Abstract: Freshly harvested Big Five-pointed Star loquat fruits were pre-cooled on the same day and then stored at 3 ℃ and 75%-85% humidity for 30 days. During the storage period, the loquat fruits were treated with ozone for 30 min once a week and sampled every 4 days for the determination for various physiochemical and physiological characteristics. Ozone treatment at the concentration of 100 mg/m3 had some fresh-keeping effect on Big Five-pointed Star loquat fruits. The best fresh-keeping effect was observed by using 150 mg/m3 ozone treatment. Ozone treatment could damage Big Five-pointed Star loquat fruits at the higher concentration of 200 mg/m3.

Key words: Big Five-pointed Star loquat fruits, ozone treatment, preservation
