A respiration rate analysed by enzyme kinetics-based respiration model and gas permeability data of LDPE film were applied to design the optical modified atmosphere (MA) packaging condition of persimmon (Diospyros kaki cv. Fuyu) fruits. The fruit quality rapidly decreases due to physiology disorder such as softening and peel blackening. O2 permeance (QO2 in mlㆍhr−1ㆍatm−1ㆍm−2) and CO2 permeance (QCO2 in mlㆍhr−1ㆍatm−1ㆍm−2) of low density polyethylene (LDPE) film samples were measured at 0oC and described as function of thickness (L in μm) as QO2 = (2540×1/L)-16, and QCO2 = (13742×1/L)-70, respectively. MA package containing single persimmon fruit of 225g was designed and tested experimentally at 0oC by using LDPE films. Package atmospheres predicted from the relationship of O2, CO2 and N2 balances on the packages was in good agreement with those obtained experimentally. Physiology disorder occurrence was the lowest at 52 μm package that attained optimum gas condition (O2 2.8% and CO2 5.4%). The computer simulation was found to be effective to help to design the optimum MA packaging condition of individual persimmon fruit.
