Effect of packaging materials on biochemical parameters of Ber (Ziziphus mauritianaLamk.) cultivars Thai Apple and Gola

An experiment was conducted in Post-harvest Laboratory of the Department of Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar to find the effect of packaging materials viz., corrugated fibre board boxes, sealed polyethylene bags,perforated polyethylene bags, polynet and control on biochemical parameters of ber cultivars Thai Apple and Gola stored at room temperature during February month of 2018. The data were recorded on TSS, acidity, TSS to acid ratio, ascorbic acid, total sugars,reducing sugars, non-reducing sugar and organoleptic quality. The results reveal that the Gola cultivar fruits of control treatment showed maximum total soluble solids, solids to acid ratio, reducing sugars, non-reducing sugar and total sugars with minimum acidity at the end of storage period. The fruits of Thai Apple cultivar packed in sealed polyethylene film bags had maximum ascorbic acid as compared to the fruits packed in other packaging materials and also to the fruits of Gola cultivar at the end of storage period. The fruits of Gola cultivar packed in corrugated fiber board boxes were rated best in organoleptic qualities as compared to the fruits packed in other packaging materials and also to the fruits of Thai Apple cultivar at the end of storage period. The results of the present study conclude that the corrugated fiber board boxes were found best for maintaining better oraganoleptic quality of Gola cultivar ber fruits up to eight days of storage under ambient room temperature conditions.
