Rice - Determination of amylose content - Part 2: Routine methods (ISO 6647-2:2015)

This part of ISO 6647 specifies a simplified routine method for the determination of the amylose
content of milled, non-parboiled rice in the range from 1 % to 30 %. Rice samples for which the amylose
content has been determined by the reference method size exclusion chromatography (SEC) are used as
standards to generate the calibration curve.
NOTE The use of standards calibrated by SEC is an approach to determine the true amylose content and
decreases the conversion errors of this part of ISO 6647.[1]

Riz - Détermination de la teneur en amylose - Partie 2: Méthodes de routine (ISO 6647-2:2015)

L'ISO 6647-2:2015 spécifie une méthode de routine simplifiée pour la détermination de la teneur en amylose du riz usiné et non étuvé, dans une plage allant de 1 % à 30 %. Les échantillons de riz dont la teneur en amylose a été déterminée à l'aide de la méthode de référence (par chromatographie par exclusion stérique) sont utilisés comme étalons pour tracer la courbe d'étalonnage.

Riž - Določevanje amiloze - 2. del: Rutinske metode (ISO 6647-2:2015)

Ta del standarda ISO 6647 določa poenostavljeno rutinsko metodo za določanje vsebnosti amiloze v brušenem, predkuhanem rižu v obsegu vsebnosti amiloze 1–30 %. Vzorci riža, pri katerih je bila vsebnost riža določena z referenčno metodo kromatografije z ločevanjem po velikosti (SEC), se uporabljajo kot standardi za pripravo kalibracijske krivulje.
OPOMBA Uporaba standardov, kalibriranih s SEC, je pristop za določanje prave vsebnosti amiloze, ki zmanjša napake pri pretvorbi v tem delu standarda ISO 6647.[1].
