The study was focused to determine the effect of packing material and storageconditions on the physio-chemical changes that occurs during the storage life of the palmyrah tenderfruit endosperm (nungu). The experiment was conducted in completely randomized factorial designwith two factors at unequal levels and replicated thrice. LDPE 50 micron pouch, HDPE 50 micronpouch and aluminium foil pouch were the packing material and ice box, cold storage at 2oC, coldstorage at 4oC and refrigerated storage were the storage conditions used during the period ofinvestigation. During the storage the physico-chemical properties like total soluble solids, pH andreducing sugars followed an increasing trend upto 6th day. Whereas, this highest browning andtitrable acidity content were recorded upto 8th day of storage. Significant difference for physicochemicalproperties viz., maximum total soluble solids (7.16oBrix), reducing sugars (5.41%),minimum titrable acidity (0.418%) and browning (0.026%) were recorded when palmyrah tender fruitendosperm was packed in LDPE 50 micron pouch. Similarly, the maximum total soluble solids(8.94oBrix), reducing sugars (5.39%), minimum titrable acidity (0.429%) and browning (0.028%)were recorded when palmyrah tender fruit endosperm was stored in cold storage at 2oC. Superiorityfor sensory evaluation was reported for nungu packed in LDPE 50 micron and stored in cold storageat 2oC upto the end of the shelf life i.e., 8th day.
