The experiment was laid out in Factorial Completely Randomize Design, which is replicated twice with two factors i.e. Factor A: edible coating, i.e. C₁-Control (without coated), C₂-Alginate (2%), C₃-Beeswax (2%), C₄-Aloe vera gel (75%), C₅-Tapioca starch (5%), C₆-Cinnamon oil (0.02%), C₇-Chitosan (0.5%), C₈-Acacia gum (5%), C₉-Pectin (2%). Factor B: packaging materials, i.e. P₁-Corrugated Fibre Boxe and P₂-Plastic crates. In this experiment, freshly harvested, mature, firm mango fruits were selected for each treatment combination and coated with nine different coating and packed in CFB box and Plastic crates as per the treatments. The treated fruits were stored at two different storage conditions viz. ambient temperature (AT) (26-30⁰C with 54-62% R.H) and cold storage (CS) (13⁰C with 90-95% R.H). Observations were taken at 4 days intervals up to the end of shelf life.

The coated fruits of mango packed and were stored at ambient temperature and cold storage it was found that there was increase in Physiological loss in weight, spoilage increase corresponding decrease in fruit firmness upon prolonged storage of mango fruit under both storage condition.

Fruit coated with beeswax 2% (T₂P₁) packed in CFB box at ambient temperature recorded significantly lowest PLW and higher firmness during storage. and also recorded minimum spoilage delay fruit ripening and longest shelf life during storage. Fruit coated with beeswax 2% (T₂P₁) packed in CFB box in cold storage recorded significantly lowest PLW and higher firmness during storag and also recorded no shriveling, minimum spoilage, delay fruit ripening and longest shelf life during storage. Higher sensory score for longer storage period was recorded in treatment T₇P₁ and T₃P₁.

The shelf life of control fruits (without coated) was found to be hardly 12 days at ambient temperature. The shelf life of fruit coated with chitosan 0.5% and beeswax 2% packed in CFB box was extended upto 16 days at ambient temperature during storage.

The shelf life of control fruits (without coated) was found to be hardly 20 days in cold storage. The shelf life of fruit coated with chitosan 0.5% and beeswax 2% packed in CFB box was extended upto 28 days at in cold storage during storage.
