Chilling Sensitivity
At storage temperatures less than 5°C (41°F), a slight
off-flavor can develop after about 1 week. The peel color
of longan stored at 0°C (32°F) turns dark brown, while
SO2-fumigated longan remain yellowish-brown. The
dark brown peel of longan that develops at very low
temperatures is regarded as chilling injury (La-Ongsri
et al. 1993).
