Abstract

RIBEIRO, W.S. et al. Conservation and postharvest physiology of leaves Capuchin (Tropaeolum majus L.). Rev. bras. plantas med. [online]. 2011, vol.13, n.spe, pp. 598-605. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722011000500016.

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 experiment was conducted at the Laboratório de Química e Bioquímica and the Centro de Ciências Agrárias (CCA) of the Universidade Federal da Paraíba (UFPB) Areia - PB. Capuchin leaves harvested in the CCA were taken immediately to the Laboratório de Química e Bioquímica, for pre-screening, disinfection in chlorinated water containing 100mg.L-1 of active chlorine, and dried at room temperature. After spraying, the leaves were treated as follows: protein solution at concentrations of 1, 3 and 5%, low density plastic wrap and uncoated witness. The leaves were stored for five days in average temperature from 26 to 29ºC and relative humidity from 59.5 to 71.5% and another part was stored in cold with average temperature of 12 ± 0.5ºC and relative humidity of 95 ± 3%. During the storage period the leaves were evaluated for weight loss, determination of ascorbic acid, soluble solids and titratable acidity. Storage for four days under refrigeration at an average temperature of 12 ± 0.5ºC associated with PVC film coating showed better results in the conservation of shelf-life of Capuchin sheets.
