Abstract:
Present study entitled, “Studies on coatings and packaging on shelf life and quality of custard apple cv. Balanagar” was conducted during the year 2022 by using different treatments combination of coatings and packaging which was replicated thrice in factorial randomized block design. Fresh and fully matured uniform sized custard apple fruits harvested at physiological stage of maturity were coated with different edible coating like bee wax (6%), sago concentration (5%, 10%), arrow root powder (5%, 10%), Aloe vera gel (50%, 75%), without coating (Control). Above treated fruits were packed in 50 µ low density polyethylene bags with 1% and 1.5% perforation along with control making the 24 treatment combinations. The results indicated that, significant impact of treatment combination of coating and packaging material on all parameters. The treatment combination of coating of bee wax (6%) and packed in 50 µ low density polyethylene bags with 1% perforation had shown significantly superior result than other treatments. In treatment combination of coating of bee wax (6%) and packed in 50 µ LDPE bags with 1% perforation it was observed that in physical parameters viz; maximum fruit weight (138.00 at 2^nd day, 137.04 at 4^th day, 134.28 at 6^th day and 130.99 g at 8^th day), peel weight (68.19 g, 67.47 g, 66.32 g and 64.39 g), pulp weight (60.05 g, 59.46 g, 58.31 g and 56.38 g) and fruit firmness (8.05, 7.00 and 6.18 kg/cm²), also in physico-chemical parameters viz; TSS (24.00, 25.33, 27.00 and 29.00 ^oBrix), total sugar (24.12, 26.00, 28.90 and 26.50%), reducing sugar (22.83, 23.93, 25.27, 21.56%), non-reducing sugar (3.04, 4.15, 6.20 and 9.50%) 2^th, 4^th, 6^th and 8^th day of storage moisture (77.47, 76.99 and 76.60%) at 4^th, 6^th and 8^th day of storage.
