Shelf-life of BRS Pérola do Cerrado passion fruit under diferente forms of conservation. In: Agrotrópica v. 33 n. 3 p. 187-196, 2021.

Abstract

Brazil is the main producer of passion fruit in the world, and this crop has, steadily, grown in importance for brazilian agribusiness. The objective of this study was to evaluate the post-harvest conservation of BRS Pérola do Cerrado (Passiflora setacea) passion fruit in 10 μm PVC packages, 30 μm HDPE packages, coated with 12% carnauba wax and without any packaging (control) stored under ambient conditions at 25 ºC and 70% of relative humidity and in refrigerated conditions at 10 °C and 90% relative humidity for 14 days. Parameters such as pH, titratable acidity, soluble solids, fresh weight loss percentage, luminosity, increment in browning, chromaticity, hue angle, texture (via texturometer) and fruit microbiology were analyzed at 0, 7 and 14 days of storage. The concentration of O2 and CO2 inside the packages was also analyzed. Refrigerated storage at a temperature of 10 ºC and 90% relative humidity and the use of 10 μm PVC packaging were beneficial for BRS Pérola do Cerrado passion fruit conservation up to 14 days after harvesting. Ambient condition storage was not suitable for long-term fruit conservation.
