Abstract:
This study was designed to optimize the suitable type and concentration of edible coating formulations viz. polysaccharide based, protein based and lipid based coatings coated as single layer, composite and bilayer on the mango cv. Alphonso for the purpose of preservation and shelf life extension. The experiment were divide into three phases as single layer coating composite coating and bilayer coating. In bilayer experiment the fruits were stored under two different storage conditions of cold and ambient. The results for physiological weight loss was measured after an interval of 3 days throughout the storage period. The best and optimized results obtained from each phase was used for the latter. The results showed that from the phase I treatment E2, E3, E5, E7, E9, E11 were found to have lower values for PLW as compared to the treatments of higher concentration from the respective groups except group of chitosan where higher concentration of chitosan showed good results. From the phase II i.e. composite coating formulations the best optimized results were found for the treatment T5, T11 and T14 which were selected for the phase III i.e bilayer coating experiment.
