Abstract: An experiment was conducted to evaluate the effect of different postharvest treatments on maintaining the quality and prolonging the shelf life of sweet orange (Citrus Sinensis L. Osbeck.) from February to April 2021 at ambient room condition (15.49 ± 0.45⁰C and 69.68 ± 5.11%RH). The experiment was conducted under two-factor CRD with 9 treatments replicated thrice: bavistin, calcium chloride, control as the first factor and packaging materials, i.e. corrugated box, LDPE polythene, and open as the second factor. The data were taken at 8 days interval. The parameters recorded were Physiological weight loss, Juice Recovery Percentage, Total Soluble Solid (TSS), Titratable Acidity (TA), TSS/TA, pH, pathological disorder rating, and shelf life. Fruits stored in perforated plastic had minimum physiological weight loss (3.09%) whereas fruits kept open showed the highest weight loss (24.86%) at 56 days of storage. Minimum loss in weight was observed in fruits treated with bavistin (12.83%) and the maximum was observed in control (16.29%). The highest juice recovery percentage was observed in fruits treated with bavistin (30.34%) and fruits kept in perforated plastic (32.03%) and the minimum was observed in open fruits (25.82%). The highest TSS was recorded in fruits left untreated (14.26⁰ Brix) and fruit kept in open condition (15.17⁰ Brix) whereas the lowest was observed in fruits treated with bavistin (13.87⁰ Brix) and fruits stored in polythene (13.22⁰ Brix). The least decrease in TA was observed in bavistin-treated fruits (0.57) and fruits stored in perforated polythene (0.61) thereby, resulting highest TSS: TA ratio in untreated fruits (27.17) and fruit kept open (29.91). However, a non-significant effect was observed on pH by postharvest treatments. The pathological disorder was found minimum in the fruits treated with bavistin (2.00) which was at par with calcium chloride-treated fruits (2.33). The earlier pathological disorder was observed in fruits kept open and late with the minimum disorder was observed in fruits stored in perforated polythene. Postharvest life was found the maximum in fruits treated with bavistin and stored in perforated polythene (95 days) and the minimum was observed in fruits under control and left open (56 days).
