In what type of containers should leftovers be stored?

Leftovers should be stored in airtight containers to maintain their freshness and prevent contamination. Airtight containers are specifically designed to minimize exposure to air, which can lead to spoilage and the growth of bacteria. By sealing the food properly, these containers help retain moisture and flavor while protecting the food from external odors and pests.

Other storage options like plastic wrap may not create a complete seal, allowing some air to enter, which could lead to quicker spoilage. Open bowls do not provide any protection against air exposure, making them unsuitable for long-term storage of leftovers. Likewise, using paper bags is not advisable, as they do not keep food sealed, and food can dry out or become affected by external factors. Therefore, choosing airtight containers is the best practice for storing leftovers safely and effectively.
