Modelling colour of tomatoes: advantage of multiple nonlinear regression.

Author(s) : TIJSKENS L. M. M.

Summary

The behaviour of tomato colour was studied during storage at both optimal and suboptimal temperature conditions. A mathematical model is developed describing the behaviour of tomato colour at different temperatures during storage and at different harvest maturity stages. The mathematical description used in the model is a logistic (sigmoid) function with a correction for the actual biological age of the tomato. The model is useful not only as a descriptive or predictive tool, but also as the basis for statistical analysis of the measured data with integral non-linear regression. Accuracy in prediction of colour development is highly dependent on the stage of maturity.
