UV Ink Photoinitiators Migration to Food Simulants Behavior Using Spectroscopy

The migration behavior of UV ink photoinitiators from the substance of the food packaging to the food is simulated by photoinitiator spectrometry analysis. The different food simulants 10% ethanol, 95% ethanol and 97% isooctane migration behavior of the photoinitiators 1-Hydroxycyclohexyl phenyl ketone (184) are simulated on the polyethylene (PE) coated paper 4018,4025 and 4918 PE coated layer at different temperatures of 30°C, 45°C and 60°C. The qualitative and quantitative analysis is done using infrared spectroscopy and ultraviolet spectrophotometry. It is discussed that the effect of the temperature, swelling, PE lamination layer thickness as well as the paper thickness of pollutants by the different thickness of the polymer coating on the migration to food simulants.
