摘要:
The liquid smoke flavour UTP‐1 was spiked with polycyclic aromatic hydrocarbons (PAHs) at a level of total concentration 45.6μg/kg and filled into bottles made of low‐density polyethylene. The concentration of PAHs was followed for 14 days. During this time the concentration of PAHs dropped roughly by two orders—from 45.6/μg/kg to 0·73μg/kg, when an inverse dependence between PAHs concentration and time of storage was observed. As demonstrated in the experiment, the lowering of PAHs concentration in the liquid smoke flavour UTP‐1 was due to the sorption of PAHs on packaging material, in which PAHs were found at the end of the experiment.
