Polycyclic aromatic hydrocarbons (PAH) and phenolic substances in meat products smoked with different types of wood and smoking spices

“…Carbon-based surfaces widely exist in both nanoscale and macroscopic materials, and most of them contain π electron-rich structures which is a hexagonal carbon ring where there are rich π electrons, such as aromatic rings in biomolecules1, humus in the soil23, polycyclic aromatic hydrocarbons in air pollutants456, and graphene78, carbon nanotubes910, and fullerenes11. It has been widely reported that the accumulation of ions at carbon-based surfaces greatly impacts the properties and applications of carbon-based materials, including surface- or interface-charged behaviors12131415, aqueous suspension and aggregation1617, surface modification1819, chemical synthesis2021, and the function, configuration, and stability of biological systems222324.…”

By incorporating cation-π interactions to classic all-atoms force fields, we show that there is a clear enrichment of Na+ on a carbon-based π electron-rich surface in NaCl solutions using molecular dynamics simulations. Interestingly, Cl− is also enriched to some extend on the surface due to the electrostatic interaction between Na+ and Cl−, although the hydrated Cl−-π interaction is weak. The difference of the numbers of Na+ and Cl− accumulated at the interface leads to a significant negatively charged behavior in the solution, especially in nanoscale systems. Moreover, we find that the accumulation of the cations at the interfaces is universal since other cations (Li+, K+, Mg2+, Ca2+, Fe2+, Co2+, Cu2+, Cd2+, Cr2+, and Pb2+) have similar adsorption behaviors. For comparison, as in usual force field without the proper consideration of cation-π interactions, the ions near the surfaces have a similar density of ions in the solution.

High consumption of meat was shown to be positively associated with increased risk of some types of cancer. Meat could be involved in carcinogenesis via carcinogenic substances related to cooking and processing, e.g. nitrate, heterocyclic amines, polycyclic aromatic hydrocarbons. The evaluation of exposure to carcinogens from the diet is estimated using food frequency questionnaire and instrumental analysis. However, there is a lack of methods suitable to use by individual consumer enabling individual dietary hazards assessment. The purpose of this paper was to introduce the fast estimation method of dietary exposure risk to cooked meat-related carcinogenic substances, which could be easy to use by individual consumer. The method was based on special, formula which includes factors related to meat processing and cooking involved in carcinogens formation. It allows to calculate the hazard category and shows cooking procedures which lower the risk. The method may be helpful for every family to reduce intake of meat-related carcinogenic compounds, thus decreasing the risk of cancer.
