Resumen

Introduction: Currently, between 15 and 45 % of the harvested products are lost, there is a diversity of post-harvest technologies forthe preservation ofperishablefoods.The purpose of this research was to optimize and model the dehydration process of Musa paradisiaca through an artisanal solar dryer. For dehydration, 10 kg of green banana samples were obtained in the local market per week, longitudinal cuts of 0.45 ± 0.05cm were made to place in each of the trays of the solar dehydrator with an average weight of 1178.03 g per day. During15 days, the initial mass of the fresh product was taken daily with an analytical balance, it was weighed in three intervals, between 8:30 am-5:00 pm, in order to determine the variation of its masses. The result indicates that there is a significant relationship between the variables with a confidence level of 95.0 %. The explained variation of the model is 99.4683 % of the variability in moisture loss as a function of the independent variables. The reliability of the model to describe the behavior of the solar dryer and the final state of the product Is restricted to certain variables such as the humidity of the product, the temperature, the relative humidity of the indoor air, about which it is possible to be certain from the procedure, validation performed.
