The migration of the biocides: 2-methyl-2H-isothiazol-3-one (MIT), 1,2-benzisothiazol-3(2H)-one (BIT) and 2-phenoxyethanol (PHE) from spiked paperboard into the simulants Tenax, water and acetic acid (3%) has been studied and compared with that into the vegetables: red cabbage, lettuce and cauliflower. The migration of the biocides into the vegetables is significant and it shows the trend BIT > PHE > MIT, at both 4 °C and room temperature (RT), whatever tested foodstuff and with the highest value corresponding to BIT into cauliflower at RT (71%). Differences up to one order of magnitude between the biocides migration into Tenax (<4.3%) and that into the vegetables indicate that Tenax is not a suitable food simulant to mimic the selected vegetables in terms of the migration of the studied biocides. Water has been shown to be the most appropriate food simulant in the cases under study.
