The respiratory characteristics and quality attributes of mature-green mume fruits as influenced by modified atmosphere packaging(MAP) conditions during storage at 25℃ for 8 days were investigated. The quality attributes of mume fruits were evaluated in terms of fresh weight loss, physiological injury and yellowing. The packaging materials used for MAP were low density polyethylene(LDPE) films with various different thicknesses. Yellowing and fresh weight loss of mume fruits were noticeably reduced by the packaging treatments with LDPE A and B. The physiological injury of the fruits during storage was found to be more severe in LDPE C than others. For LDPE A and B, the oxygen and carbon dioxide contents within the packages of Mume fruits maintained at the levels of 2~3% and 7~8%, respectively. With respect to visual quality, MAP prolonged the shelf life of the fruits much longer compared with the unsealed control. From the experimental results, it is suggested that the LDPE films with the gas transmission rates of about 2,100 O₂ml/㎡ㆍdayㆍatm and 6,700 CO₂ml/㎡ㆍdayㆍatm would be proper for MAP of mature-green mume fruits during storage at ambient temperature.
