ISO 8070 Calcium and Magnesium Measurement in Milk by AAS
The measurement of calcium (Ca²⁺) and magnesium (Mg²⁺) in milk is crucial for ensuring product quality, safety, and compliance with international food standards. This service adheres to the ISO 8070 protocol, which specifies the use of atomic absorption spectrophotometry (AAS) for accurate quantification of these essential elements. The accuracy and precision provided by this method are particularly important in dairy industries where slight variations can significantly impact product quality.
Calcium and magnesium play critical roles in milk composition. Calcium is involved in the formation of casein micelles, which are vital for the texture and structure of milk products. Adequate levels ensure better processing stability during cheese production, yogurt manufacturing, and other dairy operations. Magnesium contributes to the regulation of muscle contraction, energy metabolism, and bone health—a key factor in infant formula and specialty nutritional products.
The procedure involves several steps, starting with sample preparation where raw milk is filtered and diluted according to ISO 8070 guidelines to ensure accurate results. The use of high-purity reagents and precise calibration are paramount for achieving reliable outcomes. Once prepared, the samples are introduced into the AAS instrument, which measures the absorption of light at specific wavelengths corresponding to calcium and magnesium.
The AAS method is preferred over other analytical techniques due to its simplicity, selectivity, and minimal interference from other elements present in milk. This non-destructive technique allows for repeatable measurements, making it suitable for quality control processes as well as research and development activities aimed at optimizing dairy product formulations.
Compliance with ISO 8070 ensures that the results are consistent across different laboratories and regions, which is essential for maintaining a global standard in milk quality. This method is widely accepted by regulatory bodies and industry stakeholders worldwide, providing confidence to consumers and businesses alike about the purity and safety of dairy products.
Understanding the importance of these elements within the broader context of food testing underscores why this service is indispensable for ensuring product integrity. By leveraging ISO 8070, we provide a robust framework that supports continuous improvement in dairy processing and formulation practices.
