Abstract: | An instrument to measure the respiration rate of whole fruits and vegetables was designed and developed using a pressure variation method. The Motorola MPX-10-DP pressure transducer was used to monitor pressure changes due to respiratory activity. The operating procedures and calculations required to determine respiration rate (RR) in terms of CO2 produced, RR-CO2, and O2 consumed, RR-O2, with the respirometer were simple. The values of RR-CO2 and RR-O2 obtained by the pressure variation method were compared to changes in CO2 and O2 concentrations as determined by gas chromatography. The results showed no significant difference (0.05 level) between the two methods. |
