The quality characteristics of ‘Xiangshui’ pears (Pyrus ussuriensis) treated with different concentrations of biomass pyrolysis liquid (BPL) during storage at 25℃ were investigated. The weight of ‘Xiangshui’ pears treated with BPL declined at a slower rate than that of the control. The rot index of BPL-treated ‘Xiangshui’ pears decreased with increasing storage times, and treatment with 20-fold-diluted BPL resulted in the lowest rot index after storage for 12 days. The total acid content of ‘Xiangshui’ pears treated with 20-fold-diluted BPL was 0.19%, and was the highest after storage for 12 days. After storage for 12 days, the total sugar content of ‘Xiangshui’ pears treated with 20-fold-diluted BPL was 7.19%; this was significantly higher than that of the control, but not significantly different from that of pears treated with other BPL dilutions. The vitamin C content of ‘Xiangshui’ pears showed a decreased trend, and pears treated with 20-fold-diluted BPL had a vitamin C content of 2.21 mg/100 g after storage for 12 days and showed the least decline compared to other treatments. In addition, respiration in ‘Xiangshui’ pears was effectively inhibited by treatment with BPL. In conclusion, BPL treatment exerts a protective effect on the quality of ‘Xiangshui’ pears during storage, with 20-fold-diluted BPL being the most effective.
