Summary

AN INSTRUMENT TO MEASURETHE RESPIRATION RATE (RR) OF FRUITS AND VEGETABLES WAS DEVELOPED USING A PRESSURE VARIATION METHOD. A PRESSURE TRANSDUCER WAS USED TO MONITOR PRESSURE CHANGES DUE TO RESPIRATORY ACTIVITY. THE OPERATING PROCEDURES AND CALCULATIONS REQUIRED TO DETERMINE RESPIRATION RATE 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 WERE COMPARED TO CHANGES IN CO2 AND O2 CONCENTRATIONS AS DETERMINED BY GAS CHROMATOGRAPHY. THE RESULTS SHOWED NO SIGNIFICANT DIFFERENCE BETWEEN THE 2 METHODS.
