Abstract
Analysis of blue cheese and blue cheese dressing for PR imine and PRT, metabolites of Penicillium roqueforti was performed by reversed-phase d high-performance liquid chromatography. PR imine was found in 50 of 60 samples of cheese in amounts ranging approximately 19 to 42 mug/kg of cheese, while PRT was not detected. Analysis of blue cheese dressin g showed no evidence of PR imine or PRT. Furthermore, the conversion o f PR imine to PRT in the presence of bovine serum (in vitro) was demon strated.
