Counter, fridge or freezer: the numbers
How freezing changes liquid egg substitute
Raw eggs can't go into the freezer in their shells, because the contents expand and split the shell. Whole eggs beaten together, or whites and yolks frozen separately, hold up well; stir a pinch of sugar or salt into yolks so they don't thicken into a gel. Cooked egg whites go rubbery when frozen.
How long liquid egg substitute keeps with each storage method

| Freezer (opened) | Not recommended | 0°F / -18°C | Wrapped or freezer bag | hurts texture or safety |

Getting to know liquid egg substitute
Liquid egg substitute sits in the dairy & eggs section of our food guide. The USDA FoodKeeper database files it under the name “Egg substitutes (liquid)”. Going by USDA FoodKeeper, it lasts 3 days in the fridge. Freezing is not advised. As with any perishable food, it shouldn't spend more than 2 hours at room temperature. Best storage spot: choose a middle shelf over the door, which warms up each time someone opens it.
Thanks to the shell and the thin membranes just inside it, eggs last for weeks in the fridge. Eggs sold in the US are washed before they reach stores, a step that strips off the shell's natural protective coating, so they have to stay refrigerated. Once an egg is cracked, separated or cooked, its storage time shrinks sharply.
What makes liquid egg substitute spoil
Salmonella is the key safety concern with eggs, and it can lurk inside an egg with a perfectly ordinary appearance. As they age, eggs gradually give up water and carbon dioxide through the porous shell, so the white turns runny and the yolk sits flatter. An egg that has truly gone bad gives off a sulfur smell as bacteria break down its proteins.
Mistakes people make storing liquid egg substitute
- Storing the carton in the door, where temperatures go up and down.
- Washing eggs before putting them away.
- Letting cold eggs sit out longer than two hours: condensation on a cold egg can help bacteria get through the shell.
- Freezing whole eggs in their shells, which makes the shells split.
Choosing good liquid egg substitute at the store
- Open the carton before you buy and make sure none of the eggs are cracked or dirty.
- Only buy eggs that are sold from a refrigerated case.
- Leave them in the carton, which shields them and keeps the pack date in view.
Liquid egg substitute: ways to finish it in time
- Make a batch of hard-boiled eggs; they keep for a week in the fridge.
- Beat any extras together and freeze them for baking.
- Use them up in quiches, frittatas, custards and baked goods.
Making sense of expiration dates
The dates printed on liquid egg substitute packaging mostly describe quality rather than safety. Under US rules, infant formula's use-by date is the only one federal rules require; manufacturers choose all the others themselves. A “Best if used by” date marks when flavor and texture are at their peak. A “Sell-by” date helps the store rotate its stock, and once it passes you can still keep the food at home for its usual storage time. A “Use-by” date is the manufacturer's own pick for the final day of best quality.
For that reason, the storage times on this page start counting from the moment you open, cook or buy liquid egg substitute, not on the date stamped on the package: 3 days in the fridge. Food that was stored properly can still be good after a best-by date, while food that was handled carelessly can go bad long before it.
The best place for liquid egg substitute
Choose a middle shelf over the door, which warms up each time someone opens it.

Liquid egg substitute myths: fact or fiction?
- You got it!Not this time.
False. Food-poisoning bacteria seldom alter how food smells. Keep to the 3 days window and discard anything older.
- You got it!Not this time.
False. The freezer puts bacteria on hold rather than killing them. They start up again as the food warms, so let it thaw in the fridge, then cook or reheat it all the way through.
- You got it!Not this time.
False. FoodKeeper advises against freezing liquid egg substitute: the texture falls apart, or the thawed result can't be trusted to be safe.
- You got it!Not this time.
False. Each time the fridge is opened, the door heats up. Choose a middle shelf over the door, which warms up each time someone opens it.
- You got it!Not this time.
False. Certain bacteria produce toxins that heat cannot destroy. Reheating kills the bacteria themselves but leaves those toxins behind, so anything left out longer than 2 hours belongs in the trash.
