Vinegar - Isotopic analysis of acetic acid and water - Part 2: 13C-IRMS analysis of acetic acid
This European standard specifies an isotopic method to control the authenticity of vinegar. This method is applicable on acetic acid of vinegar (from cider, alcohol, wine, etc.) in order to characterise the botanical origin of acetic acid and to detect adulterations of vinegar using synthetic acetic acid or acetic acid from not allowed origin (together with the method described in FprEN 16466-1).
The isotopic analysis of the extracted acetic acid by 13C-IRMS is based on a similar method already normalised for wine analysis [2].
Essig - Isotopenanalyse von Essigsäure und Wasser - Teil 2: 13C-IRMS-Analyse von Essigsäure
Diese Europäische Norm legt ein isotopenanalytisches Verfahren zur Überprüfung der Authentizität von Essig fest. Dieses Verfahren ist anwendbar auf Essigsäure aus Essig (aus Apfelwein, Alkohol, Wein usw.), um den botanischen Ursprung der Essigsäure zu charakterisieren und um Verfälschungen von Essig durch Verwendung synthetischer Essigsäure oder Essigsäure aus einem nicht zulässigen Ursprung nachzuweisen (in Kombination mit dem in EN 16466 1 beschriebenen Verfahren).
Die Isotopenanalyse der extrahierten Essigsäure durch 13C IRMS beruht auf einem ähnlichen Verfahren, das bereits für die Weinanalyse genormt wurde [2].
Vinaigre - Analyse isotopique de l'acide acétique et de l'eau - Partie 2 : Analyse SMRI-13C de l'acide acétique
La présente Norme européenne spécifie une méthode isotopique de contrôle de l’authenticité du vinaigre. La présente méthode s’applique à l’acide acétique de vinaigre (de cidre, d’alcool, de vin, etc.) afin de caractériser l’origine botanique de l’acide acétique et de détecter des adultérations du vinaigre utilisant de l’acide acétique synthétique ou de l’acide acétique d’une origine non autorisée (en complément de la méthode décrite dans l’EN 16466-1).
L’analyse isotopique par SMRI-13C de l’acide acétique extrait est fondée sur une méthode similaire à celle de l’analyse du vin, déjà normalisée [2].
Kis - Izotopska analiza ocetne kisline in vode - 2. del: 13C-IRMS-analiza ocetne kisline
Ta evropski standard določa izotopsko metodo za nadzorovanje pristnosti kisa. Ta metoda se uporablja za ocetno kislino v kisu (iz mošta, alkohola, vina itd.), da se opredelijo značilnosti botaničnega izvora ocetne kisline in zazna ponarejanje kisa z uporabo sintetične ocetne kisline ali ocetne kisline nedovoljenega izvora (skupaj z metodo iz standarda EN 16466-1). Izotopska analiza ekstrahirane ocetne kisline s 13C-IRMS temelji na podobni metodi, ki je že normalizirana za analizo vina.

Overview
SIST EN 16466-2:2013 sets out a European Standard method for the isotopic analysis of acetic acid in vinegar using 13C Isotope Ratio Mass Spectrometry (13C-IRMS). Developed and published by CEN, this standard supports authenticity and purity control for vinegars, particularly in detecting adulteration with synthetic acetic acid or acid from unauthorized sources. The method applies to vinegars from various origins, including wine, cider, and alcohol vinegar, and forms part of a series on verifying vinegar composition through isotopic techniques.
Key Topics
Isotopic Analysis for Vinegar Authenticity
The standard specifies how to determine the isotopic ratio of carbon (13C/12C) in the acetic acid extracted from vinegar, using Isotope Ratio Mass Spectrometry (IRMS). This ratio is key to characterizing the botanical origin of the acetic acid.Detection of Adulteration
By analyzing isotopic signatures, SIST EN 16466-2:2013 can distinguish vinegar made via permitted biotechnological processes from vinegar adulterated with synthetic acetic acid or acetic acid from petrochemical or wood pyrolysis sources.Extraction and Preparation Procedures
Acetic acid is extracted from vinegar samples using solvents such as diethyl ether. Careful extraction and purification steps are followed before isotopic analysis.Measurement Principles
The extracted acetic acid undergoes combustion, converting it to CO2, and an IRMS instrument records the 13C/12C ratio. Accuracy, precision, and proper calibration using reference materials are emphasized.Reporting Requirements
The method mandates thorough reporting of sample identification, analysis results, and all deviations from the prescribed method, ensuring clear traceability and reproducibility.
Applications
Implementing SIST EN 16466-2:2013 provides significant benefits to food quality control and industry compliance:
Food Authentication
Food control laboratories and vinegar producers use this method to verify the authenticity of vinegars, ensuring they derive from permitted agricultural processes rather than synthetic or unauthorized sources.Adulteration Prevention
Regulatory agencies utilize this standard to detect and prevent market fraud involving the substitution of natural vinegar with cheaper synthetic acetic acid.Quality Assurance in Production
Vinegar manufacturers apply the isotopic method to support label claims about origin (e.g., wine vinegar, cider vinegar) and maintain consumer trust.Compliance with European Regulations
SIST EN 16466-2:2013 helps stakeholders meet EU regulations regarding the permitted origins and definitions of vinegar products, as outlined in EN 13188 and relevant European Commission regulations.

a) transformation of sugars to ethanol and
b) transformation of ethanol to acetic acid.
Conversely EN 13189 defines acetic acid as "Product made from materials of non-agricultural origin".
Wine vinegar is defined by the European Regulations 479/2008 and 491/2009 as the product obtained exclusively from the acetous fermentation of wine, which is in turn defined as the product exclusively obtained from the alcoholic fermentation of fresh grapes, whether crushed or not, or of grape must.
In all types of vinegar, both the ethanol and the acetic acid should be obtained by a biotechnological process, and the use of acetic acids obtained from either petroleum derivatives or the pyrolysis of wood is not permitted according to the above definitions.
The isotopic analysis of acetic acid extracted from vinegar by 2H-SNIF-NMR and 13C-IRMS enables the distinction of grape origin from other sources, such as beet, cane, malt, apple and synthesis [1].
