Abstract

A study was conducted to optimize the ethylene concentration and exposure time for the ripening of fruits. Papaya fruit was selected and ripened by applying exogeneous ethylene in a farm level wooden ripening chamber and the ripened fruits were analysed for the quality parameters viz., physiological loss in weight, firmness, colour values, pH, TSS and organoleptic score. The fruits were ripened with three different ethylene concentrations and exposure times viz., 400, 500 and 600 ppm and 15, 20 and 25 hours respectively. The fruits treated with ethylene concentration of 600 ppm for an exposure time of 24 hours fared better with a physiological weight loss percent of 3.88, firmness value of 5.99 Newton, L, a and b value 59.10, 20.22 and 54.10 respectively, pH value of 5.7, TSS value of 14.8 organoleptic score of 8.3. Hence treatment combination of 600 ppm ethylene concentration and exposure time of 24 is optimum for ripening of papaya fruits.
