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

ISO 6647-2:2015 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.

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].
