How Long Do Liquid Egg Whites Last?
Liquid egg whites last 3 days in the fridge after opening. An unopened carton keeps about 1 week from purchase, or until its use-by date, and can be frozen for up to 1 year.
Liquid Egg Whites — opened
shelf life- Unopened: 1 week in the fridge
- Fresh: 2–4 days in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Liquid egg whites are separated, pasteurized whites sold in refrigerated cartons, sometimes with added color or seasoning in egg-substitute blends. Pasteurization kills Salmonella, which makes them safer than raw shell eggs, but it does not sterilize the product. Once the carton is opened, spoilage bacteria grow quickly in this protein-rich liquid, so the window is short.
How to store liquid egg whites
- Write the opening date on the carton the moment you break the seal; three days passes quickly and the printed date no longer applies.
- Pour out what you need and return the carton to the fridge at once, without letting the spout touch the bowl or pan.
- If you buy in bulk, put unopened cartons in the freezer on the day of purchase and thaw one at a time in the refrigerator.
- Freeze leftover whites from shell eggs in an ice cube tray, one white per well, then bag them for meringues and angel food cake.
How to tell if liquid egg whites have gone bad
- A sour, sulfur or fishy smell when the cap is removed; fresh liquid whites have almost no odor.
- A pink, green or iridescent tinge in the liquid, a sign of Pseudomonas bacteria.
- A cloudy, thick, stringy or lumpy consistency instead of a clear, loose, pale yellow liquid.
- A swollen or leaking carton.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Frequently asked questions
How long do liquid egg whites last after opening?
Liquid egg whites last 3 days after opening, according to USDA guidance for liquid egg products. Some brands print up to 7 days on the carton; the 3-day figure is the more cautious one. Keep them at 40°F (4°C) or colder and do not rely on smell to extend the time.
Can you freeze liquid egg whites?
Yes, an unopened carton freezes for up to 1 year. Thaw it in the refrigerator, never on the counter, shake well, and use it within 3 days. USDA advises against freezing cartons that have already been opened. Whites you separate at home can be frozen straight away.
Are carton egg whites safe to drink raw in a shake?
Pasteurized liquid egg whites are heat-treated to destroy Salmonella, so they carry far less risk than raw shell eggs, and they are what food-safety agencies suggest for uncooked recipes. Check that the carton says pasteurized, keep it cold, and stay within 3 days of opening. People at higher risk should still ask their doctor.
Are liquid egg whites good after the expiration date?
Treat the use-by date on liquid egg products as a firm limit rather than a suggestion. This is a highly perishable, low-acid food, and the bacteria that can grow in it may not change its look or smell. If the carton is past its date or has been open more than 3 days, discard it.
How many liquid egg whites equal one egg?
About 2 tablespoons (30 ml) of liquid egg whites equals the white of one large egg, and 3–4 tablespoons (about ¼ cup) replaces one whole large egg in most recipes. Carton whites whip into meringue less reliably than fresh ones, because pasteurization affects the proteins.
