrensweise zur Heißdispergierung und Verfahren B eine Verfahrensweise zur Kaltdispergierung fest.
Beide Verfahren sind auf Reis mit einem Massenanteil an Amylose von mehr als 5 % anwendbar.
ANMERKUNG   Diese Verfahren beschreiben vereinfachte Verfahrensweisen für die Herstellung von Proben, wie sie häufig in Laboratorien verwendet werden, die Routineverfahren anwenden. Bei den Verfahren kommen die gleichen Reagenzien wie beim Referenzverfahren (siehe ISO 6647 1) zum Einsatz, jedoch entfällt der Entfettungsschritt. Als Standards werden Reisproben verwendet, deren Massenanteil an Amylose mithilfe des Referenzverfahrens bestimmt wurde.

Riz - Détermination de la teneur en amylose - Partie 2: Méthodes de routine (ISO 6647-2:2007)

L'ISO 6647-2:2007 indique deux méthodes de routine simplifiées pour la détermination de la teneur (fraction massique) en amylose du riz usiné, non étuvé. La différence principale entre ces deux méthodes est la méthode de dispersion. La méthode A indique une procédure de dispersion à chaud tandis que la méthode B fonctionne à froid.
Ces deux méthodes s'appliquent au riz possédant une teneur en amylose supérieure à 5 % (fraction massique).
