The effect of irradiation on several canned pork products was studied. Fresh, ground ham patties were freezedehydrated to 1% moisture. A portion of these patties were then rehydrated to 7% and 50% moisture. Canned patties were irradiated at 1, 2, and 4 megarads and evaluated for irradiation flavor. The results indicated that the intensity of irradiation flavor incrcased with increased dosage in the 50% moisture samples only. No significant destruction of thiamine was found in fresh, ground ham patties, freezedehydrated to 1% moisture and irradiated 0, 1, 2.5, and 4.5 megarads; on the other hand, a characteristic destruction pattern of thiamine was observed in both the fresh control and completely rehydrated samples. About one third of the initial thiamine content was destroyed by the freezedehydration process. Fresh, ground ham was mixed with cured, canned, cooked, and irradiated at 0, 3.7, and 5.6 megarads. An untrained taste panel indicated no significant flavor preference for the non-irradiated control over the irradiated samples. A storage test showed that the shelf life of the control sample was considerably shorter than that of the irradiated samples. Pork bellies were cured and smoked, one for 12 hours and the other for 24 hours, then sliced, canned, and irradiated at 4.5 megarads. No undesirable flavors and no destruction of smoke flavor due to irradiation were detected. Additional post-irradiation storage test coupled with flavor evaluation indicated a preference for the less smoked bacon. Storage temperatures did not affect the product quality. (auth)
