Abstract

In order to prepare allowable guidelines for weight loss for packed agricultural produces during distribution after harvest, resipration and transpiration rates were investigated for fruits such as peach, apple, pear, persimon and mandarin which produced in Korea. Respiration and transpiration rates were widely different from cultivar and harvesting season among same produces. Respiration rates were increased as an environmental temperature was increased. Moisture amount that produced by respiration in five fruits was 3.55∼107.67mg/kg/h and those moisture amounts were considered as no much influence for the strength of cartons for packing of fruits. Moisture amount produced from transpiration was 24 ∼ 1,195g for 15kg packing unit of fruits in 5 days. after harvest.

국내에서 생산, 유통되는 주요 과일류인 복숭아, 사과, 배, 단감, 글에 대하여 환경 조건별, 품종별 호흡속도와 증산속도를 분석함으로서 유통중 객관적인 포장 농산물의 감모율의 허용기준 근거를 마련하고자 하였다. 신선 과일류의 호흡특성과 증산특성은 동일 품목이라도 품종과 수확시기에 따라 다르게 나타났다. 과일류의 호흡속도는 온도가 높을수록 높게 나타났으며 호흡작용의 과 발생되는 수증기 발생량은 3.55∼107.67mg/kg/h로 골판지 박스의 강도 저하에 영향을 미칠 정도로 높지는 않았다. 증산작용 결과 발생되는 수증기의양은 15kg 포장의 경우 5일후 24∼l,195g으로 호흡속도에 의해 발생한 수증기 양에 비해 훨씬 높게 나타났다.
