Impacts of the harvesting time and chemical treatments on "Java" rambutan quality (grown in Cho Lach, Ben Tre Province)
Main Article Content
Abstract
The study was conducted on surveys of impacts, including (i) the maturation (80 ÷ 100 days), (ii) post-harvest handling conditions [citric acid (0.25; 0.5; 0.75%) in combination with calcium chlorur (0.2; 0.3; 0.4%), ozonation (1; 1.5; 2 ppm) within 5 minutes] to the quality of post-harvest of “Java” rambutan (grown in Cho Lach, Ben Tre). Research results showed that the best harvesting time was 90 - 95 days after flowering, fruit in bright red, Brix degree of 17.5÷19. The quality criteria of fruit changed significantly. "Java" rambutan quality could be preserved up to 15 days when they were treated post-harvesting by citric acid together with calcium chlorur (0.5%, 0.4%), and stored in PP bag at 10°C.
