수확 후에 실시되는 고 이산화탄소(60및 )의 전처리(3, 6, 12시간)가 '일천백봉' 복숭아의 상온 유통 중 신선도 및 부패에 미치는 영향을 조사하였다. 이상의 이산화탄소를 6시간 이상 전처리할 경우 상온 유통 중 호흡, 에틸렌 발생, 과피 변색 및 연화 현상이 둔화되었으며 유통기한 중 조직감이 향상되었다. 상온에서의 부패 현상도 및 를 6시간 이상 처리함으로써 크게 억제시킬 수 있었다. 복숭아과실의 가용성 고형분 함량은상온 유통중 변화하

This study was conducted to evaluate the efficacy of high a)z pre-treatment (60, for 3, 6, 12 hr) on quality of 'Hikawa Hakuho' peach fruits. High a)z treatment inhibited the respiration and ethylene production, especially with long tenn treatment for more than 6 hr. Discoloration of peel, softening and decay were reduced by high treatment concentration of did not affect soluble solids content and titratable acidity of fruits. treated fruits, however, showed higher sweetness score compared with control. As the concentration and treatment duration increased from 60 to and from 3 to 12 hr, respectively, the efficacy on quality increased. Fruits treated with for 3 hr and for 12 hr, however, showed very low flavor score due to the residual in flesh. High injury was not noted at any levels tested in this study. Above results suggest that treatment for 6 hr resulted in as good control of respiration, ethylene production, decay, discoloration and softening without off-order.
