You may think when it comes to keeping foods fresh, nothing beats the
refrigerator. Refrigeration keeps food fresh because bacterial growth
dramatically slows below 40°F. Refrigeration keeps plant foods like
lettuce or celery crisp because the cold temperature and low moisture
contracts cells and slows ripening. So what’s the best way to store food
properly?
However, some foods, like whole vegetables, fruits, and dry or baked
goods do not suffer from bacteria attack. Without the risk, there’s no
reason to take up the fridge space. In fact, for foods like avocado,
potato, and bread, the fridge conditions could cause damage or
degradation.
How to Store Food Without Refrigeration
Root Vegetables
- Carrots
- Potatoes
- Onions
- Turnips
Root vegetables have been common staples since long before the
refrigerator. In fact, many root vegetables that are popular today got
that way because they are convenient to stockpile for winter food
stores.
In the fridge, condensation can encourage mold growth and rot. The
veggies also take up valuable fridge space unnecessarily. The best way
to store root vegetables is in a cool, dry place, such as the pantry or
cupboard.
Foods with Ethylene Gas
- Banana
- Tomato
- Avocado
The fridge traps ethylene gas, a natural gas released by some fruits
and veggies including apples during ripening. You may recognize the
sweet, musky scent of ethylene next time you’re hovering around the
produce section of the supermarket.
The gas is a chemical trigger that tells many plants’ cells to
progress to the next stage of life. (Use this to your advantage by
placing under-ripe tomatoes or avocados in a paper bag with a few
apples.)
Starch and Sugar
- Bread
Low temperature speeds up the breakdown of the starch molecules in
bread and other baked goods, causing them to go stale faster. The fridge
also pulls moisture out of the bread, which can then condense inside
the bag, leading to wet, soggy bread.
- Chocolate
- Honey
- Olive Oil
Sugar-rich foods and syrups crystallize at low temperatures,
destroying flavor and texture. Many cooking oils thicken in the cold,
making them difficult to use.
Flavorful Foods
- Coffee
- Fresh Herbs
Foods with nuanced, delicate flavors absorb a “fridge-y” taste. To
store fresh herbs, place in fresh water in sunlight, just like cut
flowers. Coffee can be stored in an airtight container in a cool dark
place, or in an airtight container in the freezer.
Don’t Put Hot Leftovers In the Fridge Right Away
- Leftovers that are still hot
While you may think getting that soup straight into the fridge is the
best way to prevent bacteria growth, the truth is counter-intuitive.
Putting hot foods in the fridge can actually raise the overall
temperature of the fridge to above 40°F- putting all your food in the
bacterial “danger zone.”
The best way to cool hot food is to leave it on the counter, stirring
occasionally to release trapped heat, until it has reached room
temperature. As long as you pop it in the fridge within 4 hours of
cooking, it is perfectly safe.
Don’t forget to always store ready-to-eat foods above raw foods, such
as meats and shellfish. This prevents the raw juices dripping into your
food.
