Development of Modified Gas Composition for Atmosphere Packaging of Sliced Apple Chips

In this study, we report the development of mixed gas composition for packaging dried apple slices in a modified atmosphere to extend their shelf life and maintain their quality. We used the response surface methodology to optimize oxygen and carbon dioxide concentrations in the mixture for packaging in a modified atmosphere based on the changes in mass, hardness, browning index, polyphenols, and vitamin C content during apple chip storage. Studies have shown that the optimal concentration of oxygen should be 2.663% and carbon dioxide 3.785% when packaging dried apple slices in a modified atmosphere to obtain minimal changes in the measured quality attributes. These findings can be applied in food processing and storage, providing a useful guideline for improving the preservation and nutritional value of dried fruits.
