ISO 21424 Iodine Analysis in Fish Tissue
Introduction to ISO 21424: ISO 21424, titled "Fishery Products - Determination of Iodine Content," is an international standard that specifies the methods for determining iodine content in fish tissue. This analysis is crucial for ensuring food safety and quality, particularly in seafood products.
The importance of this test lies in its role as a key indicator of the iodine fortification level in processed fish products. Iodine deficiency can have serious health implications, especially in areas where dietary intake of iodine-rich foods is low. By accurately measuring iodine content, manufacturers and regulators can ensure that fortified products meet the required standards.
Test Specimen: The specimen for this analysis is typically fish tissue, which includes muscle, liver, and other edible parts of the fish. Proper preparation is essential to achieve accurate results. This involves homogenizing the sample in a buffer solution to ensure even distribution of iodine across the sample.
Instrumentation: The standard specifies the use of atomic absorption spectroscopy (AAS) or inductively coupled plasma optical emission spectrometry (ICP-OES) for measuring iodine content. These instruments provide precise and accurate results, which are essential for compliance with international standards.
Acceptance Criteria: According to ISO 21424, the measured iodine content in fish tissue should be within a specified range that complies with local regulations or industry standards. Deviations from these criteria may indicate improper fortification or contamination issues.
