Pear being climacteric in nature has short storage life resulting in rapid loss of fruit quality after harvest. The present study aimed to determine the efficacy of composite coating of chitosan (CH) and salicylic acid (SA) on storage life and overall fruit quality of pear under cold and supermarket storage conditions. Application of combined CH + SA coatings delayed ripening index and reduced physico-chemical changes in stored pear fruit related to ripening in terms of soluble solid content, total sugars, titratable acidity as compared to pure CH or SA and control fruit. In addition, composite coatings had a positive impact on maintaining the fruit colour and sensory attributes over an extended period and efficiently enhanced the storage life up to 67 and 20 days of cold and supermarket storage conditions, respectively.
