ISO 8288 Copper, Zinc and Iron Profiling in Food by Atomic Absorption
The ISO 8288 standard provides a robust protocol for the quantitative determination of copper, zinc, and iron levels in food products using atomic absorption spectroscopy (AAS). This service is essential for ensuring that food items meet regulatory requirements and quality standards. Copper, zinc, and iron are critical trace elements that play vital roles in human nutrition; their accurate quantification is paramount to maintaining public health.
The copper content in foods can influence the taste, color, and shelf life of products such as chocolate, cereals, and beverages. Excessive or insufficient levels may indicate contamination issues or nutritional deficiencies, respectively. Zinc is a key element for growth and immune function, while iron contributes to hemoglobin production and oxygen transport in blood. Ensuring the correct balance of these elements through precise testing helps manufacturers comply with international standards.
The procedure outlined in ISO 8288 involves several steps, starting with proper sample preparation to ensure accurate results. Samples are typically digested using acidic solutions before analysis by AAS. The use of precision instruments ensures that even minute quantities of the elements can be detected and quantified accurately. Post-analysis, data is processed according to the ISO 8288 guidelines to generate precise concentrations.
The reliability of this service extends beyond regulatory compliance; it also supports R&D efforts by providing insights into optimal ingredient combinations for enhanced product quality. For quality managers and procurement officers, accurate mineral profiling ensures that suppliers meet specified quality parameters consistently. This level of detail is crucial in maintaining the integrity of food products and safeguarding consumer health.
The atomic absorption spectroscopy method used adheres to strict international standards such as ISO 8288:2015, ensuring consistent and reliable results across different laboratories. The precision and accuracy of these tests make them indispensable tools for quality control in the food industry.
