BS ISO 20938:2008

Overview

BS ISO 20938:2008 specifies a method for determining the moisture content in instant coffee using the Karl Fischer titration technique. This standard is crucial for ensuring the quality and stability of instant coffee products, as moisture content directly affects shelf life, flavour, and overall consumer satisfaction.

Key Requirements

The standard outlines the following key requirements for the Karl Fischer method:

• Sample Preparation: Proper sampling techniques must be employed to ensure representative samples are tested.
• Reagents: Only high-purity reagents should be used to avoid contamination and ensure accuracy in moisture measurement.
• Calibration: Regular calibration of the titration apparatus is necessary to maintain precision in results.
• Procedure: The method involves dissolving the coffee sample in a suitable solvent and titrating with Karl Fischer reagent until the endpoint is reached.

Implementation Benefits

Adopting BS ISO 20938:2008 provides several practical implementation benefits:

• Quality Assurance: Regular moisture testing ensures that instant coffee products meet quality standards, enhancing consumer trust.
• Extended Shelf Life: By controlling moisture levels, manufacturers can significantly extend the shelf life of their products.
• Consistency: The standardised method allows for consistent results across different batches, which is vital for maintaining product integrity.
• Regulatory Compliance: Adhering to this standard helps manufacturers comply with food safety regulations and industry best practices.

Compliance Value

Compliance with BS ISO 20938:2008 is essential for food manufacturers aiming to meet both national and international food safety standards. The standard provides a scientifically validated method for moisture determination, which is critical for:

• Consumer Safety: Ensuring that products are safe for consumption by preventing microbial growth associated with high moisture levels.
• Market Competitiveness: Companies that adhere to recognised standards can enhance their market position by demonstrating commitment to quality.
• Traceability: Following a recognised standard aids in maintaining traceability throughout the production process, which is increasingly demanded by consumers and regulators alike.

In conclusion, BS ISO 20938:2008 is a vital standard for the food technology sector, specifically for instant coffee manufacturers. By implementing this standard, companies can ensure product quality, enhance consumer safety, and achieve compliance with regulatory requirements.
