Description The present investigation entitled "Studies on the effect of different post harvest chemicals on shelf life and quality of banana (Musa paradisica L.) cv. Grand Naine under ambient and refrigerated conditions" was carried out during 2011-2012 at Horticultural Research Station, Kovvur, West Godavari district of Andhra Pradesh.
Experiment was carried out to know the effect of different post harvest chemicals on physico - chemical parameters and shelf life of banana fruits at ambient and refrigerated storage conditions. The treatments are T1 (Sodium benzoate 500 ppm), T2 (Sodium benzoate 500 ppm kept in polythene cover), T3 (Ascorbic acid 1000 ppm), T4 (Ascorbic acid 1000 ppm kept in polythene cover), T5 (GA3 150 ppm), T6 (GA3 150 ppm kept in polythene cover), T7 (KMnO4 1%) and T8 (Control).
A set of two experiments were conducted in Completely Randomized Design with factorial concept and the treatments were replicated three times. Physico-chemical characters were recorded at 3 days interval at ambient condition and at 5 days interval at low temperature storage.
It was observed that the physiological loss in weight, colour index, spoilage rates, pulp to peel ratio increased while the fruit firmness, peel thickness decreased irrespective of the treatments with the advancement of storage period. Total soluble solids, reducing, non-reducing, total sugars and acidity increased initially and then decreased towards the end of the shelf life whereas ascorbic acid decreased towards the end of the storage period.
Under ambient condition, fruits treated with GA3 (150 ppm) kept in polythene cover (T6) recorded lower values for physiological loss in weight (6.58%), colour development (3.08), spoilage (16.39%), pulp to peel ratio (2.01) and Total soluble solids (15.43 0B). Similarly, the above treatment recorded higher values for firmness (3.19 kg/cm2), peel thickness (2.73 mm), acidity (0.34%), reducing sugars (8.56%), non-reducing sugars (4.46%), total sugars (13.02%) and ascorbic acid (11.25 mg/100gm) and thereby recorded more shelf life (18 days) than rest of the treatments. Organoleptic scoring for appearance, taste and over all acceptability was also higher when fruits were sprayed with GA3 (150 ppm) kept in polythene cover. Next to T6 (GA3 150 ppm kept in polythene cover), KMnO4 1% (T7) also recorded higher shelf life of 16.93 days.
At refrigerated storage, lower values for physiological loss in weight (5.19%), colour development (2.64), spoilage (15.93%), pulp to peel ratio (1.69) and Total soluble solids (13.98 0B) and higher values for firmness (3.85 kg/cm2), peel thickness (2.97mm), acidity (0.35%), reducing sugars (8.03%), non-reducing sugars (4.40%), total sugars (12.43%), ascorbic acid (11.42 mg/100gm) and organoleptic score were observed with GA3 150 ppm kept in polythene cover and thereby recorded higher shelf life of 40.42 days over other treatments. Next to T6 (GA3 150 ppm kept in polythene cover), SB 500 ppm kept in polythene cover (T2) recorded higher shelf life of 16 days over control.
Under both the conditions, fruits treated with GA3 (150 ppm) kept in polythene cover recorded higher shelf life and less spoilage of fruits as compared to other treatments.
