ABSTRACT
An experiment was conducted to study the effect of pectin coating concentrations and packaging materials on shelf-life and quality of green pea pods stored under refrigerated condition (1+0.20C and 95% RH). Pectin coating of various concentrations (0.5%, 1.0%, 1.5% and 2.0%) were tried on fresh peapods in order to extend its marketing period. Coating was applied by immersion method. Coated and uncoated pea pods were kept in open crates, LDPE and HDPE bags of 100 gauge thickness. The quality of stored pea pods was evaluated on the basis of physiological loss in weight, colour, texture, decay %, chlorophyll content and organoleptic attributes at regular intervals throughout the storage study. It was observed that 1.0% pectin coated peas packed in HDPE packages recorded minimum changes in the quality parameters as compared to 0.5, 1.5 & 2.0% pectin coated and uncoated peas. It was possible to extend the shelf life of pea pods upto 56 days with acceptable quality attributes.
