Effects of deodorization on the content of polycyclic aromatic hydrocarbons (PAHs), 3-monochloropropane-1,2-diol esters (3-MCPDE) and glycidyl esters (GE) in rapeseed oil using ethanol steam distillation at low temperature

•Ethanol steam distillation reduces harmful substances in oil.•PAHs removal is more efficient by using ethanol steam.•Less formation of 3-MCPDE and GE via ethanol steam distillation.•Simultaneously removing PAHs and inhibiting 3-MCPDE and GE at low-temperature. High temperature is beneficial for the...
