Description Ber is one of the commercial fruit crops grown in the tropical and sub-tropical region. Among the fruit trees, it requires the least inputs and care. It is considered to be “poor man’s apple” due to its high nutritional, medicinal value and low cost. Fruit is believed to purify blood and help in digestion. Ber fruits have an advantage that fruits are available in market during lean period and to ensure remunerative prices to growers. However, the storage life of ber is extremely short, hardly 2-4 days at ambient conditions and thus early perishability of fruit poses a problem. This study was therefore conducted to extend the quality and shelf life of ber fruits by low-cost effective packaging material. The ber fruits of cultivar Umran were procured from departmental orchard in HRC, Patharchatta, Pantnagar in district Udham Singh Nagar, Uttarakhand from areas located between 243.84 m amsl. Among the various packaging materials evaluated for packing of ber fruits, cardboard boxes were found suitable and economically viable containers involving least cost (` 3). Although physio-chemical properties were concerned during 10 days storage, the fruit length, diameter, weight, volume, acidity and ascorbic acid along with minimum physiological loss in weight, spoilage and specific gravity were found in cardboard boxes packed fruits. However, maximum specific gravity, physiological loss in weight, spoilage, TSS, total sugars, reducing sugars and non-reducing sugars of fruits were obtained in fruits packed in polythene net bags. Sensory scores for skin colour, flavour, taste, texture and overall acceptability were better in fruits packed in cardboard boxes. Therefore, storage of 100 kg ber fruits packed in cardboard boxes showed better quality as compared to polythene net bags under ambient storage. Economics calculated showed feasibility as on a total input of ` 1363.32 and ` 3000 is earned as gross returns with a net return of ` 1637. 68 with 2.20 B: C ratio.
On the basis of these findings, it may be concluded that ambient storage of ber fruits is possible for 8 days after packing of fruits in cardboard boxes of 250 g and retained the physical, chemical and sensory qualities. The benefit cost ratio of the technology was worked out to be 2.20.
