Vegetable crisps are usually perceived to be a healthier alternative to potato crisps, though thermal treatment can generate harmfull contaminants such as monochloropropanediol and glycidol fatty acid esters (MCPDEs and GEs) or acrylamide in these products. This study is among the first to investigate MCPDE, GEs, and acrylamide in commercial potato, sweet potato, parsnip, beetroot, and carrot crisps. These contaminants were found in all crisp samples on the market. The novel alternative vegetable crisps (n=16) showed substasntial higher concentrations than in traditional potato crisps (n=29), e.g. beetroot crisps had 7 times higher amount of 3-MCPDEs (mean 212 μg/kg), while acrylamide was 8 times higher in carrot crisps (mean 2893 μg/kg) and ~3-4 times higher in beetroot, parsnip and sweet potato crisps. All vegetable crisp had mean values of acrylamide higher than European Commission established benchmark level for potato crisps at 750 μg/kg. Consequently, risk assessment demonstrated concerning Margin of Exposure...
