Information on respiration rate of fruit in various temperatures and gas compositions is essential for designing the storage room. The present study aimed to develop respiration rate models of ‘Manalagi’ mango fruit under different temperature and oxygen concentration. Respiration rate was measured with a closed system respirometer at 10, 15 and 28°C of temperature and 3, 10, and 21% of oxygen concentrations. The observed data the used to develop mathematical model based on Michaelis-Menten (MM) with four types of inhibition and an Arrhenius equation. The results indicated that MM models were different for each treatment investigated, among them combination type had the most suitability, however there was no single model which appropriated for all treatments evaluated. Arrhenius equation could be used to describe the effect of temperature on the respiration rate satisfactorily. Three-way repeated measure of statistical analysis confirmed that there was no significant interaction among O 2 level, temperature, and measure time in both RO 2 and RCO 2 . However, temperature and O 2 concentration of the storage room gave significant effect in both respiration rates of RO 2 and RCO 2 .
