- Abstract
Pomegranate is an important table and processed fruit owing to its nutritional quality. Extending the fruit life of the plant is very much limited owing to its metabolic activities viz., respiration, transpiration and microbial infection. An experiment was conducted to investigate the effect of different packaging materials on physico-chemical properties of pomegranate fruits during storage. Fruits were harvested with stalk and washed with sodium hypochlorite, air dried and graded. Fruits were stored under modified atmospheric packaging conditions using different packaging materials viz., polyethylene bag, polypropylene bag, Xtend® bag and silver nano bag Hima Fresh®. Fruits without package served as controls. Fruits were stored at low temperature 7±2 °C and 90±5 % RH. MAP treated fruits had higher quality parameters across all packaging treatments. PLW and respiration rate increased while, moisture content, colour, texture and acidity decreased with prolonged storage, but the rate of decrease was highest in unpacked fruits. MAP maintained the quality of pomegranate fruits upto 100 days compared to unpackaged fruits (40 days). Shelf life of stored fruit at ambient condition was 4 to 5 days. Fruit decay was 12 % in polyethylene whereas it was 6 % in Xtend® bag at the end of 100 day of storage.
