ISO 24114:2011

Overview

ISO 24114:2011 is an international standard established by the International Organization for Standardization (ISO) that specifies the criteria for authenticity of soluble (instant) coffee. With the expansive global trade of instant coffee, this standard provides essential guidelines to ensure product purity and consumer protection. The primary goal is to prevent adulteration-where non-coffee materials are added to soluble coffee but not declared-thus maintaining fair competition and truthful product labeling.

Through scientifically sound measures, ISO 24114:2011 defines how to detect and quantify permissible carbohydrate content in pure soluble coffee. This standard supports manufacturers, regulators, and consumers by defining acceptable quality criteria for instant coffee authenticity based on carbohydrate profiling.

Key Topics

• Definition of Pure Soluble Coffee
  Pure soluble coffee comprises products made exclusively from roasted coffee bean extracts, as outlined by international and national regulations.

• Soluble Coffee Mixtures and Adulteration
  Mixtures containing extracts from coffee beans mixed with other substances must be clearly labeled. Adulterated soluble coffee, which is sold as pure but contains undisclosed additives, is identified by abnormal carbohydrate profiles.

• Carbohydrate Content as an Authenticity Indicator
  The standard uses the content of two key carbohydrates-total glucose and total xylose-as indicators. Their levels are established through statistical analysis of over 1,000 commercial samples worldwide.

• Analytical Method
  Authenticity testing follows the procedure specified in ISO 11292, involving high-performance anion-exchange chromatography to precisely measure carbohydrate content.

• Specification Limits for Authenticity
  ISO 24114 sets maximum permitted concentrations for total glucose (2.46% mass fraction) and total xylose (0.45% mass fraction) in pure soluble coffee. Exceeding these thresholds indicates likely adulteration, accounting for analytical uncertainty.

Applications

• Quality Control for Manufacturers
  Instant coffee producers can apply ISO 24114 to validate product purity before market release, ensuring compliance with labeling and regulatory requirements.

• Regulatory Compliance and Market Surveillance
  Food safety authorities and inspection agencies use this standard to verify claims of 100% pure instant coffee, maintaining fair trade practices and protecting consumers from fraudulent products.

• Supplier Verification and Trade Assurance
  Importers, exporters, and retailers rely on the carbohydrate content criteria to assess the authenticity of soluble coffee batches, reducing risks associated with adulterated goods.

• Consumer Confidence
  By enforcing testing methods and specification limits, ISO 24114 helps establish trust in instant coffee products, supporting transparency and truthful product declaration.
