ABSTRACT The present studies entitled, “Evaluation of drying modes and packaging material for storage of wild pomegranate (Punica granatumL.) arils” were conducted during 2011-2012 in the Department of Food Science and Technology, Dr YS Parmar University of Horticulture and Forestry, Nauni-173230, Solan (HP). Wild pomegranate (Punica granatum L.) is the only wild fruit which has got commercial importance because of its high acidic nature. It is used as an acidulant in curries, chutneys and many other culinary preparations. It is also considered as a good source of an antioxidant because of the presence of various compounds like phenols, anthocyanins, ascorbic acid etc. in it. The freshly extracted arils of wild pomegranate fruit were pre-treated (steam blanching for 30 sec followed by sulphuring @ 0.3 per cent for 60 min) to check the browning as suggested by Thakur et al., 2010. Three drying modes like mechanical cabinet drier, solar tunnel drier and open sun were compared to dry the pretreated arils on the basis of various physico-chemical and sensory quality characteristics. The arils from the best drying mode (mechanical cabinet drier; 60 + 2oC) possessing maximum desirable sensory and physico-chemical characteristics were packed and stored in nine different packaging treatments viz., aluminium laminated pouches (ALP) polyethylene pouches (PEP), thermofoam trays (TT), ALP+5% sugar, PEP+ 5% sugar, TT+5%+ sugar, ALP+5% Salt, PEP+5% salt and TT+ 5%+ Salt for 6 months under ambient storage conditions. Although the slight changes in various physicochemical characteristics like moisture, TS, titratable acidity, pH, reducing sugars, total sugars, ascorbic acid, anthocyanins, phenols, NEB, furfural, HMF, and sensory quality characteristics of dried arils occurred during storage but the arils packed in aluminium laminated pouch containing either salt or sugar retained most of these characteristics better than other packaging treatments. So aluminium laminated pouch can be used as a packaging material for the packaging of dried arils (anardana) on commercial scale. Putting of salt or sugar sachet along with the arils inside the pouch will be an additional advantage to retain the quality of anardana . |
