  Abstract

CA storage is being used as a long-term storage technology to reduce the distribution loss rate of agricultural products and to control supply and demand. In particular, DCA research to minimize storage disorder is active. In this study, CA storage environment was observed using airtight chamber and automatic gas control algorithm using respiratory quotient was proposed. As a result, the airtightness for maintaining low oxygen concentration of less than 1% was required to be less than 0.25 (mmAq/min). The oxygen and carbon dioxide concentration were measured to calculate the respiratory quotient, and the anaerobic compensation point using the respiratory quotient and ethanol showed a difference of about 9 days. The gas change measurement points considering gas control characteristics were classified into four types. The respiratory quotient calculation and oxygen control algorithm were designed based on measurement point of four types. The respiration quotient was calculated between 0.5-1.7 using the designed algorithm. In order to control DCA using the respiratory quotient, it is necessary to improve sensor precision, uniformize the gas environment in CA storage, and study on the physiological properties of agricultural products according to the gas environment.
