Objective of this study was to develop the respiration model for edible coated minimally processed (ECMP) mango fruits. The assessment of the maximum rate of oxygen consumption (RO2 max) and the oxygen internal partial pressure at the half level of RO2 max, namely, k has been carried out for Arumanis mango. The SOP (Standard Operation Procedure) for the minimally processed, and the ECMP Arumanis mango have been established. The empirical models of RO2 max and k of the ECMP mango have been developed for various storage temperatures of 5-25 deg C for example, the RO2 max and k at 10 deg C are found out to be 74*10**(-8) mol/kg sec and 7.68 kPa, respectively. The quality changes of the ECMP mango during the storage have also been observed. The critical quality parameters are the yellowness and the hardness of mango which are influenced by the temperature and can be expressed in Arrhenius equations. The arrhenlus constants, found in the experiments, are 75.92*10**(4) k0 and 39.207 KJ/mol Ea for the changes in yellowness, and 10.53*10**(6) k0 and 43.922 KJ/mol Ea for the changes in hardness.
