| Abstract:
The use of MAP to extend shelf life of fruits and vegetables is stressed in the present work, increasing in at least a 200% the shelf life of the products. For the tomato assay using cellophane film at 25°C and a RH 85–90% a shelf life of 35 days was obtained; for spinach packed of LPDE at 0° and 2°C, a RH 85–90%, up to 26 days were obtained. The parameters chosen for evaluation were: loss weight, Vit. C, color, °Brix, texture, acidity and general appearance. The methodology employed was devised in the lab involving the quality of the starting material, selection of critical concentration of CO2 and O2 and films as well as the conformation for the package and shelf life tests. The data were evaluated using ANOVA, comparative range for parametric variables and Friedman for non-parametric. The extrapolation of these data allow its application to several tropical products. | |
