Effect of Post-Harvest Degreening on Quality Parameters of Acid Lime Cv. Balaji

Abstract

Analyze the effect of post-harvest degreening on quality parameters of Acid lime cv. Balaji. The present research was conducted at Post harvest laboratory of College of Horticulture, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad, during the year 2018-2019. Experiment was designated with two factorial completely randomized design with two factors viz., (A) Ethylene concentrations, (B) Number of pulsings were taken for test and executed with the objective: Effect of post-harvest degreening on quality parameters of Acid lime cv. Balaji. The Acid lime cv. Balaji fruits were harvested and subjected to degreening treatments for one day. The treated Acid lime fruits were stored for sixteen days at ambient conditions. Acid lime fruits picked randomly from treated lot and evaluated for Physiological loss in weight %, Peel thickness mm, Fruit firmness Kg/cm2, Total soluble solids °Bx, Titratable acidity %, Ascorbic acid mg/100 g, Juice recovery % at four days interval by adopting the respective methods. Among all the quality parameters there were gradual increase in Total soluble solids (TSS), Juice recovery, Physiological loss in weight (PLW) and there were decreased trend in Titratable acidity, Peel thickness, Fruit firmness and Ascorbic acid content. Ethylene @ 15 ppm proved the better results for the above parameters. Among different number of pulsings, 1 pulsing in 24 hours @ 24 hrs interval and 2 pulsings in 24 hr @ 12 hrs interval was best.
