Abstract
This study was carried out for improvement and correction of the traditional pressure variation method (PVM) in the respiration rate measurements of fresh fruits and vegetables using a microcomputer system and a differential pressure sensor. Water vapor pressure in the container was calculated by equations for psychrometric calculations. At the beginning of experimental period water vapor pressure in the container was increased and maintained constantly in the most experimental period, but was decreased dramatically after
과채류의 수파 후 저장에 있어서 중요한 생리적 지표가 되는 호흡속도를 마이크로컴퓨터와 압력센서 (MPX-10-DP, Motorola)를 사용하여 종래의 마노메타법의 문제점인 수증기압을 보정하여 간편하고 신속하게 측정할 수 있는 방법에 관해 연구하였다. 과채류 호흡속도 계측 중 각 온도구간에서 호흡속도 계측용기 내의 온도 변화는
