Plant-Based Liquid Egg

Plant-based liquid egg is a short-window fridge product — most sources put it at roughly 4–7 days once opened, though we couldn’t confirm an exact figure directly from Just Egg’s own FAQ. Freezing works even though the brand doesn’t officially recommend it — Just Egg’s own materials state plainly that it’s a refrigerated product not intended for freezing.

How long does plant-based liquid egg last in the fridge?

We weren’t able to find a single confirmed number from Just Egg’s own FAQ for how long an opened bottle lasts — sources we checked range anywhere from 4 to 10 days, without agreement. Given that spread, and that USDA’s general guidance for traditional liquid egg products (a related but not identical category) recommends using opened liquid egg promptly, we’d lean toward the more conservative end of that range — treating it similarly to fresh dairy rather than assuming the longer estimates apply.

Unopened, refrigerated bottles are good until the date printed on the package. As with any perishable, don’t leave an opened bottle out of the fridge for more than two hours per USDA’s Danger Zone guidance.

Can you freeze plant-based liquid egg?

Just Egg’s own materials are direct about this: “JUST Egg is a refrigerated product, and we do not recommend freezing it.” That said, many people successfully freeze it anyway — usually in an ice cube tray for easy portioning — and report good results after thawing in the fridge, even though it’s against the manufacturer’s official recommendation. If you do freeze it against their guidance, expect some texture change and don’t refreeze once thawed.

Note that some specific product lines — like pre-cooked, folded plant-based egg patties — are sold frozen and meant to be kept that way; that’s a different product from the standard liquid bottle discussed here.

How to tell if plant-based liquid egg has gone bad

• Smell: a sour, sulfurous, or distinctly “off” odor
• Color: significant darkening or an unusual color shift
• Texture: separation or a slimy consistency that doesn’t recombine when shaken
• Packaging: a bloated or swollen bottle — discard without tasting

Storage tips

• Keep it refrigerated at all times — this product is never shelf-stable, unlike some plant-based milks
• Store toward the back of the fridge, not the door
• Shake before each use, and reseal tightly right after pouring
• Write the open date on the bottle so you’re not guessing later

Why isn’t this covered by USDA?

FreezerOrFridge.com’s 732 core pages pull their storage times from the USDA FoodKeeper database, which tracks traditional shell eggs and liquid egg products in detail but doesn’t currently include plant-based liquid egg — a newer product category that hasn’t made it into that federal dataset yet.
