Abstract
Aims: Pomegranate (Punica granatum) is considered as challenging to consume due to its hard structure, hence used for fresh-cut production. Extending the shelf life of fresh-cut pomegranate arils would improve their marketability, transport efficiency, and reduce post-harvest losses. Study Design: Completely Randomized Design by using GRAPES (General R based Analysis Platform Empowered by Statistics). Place and Duration of Study: College of Agriculture, Kerala Agricultural University, February 2022-July 2024. Methodology: Pomegranate arils were extracted and treated with different pre-treatment solutions viz., 0.5% ascorbic acid, 0.5% citric acid, 1% calcium chloride and 1% calcium ascorbate for 4 minutes. The best pre-treatment solution was selected and arils were packaged in different packaging systems viz., shrink wrapping in 15µ polyolefin film, vacuum packaging in laminated pouches, MAP with N2 flushing in laminated pouches, aluminium tray wrapped with cling film and stored under two different storage conditions, after treating with 1% calcium ascorbate. Results: 1% calcium ascorbate was selected as the best pre-treatment solution and pre-treated arils kept in MAP with N2 flushing in laminated pouches stored under low temperature condition was found to be the best packaging and storage system. 1% calcium ascorbate treated arils in MAP with N2 flushing in laminated pouches stored under low temperature condition (10±5oC) had a shelf life of 6 days with superior physiological (PLW, percent leakage), chemical (acidity, vitamin C, phenol) and sensory characters (color, flavour, texture, appearance, taste and overall acceptability) as compared to control (2.00 days). Maximum vitamin C content of 23.02 mg 100g-1 and least phenol content of 214.16 mg 100g-1 were recorded on 6th day of storage. Conclusion: Pomegranate arils pre-treated with 1% calcium ascorbate for 4 minutes, kept in MAP with N2 flushing in laminated pouches stored under low temperature condition (10±5oC) can be considered as a protocol for shelf life extension of pomegranate arils.
