CA저장에 적합한 떫은감 품종을 선발하기 위해 청도반시, 사곡시, 고종시, 봉옥시 4품종을 공시하여 농도를 12, 16%로 하였으며 농도는 같이 3%로 하여서 약 160일간 저장하여 품질변화를 조사한 결과는 다음과 같다. 가용성 고형분 함량은 저장기간이 경과함에 따라 거의 변화가 없거나 감소하였으며, 청도반시, 사곡시, 고종시는 12%, 16% 모두 일반 저온저장고와 비슷한 수준이었으나, 봉옥시는 고농도의 로 가용성 고형분의 감소가 현저하였다.

Four cultivar of astringent persimmon(Diospyros kaki L. Cheongdobansi, Sagkoksi, Gojongsi, and Hachiya) were evaluated for quality during 160 days storage in condition of air, 12%CO+3%CO, and 16%CO+ 3%COat 0∼2. In the fruits of Cheongdobansi, Sagkoksi, and Gojongsi cultivar, the soluble solids content did not change significantly during storage among treatment, but in the fruits of Hachiya cultivar it decreased during storage in the codition of high COconcentration. Fruits of Cheongdobansi and Sagkoksi, which were stored in higher COconcentration, had firmer hardness, less weight loss and decay, showed greater rentention of initial peel color, maintained best qulity than air-stored fruit, but had high tannin contents. And it was necessory to remove astringency for edible fruits.
