The present investigation entitled Effect of packing material and storage conditions on natural and value added products of palmyrah (Borassus flabellifer L.)” was carried out with an objective to investigate the influence of different packing material and storage conditions on shelf life and keeping quality of natural and value added products of palmyrah during March 2018 to January 2020 at Postharvest Technology Research Station,          Dr.Y.S.R Horticultural University, Venkataramannagudem, West Godavari District.
The experiment was conducted in completely randomized factorial design with two factors at unequal levels and replicated thrice. LDPE50 micron pouch, HDPE 50 micron pouch, aluminium foil pouches, PET bottle and glass bottle were the packing material and  ice box, cold storage at 2oC, cold storage at 4oC, refrigerated storage and ambient conditions were the storage conditions used during the period of investigation.
Results revealed that, in all the experiments physico-chemical parameters like total soluble solids (oBrix), reducing sugars (%), phenolic content (mg), titrable acidity (%), alcohol content (%), physiological loss in weight (PLW %), spoilage (%), browning (%) and moisture content (%) followed an increasing trend, whereas parameters such as pH, total sugars (%), non-reducing sugars (%), shelf life (days), fiber (%), protein (%) and starch (%) followed a decreasing trend from the initial day to the end of storage. The decreasing trend was observed for organoleptic parameters like taste, flavour, texture and overall acceptability.
The 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. Similarly, 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%) was recorded when palmyrah neera was stored in cold storage at 2oC.
The maximum total soluble solids (7.16oBrix), reducing sugars (5.41%), total sugars (8.59%), shelf life (6.10 days), minimum titrable acidity (0.418%), physiological loss in weight (3.46%), spoilage (34.7%) and browning (0.026%) were recorded when palmyrah tender fruit endosperm (nungu) was packed in LDPE 50 micron pouch. Similarly, the maximum total soluble solids             (8.94oBrix), reducing sugars (5.39%), shelf life (7.50 days), minimum titrable acidity (0.429%), physiological loss in weight (3.52%), spoilage (35.15%) and browning (0.028%) were recorded when palmyrah tender fruit endosperm (nungu) was stored in cold storage at 2oC.
The maximum total soluble solids (9.07oBrix), reducing sugars (5.72%), total sugars (8.30%) and minimum phenolic content (0.195 mg) of palmyrah jaggery was recorded when packed in LDPE 50 micron pouch. Similarly, the maximum total soluble solids (9.00oBrix), reducing sugars (5.75%), total sugars (8.08%) and minimum phenolic content (0.192 mg) of palmyrah jaggery was recorded when stored in cold storage at 2oC.
The maximum total soluble solids (6.60oBrix), reducing sugars (10.20%), total sugars (15.23%), protein content (2.53%), fibre content (10.96%), minimum titrable acidity (1.42%) and phenolic content (15.73 mg) were recorded for palmyrah tuber flour packed in LDPE 50 micron pouch. Similarly, the maximum total soluble solids (6.63oBrix), reducing sugars (10.12%), total sugars (15.05%), protein content (2.49%), fibre content (10.45%), minimum titrable acidity (1.40%) and phenolic content (15.61 mg) of palmyrah tuber flour was recorded in cold storage at 2oC.
The organoleptic score for the palmyrah neera, palmyrah tender fruit endosperm (nungu) and jaggery followed a decreasing trend during the period of storage, and the best score for taste, flavour, texture and overall acceptability was recorded for products packed in LDPE 50 micron pouch and stored in cold storage at 2oC.
The highest benefit cost ratios were obtained in the treatment combination of HDPE 50 micron and cold storage at 2oC in neera (2.01), LDPE 50 micron pouch and cold storage at 2oC in nungu (1.93), jaggery (1.32) and tuber flour (1.20).

The present investigation revealed that, the superiority for             physico-chemical, sensory parameters and benefit cost ratios of neera were recorded when packed in HDPE 50 micron pouch and stored in cold storage        at 2oC whereas, for palmyrah tender fruit endosperm (nungu), jaggery and tuber flour were recorded when packed in LDPE 50 micron pouch and stored in cold storage at 2oC.
