Meaning
Standardised liquid used to represent fatty foodstuffs during migration testing of plastic packaging. Vegetable oil simulant d2 mimics the extraction potential of edible oils and fats when they come into contact with polymer surfaces. Testing ends once the required duration at a specific temperature is completed.
Fat Mimicry
Compatibility of the simulant with non-polar additives ensures that the test reflects the real-world leaching of chemicals. Vegetable oil simulant d2 is often composed of refined sunflower oil or a synthetic mixture of triglycerides. It provides a realistic medium for assessing the transfer of antioxidants and lubricants into fatty foods.
Temperature Tolerance
Stability of the oil during long-term storage tests is necessary to maintain the accuracy of the migration data. Vegetable oil simulant d2 can be used at temperatures up to one hundred degrees celsius to simulate hot-fill or microwave applications. Maintaining the purity of the oil is essential to prevent interference with the chromatographic analysis.
Regulatory Comparison
Acceptance of the results by food safety agencies depends on the use of approved simulants and standardized protocols. Vegetable oil simulant d2 is the benchmark against which alternative solvents like iso-octane are compared. If the migration into the oil exceeds the legal limit, the packaging must be redesigned to include a better barrier layer.
The simulant is the primary medium for verifying the safety of plastics used in the dairy and meat industries.
