摘要: 以“黑宝石”李为试材,研究不同气体成分对果实品质及保鲜效果的影响。结果表明:“黑宝石”李的适宜气调贮藏条件为:O2体积分数≥2%,CO2体积分数≤5%。在此气体指标及0~1℃条件下,“黑宝石”李可贮藏3个月以上,出库时好果率在85%以上,腐烂率低于10%,果肉色泽、风味正常。在贮藏过程中,果实硬度和可滴定酸含量不断下降,果肉相对电导率不断升高,高氧和低二氧化碳处理加快了这些果实品质的变化,不同气体指标对可溶性固形物含量影响不大。

关键词: 黑宝石李, 气调贮藏, 果实品质

Abstract: Friar plum (Prunus salicina Lindl.) was used as the raw material to explore the effect of gas composition on fruit quality and preservation of fruits during modified atmosphere cold storage. The results showed that the optimal gas composition for the storage of Friar plum was composed of O2 ≥ 2% and CO2 ≤ 5%. Under the optimal gas conditions, the storage life of plum fruits at 0-1 ℃ exceeded 3 months. After the storage, fruit firmness and the contents of titratable acids in fruits were declined. The conductivity of pulp was increased when compared with pre-storage. The percentage of good fruits was higher than 85% and the rotting rate was less than 10%. In addition, the color and flavor of fruits were normal. 

Key words: Friar Prunus salicina, controlled atmosphere storage, fruit quality
