Abstract
Annona (Annona spp.) is a tropical underutilized fruit with growing demand in both local and export markets for their distinct tastes and promising health benefits. However, vulnerability to postharvest damages with the short postharvest life of this commodity has significantly affected their market potential. The present study attempts to extend postharvest life while maintaining postharvest qualities in Atemoya (Annona atemoya), Bullock’s heart (Annona reticulata), Soursop (Annona muricata) and Sugar apple (Annona squamosa).
The experiment was conducted according to the Complete Randomized Design (CRD) using four treatments. Fruits were treated with 0, 0.3, 0.6 and 0.9 μL L-1 1-Methylcyclopropene (1-MCP) for 15 hours and stored under ambient temperature (27±1 0C). Fresh weight loss, firmness, total soluble solids, titratable acidity and peel colour changes were evaluated in two-day intervals.
Fruit weight loss, firmness loss and concentration of titratable acidity showed strong positive correlation with time. Among the treatments, Annona fruits treated with 0.6 μL L
-1 1-MCP reduced the chlorophyll degradation, fresh weight loss, total soluble solids and firmness loss. Peel colour indices L* and b* could be used to detect ripening of Annona. This study provides different 1-MCP concentrations that are effective to increase the postharvest life and postharvest qualities of four selected Annona species in Sri Lanka.
