EN 16318 Protein Measurement in Pet Foods
The European Standard EN 16318 specifies the method for determining the protein content in pet foods. This standard is particularly relevant for quality managers, compliance officers, R&D engineers, and procurement teams involved with pet food manufacturing or sourcing.
Protein is a critical component of pet food as it supports growth, repair of tissues, and immune function. Ensuring accurate measurement of the protein content in pet foods is essential to meet nutritional requirements and comply with regulatory standards. This service employs advanced analytical techniques to measure total nitrogen content, which correlates directly with the crude protein content.
The procedure outlined in EN 16318 involves the digestion of the food sample using a strong acid followed by titration with sodium hydroxide solution. The total nitrogen is then converted to an equivalent amount of protein based on the factor 6.25, which represents the average molecular weight ratio of nitrogen to protein.
The method is designed to provide precise and accurate results that are repeatable within a specified range. This ensures consistency across batches and helps in maintaining product quality over time. The standard also provides guidance on sample preparation, including the appropriate dilution factors for different types of pet food samples.
Using this standard allows manufacturers to ensure compliance with EU regulations regarding pet food labeling, which requires that protein content be stated as part of the guaranteed analysis. This information is crucial for consumers to understand the nutritional value of their pets' diets accurately.
| Sample Type | Digestion Time | Titration Volume Range | Precision |
|---|---|---|---|
| Canine Food | 30 minutes | 5-12 mL | ±0.2% relative standard deviation (RSD) |
| Feline Food | 45 minutes | 8-15 mL | ±0.3% RSD |
The digestion time and titration volume range vary depending on the type of pet food being analyzed, ensuring that each sample is handled appropriately for optimal results.
