Foodstuffs - Determination of trace elements - Determination of tin in fruit and vegetables preserved in cans by flame atomic absorption spectrometry (AAS)

This document specifies a method for the determination of tin in vegetable foods preserved in cans by atomic absorption spectrometry (AAS).
This method is applicable to the determination of extractable tin in fruits and vegetables and collaboratively tested in concentrations up to 350 mg/kg. It is a method for determination of tin in canned fruit and vegetables contaminated with migrated tin from the can. The method can be applied with the prescribed amount of sample to products with a maximum total dry matter of 30 percent. Products with higher total solid contents may be analysed using sample amounts less than 30 percent after corresponding dilution with deionised water.

Lebensmittel - Bestimmung von Elementspuren - Bestimmung von Zinn in Obst- und Gemüsekonserven mit Flammen-Atomabsorptionsspektrometrie (AAS)

Dieses Dokument legt ein Verfahren zur Bestimmung von Zinn in pflanzlichen Lebensmittelkonserven mit
Atomabsorptionsspektrometrie (AAS) fest.
Das Verfahren ist für die Bestimmung von extrahierbarem Zinn in Obst und Gemüse anwendbar und wurde in
einem Ringversuch für Konzentrationen von bis zu 350 mg/kg geprüft. Es ist ein Verfahren zur Bestimmung
von Zinn in Obst- und Gemüsekonserven, die mit Zinn verunreinigt sind, das aus der Dose migriert ist. Das
Verfahren kann mit der vorgeschriebenen Probenmenge bei Erzeugnissen angewendet werden, deren Ge-samtgehalt
an Trockensubstanz höchstens 30 % beträgt. Erzeugnisse mit einem höheren Gehalt an Gesamt-trockensubstanz
können analysiert werden, indem Probenmengen von weniger als 30 % nach der ent-sprechenden
Verdünnung mit deionisiertem Wasser verwendet

This Technical Specification (CEN/TS) was approved by CEN on 7 August 2006 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

1 Scope
This document specifies a method for the determination of tin in vegetable foods preserved in cans by flame
atomic absorption spectrometry (AAS).
This method is applicable to the determination of extractable tin in fruits and vegetables and collaboratively
tested in concentrations from 25 mg/kg to 350 mg/kg. It is a method for determination of tin in canned fruit and
vegetables contaminated with migrated tin from the can. The method can be applied with the prescribed
amount of sample to products with a maximum total dry matter of 30 %. Products with higher total solid
contents may be analysed using sample amounts less than 30 % after corresponding dilution with deionised
water.
