Fruits of persimmon (Diospyros kaki cv. Mopanshi) were used to investigate the effects of different concentrations of carbon dioxide (CO 2) gas on removing astringency after harvest. Treatment of 95% concentration of CO 2 gas gave the best results; fruits turned non-astringent after 20 h, and kept the fruit firm for 7 d at room temperature. Fruits, treated with 85 and 90% concentration of CO 2 gas, turned non-astringent after 2428 h, and the firmness-keeping stage was 56 d at room temperature. While the CO 2 gas was at 80, 70 and 60%, the de-astringency period was 48, 72 and 96 h, and the corresponding firmness-keeping stage was 3, 2 and 1 d, respectively. Fruits, treated with 50% concentration of CO 2 gas, remained astringent. Fruits of persimmon (Diospyros kaki cv.
