Does Lime Juice Go Bad?

The Role of Acidity and Oxidation

Lime juice is acidic, so it might seem like it lasts a long time, but it actually has a limited shelf life like all other juices. Citric acid slows bacterial growth but doesn’t stop oxidation or spoilage once the juice is exposed to air.

• Oxidation weakens quality: Vitamin C breaks down fast when exposed to air and light.

• Fresh juice spoils quickly: Freshly squeezed lime juice can lose freshness in just 24–48 hours.

• Air exposure shortens life: The more oxygen hits the juice, the faster the flavor fades.

• Bacteria can still grow: Even with citric acid, homemade lime juice can support harmful bacteria.

• Lime juice depends on storage: Proper storage is key to preserving taste and food safety.

Pasteurization vs Fresh-Squeezed: Key Differences

The life of lime juice depends on how it’s processed. Store bought lime juice is usually pasteurized and sealed, while fresh squeezed juice has no preservatives and breaks down faster.

• Store bought juice lasts longer: Unopened, it may last several weeks past the printed date.

• Opened bottle spoils faster: Once opened, bottled lime juice go bad within 2–4 weeks.

• Preservatives extend life: Store bought versions include stabilizers to prevent spoilage.

• Fresh squeezed = natural process: No additives means flavor fades and safety risks rise quickly.

How Can You Tell When Lime Juice Is Bad?

Common Red Flags to Watch For

Spoiled lime juice gives off clear signs, even if it’s still within the expiry date. Before you put it in salad dressings, marinades, or other citrus-based recipes, always use your senses.

• Smells funky or sour: A strong fermented or off odor means the juice has gone bad.

• Color is darker than usual: Fresh lime juice should be pale and clear, not brown or cloudy.

• Texture is unusual: Sediment, cloudiness, or separation can signal spoilage.

• Taste is dull or bitter: If the bright flavor is gone, so is the freshness.

• Cap shows mold: Mold growth around the seal is a definite sign to toss the whole bottle.

When It’s No Longer Safe to Use

Lime juice can become unsafe even with small changes. Don't just trust the expiration date, especially if you don't store it right, things can go bad earlier.

• Opened too long = risk: Even in the fridge, fresh juice lasts only a few days.

• Expired lime juice isn’t trustworthy: Bacteria may be present even if it looks fine.

• Homemade juice is most fragile: It lacks preservatives and has a short safe window.

• Store lime juice correctly: A sealed container in the fridge is essential.

• If in doubt, throw it out: It’s not worth risking food poisoning or an upset stomach.

What Is the Shelf Life of Lime Juice?

Fresh vs Bottled: A Timeline Breakdown

How lime juice is made and how it is stored affects how long it lasts. Bottled juice lasts longer than fresh juice, especially when the bottle is not opened and the juice is kept in the fridge.

• Fresh lime juice: Lasts 1–3 days in the fridge.

• Fresh lemon juice: Similar shelf life and spoilage signs.

• Unopened bottled juice: Keeps for several weeks to months in a dark place.

• Opened bottle = 2–4 weeks: Must be refrigerated and tightly sealed.

• Freeze lime juice: Extends shelf life up to 3–4 months in an ice cube tray.

Storage Best Practices That Really Work

Storing lime juice the right way helps maintain its best quality and prevents early spoilage. Whether it’s fresh or bottled, proper handling is essential.

• Keep in the fridge: Always refrigerate after opening to maintain freshness.

• Use a sealed container: Air exposure shortens the life of lime juice.

• Freeze leftovers: Use an ice cube tray to portion and preserve extra juice.

• Avoid plastic wrap for long-term use: Not ideal for juice, only for whole limes.

• Label frozen juice: Track how long it's been stored.

• Keep out of direct sunlight: Store in a dark place for a long shelf life.

Is It Okay to Use Expired Lime Juice?

“Best By” vs “Use By” – What They Really Mean

The juice doesn't become unsafe right after the printed date. Quality dates and safety limits are not the same thing, and knowing this will help you avoid citrus juice that has gone bad.

• Best by date = quality: Juice may still be safe, but flavor and freshness decline.

• Use by date = safety: After this point, food safety becomes a concern.

• Store bought lime juice lasts longer: Especially unopened and kept in a dark place.

• Opened bottle = shorter timer: Always check smell, color, and taste first.

• Homemade lime juice has no buffer: Use it quickly, it’s not designed for long storage.

Can Expired Lime Juice Make You Sick?

Lime juice that is past its expiration date might not always make you sick, but it can make you uncomfortable. It's best to throw this juice away as soon as it starts to show signs of going bad, just like other juices.

• Risk of food poisoning: Harmful bacteria can form even if mold isn’t visible.

• Upset stomach is common: Especially with older juice stored unrefrigerated.

• Not worth the gamble: Discard juice that smells funky or tastes flat.

• Even if refrigerated, it degrades: Time still affects quality and safety.

• Check the whole bottle: Look at the seal, liquid, and date before use.
