“…The higher migration observed into fatty food simulants could be also attributed to two factors: the higher solubility of migrated AOs into these solvents and the phenomenon of swelling of the polymer matrix when the films come into contact with simulants (Suppakul, Sonneveld, Bigger, & Miltz, 2011). Tehrany et al (Tehrany, Mouawad, & Desobry, 2007) indicated that migrant polarity can be a predominant controlling factor and that a simulant with similar high polarity could have a great effect on sorption. In this sense, partitioning depends on the polarity and solubility of the migrant in the food simulant.…”

13The migration of antioxidant (AO) agents, carvacrol and thymol, from polypropylene (PP) 14 packaging films containing the studied compounds at 80 g/kg separately and an equimolar 15 mixture of them into food simulants was investigated. Fast and reliable analytical procedures 16 were developed and validated for the analysis of the studied AOs in food simulants. For 17 aqueous food simulants, solid phase extraction followed by GC-MS analysis was performed. extending the shelf-life of food products.

“…Indeed, the partition coefficient of a series of compounds with the same functional group (i.e. esters or aldehydes) increased with increasing carbon chain length [21,[25][26][27][28][29][30]. The alcohols in aqueous solutions increase its partition coefficients to increasing its molecular weight.…”

Abstract. Polymeric materials have been extensively used in food packaging. The main problem associated to plastics is the migration of low molecular substances from the material to the food, which may be potentially dangerous for the consumers' health. The key parameters of the migration are the partition and diffusion coefficients. The development of polymer nanocomposites is expected to provide new materials with enhanced properties and safer food packaging. This work describes a procedure to determine the partition coefficients of selected model substances between low-density polyethylene (LDPE) and polyamide (PA) and, between LDPE and nanocomposite polyamide (naPA). The assays were conducted at different time-temperature conditions. The model migrants were extracted from the polymeric materials with ethanol and analyzed by RP-HPLC-DAD-FLD. The values of the partition coefficients obtained ranged from 0.01 to >1000. The results obtained suggest that the incorporation of nanocomposites could affect the solubility of certain compounds into the polymeric matrix.

“…Smaller molecules are absorbed more rapidly because they have a greater diffusivity than larger molecules. In fact, the partition coefficient of a series of compounds with the same functional group (i.e., esters or aldehydes) increased with increasing carbon chain length [5,[25][26][27][28][29][30]. The alcohols in aqueous solutions increase its partition coefficients to increase its molecular weight.…”

Studies on nanoparticles have focused the attention of the researchers because they can produce nanocomposites that exhibit unexpected hybrid properties. Polymeric materials are commonly used in food packaging, but from the standpoint of food safety, one of the main concerns on the use of these materials is the potential migration of low molecular substances from the packaging into the food. The key parameters of this phenomenon are the diffusion and partition coefficients. Studies on migration from food packaging with nanomaterials are very scarce. This study is focused on the determination of partition coefficients of different model migrants between the low-density polyethylene (LDPE) and polypropylene (PP) and between LDPE and nanocomposite polypropylene (naPP). The results show that the incorporation of nanoparticles in polypropylene increases the mass transport of model migrants from LDPE to naPP. This quantity of migrants absorbed into PP and naPP depends partially on the nature of the polymer and slightly on the chemical features of the migrant. Relation (RPP/naPP) between partition coefficientKLDPE/PPand partition coefficientKLDPE/naPPat 60°C and 80°C shows that only BHT at 60°C has aRPP/naPPless than 1. On the other hand, bisphenol A has the highestRPP/naPPwith approximately 50 times more.
