| Summary, etc. | The present investigation entitled “postharvest management practices in papaya (carica papaya L) for improving shelf life” was conducted at department of processing technology, College of Agriculture, Vellayani to determine the stage of harvest maturity of papaya for local and distant market and to standardize postharvest practices for improved shelf life with minimum nutritional loss. The study was carried out in three different continuous experiments. For local market, papaya fruits harvested at ¼ yellow (144.37 DFFB – Days From Full Bloom) and ½ yellow (146.12 DFFB) stages revealed ¼ maturity as the best stage of harvest due to increased shelf life. For distant market, the fruits were harvested at one stripe yellow (142.00 DFFB) and fully mature green (139.38 DFFB) and fruits harvested at fully mature green stage had more shelf life and hence selected as best stage of harvest for distant market. Investigation on the efficacy of different sanitizing agents on surface decontamination revealed that papaya fruits harvested at ¼ yellow for local market and fully mature green fruits for distant market, washed and treated with hot water at 50% C for 20 minutes and warm sodium hypochloride at 150 ppm was effective in reducing bacterial and fungal population. The effect of waxing and ethylene absorbent was studied on papaya fruits harvested for local and distant markets, sanitized with the two best sanitising agents. For local market, fruits harvested at ¼ maturity and sanitised with hot water at 500 C for 20 minutes followed by cooling, waxing and packing with ethylene absorbent (KMnO4 – Potassium permanganate) 8.0/kg fruit as sachet in corrugated fibre board boxes recorded highest shelf life (11.00 days), lowest physiological loss in weight (1.84 per cent ), lowest loss in membrane integrity (58.18 percent leakage), lowest respiration rate (30.33 mg CO2 /kg/hr), highest total soluble solids (12.660 Brix), least microbial population and less mechanical damage. For distant market, fruits harvested at fully mature green stage sanitised with hot water at 500C for 20 minutes followed by cooling , waxing and packed in corrugated fibre board boxes with ethylene absorbent in sachet (KMnO4 8.0g/kg fruit) improved the shelf life (12.33 days) of fruits and showed lowest physiological loss in weight (2.08 per cent), lowest loss in membrane integrity (57.82 percent leakage), lowest respiration rate (35.00 mgCO2/kg/hr) higher total soluble solids (11.330 Brix), microbial population and less mechanical damage. Further studies are required for the refinement of the technology for reducing postharvest losses in papaya fruits for transport to distant market. |
