Abstract
Respiration characteristics and quality changes in broccoli as affected by high CO2 treatment was investigated. Broccoli florets were exposed to high CO2 (≒ 100%) for 0, 3, 6 and 10 h at room temperature (about 26℃) and then stored at room temperature. The respiration and ethylene productions were decreased remarkably by all treatments except control treatment during storage period. Ascorbic acid content in broccolis florets exposed to high CO2 was decreased rapidly compared to that in control treatment. After 2 days of storage, yellowing appeared rapidly in the control and in the 3 h high CO2 treatments. However, yellowing was inhibited remarkably in 6 and 10 h treatments. The chlorophyll content was the highest in broccoli florets exposed to 100% CO2 for 6 h. As a results of sensory test such as discoloration, wilting, texture, decay and off-flavour, the market quality remained 2 days in control and 3 h treatments and it extended up to 4 days in 6 and 10 h treatments. But off-flavour was observed in broccoli florets exposed for 10 h to 100% CO2.
