Taste interaction of styrene/ethylbenzene mixtures in an oil-in-water emulsion

Taste interaction of styrene/ethylbenzene mixtures in an oil-in-water emulsion

Food Additives and Contaminants 12(2): 203-209

Styrene and ethylbenzene are present in detectable amounts in polystyrene packaging materials and migration of these compounds may cause a taint of the packed food. The effect of mixtures of styrene and ethylbenzene on the detection threshold concentration in a 5% oil-in-water emulsion was investigated with the constant stimulus differences test. The detection threshold concentrations of the individual compounds in the emulsion were found to be 1.0 ppm for styrene and 3.0 ppm for ethylbenzene. Linear regression of the percentages of correct answers and the logarithm of the sum of the concentrations of both compounds in the mixtures expressed as fractions of their threshold concentration gave the following relationship: % of correct answers = 42.5 x log (sum of threshold fractions) +74.8 (r = 0.87). Calculation of the sum of threshold fractions at the 75% point of correct answers gave a value of 1.0, which clearly indicates that the effect of mixing of styrene and ethylbenzene is additive at sub-threshold levels in a 5% oil-in-water emulsion.
