POSTHARVEST QUALITY OF CURED 'MAGALLANES' PUMMELO [CITRUS MAXIMA (BURM. EX RUMPH) MERR] FRUIT TREATED WITH 1-METHYLCYCLOPROPENE
The postharvest quality of cured Magallanes pummelo, a non-climacteric fruit, was evaluated every three weeks for 12 weeks after treatment (WAT) with various 1-methylcyclopropene (1-MCP) concentrations (0, 500, 1000, 1500, and 2000 nl L-1) at two treatment duration (4 and 8 h). Treatment at 500 nl L-1 reduced the percentage weight loss during holding in ambient conditions (28±0.72°C, 77±5% RH) starting at 6 WAT. Fruit also had a visual quality significantly better than other fruit at 9 and 12 WAT. While 1-MCP concentration did not affect granulation and decay, electrolyte leakage tended to be lower in treated fruit at 12 WAT. There was no consistent trend with TSS and TA as influenced by 1-MCP concentration. There was lower weight loss at 3, 6 and 9 WAT as well as lower granulation and higher TSS at 12 WAT when fruit were treated for 8 h. Cured Magallanes pummelo had better quality at ambient when treated with 500 nl L-1 1-MCP for 8 h.
