Abstract:
An investigation was carried out to know the effectiveness of different post-harvest treatments on storage behaviour, physiological, physico-chemical changes and organoleptic parameters of jamun fruits at ambient storage. The treatments involved post-harvest application of calcium chloride (1.0 and 2.0%), GA₃ (50 and 100ppm) and sachets containing iron powder (1 and 1.5g/kg fruits) and potassium permanganate (5 and 10g/kg of fruits).Minimum respiration rate (32.32 ml CO₂/kg/h), rotting percentage (17.86%), highest retention of titratable acidity (1.39%), Phenols (200.70 mg/100g) and antioxidant activity (87.13%) was recorded in the fruits with sachets containing iron powder (1g/kg of fruits) during the storage period up to 6 days after storage respectively. The fruits with sachets containing iron powder (1g/kg of fruits) extend shelf life up to 6 days at ambient storage and it was superior to all other treatments in maintaining better physiological behaviour, physico-chemical characters and organoleptic qualities under ambient storage conditions.
