Effect of Citrashine Coating on Post Harvest Quality of Grapefruit Cv. Star Ruby under Ambient Conditions

This study was conducted to observe the effect of citrashine coating on post harvest quality of grapefruit cv. Star Ruby under ambient conditions. For this, fully mature, uniform, healthy and disease free fruits of grapefruit cv Star Ruby were individually waxed with citrashine wax and kept at ambient temperature (2025°C) in well ventilated room. The fruits were analyzed for physiological loss in weight, organoleptic rating, spoilage, TSS and total acids after 7, 14 and 21 d of storage. Fruits coated with citrashine wax retained their general appearance and taste after storage. The physiological loss in weight (2.58%) and spoilage (0.0%) were minimum in citrashine treated fruits after 14 d of storage as compared to uncoated fruits where physiological loss in weight was recorded as 7.01 per cent and spoilage was 4.9 per cent. The wax treated fruits showed higher organoleptic rating up to 14 d of storage. Total soluble solids increased up to 14 d of storage interval. However, acidity decreased non-significantly with the increase in storage interval in both the treatments.
