ISO 26034-6:2021 is a technical standard that provides guidelines for the determination of inorganic arsenic content in food products. It specifies a method using hydride generation and atomic absorption spectrometry (HG-AAS) for the quantitative analysis of inorganic arsenic in various food samples. This standard aims to ensure the safety and quality of food by establishing reliable analytical procedures.
Why is it important?
The presence of inorganic arsenic in food can pose significant health risks, as it is a known carcinogen. Regular monitoring and control of its levels are crucial for both consumer protection and regulatory compliance. ISO 26034-6:2021 sets a standardized approach to determine inorganic arsenic content, allowing for accurate and comparable results across different laboratories and regions.
Methodology and Testing Procedure
The methodology described in ISO 26034-6:2021 involves extracting inorganic arsenic from food samples using appropriate acids and then converting it into arsine gas through hydride generation. The arsine gas is then quantified using atomic absorption spectrometry.
The testing procedure consists of several steps. First, the food sample is collected and prepared for analysis. Then, the extraction of inorganic arsenic is performed under controlled conditions. The resulting extract is subsequently treated to generate arsine gas, which is separated and measured using the specified instrumentation. The obtained measurements are then used to calculate the final inorganic arsenic content in the food sample.
Benefits and Applications
The implementation of ISO 26034-6:2021 brings several benefits to the food industry and regulatory bodies. It allows for more accurate measurements of inorganic arsenic content, leading to better risk assessment and management strategies. By ensuring reliable and consistent data, this standard enables effective monitoring of food products throughout the supply chain.
This technical standard finds applications in various sectors such as food production, import/export control, and regulatory compliance. It provides a harmonized framework for laboratories and organizations involved in food safety testing, facilitating international trade and promoting global food safety standards.
