“…competed with BaP, and affected the rate of BaP diffusion in the oils and extent of adsorption onto PET. For these reasons, the final state of PAH-PET interactions could be classified such as the surface adsorption [53], what limits considerably the PET capacity in removal processes of PAHs from liquid media.…”

This review deals with effects of environmental and physicochemical factors affecting polyaromatic hydrocarbon (PAH) elimination from smoked meat products and liquid smoke flavoring (LSF). In the introductory part, some essential information are aimed at principles of food smoking and PAH formation during smoke generation as a result of incomplete wood combustion. Also, an application of alternative technology for food aromatization using LSF is briefly mentioned. Similarly, latest European legislation, biological effects, and analytical aspects of PAHs are mentioned concisely. The main part is devoted to physicochemical factors affecting the PAH content in smoked meat products, such as light, additional cooking, and packaging, which are able to decrease considerably PAH content in some meat products. The most important effect on PAH concentration decrease in LSF has low-density polyethylene (LDPE) package due to sorption processes on a surface of the plastic with subsequent diffusion into the plastic bulk. A less effective material is polyethylene terephthalate (PET), when only a surface adsorption process comes into account. Moreover, this process is affected also by other compounds presented in liquid media able to compete for the adsorption center on the PET surface.

“…which gives rise to almost a pure triacylglycerol mixture formation. The removal of these compounds from rapeseed oil increased the equilibrium coefficient as shown in Table 1 ( ŠIMKO et al 2005). However, the distillation of sunflower oil brought about a considerable decrement of the equilibrium coefficient although the diffusion coefficient had an almost identical value.…”

“…This assumption can be supported by the great similarity of the diffusion coefficient values for both sunflower oils (Table 1), which evokes that the main part of BaP interacted with π-electron pairs of linoleic acid, and that only a minor part of BaP interacted with PET. Overall, this "double behaviour" of BaP ŠIMKO et al (2005) resulted in the lowered efficiency of the processes of BaP removal from distilled sunflower oil. Because the removal of BaP is limited by the surface adsorption and the diffusion of BaP into LDPE bulk had been already proven, LDPE was studied for BaP removal from the oil.…”

AbstractŠIMKO P., SKLÁRŠOVÁ B., ŠIMON P., BELAJOVÁ E. (2006): Effect of plastic packages on benzo[a]pyrene concentration in sunflower oil. Czech J. Food Sci., 24: 143-148.Commercially available sunflower oil and the same oil distilled additionally in a molecular evaporator (to remove naturally occurring compounds) was spiked with benzo[a]pyrene (BaP) at the levels of 37.1 and 38.6 µg/kg, respectively. Then, it was filled into polyethylene terephtalate (PET) and low density polyethylene (LDPE) receptacles of cylindrical shape, and BaP concentration was followed within 49 h. At the end of the experiments, BaP concentration in the non-distilled oil packed into PET decreased to 25.9 µg/kg, and BaP concentration in the distilled oil decreased to 34.6 µg/kg. The rate and the extent of BaP removal were evaluated comparing the diffusion and equilibrium coefficients. The results showed that PET is able to reduce BaP concentration in sunflower oil due to BaP sorption on the PET surface, but the rate and the extent of BaP removal are also affected by other compounds present in the oil. As found, LDPE is an inappropriate material for the BaP removal from sunflower and rapeseed oils, because BaP concentration in the oils remained at a constant level during the whole experiment.
