Abstract: Present investigation to study the influence of coating and packaging material on physico-chemical characters and shelf life of custard apple (Annona squamosa L.) cv. Balanagarframed in Factorial Completely Randomized Design (FCRD) with twelve treatments and three replications was during conducted during 2018. The experiment comprised of two factors namely coating (with and without wax coating) and 50 µ low density polyethylene bags (with 0.5%, 1%, 1.3% and 2% perforation, without perforation) and Punnet box. Matured fruits of uniform size, firm, free from pest, diseases and injuries were selected. For coating, fruits were dipped in aqueous solutions of bees wax for 5 minutes and dried for 30 minutes at room temperature. According to the treatment, fruits were packed in polyethylene bags and punnet and observation on changes in physic-chemical characters during storage on2nd, 4th, 6th, and 8th day and shelf life were recorded. Results revealed that there was significant impact of interaction among wax coating and packaging material on all parameters studied. When considered interaction, the treatment C2P5i.e. fruits coated with wax and packed in 50 µ low density polyethylene bags without perforation, had maximum TSS, total sugars, and minimum reduction of moisture per cent. This treatment registered the highest TSS (25.05 0Brix), total sugar (22.24%), least reduction in moisture (77.26%) and shelf life of 8 days. Overall results indicated the wax coating and packaging of custard apple fruits in 50 µ polyethylene bags (without perforations) improved the shelf life and at the same retained quality of fruits and the treatment combination C2P5i.e. fruits coated with wax and packed in 50 µ low density polyethylene bags without perforation was found to be promising.
