EN 18462 Determination of Protein-to-Energy Ratio in Diet Foods
The European Standard EN 18462 provides a standardized method for determining the protein-to-energy ratio (PER) in diet foods. This parameter is crucial for assessing the nutritional quality and health benefits of dietary products, especially those targeting individuals with specific dietary needs such as athletes, diabetics, or those managing weight.
The PER is an important indicator that helps to evaluate the efficiency of a food item's macronutrient profile in relation to its energy content. A higher PER indicates better utilization of protein by the human body for muscle repair and growth. This test is particularly relevant when developing diet foods because it ensures that the product meets specific nutritional guidelines, thereby providing accurate information to consumers about their dietary intake.
The EN 18462 method involves a series of steps designed to ensure precise measurement of both protein and energy content in the sample. The process begins with thorough sampling and preparation according to the standard's specifications. Once prepared, the sample is subjected to gravimetric analysis for determining its dry matter content, followed by calorimetric determination of the energy content.
A key aspect of this service involves understanding how different food constituents contribute to the PER calculation. Proteins are identified through amino acid profiles and their total nitrogen content, while carbohydrates and fats are quantified using standard chemical methods. These values form the basis for calculating the PER, which is expressed as a percentage indicating the proportion of protein relative to the total energy content.
Our laboratory adheres strictly to EN 18462, ensuring that all determinations are accurate and reliable. We use state-of-the-art equipment calibrated according to international standards, including calorimeters for precise energy measurement and spectrophotometers for protein quantification. Compliance with these stringent protocols guarantees that the results we provide meet the highest quality assurance levels.
For clients looking to optimize their diet food products or ensure compliance with regulatory requirements, our EN 18462 service offers a comprehensive approach to testing. By leveraging this standard, businesses can enhance product development processes and improve overall consumer satisfaction through more accurate nutritional labeling.

Scope and Methodology
The scope of the EN 18462 Determination service encompasses a detailed procedure for assessing the protein-to-energy ratio in diet foods. This involves several critical stages, starting with sample preparation which includes homogenization and conditioning to ensure uniformity across all samples tested.
Subsequently, gravimetric analysis is performed to determine the dry matter content of each sample. Simultaneously, calorimetry measures the total energy content through combustion in an oxygen bomb calorimeter. Spectrophotometric techniques are employed for protein quantification using methods like the Biuret or Kjeldahl nitrogen determination.
The collected data is then processed mathematically to calculate the PER according to the formula specified in EN 18462:
PER = (Protein Content / Energy Content) × 100
This calculation provides a clear indication of how efficiently the protein content contributes towards meeting the energy requirements. Our laboratory ensures that all calculations are done meticulously, adhering strictly to ISO standards for accuracy and reliability.
Our methodology also includes quality control measures such as duplicate testing, reference material validation, and ongoing method calibration to maintain precision throughout every step of the process. By doing so, we guarantee consistent results that can be trusted by both manufacturers and regulatory bodies alike.
