Abstract
Abstract Controlled atmosphere (CA) conditions were assessed for long-term broccoli ( Brassica oleracea L. Italica Group) storage. Broccoli was stored for 6 weeks at 1C under N 2 containing the following percentages of CO 2 /O 2 : 0%/20%; 10%/20%; 6%/2.5%; I0%/2.5%; and 15%/2.5%. Color and chlorophyll retention was better under CA than in air. This improved retention was mainly due to increased CO 2 concentration. Storage under CA also delayed the development of soft rot and mold. However, after 6 weeks of storage under an atmosphere containing 10% or more CO 2 , the rate of respiration increased simultaneously with the development of undesirable odors and physiological injury. Among the atmospheres tested, 6% CO 2 and 2.5% O 2 was the best for long-term (>3 weeks) maintenance of broccoli quality while avoiding physiological injury.
