In Your Refrigerator
Temperature fluctuates the most on a refrigerator door. Store eggs and milk on a shelf rather than a door to prolong freshness. Don’t overfill the shelves of your refrigerator — the air needs to circulate freely around the contents to keep them cool.
Keep vegetables and fruits separated in produce drawers and don’t wash produce before refrigerating it. Use bubble wrap along the bottom of the fruit drawer to prevent bruising.
When storing things like sauces and soups in the freezer, only fill the container three-quarters to allow room for expansion when frozen. Store these in small quantities so the food freezes more quickly, which gives it a fresher taste.
