ISO 18363-1 Glycidyl Esters in Edible Oils
In the context of food and feed testing, particularly within the realm of fatty acid and lipid profile analysis, one of the critical parameters is the presence of glycidyl esters. ISO 18363-1 provides a standardized method for determining the content of glycidyl esters in edible oils. This service ensures that producers, processors, and quality managers can meet regulatory requirements and maintain product safety and integrity.
Glycidyl esters are an unwanted by-product formed during the hydrogenation process used to extend the shelf life of fats and oils. Excessive levels can pose health risks, especially when consumed in large quantities over time. This testing service helps ensure that food products comply with international safety standards, thereby protecting consumers from potential adverse effects.
The methodology outlined by ISO 18363-1 involves several steps to accurately measure glycidyl esters. The process begins with the preparation of a sample, which typically requires the oil to be filtered and diluted as per specified ratios. This ensures that the sample is representative of the product being tested.
The test apparatus includes precise analytical equipment such as gas chromatographs equipped with mass selective detectors (GC-MSD). These instruments are capable of detecting even trace amounts of glycidyl esters, ensuring accurate and reliable results. The use of standardized methods guarantees consistency across different laboratories, enhancing the credibility of the test outcomes.
After sample preparation, the analysis proceeds by injecting the diluted oil into the GC-MSD system. This allows for the separation and identification of individual components within the sample, focusing specifically on glycidyl esters. The retention times and mass spectra obtained from this process provide a quantitative measure of the concentration of glycidyl esters in the edible oil.
The results are then interpreted against the acceptance criteria specified by ISO 18363-1. Compliance with these standards ensures that the product meets safety requirements, thereby safeguarding public health. For example, compliance can prevent the distribution of potentially harmful products to consumers.
This service is particularly valuable for quality managers and R&D engineers who need to ensure their processes align with international safety guidelines. By adhering to ISO 18363-1, companies not only meet regulatory requirements but also enhance consumer confidence in their products.
