Safety assessment of antimicrobials in food packaging paper based on LC-MS method

Many difficulties relating to food safety have been solved thanks to the employment of strong mass spectrometric detectors in conjunction with liquid chromatography. In this study, samples were fractionated using gel permeation chromatography and liquid/liquid extraction, and liquid chromatography/mass spectrometry (LC/MS) and gas chromatography/mass spectrometry were used to detect possible genotoxicant(s) in recycled paperboard. As a genotoxicity indicator, the rec-assay was utilized. Abietic acid (AA) and dehydroabietic acid (DHA) and were discovered in the recycled paperboard to be genotoxic. AA and DHA were found in 2 of 5 virgin products and all seven recycled food-contact products. AA and DHA total levels in virgin goods were 990 and 240 mg/g, respectively, whereas recycled products had 200990 mg/g. The total quantity of AA and DHA content in DNA-damaging activity and paper products were shown to have a strong connection. Furthermore, genotoxic effects in paper products matched standard chemicals well, showing that AA and DHA were primarily responsible for the genotoxic effects of these paper products.
