Abstract
ABSTRACTQuantitative descriptive analysis was used to evaluate the influence of different temperature (1‐16°C) and gas conditions (air, 11% and 19% CO2) on visual quality changes in cut endive. Based on the coefficient of determination (R2), the residuals, the estimated intercept and the variance‐stabilizing characteristics of a logarithmic transformation, a first order model was selected to represent quality deterioration kinetics. The influence of temperature and gas composition on quality deterioration rate was modeled using a combined temperature (Arrhenius)‐gas composition (exponential relation)‐quality deterioration (first order) model. The model was validated under dynamic temperature conditions showing limitations of the Time‐Temperature‐Tolerance‐concept.
