Abstract:
A study was conducted to determine the effect of packing material and storage conditions on the physiochemical changes that occurs during storage life of the palmyrah neera. The experiment was conducted in completely randomized factorial design with two factors at equal levels and replicated thrice. HDPE 50 micron pouch, PET bottle and glass bottle were the packing material and cold storage at 2 oC, cold storage at 4 oC, and refrigerated storage were the storage conditions used during the period of investigation. During the storage the physio-chemical properties viz., total soluble solids, pH and reducing sugars showed an increasing trend upto 4th week. Whereas, phenols, titrable acidity and alcohol content were increased upto 6th week of storage. Among the packing material maximum total soluble solids (10.80oBrix), reducing sugars (5.76%), total sugars (9.63%), minimum phenolic content (0.323 mg) and titrable acidity (1.116%) were recorded when palmyrah neera was packed in HDPE 50 micron pouch. Whereas, the maximum total soluble solids (10.83oBrix), reducing sugars (5.75%), total sugars (9.57%), minimum phenolic content (0.322 mg) and titrable acidity (1.266%) were recorded when palmyrah neera was stored in cold storage at 2 oC. However, interaction effect was found non significant. Superiority for sensory evaluation was reported for neera packed in LDPE 50 micron and stored in cold storage at 2 oC upto the end of the shelf life i.e., 6th week.
