Eat Right Practice Exam

In order to prevent deterioration by slowing respiration, which item would be stored in modified-atmosphere packaging?

1. Bottled water

2. Apple slices

3. Ground turkey

4. Orange juice

The correct answer is: Apple slices

The correct answer is apple slices because modified-atmosphere packaging (MAP) is often utilized to extend the shelf life of perishable food items by altering the composition of the gas surrounding the food. In the case of apple slices, the packaging reduces the oxygen levels while increasing concentrations of carbon dioxide, which slows down respiration and oxidative processes. This results in less spoilage and helps maintain the quality and freshness of the fruit. Bottled water does not require modified-atmosphere packaging as it is non-perishable and not subject to respiration. Ground turkey, while it can benefit from reduced oxygen levels to slow spoilage, is often stored under different conditions due to its protein content and potential for bacterial growth. Orange juice, especially if it is pasteurized and sealed, also does not face the same respiration issues in the way that fresh produce does, making it less likely to require modified-atmosphere packaging in comparison to apple slices.
