Effect of post harvest treatments, packaging materials on extension of shelf life of custard apple (Annona squamosa L.) fruits.    The present investigation was undertaken to study the effect of post harvest treatments, packaging materials o­n extension of shelf life of custard apple (Annona squamosa L.) fruits.For this purpose, the custard apple fruits were harvested at proper stage of maturity and given post harvest treatments viz., waxing (6%), NAA (30 ppm), KmnO4 packing either alone or in combination.The custard apple fruits were then packed in polyethylene bags (2% vents and 100 gauge thickness) and some fruits were wrapped individually by special polyfilm (75 gauge thickness).These fruits were stored at room temperature (6.12 to 35.18 °C and 25.50 to 89.00% RH) and in zero energy cool chamber (7.10 to 17.00 °C and 80.00 to 93.45% RH).

It was found that the shelf life of custard apple fruits could be extended up to 7 days when treated with waxol or waxol + KmnO4 or waxol + NAA (30 ppm) and packed in individual wrapping polyfilm at room temperature as against 4 days of control o­nes.The shelf life of custard apple fruits was extended up to 11 days under the same treatments when stored in cool chamber.The fruits treated with waxol + NAA (30 ppm) and packed in individual wrapping ployfilm treatment registered the best with the highest orgonoleptic score.Moreover, cool chamber has the added advantage of easy construction, maintenance and low cost.
