Yes, cut fruits should be stored in airtight containers in the refrigerator to prevent oxidation, maintain moisture, and inhibit bacterial growth. This helps them stay fresh and safe to eat for a longer period.
When fruit is cut, its cells are damaged, leading to enzymatic browning (oxidation). This process causes the fruit to discolor and lose some of its nutrients and flavor. Airtight containers minimize exposure to oxygen, slowing down oxidation. Furthermore, cut fruits release moisture, which can lead to sogginess and promote bacterial growth. An airtight container helps to retain the fruit's natural moisture while preventing it from becoming overly wet. Finally, airtight containers prevent the fruit from absorbing odors from other foods in the refrigerator, preserving its taste. Storing cut fruit properly extends its shelf life and ensures it remains appealing and safe to consume.
To further extend the freshness of cut fruits, consider adding a squeeze of lemon or lime juice before storing them in an airtight container. The citric acid acts as a natural antioxidant, further slowing down the browning process.
