Incorporating biological variation in postharvest modelling. Using colour change of tomato fruit (Lycopersicon esculentum Mill.) as a case study, a stochastic kinetic approach is developed to interpret postharvest batch behaviour combining kinetic models with the concept of biological age governed by stochastic processes.Data from a wide range of cultivars stored at 18 °C will be used to illustrate the concept of biological age and to discriminate between batch and cultivar depending parameters.

Tomatoes from three cultivars (Quest, Style and Tradiro) were stored at 3 storage temperatures (12, 15 and 18 °C).Data from these experiments were used to develop the stochastic kinetic model appr9oach predicting the propagation of biological variation during poastharvest describing colour change as a function of time and temperature.

An independent validation experiment o­n Tradiro tomato stored at 18 °C showed that the developed approach is able to accurately predict propagation of biological variation during postharvest (R2adj=0.96) based o­n just the initial colour distribution measured at harvest.The developed approach will also be extended to describe batch behaviour under varying temperature conditions enabling the application to more realistic postharvest conditions.
