Animal and vegetable fats and oils - Determination of solid fat content by pulsed NMR - Part 2: Indirect method (ISO 8292-2:2008)

ISO 8292-2:2008 specifies an indirect method for the determination of the solid fat content in animal and vegetable fats and oils (hereafter designated "fats") using low-resolution pulsed nuclear magnetic resonance spectrometry.
Two alternative thermal pre-treatments are specified: one for general purpose fats not exhibiting pronounced polymorphism and which stabilize mainly in the β'-polymorph; and one for fats similar to cocoa butter which exhibit pronounced polymorphism and stabilize in the β-polymorph. Additional thermal pre-treatments, which may be more suitable for specific purposes, are given in an informative annex.
The indirect method is less easy to carry out and less reproducible than the direct method, but is more accurate and more universally applicable to all fats.

Tierische und pflanzliche Fette und Öle - Bestimmung des Festanteils von Fett durch das Verfahren mit gepulster magnetischer Kernresonanz - Teil 2: Indirektes Verfahren (ISO 8292-2:2008)

Dieser Teil von ISO 8292 legt ein indirektes Verfahren zur Bestimmung des Festanteils von tierischen und
pflanzlichen Fetten und Ölen (nachfolgend als „Fette“ bezeichnet) mittels gepulster magnetischer Kernresonanz
(en: nuclear magnetic resonance, NMR) mit niedriger Auflösung fest.
Zwei alternative thermische Vorbehandlungen sind festgelegt: eine allgemeine Anwendung für Fette, die keine
ausgeprägte Polymorphie aufweisen und die in der β′-Polymorphie kristallisieren; und eine für
kakaobutterähnliche Fette, die eine ausgeprägte Polymorphie aufweisen und die in der β-Polymorphie
kristallisieren. Zusätzliche thermische Vorbehandlungen, die für bestimmte Zwecke geeigneter sein können,
sind in einem informativen Anhang angegeben.
Das indirekte Verfahren ist nicht so einfach durchzuführen und weniger reproduzierbar als das direkte
Verfahren, aber es ist genauer und universeller anwendbar auf alle Fette.
ANMERKUNG Ein direktes Verfahren ist in ISO 8292-1 festgelegt.

Corps gras d'origines animale et végétale - Détermination de la teneur en corps gras solides par RMN pulsée - Partie 2: Méthode indirecte (ISO 8292-2:2008)

L'ISO 8292-2:2008 spécifie une méthode indirecte pour la détermination de la teneur en corps gras solides dans des corps gras d'origine animale et végétale (appelés ci-après «corps gras») en utilisant un spectromètre de résonance magnétique nucléaire (RMN) pulsée à basse résolution.
Deux prétraitements thermiques possibles sont spécifiés: l'un pour les corps gras à usage général ne présentant pas de polymorphisme prononcé et qui se stabilisent principalement sous la forme polymorphe β', et l'autre pour des corps gras similaires au beurre de cacao qui présentent un polymorphisme prononcé et qui se stabilisent sous la forme polymorphe β. Des prétraitements thermiques supplémentaires, qui peuvent être plus adaptés pour des applications spécifiques, sont indiqués dans une annexe informative.
La méthode indirecte est moins facile à conduire et moins reproductible que la méthode directe, mais elle est plus précise et plus universellement applicable à tous les corps gras.

Živalske in rastlinske maščobe in olja - Določevanje trdnih maščob s pulzno jedrsko magnetno resonanco - 2. del: Posredna metoda (ISO 8292-2:2008)

Ta del ISO 8292 določa posredno metodo za določevanje trdnih maščob v živalskih in rastlinskih maščobah in oljih (v nadaljevanju navedeno kot »maščobe«) z nizko resolucijsko pulzno jedrsko magnetsko resonančno (NMR) spektrometrijo. Določeni sta dve alternativni toplotni predobdelavi:  ena za maščobe za splošno uporabo, ki ne izkazujejo poudarjenega polimorfizma in se stabilizirajo predvsem v  polimorfih, in ena za maščobe, ki so podobne kokosovemu maslu in izkazujejo poudarjen polimorfizem ter se stabilizirajo v  polimorfih.  Dodatne toplotne predobdelave, ki so lahko bolj primerne za določene namene, so podane v informativnem dodatku.  Posredna metoda je težje izvesti in je težje ponovljiva kot neposredna metoda, vendar je bolj natančna in bolj splošno uporabna za vse maščobe. OPOMBA: Neposredna metoda je določena v ISO 8292-1..
