Abstract:
Polyamines are the natural compound that plays a pivotal role in postharvest life of fruits and vegetables. The study was conducted with an objective to investigate the effect of post-harvest application of polyamines in different concentration on biochemical quality parameters and shelf life of papaya fruits during ambient storage (33-36 oC). Papaya fruits are treated with different concentration of polyamines i.e., T2-0.50mM Spermine, T3- 1.0mM Spermine, T4- 1.5mM Spermine, T5- 0.50 mM Spermidine, T6- 1 mM Spermidine, T7- 1.5mM Spermidine, T8- 2 mM Putrescine, T9- 3 mM Putrescine, T10- 4 mM Putrescine and T1-Control. Among the treatments, papaya fruits treated with 4 mM of Putrescine (T10) recorded significantly minimum total soluble solids (10.90 oB), ß-carotene (0.76mg/100g) and maximum titratable acidity (0.34%), total phenols (180.92mg GAE/g) and shelf life (9 days) and sensory scores (overall acceptability- 8.46). Hence, it is confirmed from the study that the Putrescine at 4 mM (T10) was found to be effective in delaying the biochemical and ripening of papaya fruits and maintaining the organoleptic qualities for long time.
