Postharvest conservation of mangaba fruit treated with 1-methylcyclopropene and modified atmosphere

Abstract

The 1-methylcyclopropene (1-MCP) has been used in maintaining the quality and increase shelflife of many species of non-climacteric and climacteric fruits. The objective of this work was to evaluate the efficiency 1-MCP associated to modified atmosphere (MA) on postharvest quality maintenance of mangaba fruit. Fruits were harvested in maturation characterized by the presence of reddish spots, all over the yellow greenish pigmentation of the skin. The mangaba fruits were submitted to application of 1-MCP in the doses of 0, 100, 200 e 300 μL L -1 for 12 hours under room conditions (24 + 2 ° C and 83 + 2% RH) and evaluated for soluble solids (SS), titratable acidity (TA), SS/TA ratio, ascorbic acid, mass loss, and general appearance. The association of MA with 1-MCP did not provide additional benefits on quality. However, 1-MCP at 200 μL L -1 extended the postharvest life of mangaba, stored under and room conditions, from 5 to 7 days.
