Summary

The effects of 0.5 and 1.0 kGy gamma irradiation on microbial and sensory characteristics of diced celery were compared to conventional treatments such as acidification, blanching, and chlorination. Aerobic plate counts for the irradiated celery did not exceed 10,000,000 CFU/g, in contrast the acidified, blanched, chlorinated, and control samples surpassed aerobic microbial counts of 100,000,000 CFU/g in 22, 19, 12, and 8 days, respectively. The 1.0-kGy treatment eliminated inoculated Listeria monocytogenes and E. coli. The irradiated samples maintained their color, texture, and aroma longer and were preferred in the sensory test. The sensory shelf life of the 1.0-kGy-treated celery was 29 days compared to 22 days for the control, chlorinated, and 0.5 kGy, and 15 d for the acidified and blanched celery.
