 ABSTRACT

To assess the effect of various oil coatings on quality and shelf life of mandarin cv. Daisy a research trial was conducted at Department of Horticulture, Khalsa College, Amritsar during the year 2019-2020. Laboratory experiment was carried out under Complete Randomised Design (CRD) with eight treatments T1 (Rice bran oil), T2 (Olive oil), T3 (Coconut oil), T4 (Mustard oil), T5 (Cinnamon oil), T6 (Palm oil), T7 (Sesame oil) and T8 (Control) replicated thrice. After coating with various oils, the fruits were stored under ambient conditions (14.4°C; 80% RH). The fruits were then analyzed periodically for various quality attributes. Results of the study revealed that the coconut oil coated fruits had an immense effect on the reduction of physiological loss of weight (0.74%) and preserved firmness (7.33 lb force), TSS (12.45%), total sugars (7.83%) and ascorbic acid (10.83 mg/100ml juice) and non detection of microbes and their growth up to 21 days of storage.  Hence, coconut oil coated fruits proved quite effective in prolonging the shelf-life and maintaining the quality of Daisy mandarin fruits for 21 days compared to only 7 days in untreated fruits.
