Abstract.Respiration rates of freshly harvested cilantro were moderately high and ethylene production rates were low at 5 and were typical of green leafy tissues. cilantro stored in darkness at a range of temperatures in air or controlled atmospheres was evaluated periodically for visual quality, decay,aroma,off-odor ,color,and chlorophyll content.cilantro stored in air at 0 had good visual quality for 18 to 20 days,while at 5 and 7.5 good quality was maintained for about 14 and 7 days,respectively.an atmosphere of air plus 5% or 9% CO extended the shelf-life of cilantro stored at 7.5 to about 14 days.quality of cilantro stored in 3% O plus CO was similar to that stored in air plus CO atmospheres enriched with 9% to 10% CO caused dark lesions after 18 days;20% CO caused severe injury after 7 days. although visual quality could be maintained for up to 22 days,typical cilantro aroma decreased notably after 14 days,regardless of storage conditions.
