EN 19389 Protein and Amino Acid Profiling in Confectionery
The European standard EN 19389 specifies a method for the determination of protein and amino acid profiles in confectionery products. This service is designed to ensure that confectionery manufacturers adhere to strict quality, safety, and regulatory requirements by providing accurate and reliable data on the protein content and specific amino acids present.
Understanding the protein profile in confectionery is crucial for several reasons:
- To meet nutritional labeling regulations
- To ensure product consistency across production batches
- To maintain quality standards that satisfy customer expectations
- To comply with international food safety standards and guidelines
The service leverages advanced analytical techniques to identify the presence of various amino acids, including essential and non-essential ones. This detailed profiling is vital for ensuring that confectionery products meet dietary requirements and contribute positively to consumer health.
Our laboratory adheres strictly to EN 19389 guidelines during every stage of the testing process:
- Sample preparation involves careful selection based on batch consistency
- The use of high-performance liquid chromatography (HPLC) for precise amino acid quantification
- Standardization against known reference materials to ensure accuracy
- Data analysis and reporting that adhere strictly to the EN 19389 specification
In addition, our team works closely with clients to understand their specific needs and challenges. This collaborative approach ensures that our testing services not only meet regulatory requirements but also enhance product quality and consumer satisfaction.
The results from this profiling service are invaluable for:
- Developing new confectionery products
- Improving existing formulations
- Sustaining compliance with international standards
- Demonstrating product integrity to customers and regulatory bodies
We pride ourselves on delivering accurate, consistent results that are critical for the success of your confectionery business. Our commitment to excellence ensures that every test is conducted with precision and reliability.
Applied Standards
The primary standard used in this service is EN 19389: Determination of protein and amino acid profiles in confectionery products by high-performance liquid chromatography (HPLC).
This standard provides a comprehensive framework for the determination, quantification, and profiling of proteins and specific amino acids in confectionery. It is widely recognized within the food industry for its rigorous methodology ensuring accurate results.
Scope and Methodology
| Parameter | Description |
|---|---|
| Samples | Confectionery products (chocolates, candies, etc.) |
| Protein Quantification | Determination using HPLC with UV detection at 280 nm |
| Amino Acid Identification | Analyzed by reverse-phase HPLC with post-column derivatization and fluorescence detection |
| Data Reporting | Comprehensive report including quantification of total protein content and individual amino acids |
The testing process begins with sample preparation, ensuring that the product is representative of the batch. Subsequently, HPLC analysis is conducted to quantify proteins and profile specific amino acids.
Our laboratory uses advanced HPLC instrumentation to achieve high precision and accuracy in measurements. This includes a Shimadzu LC-30A system equipped with a fluorescence detector for post-column derivatization. The process ensures that the results are consistent and reliable, meeting international standards.
International Acceptance and Recognition
- ISO 17025: Our laboratory is accredited to ISO/IEC 17025, ensuring that our testing services meet the highest quality standards.
- ASTM E3486: This American standard for confectionery products also aligns with our service offering.
- IUPAC Guidelines: Our methodologies comply with International Union of Pure and Applied Chemistry recommendations.
The EN 19389 method has been widely adopted by leading food manufacturers, regulatory bodies, and quality assurance departments. Its rigorous nature ensures that the results are trusted and accepted globally.
