For the purpose of the construction of the system which automatically searches the optimum gas composition for controlled atmosphere storage and modified atmosphere packaging, a computer-based respiratory property measurement and control system was produced experimentally. The calculation formulae of oxygen consumption rate, carbon dioxide evolution rate, respiratory quotient were deduced, and the measuring method of the gas-transfer coefficient necessary for the calculation of these respiratory properties was shown. As the result that this system was applied to broccoli and respiratory properties under three atmospheric conditions were measured, the oxygen consumption rate was suppressed mainly by the decrease in oxygen concentration, and the depression of carbon dioxide evolution rate by the increase in carbon dioxide concentration was observed.
