The Kinnow is the extensively cultivated variety of citrus fruit and a common name of mandarin (Citrus reticulate L.) in
Pakistan. Being a non-climacteric fruit, it keeps low storage life even in cold storage, because some physiochemical changes
may lose its quality. The current study was planned to check the efficacy of plant extracts in comparison with commercial
fungicide to enhance the storage life of Kinnow mandarin. Findings regarding the comparison of plant extracts and fungicide
(Thiabendazole) indicated that 60% Aloe vera extract showed similar results as synthetic fungicide (TBZ) and controlled fruit
decay up to 6.25%. The fruits of same treatment also showed better biochemical characteristics of fruit quality after storage of
90 days. The minimum changes in juice weight, TSS, titratable acidity and ascorbic acid were recorded in Aloe vera extract
treated fruits. Fruits coated with 60% Aloe vera extract also maintained higher levels of total phenolic (225.7 mg GAE 100g1
), antioxidant (76.3%) and enzyme activities of catalase (19.1 mg-1 protein), peroxidase (0.80 mg-1 protein), and superoxide
dismutase (130.4 mg-1 protein) during storage. It was evaluated that 60% Aloe vera extract proved valuable for long term
storage of Kinnow mandarin and to minimize the rotting of fruit during storage and
its performance was almost at par to commercial fungicide and maintained the fruit quality related parameters. Hence it can
be recommended to overcome the storage issues of Kinnow fruits.
