Caracterização pós-colheita de cagaitas submetidas a radiação UV-C

Abstract

Cagaita is a fruit of the Cerrado with high potential for fresh consumption, however, due to the low postharvest conservation, resulting from high respiratory rates and water losses, this potential is still limited. In this aspect, the aim of this study was to evaluate the cagaita postharvest characteristics submitted to different irradiation doses (UV-C). A completely randomized design was used, with four replications and factorial design 5x10 (UV-C radiation x days of analysis). The fruits were evaluated: mass loss, firmness, color, carotenoids, total phenolic compounds and antioxidant activity. The fruit analysis data were submitted to analysis of variance (P <0.05), regression and Tukey's test at 5% probability. The dose of 0,62 kJ m-2 promoted beneficial effects to the fruits, allowing for greater conservation of quality, maintaining the characteristics physical, physical-chemical, bioactive and in good conditions of commercialization for 12 days.
