EN 16935 Determination of Protein Efficiency Ratio in Food
The European Standard EN 16935 is a crucial tool in the food and feed industry, providing guidance on how to determine the Protein Efficiency Ratio (PER). This ratio is essential for assessing the quality of protein sources used in formulated foods. PER measures the effectiveness of dietary proteins in promoting growth using intact animals as biological indicators.
The standard applies specifically to the determination of PER in complete or semi-complete animal feed and human food products, which contain more than 10% crude protein on a dry matter basis. This makes it particularly relevant for those involved in quality management, compliance officers, R&D engineers, and procurement teams within the sector.
The procedure outlined in EN 16935 involves rearing young animals or birds under controlled conditions to determine their growth rate based on dietary protein intake. The test can be performed using either single-sex chicks or intact growing rats as biological indicators for different types of food products.
Compliance with this standard ensures that food and feed manufacturers meet the highest quality standards, thereby safeguarding consumer health and safety. The process not only guarantees accurate measurement but also aids in optimizing product formulations to enhance nutritional value.
The methodology described in EN 16935 involves several critical steps including sample preparation, feeding regimes, monitoring growth parameters, and statistical analysis. Proper sample handling is vital; samples must be representative of the entire batch they are taken from. Feeding protocols need careful adherence to ensure consistent results across multiple trials.
Statistical methods play a key role in interpreting data correctly. This includes calculating means and standard deviations for growth rates among groups fed different levels of protein. Reporting should include these calculations along with descriptions of experimental conditions used during the study.
The importance of accurate PER determination cannot be overstated, especially given its direct impact on public health outcomes related to nutrition. By adhering strictly to EN 16935 guidelines, stakeholders contribute significantly towards maintaining high standards in both production and consumption practices.
Industry Applications

- Agricultural Research: Studying how different protein sources affect livestock development.
- Food Safety: Ensuring that proteins used in processed foods are safe for human consumption.
- Consumer Health: Helping to design diets that meet individual nutritional needs more effectively.
Environmental and Sustainability Contributions
The use of EN 16935 contributes positively to environmental sustainability by encouraging efficient utilization of resources. By ensuring that protein sources used in animal feed are highly effective, there is reduced waste across the supply chain. Additionally, improved PER values translate into better resource efficiency and lower emissions per unit output.
For instance, when formulating feeds using this standard, less raw material might be required to achieve similar growth rates compared to non-compliant methods. This leads to savings in feed costs while simultaneously decreasing environmental footprints associated with feed production processes.
Furthermore, compliance helps reduce overproduction of certain crops meant for animal feed, thus preventing potential harm to ecosystems through excessive cultivation practices. Overall, adhering to EN 16935 aligns perfectly with broader goals related to sustainable agriculture and responsible resource management.
Use Cases and Application Examples
- Case Study: A large poultry farm conducted trials using various protein supplements according to EN 16935. Results showed significant improvements in weight gain without increases in feed consumption, indicating enhanced PER.
- Example: In a university setting, researchers used this standard during experiments aimed at developing new plant-based meat alternatives that could mimic traditional animal proteins.
In another scenario, an international organization involved in food aid distribution applied EN 16935 to evaluate the nutritional quality of donated supplies before they were distributed. This ensured that beneficiaries received products capable of providing essential nutrients efficiently.
