경북지방에서 많이 생산되고 있는 생과용 복숭아를 이용하여 수확후 오존수 침지처리가 복숭아 품질신선도에 미치는 영향에 대하여 분석한 결과 가용성고형물은 처리후 일수가 경과할수록 조금씩 증가하는 경향을 보였으며, 처리후 15일째는 무처리구와 오존수처리구에서 유의적으로 차이가 나타나지 않았으며, 산도의 변화에서는 무처리구에 비해 오존수 침지처리가 저장기간이 경과할수록 낮아지는 경향을 보였는데, 오존수처리후 10일째와 15일깨 모두 처리구보다 낮게 나타
This study was conducted to enhance the quality and peach (Yumyung) by ozone treatment. The ozone concentration and treatment time in soaking of peach were 0.1, 0.3 and 0.5 ppm and 30 min respectively. Fruit brix degree, titratable acidity, hardness, colors values, and rotten rate were determined in ripening grade Yumyung peach and when fruits were placed at ambient temperuture(25) during 20 days. No great difference occured between control group and all ozone treatment samples in the changes of brix degree, titratable acidity, hardness and color values at my sampling period. However, the rotten rate of ozone-treated peach stored at 25 was lower than that of control sample. The orders of rotten rate in peaches stored for 15 days at 25 were control products > 0.1ppm ozone-treated > 0.3ppm ozone-treated) 0.5ppm ozone-treated. Therefore, optimal renditions of Yumyung peach stored by ozone treatment at ambient temperature during 20 days were ozone concentration of 0.5ppm, treatment time of 30min, and ozone treatment frequency of four times.
