Notes:
: A model was developed to predict pO2 and pCO2 surrounding cut rutabaga sealed in rigid packages fitted with 2 different polymeric films. The O2 consumption and CO2 production rates were calculated using several respiration models fitted using nonlinear least squares or response surface regression analysis. These functions were used in conjunction with variables such as O2 and CO2film permeability, film surface area, package free volume, and cut rutabaga weight to predict pO2 and pCO2 changes. A first-order polynomial model with parameters calculated via response surface analysis gave the best predictions, particularly at partial pressures that were far removed from those used to determine equation constants.
