Description
A new method for estimating respiration rate of fruits and vegetables in a modified atmosphere package (MAP) was developed, using the tomato fruit as an example. On the basis of the measured data of the gas partial pressures in the package, the oxygen consumption rate and carbon dioxide evolution rate were determined by computer using the non-linear least-squares method. The free volume of the pouch with packed tomato fruit was also determined simultaneously in the computation. The estimated values of respiration rates for tomato fruit were 9-13ml/kg · hr at 20°C. These values agreed well with those reported Previously by several investigators. The phenomena that the package wrapped with fresh fruits and vegetables shrank during storage can be explained theoretically by the result dependent on computation that the free volume in the package was decreased with the passage of time. A new calculation method is useful for the estimation of respiration rate in modeling MAP under unsteady conditions.
