Abstract

Plastic materials intended for contact with food sometimes exhibit unfavorable organoleptic properties which is related to the presence of volatile organic compounds. These substances not only worsen organoleptic properties, but can be very harmful to humans health. For the sake of consumer safety, it is necessary to control such materials for the content of substances harmful to health, as well as the possibility of their migration to food. Therefore, there is a need to have an appropriate and verified analytical method that could be used in the routine analysis of volatile organic substances present in food contact materials. In this study, the possibilities of the application of HS-GC/MS and SPME-GC/MS analytical techniques for analyses of volatile organic compounds present in polystyrene food contact materials, demonstrating disadvantageous organoleptic properties were evaluated. On the basis of sensory tests four types of food contact materials (plastic dishes) were selected for the study. The analytical measurement was performed by HS-GC/MS and SPME-GC/MS techniques parallel. In quality examinations of samples the aliphatic and aromatic, saturated and unsaturated hydrocarbons, as well as other compounds, e.g. ketones cont...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
