dc.description.abstractThe present study entitled “Effect of edible surface coatings on storage behavior of mango fruit cv. Dusehri” was carried out in the Department of Fruit Science, PAU, Ludhiana during the year 2018. The mature and uniform fruits were harvested in the month of July and thoroughly washed, sanitized, dried up in shade and afterwards coated with Aloe vera gel 50%, Aloe vera gel 100%, beeswax 1.5%, beeswax 3.0%, chitosan 0.5%, chitosan 1.0% and control treatment (uncoated fruits). The fruits were placed in CFB (5% ventilation) boxes and subsequently stored at cold room (10 ºC±1 and 90-95% RH). The fruits were analyzed after 0, 7, 14, 21 and 28 days of storage. Physiological loss weight in mango fruits decreased with storage however, fruits treated with beeswax 3.0% recorded significantly lower physiological loss in weight as compared to other treatments. Likewise, titratable acidity, fruit firmness, and vitamin C showed decreasing tendency with increase in storage period. Total soluble solids (TSS), colour changes, - carotenoids and sugars were increased progressively up to 28th day of cold storage. Fruit sensory quality rating was increased up to 21 days except in control fruits where the sensory quality increased up to 14 days followed by decline up to 28th day of storage. The enzymatic (Cellulase, amylase and polygalacturonase) activities were increased up to 14th day followed by decline up to 28th day of storage. During cold storage, beeswax 3.0% was found to be most effective in extending the storage life mango fruit cv. Dusehri with acceptable quality of fruits during the entire storage period.en_US
