Abstract: The present study entitiled "Effect of different coating material and packaging materials on quality and shelf life of Kinnow (Citrus nobilis X Citrus deliciosa) fruit." was conducted at department of horticulture, Post-Harvest laboratory, Naini agriculture college SHUATS, Prayagraj, U.P during the academic year 2022-24.Packaging and coating treatment includes T0 (Control/No coating & packaging), T₁ (Bee wax coated fruit packed in newspaper), T₂ (Bee wax coated fruit packed in brown paper), T₃ (Bee wax coated fruit packed in HDPE), T₄ (Acacia gum coated fruit packed in newspaper), T₅ (Acacia gum coated fruit packed in brown paper), T₆ (Acacia gum coated fruit packed in HDPE), T₇ (Guar gum coated fruit packed in newspaper), T₈ (Guar gum coated fruit packed in brown paper) T₉ (Guar gum coated fruit packed in HDPE). The physical, biochemical and organoleptic assessment of each treatment result was conducted up to 21 days and at every 7 days interval, all observation were recorded. The PLW (%) and Volume loss (%) were recorded lowest in the fruits packed in T₅ during storage which were (3.45%) and (0.74%) respectively. Total soluble solids and total sugar contents had increasing trend during storage period and found highest (11.89) and (10.69) in T₅ treatment respectively at 21 days while ascorbic acid and titrable acidity had decreasing trend and mean value was found highest (16.31) and (0.81) in T₅ treatment respectively during storage. On the basic of organoleptic evaluation nine-point hedonic rating scale, it was concluded that Kinnow fruits packed under Acacia Gum Coating+ Brown Paper Wrapping scored highest overall acceptability at 21 days of storage, and it can be recommended to farmers for prolonging the storability of the fruits at ambient conditions.
