ARMAZENAMENTO REFRIGERADO DE MELÃO GALIA 'SOLARKING' SOB ATMOSFERA MODIFICADA

Abstract

The postharvest shelflife of Galia Solarking melons was evaluated at the Postharvest Study Center, Escola Superior de Agricultura de Mossoró, RN, Brazil. The treatments consisted of submitting the hybrid to the experimental temperature at 5, 7, 9 and 11ºC under 90 ± 5% relative humidity, with or without modified atmosphere (MAP), with evaluations in nine days intervals (7 days under cold storage plus 2 days at room temperature), with the determination of weight loss, external and internal appearances, flesh firmness and total soluble solids content. A 4 x 2 x 5 (temperature x presence or absence of plastic film x time of storage) factorial scheme in a completely randomized design with three repetitions and one fruit per plot was utilized. Weight loss was smaller for the fruits under modified atmosphere. Larger values of flesh firmness were verified for fruits stored under modified atmosphere stored at 5ºC. Based on the external appearance, the postharvest shelflife of Solarking melons were 27 days for 5, 7 and 9ºC storage temperatures and 18 days for 11ºC.
