Abstract
In the present study modified atmospheric (MA) packages, having package size of 19 × 19 cm2 for a fill weight of 500 ± 100 g were developed for the experimental purpose. The storage study of MA packages was performed at 10 ± 1, 18 ± 1 and 27 ± 1 °C temperatures, considering low-density polyethylene (LDPE) packaging film with 0.1, 0.05, 0.025 and 0.0125% perforations. The performance of film packages was evaluated for their ability to establish equilibrium condition at target levels and to extend the shelf life of the packaged fruit and vegetable. It was observed that ratio of the respiration rate of O2 and CO2 prominently depends upon the perforation rate and variations in storage temperature. The LDPE packages having 0.0125% perforations have maintained the respiration rate the most in both the cases of O2 and CO2 up to 90 h at 0.89 ml kg−1 at a refrigerated temperature of 10 °C. The results showed that LDPE film with 0.0125% perforation was found best suitable for packaging both tomato and mango.
