Title:

Abstract:
Five different food products, whole kernel corn, green beans, phosphate cured ham, tuna chunks, and peaches, have been packed in aluminum and tinplate cans, irradiated to dosage level of 5.0 megarads, and stored for one year at 77 and 100 F. Samples from the same lots of cans were thermal processed as controls. All enameled aluminum containers performed satisfactorily with corn, green beans, ham, tuna, and peaches when irradiated or thermal processed. The irradiation treatment appeared to have less effect on the enamels as measured by a lesser amount of darkening and staining and fewer micro-blisters as compared to the thermal process treatment. Plain aluminum containers performed satisfactorily with corn but unsatisfactorily with green beans, tuna, ham and peaches when processed either by irradiation or thermal treatment, due to excessive corrosion and staining of the plate. The tinplate variables performed satisfactorily for peaches, corn, tuna and green beans when irradiated or thermal processed. In the case of ham packed in enameled tinplate cans, the irradiated samples were satisfactory while the thermal processed cans showed some loss of enamel adhesion peeling, blisters and corrosion at the drawn corners of the cans. The product appearance varied from product to product in comparing irradiated samples with thermal processed samples. Corn, green beans and peaches were darker when irradiated as compared to the thermal processed products, while the reverse was true for ham and tuna.
