Postharvest losses and influence of modified atmospheres, plastic film wrap, CO2 pretreatment and temperature on quality and storage life of 'Rong-rien' rambutan (Nephelium lappaceum Linn.) fruit
1993
Orasa Klaewkasetkorn
Postharvest losses caused by disease and insect were greater in the mid-season. Influence of modified atmospheres on storage life and quality of rambutans was investigated. Fruits were packed in corrugated cartons with and without polyethylene (PE) and polyvinyl chloride (PVC) liners; in sealed PE bags with and without ventilation holes; or treated with 15 and 50 % CO2 for 3, 6 and 12 hours prior to storage at 8, 10 and 12 deg C (90 % RH). Fruits stored at 18 and 10 deg C exhibited chilling injury (Cl) on day 6 and 8, respectively. Fruits stored in corrugated cartons with and without plastic film liners at 12 deg C had the longest storage life of 13.4-13.9 days but PVC liner gave a better quality. Fruits stored in sealed PE bags with 1 ventilation hole at 12 deg C in which contained 0.25-0.68 % CO2 and 16.13-19.52 % O2 had the longest storage life of 18 days and developed Cl more slowly, while the control had the storage life of 7.7 days and developed Cl earlier. Pretreatment with CO2 at 15 and 50 % for 3, 6 and 12 hours before storage did not affect biochemical changes and storage life but caused early wilting of spinters. Fruits were placed in foamtrays and wrapped with 'Reynolds' or 'Sun Wrap' PVC film and stored at 17 deg C (88 % RH). Fruits wrapped with 'Reynolds' PVC film had better quality and storage at 17 deg C was better than at 25 deg C.
