Q.4
Post Harvest Management- ICAR JRF/SRF 2024 (Q.103)
MCQ (Single Correct) +4 −1
Translucent flesh disorder is related to which fruit?
EXPLANATION Postharvest Disorders, Chilling Injury, Mechanical Injuries (Compression/Vibration) and Pathology of Fruits
  • Translucent Flesh Disorder in Mangosteen (Garcinia mangostana):
  • Also known as "gamboge" or water-soaking disorder, affecting the queen of fruits in Southeast Asia.
  • Characterized by white aril segments turning glassy, translucent, and water-soaked, developing a firm, rubbery texture and flat taste.
  • Triggered by heavy rainfall or excessive irrigation just before harvest, causing rapid xylem water influx into the fruit and hydrostatic rupture of aril cell walls.
  • Correct Option: Option 4 (Mangosteen).
