Qualité des litchis après récolte : l'entreposage sous atmosphère contrôlée semble être la clé du succès.

Résumé

Defect-free, detached fruits (25 plus or minus 0.3 g) were placed into 1.765 L glass jars (n= 17 plus or minus 1 fruits/jar) where CA was applied utilizing a flow-through, humidified system at 5 °C. The CA treatments consisted of combinations of 3 or 4% O2 with 5, 10, or 15% CO2 atmospheres. Fruits stored in air were used as control. Fruit quality was assessed at regular intervals during 22 days of CA storage plus 1 day storage in air to simulate retail conditions. Weight loss, colour, hue angle and chroma values were studied. Significant reductions in soluble solids content were found in almost all treatments. Control fruits had the lowest titratable acidity. Total sugars were also significantly lower for all treatments. CA treatments showed negligible incidence of black spot and lesser incidence of stem-end decay. The sensory quality tests showed that 3/5 and 4/5 treatments were rated higher in flavour and texture than the other treatments; treatments involving 3/15 and 4/15 were rated lowest due to off-flavours.
