THE DETERMINATION OF THE SUITABILITY OF ALUMINUM CONTAINERS FOR THE PACKAGING OF IRRADIATED FOODS. Report No. 6 (Final), November 29, 1958-July 28, 1961
Five food products, whole kernel corn, green beans, phosphate cured ham, tuna chunks, and peaches were packed in aluminum and tinplate cans, irradiated to a dosage level of 5.0 megarads, and stored for one year at 77 and 100 deg F. Samples from the same lots of cans were thermal processed as controls. All enameled aluminum containers performed satisfactorily with the five foods 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. The tinplate variables performed satisfactorily for all but ham when irradiated or thermal processed. In the case of ha:m packed in enameled tinplate cans, the irradiated samples were satisfactory while the thermal proc essed cans showed some loss of enamel, adhesion peeling, blisters, and corrosion at the drawn corners of the cans. Irradiation caused considerable hydrogen formation in all the products as determined by headspace gas analyses. (P.C.H.)
