EN 15131 Determination of Amino Acids in Infant Formula
The European Standard EN 15131:2008 specifies the procedure for determining the amino acid composition of infant formula. This method is crucial as it ensures that the nutritional content meets stringent regulatory requirements, particularly focusing on essential and conditionally essential amino acids which are vital during infancy.
The standard applies to a wide range of products intended for infants under 12 months, including powdered formulas, ready-to-feed preparations, and liquid concentrates. The testing is performed using high-performance liquid chromatography (HPLC), typically equipped with a post-column derivatization system that allows precise measurement of different amino acids.
The primary aim of this method is to ensure the accurate determination of free amino acid content in infant formula, which directly impacts infant health and development. Compliance with EN 15131 is mandatory for manufacturers aiming to meet European regulations on food safety and quality.
Testing under this standard involves several steps: sample preparation, extraction, derivatization, separation by HPLC, detection, and quantification of individual amino acids. The process ensures that all essential amino acids are present in the correct proportions necessary for optimal infant growth and development.
The results from EN 15131 testing play a significant role in product formulation, quality assurance, and regulatory compliance. Compliance with this standard not only protects infants but also builds trust with consumers regarding the safety and efficacy of the product.
Given the critical nature of infant nutrition, accurate and reliable determination of amino acids is paramount. Eurolab's proficiency in EN 15131 testing guarantees that every batch produced meets stringent quality standards set by international regulations.
Scope and Methodology
The scope of the EN 15131:2008 standard encompasses the determination of free amino acids in infant formula. This method is particularly important for ensuring that essential and conditionally essential amino acids are present in adequate amounts to support healthy growth and development.
- Free Amino Acids: The analysis focuses on determining the concentration of 18 individual amino acids, including both essential and non-essential ones.
- Sample Preparation: Samples are prepared by dissolving a known quantity of the infant formula in a suitable solvent. This step ensures that all components are available for extraction.
- Extraction and Derivatization: The extracted amino acids undergo derivatization using an appropriate reagent to enhance their detection capabilities. This process is critical as it improves sensitivity and specificity of the HPLC method.
- HPLC Separation: Chromatographic separation is achieved through a series of columns optimized for different types of amino acids, allowing for precise identification and quantification.
- Detection and Quantification: The separated peaks are detected using a suitable detector, typically UV-Vis or fluorescence detection, which provides quantitative data on the presence and concentration of each amino acid.
The methodology ensures that all essential amino acids—such as histidine, isoleucine, leucine, methionine, phenylalanine, threonine, tryptophan, and valine—are present in adequate amounts. These are critical for the synthesis of proteins necessary for normal growth and development.
Testing under EN 15131 also evaluates non-essential amino acids like aspartic acid, glutamic acid, glycine, alanine, serine, cysteine, proline, tyrosine, and arginine. While these are not essential for infants, they still play a significant role in maintaining overall health.
The standard provides detailed guidelines on the calibration of instruments, preparation of reagents, and conditions under which testing should be conducted to ensure accurate results.
