tailieunhanh - Modelling the respiration rate of fresh-cut pear (Pyrus communis L.) packaged in modified atmosphere

Respiration rate is the important factor involved in creating a modified atmosphere inside a package that will extend the shelf life of fresh fruits and vegetables. Thus, modelling respiration rate of the selected produce is crucial to develop a modified atmosphere packaging (MAP) system. In this study, MAP has been combined with 1% Calcium chloride and 1% citric acid solution. Respiration rates of fresh-cut pear packaged in polypropylene pouches at 8 ˚C. A mathematical model describing the dynamics of O2 and CO2 concentrations inside the MAP package of fresh-cut pear was formulated. It was found that the Michaelis-Menten equation with uncompetitive inhibition kinetic fitted best with the experimental results. The results of the model agreed well with the experimental results with the values of the correlation coefficient, r2 >. The model could be used to develop a modified atmosphere packaging (MAP) for fresh-cut pear. | Modelling the respiration rate of fresh-cut pear (Pyrus communis L.) packaged in modified atmosphere
