Is orange juice good if it sits out overnight?


Many of us have accidentally left a glass or carton of orange juice sitting out on the counter overnight. When this happens, you may wonder if it’s still safe and good to drink that OJ, or if you should just toss it out to be on the safe side. In this article, we’ll take a comprehensive look at how sitting out affects orange juice and whether or not it remains healthy and tasty if left unrefrigerated overnight. We’ll also provide tips on how to tell if your orange juice has gone bad and when it’s best to throw it out.

How Sitting Out Affects Orange Juice

Freshly squeezed orange juice contains natural sugars and water, which make it prone to spoilage if left unrefrigerated. Here are the key changes that take place in orange juice when it sits out at room temperature overnight:

Time Elapsed Effects on Orange Juice
2-4 hours The orange juice starts losing its fresh, just-squeezed taste. Subtle changes in flavor and mouthfeel become noticeable.
6-8 hours The orange juice tastes more bitter and metallic. The consistency becomes slightly thicker and pulpier.
10-12 hours The orange juice smells and tastes spoiled with an vinegary, fermented flavor. Mold may start visibly growing.
24 hours The orange juice smells and tastes rotten with a very sour, unpleasant flavor. Mold is usually visible. Bacteria levels are unsafe.

As you can see from the table, orange juice left sitting out at room temperature goes through gradual but noticeable changes in smell, taste, and texture. The most dramatic changes happen after about 8-12 hours sitting out unrefrigerated.

Is It Safe to Drink Orange Juice that Sat Out Overnight?

So is orange juice still safe to drink if you accidentally left it out on the kitchen counter overnight? Here are the key factors to consider:

1. Temperature

The temperature of your home makes a big difference. If your home is around 70°F, bacterial growth in orange juice left out overnight will be much faster than if your home was cooler, say 60°F. The warmer the orange juice, the higher the risk it became unsafe after sitting out too long.

2. Acidity Level

Orange juice has a low acidity level around 3.5-4.0 pH. This makes it more prone to bacterial growth when sitting out unrefrigerated, compared to juices with higher acidity like pineapple, lemon, or tomato juice.

3. Container Size

Bacterial growth occurs faster in larger containers of orange juice. An entire 64 oz carton will likely be unsafe after 8-12 hours out, while a small 6-8 oz glass may still be tolerable for drinking.

4. Pulp Content

Pulp provides favorable conditions for bacterial growth, so pulpy orange juice becomes unsafe more quickly than filtered, pulp-free orange juice when sitting out overnight.

5. Product Type

Freshly squeezed orange juice has a shorter shelf life than commercially packaged orange juice. The pasteurization process extends the shelf life of store-bought OJ.

Given all these risk factors, we recommend:

– Orange juice left out for less than 8 hours can be risky to drink

– Orange juice left out 8-12+ hours should not be consumed and should be thrown out

Do not drink orange juice that you suspect may be spoiled due to sitting out overnight. The potential risks simply outweigh any benefits.

How to Tell if Orange Juice Left Out Overnight Is Bad

Trust your senses when determining if orange juice is still good after sitting out overnight:


Fresh orange juice has a bright, citrusy smell. Discard orange juice that smells sour, vinegary, or unpleasant in any way.


Toss orange juice that has visible mold floating on top or sediment at the bottom of the container. Cloudiness or tiny bubbles throughout are also red flags.


The best test is to cautiously take a small sip. Spit it out immediately if you detect bitterness, sourness, metallic flavors, or anything “off.” Don’t drink any more!


Fresh OJ has a smooth, liquid consistency. Discard orange juice if the texture seems syrupy, thick, slimy, or has an odd mouthfeel.

Trust your instinct – if your orange juice tastes or smells bad, err on the safe side and throw it out. Don’t take risks with your health.

Tips to Extend the Shelf Life of Orange Juice

To get the most out of your OJ and avoid having to toss it after sitting out overnight, here are some storage tips:

Storage Tips Benefits
Store freshly squeezed orange juice in airtight containers in the fridge Minimizes air exposure to prolong freshness
Fill containers to the top Leaves less empty space for oxygen where microbes can grow
Never store orange juice at room temperature Keeps juice chilled below unsafe bacterial growth zones
Consume orange juice within 3-5 days Prevents any substantial deterioration in quality or safety
Avoid returning orange juice to the fridge after serving Prevents contamination and quality reduction from temperature fluctuations

Following these best practices will help ensure your OJ stays fresher for longer after opening. Taking simple preventative steps can give you peace of mind that your juice won’t go bad or become unsafe to drink if you happen to accidentally leave it out overnight.

The Bottom Line

So, is orange juice still good if left out overnight? Our recommendation is to not take any risks. Orange juice left sitting out at room temperature for more than 8 hours is unsafe to drink due to the potential growth of mold, bacteria, and other microorganisms.

Toss any OJ that was left unrefrigerated overnight and has an off smell, taste, appearance, or texture. Don’t drink it. This will protect you from foodborne illnesses.

Instead, store your orange juice properly in sealed containers in the fridge and consume it within 3-5 days of opening. Follow the storage best practices provided above to get the most freshness and flavor from your OJ. And remember – when in doubt, throw it out! Your health and safety is too important to chance.
