Abstract: The raspberry fruits were fumigated with different mass concentrations（0, 6.42, 12.84 and 19.26 mg/m~3） of ozone for 1 h and stored at（0±0.5） ℃ for 16 d, the effects of different mass concentrations of ozone treatments on the storage quality of raspberries were investigated. The results showed that, compared with the untreated control, ozone treatment could maintain good sensory quality of raspberry fruits, inhibit decay, delay the decline of fruit hardness,maintain higher soluble solids content, increase the brightness L^*and a^*values of fruit, and inhibit the rise of malondialdehyde content. In addition, the lower mass concentration of ozone treatment was beneficial to maintain the total phenolic content in raspberry fruits, and with 6.42 mg/m~3ozone fumigation treatment having the best preservation effect.
