Abstract

Freshly-harvested mature green mangoes (cvs. 'Alphonso' and 'Banganapalli') were individually shrink wrapped using two semi-permeable Cryovac films® (D-955 and LD-935) and a locally available LDPE film. The shrink wrapped and non-wrapped fruit were stored at 8 °C for 5 weeks and transferred to ambient conditions for subsequent ripening, to study the feasibility of alleviation of chilling injury (CI) and to determine shrink wrapping effect on fruit quality. Shrink wrapped mangoes of 'Banganapalli' and 'Alphonso' cultivars packed in D-955 (15 μm thickness) film could be stored for 5 weeks at 8 °C in fresh and unripe green condition. After storage, these cultivars respectively lost only 0.5 and 1.4 % mass in case of shrink wrapping as compared to 5.8 and 6.9 % loss in non-wrapped fruit. After removal from low temperature and unwrapping, shrink wrapped mangoes showed normal respiratory behaviour with production of CO2 and ethylene peaks (climacteric peaks) during ripening, whereas non-wrapped fruit did not show any respiratory peaks. Shrink wrapped mangoes ripened normally within a week at ambient temperature (24-32 °C and 60-70 % RH) with good surface yellow colour (reflected by hue and chroma values), edible softness, retention of nutritional quality and acceptable organoleptic quality. These quality parameters were better in fruit wrapped with D-955 film compared to LD-935 and LDPE films. Total carotenoids in terms of β-carotene content were significantly higher in shrink wrapped fruit when compared to non-wrapped fruit. Among different shrink films, total antioxidant capacity and DPPH radical scavenging abilities were higher in LD-935 wrapped fruit in case of 'Alphonso' cultivar whereas these were on par in LD-935 and D-955 film wrapped fruit in case of 'Banganapalli' cultivar.
