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
