Abstract

ABSTRACT Gamma irradiation of red capsicums (cv. Five Star) at 75 and 300 Gy had no significant effects on the carotene level of unstored red capsicums or red capsicums stored at 5°C for 3 wk. Gamma irradiation of mangos (cv. Kensington Pride) at 75, 300 and 600 Gy had no significant effects on the carotene content. Altering the conditions of irradiation (lower temperature, nitrogen atmosphere, lower dose rate) resulted in slightly higher carotene levels than those associated with irradiation under normal ambient conditions.
