EN 14105 Glyceride Composition Analysis in Oils
The European standard EN 14105 specifies the method for determining the glyceride composition of oils and fats, including triglycerides, diglycerides, monoglycerides, and free fatty acids. This analysis is crucial for ensuring product quality, consistency, and compliance with regulatory standards.
Accurate measurement of glyceride composition helps in identifying potential adulteration or contamination issues. It also aids in the optimization of production processes by providing insights into feedstock variability. For instance, in the food industry, this analysis can reveal whether oils contain a high proportion of free fatty acids that may affect shelf life and flavor stability.
The glyceride composition analysis is performed using chromatographic techniques such as Gas Chromatography (GC) or Liquid Chromatography (LC). These methods are sensitive enough to detect even minor changes in the glyceride profile, which can be indicative of oil quality. The standard prescribes specific conditions for sample preparation and instrumental settings to ensure reproducibility and accuracy.
Sample preparation involves extracting the glycerides from the oil matrix using a solvent like methanol or ethanol followed by saponification with sodium hydroxide. After separation, the resulting mixture is subjected to GC or LC analysis. Chromatograms obtained provide quantitative data on individual components of the glyceride composition.
The results are typically reported as percentages of total fatty acids present in each glyceride form. Compliance with EN 14105 ensures that all parties involved—from suppliers to consumers—can rely on accurate and consistent measurements. This is particularly important for businesses dealing internationally, where regulatory standards may differ but adherence to recognized international norms like EN 14105 enhances trust and reliability.
Given the increasing demand for transparency and traceability in food supply chains, this service plays a vital role in maintaining high standards of quality across industries. By leveraging advanced analytical techniques, our laboratory ensures that every test adheres strictly to EN 14105 guidelines, thus providing clients with reliable data they can trust.
To summarize, glyceride composition analysis underpins the integrity of oil-based products by offering detailed insights into their makeup. This knowledge is invaluable for manufacturers looking to enhance product quality and ensure regulatory compliance.

Scope and Methodology
The scope of EN 14105 encompasses the determination of glycerides in oils and fats, including triglycerides, diglycerides, monoglycerides, and free fatty acids. This analysis is applicable to a wide range of edible oils such as vegetable oils (e.g., rapeseed oil), animal fats (e.g., lard), and refined products derived from these sources.
The methodology prescribed in EN 14105 involves several key steps:
- Sample Collection: Representative samples are collected according to good sampling practices, ensuring that the sample accurately reflects the characteristics of the entire batch or shipment.
- Saponification and Extraction: The oil undergoes saponification with sodium hydroxide, which converts glycerides into fatty acid salts. These salts are then extracted using a solvent like methanol.
- Purification and Concentration: Further purification steps may be necessary to remove impurities before the final concentration step.
- Analysis: The purified extract is analyzed by Gas Chromatography (GC) or Liquid Chromatography (LC), depending on the specific requirements of the analysis. GC provides excellent separation capabilities, while LC offers higher sensitivity for trace components.
- Data Interpretation: The chromatograms generated are interpreted to determine the relative amounts of different glyceride forms present in the sample.
The results from this analysis help identify any deviations from expected compositions or potential issues with raw materials. For example, unexpected levels of free fatty acids could signal contamination or improper storage conditions during transportation.
By adhering to EN 14105, laboratories ensure that their methods are consistent and reproducible across multiple analyses. This standardization is essential for maintaining high-quality standards within the food industry and related sectors.
Quality and Reliability Assurance
Ensuring accuracy and reliability in glyceride composition analysis requires stringent quality control measures at every stage of the process. Our laboratory employs advanced chromatographic techniques, state-of-the-art equipment, and trained personnel to deliver precise results consistently.
- Instrument Calibration: All analytical instruments used for this service are regularly calibrated against certified reference materials (CRMs) provided by reputable organizations such as NIST or ISO. This ensures that all measurements align with internationally accepted standards.
- Analytical Reproducibility: To maintain high reproducibility, we follow standardized procedures outlined in EN 14105 for sample preparation and instrumental operation. These procedures minimize variability between different operators and laboratories performing the same analysis.
- Reference Material Usage: We use certified reference materials (CRMs) to calibrate our instruments and validate results. CRMs provide a known value against which actual measurements can be compared, ensuring accuracy down to parts per thousand.
- Data Validation: Each set of data is subjected to rigorous validation checks before being reported. This includes checking for outliers, assessing linearity, and comparing results with previous analyses where applicable.
In addition to these technical measures, our team adheres to best practices in laboratory management systems (LIMS), which helps track all aspects of the analytical process from sample receipt through final reporting. Regular internal audits ensure compliance with current standards and continuous improvement initiatives aimed at enhancing overall performance.
Our commitment to quality extends beyond just meeting EN 14105 requirements; we strive to exceed expectations by providing timely, accurate reports that are both reliable and actionable for our clients.
International Acceptance and Recognition
EN 14105 has gained widespread acceptance within the European Union (EU) as well as internationally due to its rigorous approach to ensuring consistent and accurate glyceride composition analysis. Many countries outside Europe have adopted this standard or similar ones because of its effectiveness in maintaining high-quality standards across various industries.
For instance, the United States Food and Drug Administration (FDA) recommends adherence to international standards like EN 14105 when evaluating imported foods containing significant amounts of fats or oils. Similarly, organizations such as the Codex Alimentarius Commission, which sets global food safety standards, reference EN 14105 in their guidelines for assessing the quality and authenticity of edible oils.
The growing trend towards sustainable sourcing practices has also highlighted the importance of reliable glyceride composition analysis. Consumers increasingly demand transparency about the origins and processing methods used in producing their favorite products. By complying with EN 14105, food companies can demonstrate their commitment to responsible production processes while simultaneously enhancing consumer trust.
Moreover, this standard supports traceability efforts by providing detailed information on each batch of oil processed through the supply chain. This level of detail is crucial for addressing concerns about potential contamination or adulteration during transit or storage.
In conclusion, adopting EN 14105 not only ensures compliance with regulatory requirements but also contributes positively to brand reputation and customer satisfaction. It serves as a benchmark against which other tests can be compared, ensuring consistency in quality assessment throughout the food industry.
