AOAC 975.43 Vitamin B12 Assay in Meat and Fish

The AOAC International Standard Method 975.43 is a widely recognized procedure for the analysis of vitamin B₁₂ in meat and fish products. This method ensures accurate quantification of cobalamin (vitamin B₁₂) by utilizing high-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (LC/MS-MS). The assay is particularly valuable for quality assurance, regulatory compliance, and research purposes within the food industry.

This method is crucial for ensuring that meat and fish products meet nutritional labeling requirements. It also helps in identifying potential contamination or adulteration issues by verifying the presence of vitamin B₁₂. The assay can detect even trace amounts of cobalamin, making it highly sensitive and reliable for both quality control and research applications.

The AOAC 975.43 method involves several steps to ensure accurate results. First, the sample is prepared by extracting vitamin B₁₂ from the meat or fish matrix using a suitable solvent. The extraction efficiency is critical for obtaining reliable results, and specific protocols are provided in the standard.

The extracted solution is then analyzed using HPLC-MS/MS. This sophisticated analytical technique provides high specificity and sensitivity, allowing for precise quantification of cobalamin. The method's accuracy and precision are further enhanced by the use of internal standards and calibration curves.

Quality managers and compliance officers rely on this method to ensure that their products meet stringent nutritional requirements and regulatory guidelines. R&D engineers utilize it to develop new formulations or improve existing products, while procurement teams can verify the authenticity and quality of raw materials used in production.

The AOAC 975.43 method is internationally recognized and widely accepted in various regions including Europe, North America, and Asia. Its robustness and reliability make it a preferred choice for laboratories conducting nutritional analysis.
