Physicochemical Properties of Chemical Pollutants Available in Food Contact Materials (FCM)

Abstract

Health and welfare of population are priority reasons to study the toxic effects of chemical pollutants. These effects can directly produce deterioration of health or can cause less healthful environment toxicity and restricting food production. Thereby, preventing such a consequence is important for human health risk assessment. In recent times, the use of recycled materials for packaging has undeniably been intensified. Nevertheless, recycling systems could not effectively eliminate the potential effect of chemical pollutants (alkyl phenol, phthalates, aldehydes, etc.) existent in such packages. The migration process and/or the ability of these pollutants to be absorbed into the recycled material, subsequently released by the packaging material, and then trapped by the matrices they contain, has become a potential source of exposure to consumers. This process is controlled by the nature of the packaging, time, temperature, and the physicochemical properties of the contaminant. The literature suffers from a lack of data related to the physicochemical (aqueous solubility, vapor pressure, Henry’s constant, etc...) of these contaminants. In this work, we are going to describe the experimental devices used for aqueous solubility, vapor pressure and octanol/water partition coefficient determination.

Migración Química Desde Envases Fabricados Con Polipropileno Hacia Alimentos Grasos

“…Se manifiesta con la transferencia de masa desde el alimento hacia los envases; ocasionando la perdida de aditivos o sustancias que contiene un producto y que son esenciales para su conservación; es decir, cuando el empaque se expone a olores indeseables, o cuando el olor deseable propio del producto empacado se pierde por la permeación del empaque (Farhat et al, 2019); (Arvanitoyannis y Bosnea, 2004).…”
