AOAC 984.27 Calcium and Magnesium Measurement in Dairy Products
The AOAC International Method 984.27 is a widely recognized procedure used to determine the calcium and magnesium content in dairy products such as milk, cheese, yogurt, cream, and other related formulations. This method is crucial for ensuring product quality, compliance with regulatory standards, and maintaining nutritional integrity.
Calcium and magnesium are essential minerals that play vital roles in various biological processes. Calcium supports bone health, muscle function, and nerve signaling, while magnesium aids in energy production, protein synthesis, and the regulation of blood pressure. In dairy products, these minerals contribute to product quality and consumer health benefits.
The AOAC 984.27 procedure involves a series of steps that include sample preparation, digestion, and subsequent analysis using atomic absorption spectroscopy (AAS). The method is standardized in AOAC International standards to ensure consistency and accuracy across laboratories.
The primary goal of this test is not only to quantify the calcium and magnesium content but also to provide a reliable basis for quality control, product formulation, and compliance with international food safety guidelines. By adhering to this method, manufacturers can ensure that their products meet customer expectations and regulatory requirements.
Sample preparation in AOAC 984.27 involves diluting the dairy sample with water and then digesting it using a mixture of nitric acid and hydrogen peroxide at elevated temperatures. This process breaks down complex compounds into simpler forms, making the minerals more accessible for analysis. After digestion, the solution is filtered to remove any remaining particulates.
The digested sample is then analyzed using atomic absorption spectroscopy (AAS). AAS measures the absorption of light by free atoms in a gaseous state and is highly sensitive to trace elements like calcium and magnesium. The instrument emits light at specific wavelengths corresponding to these elements, which are absorbed by their respective ions in the sample solution.
The calibration curve method is used for quantification, where known concentrations of standard solutions are measured under identical conditions as the samples. This allows for accurate determination of the target minerals' concentration in the dairy products being analyzed.
Acceptance criteria for AOAC 984.27 typically include a precision limit of ±0.5% relative standard deviation (RSD) and accuracy within ±1% of the true value when compared to certified reference materials or other reliable methods. Compliance with these standards ensures that the results are both reproducible and accurate.
