Effect of low-dose irradiation on biogenic amines formation in vacuum-packed trout flesh (Oncorhynchus mykiss)

► The formation of biogenic amines in trout fillets at 3.5 °C treated with radiation was studied. ► The doses of radiation were: 0.25, 0.50, 0.75, 1.0 and 2.0 kGy. ► Putrescine, cadaverine and tyramine showed good correspondence with the irradiation dose. ► Samples of good quality contained less than 10 mg/kg of each of these amines. ► For meat preservation purposes, the doses exceeding 1.0 kGy seem to be redundant.
