Conservação e fisiologia pós-colheita de folhas de Capuchinha (Tropaeolum majus L.)

ABSTRACT: Conservation and postharvest physiology of leaves Capuchin ( Tropaeolummajus L.) .This study aimed to evaluate the shelf-life of Capuchin sheets ( Tropaeolum majus L.)packed with plastic wrap and low density proteins at concentrations of 1, 3 and 5%. The experimentwas conducted at the Laboratorio de Quimica e Bioquimica and the Centro de Ciencias Agrarias(CCA) of the Universidade Federal da Paraiba (UFPB) Areia - PB. Capuchin leaves harvested inthe CCA were taken immediately to the Laboratorio de Quimica e Bioquimica, for pre-screening,disinfection in chlorinated water containing 100mg.L -1 of active chlorine, and dried at roomtemperature. After spraying, the leaves were treated as follows: protein solution at concentrationsof 1, 3 and 5%, low density plastic wrap and uncoated witness. The leaves were stored for fivedays in average temperature from 26 to 29°C and relative humidity from 59.5 to 71.5% and anotherpart was stored in cold with average temperature of 12 ± 0.5°C and relative humidity of 95 ± 3%.During the storage period the leaves were evaluated for weight loss, determination of ascorbicacid, soluble solids and titratable acidity. Storage for four days under refrigeration at an averagetemperature of 12 ± 0.5°C associated with PVC film coating showed better results in the conservationof shelf-life of Capuchin sheets.
