Etude préliminaire des effets de l'emballage sous atmosphère modifiée sur l'aptitude à l'entreposage des longanes.

Preliminary study on effects of modified atmosphere packaging on postharvest storage of longan fruit.

Auteurs : ZHANG D., QUANTICK P. C.

Résumé

Longan fruit were stored in modified atmosphere packaging consisting of 1% O2, 3% O2, 10% O2 and air (21% O2) for 7 days at room temperature and 35 days at 4 °C respectively to investigate the effects of modified atmosphere packaging; 0.03 mm thick polyethylene film was used. Results indicate that MAP consisting of 1% CO2 + 5% CO2, or 3% O2 + 5% CO2 was effective in delaying browning of the peel for 2 days or 1 day at room temperature and for 7 days or 5 days at 4 °C, respectively, in inhibiting the respiration of the fruit, in maintaining total soluble solids and ascorbic acid level of the fruit, and in partially inhibiting the activity of polyphenol oxidases. Taste panel results indicated that the MAP treatment consisting of 1% O2 + 5% CO2 produced slight off-flavours. This preliminary study indicates that establishing an atmosphere that is close to the desired atmosphere actively and quickly for the stored fruit is able to improve its storage behaviour.
