Recommendations for Maintaining Postharvest Quality

Maturity & Quality
Rambutan fruits are borne in clusters; each fruit has seeds surrounded by an aril (edible portion) which is covered by the pericarp and its hairs or soft spines or spinterns (1-1.5 cm long). Attainment of red color is the main harvest index. A minimum soluble solids content of 16% may also be used; cultivars vary in their maximum soluble solids content from 17 to 21%.

Temperature & Controlled Atmosphere
10-12°C (50-54°F) depending on cultivar (cultivars vary in their chilling sensitivity)
Storage potential = 12-14 days.
90-95%; maintenance of high RH is essential to minimizing water loss and preventing skin darkening (browning).
20-60ml CO2/kg·hr at 25°C (77°F); non-climacteric respiratory pattern.
0.1 to 0.7 µl/kg·hr at 25°C (77°F)
Rambutans are picked ripe and do not benefit from ethylene treatment or ethylene scrubbing during their postharvest handling.
An atmosphere of 3-5% O2 and 7-12% CO2 reduces respiration rate and retards red color loss and other symptoms of senescence. Postharvest-life potential in CA is 4 weeks (vs. 2 weeks in air).
