Controlled Atmosphere and Subsequent Air Storage of Broccoli Florets at Various Temperatures

抄録

The physiology and quality of ‘Greenbelt’ broccoli florets (Brassica oleracea L. italica) were monitored during CA storage in 0.5% O₂ and 10% CO₂ at 0 and 5°C and in 1% O₂ and 10% CO₂ at 10°C and subsequent air storage at the same temperature. The CA reduced respiration, weight loss, and decay at all temperatures, yellowing and L-ascorbic acid loss at 5 and 10°C, and ethylene production and microbial growth at 10°C. Upon transfer of the florets to air following CA storage for 4, 3, and 1 weeks at 0, 5, and 10°C, respectively, respiration rate increased initially and then remained constant. Ethylene production continually increased. Decay, microbial count, odor, color, and L-ascorbic acid content remained essentially unchanged for a few days after the samples were transferred to air regardless of temperature.
