Protein & Amino Acid Profile Testing
In the realm of food and feed safety testing, protein and amino acid profile analysis is a critical component that ensures the integrity and quality of products. This process involves detailed examination of proteins present in samples to identify their amino acid composition, which is essential for regulatory compliance, nutritional labeling, and product development.
Protein content can vary widely depending on the source material, processing methods, and intended use. Accurate determination of protein quantity and quality ensures that food products meet dietary requirements and comply with international standards. For instance, in infant formulas or pet foods, precise control over amino acid profiles is paramount to support healthy growth.
The amino acids arginine, lysine, methionine, tryptophan, and histidine are particularly important as they serve specific biological functions within the body. Ensuring adequate levels of these essential amino acids in feeds or dietary supplements can prevent deficiencies that may lead to health issues.
Protein and amino acid profile testing is also crucial for verifying claims made on product labels regarding protein content. Mislabeling could mislead consumers about the nutritional value of their purchases, which is why accurate measurement is vital. Regulatory bodies such as the FDA and European Food Safety Authority (EFSA) enforce strict guidelines to prevent such occurrences.
In addition, this testing helps in identifying potential allergens or harmful substances associated with certain proteins. For example, gluten intolerance is a growing concern among consumers, and the ability to detect even trace amounts of problematic proteins is crucial for maintaining public health safety.
- Customer Impact: Compliance with regulatory standards enhances brand reputation and trustworthiness.
- Satisfaction: Assurance that products meet nutritional requirements fosters consumer confidence.
To achieve accurate results, rigorous sample preparation is necessary. This includes thorough extraction of proteins from the matrix using appropriate solvents followed by separation techniques like sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Once separated, further analysis through high-performance liquid chromatography (HPLC) or mass spectrometry provides quantitative and qualitative data about the amino acid composition.
Understanding how different proteins behave under various conditions is key to optimizing product formulations. For instance, understanding which amino acids are most readily absorbed by organisms can guide improvements in feed efficiency or nutritional content of foods.
At Eurolab, we utilize advanced analytical instruments including but not limited to liquid chromatography tandem mass spectrometry (LC-MS/MS) and gas chromatography mass spectrometry (GC-MS), ensuring reliable identification and quantification of amino acids. Our experienced team applies international standards such as ISO 15516:2017 for protein determination in foodstuffs, guaranteeing consistency across all analyses.
Our commitment to quality extends beyond just executing tests; it encompasses continuous improvement through ongoing training, investment in cutting-edge technology, and adherence to best practices. By leveraging these resources, Eurolab ensures that every client receives accurate, timely results tailored specifically to their needs.
Scope and Methodology
Eurolab specializes in comprehensive protein and amino acid profile testing services designed to meet the diverse needs of our clients. Our scope includes not only determining total protein content but also assessing individual amino acids present in complex matrices such as grains, legumes, animal by-products, and processed foods.
- Sample Collection: Proper collection is critical to ensure representative samples for analysis.
- Extraction: Utilizing appropriate solvents helps release proteins from the sample matrix effectively.
- Separation: Techniques like SDS-PAGE separate different protein types based on size and charge.
The next step involves quantification of separated proteins using spectrophotometric methods. Following this, individual amino acids are isolated and identified via HPLC or MS techniques. This process allows us to provide detailed reports specifying both overall protein content and specific amino acid profiles.
Our approach adheres strictly to recognized international standards like ISO 15516:2017 for protein determination in foodstuffs, ensuring consistency and reliability of our findings. By following these protocols rigorously, we maintain high-quality standards that satisfy regulatory requirements globally.
