ABSTRACT
An investigation held on the effect of different coating materials on quality and shelf-life of custard apple (Annona squamosa L.) cv. Local was carried out during November, 2019 under ambient room temperature at Post Graduate Laboratory, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand. Freshly harvested uniform sized custard apple fruits were selected, washed, cleaned and treated with different levels of Aloe vera gel (10 % and 20 %), Bee wax (1 % and 2 %), Gum arabic (5 % and 10 %), Chitosan (1 % and 2 %) and Calcium nitrate (1 % and 2 %). All the treated fruits were stored in well ventilated CFB boxes in laboratory. The experiment was framed in Completely Randomized Design and repeated thrice with eleven treatments. The result obtained from the present investigation that fruit coated with chitosan 2 % recorded significantly lowest physiological loss in weight and fruit spoilage with highest firmness and marketable fruits during storage period. Chitosan 1 % was at par with chitosan 2 % for all the physical parameters during storage period. The highest shelf-life (8.1 days) was also found with chitosan 2 % coated fruits, which at par with chitosan 1 % (7.8 days) under ambient storage condition.
