How should food be stored in a freezer to maintain quality?

Storing food in airtight containers is crucial for maintaining its quality in the freezer. Airtight containers prevent freezer burn, which occurs when air comes into contact with the surface of the food, causing dehydration and oxidation. This can lead to undesirable changes in flavor, texture, and overall quality. By sealing food properly within airtight containers, you effectively limit exposure to air, preserving the taste and texture while extending the food's shelf life.

While storing food in open containers might seem like it allows for air circulation, this exposure can negatively impact food quality by making it more susceptible to freezer burn. Original packaging may not provide adequate protection against air, moisture, or light, leading to similar quality issues. Placing food on the top shelf, while convenient for access, does not address the critical factor of protecting food from air exposure. Therefore, using airtight containers is the best practice to maintain the quality of frozen foods.
