The impact of gamma irradiation on aroma, appearance, nutritional, textural, and microbiological quality attributes of fresh cilantro (Coriandrum sativum L.) was investigated. Irradiation at doses up to 2 kGy did not significantly influence aroma, amount of total volatile compounds, color or overall visual quality. Although firmness of cilantro was reduced by irradiation at day 0, there was no significant difference among treatments after 3, 7 and 14 days of storage at 3 degrees C. Irradiation did not have a consistent effect on antioxidant power or phenolic content during the 14-day storage. In contrast, vitamin C content was lower at day 14 in samples irradiated at 2 and 3 kGy. Cilantro irradiated at 3 kGy had higher decay rate and off-odor scores than other samples after 14 days of storage. The total aerobic plate count of irradiated cilantro was significantly lower than that of nonirradiated controls immediately after irradiation and during the entire storage period. Our results suggest that fresh cilantro irradiated at 2 kGy retained its sensorial quality and shelf life.
