    Journal of AOAC International·1994

    Area of Science:

    • Analytical Chemistry
    • Food Science
    • Environmental Science

    Background:

    • Accurate quantification of tin in food is crucial for food safety and regulatory compliance.
    • Existing methods for tin analysis may require validation for diverse food matrices.

    Purpose of the Study:

    • To validate a specific analytical method for tin determination in various food matrices.
    • To assess the reliability and transferability of the tin quantification method across different laboratories.

    Main Methods:

    • Food samples (green beans, applesauce, fruit juice) were fortified with tin at three concentration levels.
    • Sample digestion involved a nitric acid-sulfuric acid mixture.
    • Methanol was added to enhance the absorption signal.
    • Tin analysis was performed using nitrous oxide-acetylene flame atomic absorption spectroscopy.

    Main Results:

    • Eight laboratories participated in the collaborative study.
    • Six laboratories adhered to the prescribed digestion and analysis methodology.
    • All reported results were deemed acceptable, indicating method robustness.
    • The method demonstrated good performance across different food types.

    Conclusions:

    • The validated analytical method is suitable for the determination of tin in green beans, applesauce, and fruit juice.
    • The method's reliability was confirmed through a collaborative interlaboratory study.
    • The method has been officially adopted as an interim first action method.
