Is it okay to leave orange juice unrefrigerated?

Orange juice is a staple beverage in many households. Its tangy, refreshing flavor makes it a popular choice for breakfast and beyond. But when it comes to storage, many people wonder: is it okay to leave orange juice unrefrigerated?

How long can orange juice be left unrefrigerated?

The short answer is: not long. Orange juice should always be refrigerated for optimal safety and quality. Here’s a more detailed look at how long orange juice can be left out at various temperatures:

  • Room temperature (68-77°F/20-25°C): 6-8 hours
  • Warm room (77-90°F/25-32°C): 2-3 hours
  • Hot car (>90°F/32°C): 1 hour or less

As you can see, warmer temperatures dramatically reduce the shelf life of unrefrigerated orange juice. After these time periods, the risk of bacterial growth and spoilage increases rapidly.

Why does orange juice need to be refrigerated?

There are two main reasons why orange juice requires refrigeration:

  1. It contains natural sugars. Orange juice has a high sugar content. Sugars allow bacteria and yeast to thrive if left unrefrigerated.
  2. It has a low acidity. Acidity helps preserve foods. Although orange juice contains some citric acid, its pH level is not low enough to prevent microbial growth for more than several hours without refrigeration.

Additionally, refrigeration helps maintain the flavor and vitamin content of orange juice. Heat and oxygen degrade the delicate flavors and nutrients in juice over time.

What happens if you drink orange juice left unrefrigerated?

Drinking orange juice that has been left out too long can cause unpleasant, or even dangerous, side effects. Here are some risks of drinking unrefrigerated orange juice:

  • Unpleasant taste. The flavors and aroma can become stale, bitter, and unpleasant.
  • Vitamin degradation. Heat and sunlight degrade vitamin C and folate over time.
  • Bacterial growth. Lactic acid bacteria, acetic acid bacteria, and molds can grow, causing off-tastes and acidity.
  • Foodborne illness. Bacteria like salmonella, E. coli, and listeria can all thrive in warm, unrefrigerated juice.

Symptoms of foodborne illness include nausea, vomiting, stomach cramps, and diarrhea. Vulnerable populations like pregnant women, children, and the elderly are at highest risk. But even otherwise healthy adults can become sick from drinking bad orange juice.

How to tell if orange juice has gone bad

Watch for these signs that your OJ is no longer safe to drink:

  • Smells rotten, fermented, or moldy
  • Appearance is cloudy or has particles floating in it
  • Sour, bitter, or “off” taste
  • Fizzing or bubbling inside the container
  • Slimy or slippery texture
  • Mold growing on the surface

Orange juice that displays any of these characteristics should be discarded. Don’t take risks with your health.

Does orange juice last longer in the fridge door or middle shelf?

For maximum freshness, store orange juice on a refrigerator shelf rather than in the door. The frequent temperature fluctuations caused by opening and closing the door can degrade juice more quickly. A shelf in the middle of the fridge maintains a more constant, colder temperature.

Here’s how long properly refrigerated orange juice typically lasts in the fridge or freezer:

Storage Method Shelf Life
Refrigerator Shelf 7-10 days
Refrigerator Door 5-7 days
Freezer 9-12 months

Of course, always check for signs of spoilage no matter where you store your OJ. Don’t go by the expiration date alone.

Tips for storing orange juice correctly

Follow these best practices for keeping orange juice fresh and safe:

  • Buy small containers. Less juice equals less time it will sit in the fridge before being finished.
  • Seal containers tightly. Cap or close juice bottles securely to prevent oxygen exposure.
  • Don’t return unused juice to the original container. This can introduce bacteria. Pour excess into a clean container.
  • Store juice as far back in the fridge as possible. The back tends to be coldest.
  • Keep fridge below 40°F (4°C). Optimal temperature for juice is 34–37°F (1-3°C).
  • Don’t store in door. Use a shelf in the middle of the fridge for most consistent temperature.
  • Freeze extras. Frozen juice concentrate lasts 9-12 months.

Can you freeze orange juice?

Yes, you can safely freeze orange juice to extend its shelf life. Here are some freezing tips:

  • Freeze juice concentrate or freshly squeezed juice. Don’t freeze reconstituted juice from concentrate. It can separate and become watery.
  • Leave 2-3 inches of headspace in rigid containers to allow for expansion.
  • Use plastic freezer bags for more flexible storage options. Remove excess air before sealing.
  • Add some lemon juice or vitamin C powder before freezing. This helps preserve color and nutrient levels.
  • Thaw frozen juice overnight in the fridge before using.
  • Use within one week after thawing for best quality and food safety.

With proper precautions, frozen orange juice retains its flavor and nutrition for 9-12 months. It’s a great way to stock up and avoid last minute runs to the grocery store!

Can you refrigerate reconstituted orange juice?

It’s best to avoid refrigerating reconstituted orange juice from frozen concentrate. Here’s why:

  • The texture can become watery and separated.
  • Loss of fresh orange flavor and aroma.
  • Nutrient levels decrease faster.
  • Bacterial growth occurs more rapidly.

Instead, try one of these alternatives:

  • Make only as much juice as you can drink in one sitting.
  • Freeze extra reconstituted juice in ice cube trays, then use within 2 days.
  • Store concentrated juice in the fridge, and make single servings to drink fresh.

If you do refrigerate already made juice from concentrate, use within 2 days for safety and optimal quality.


Orange juice should never be left unrefrigerated for more than a couple hours, as it provides an ideal environment for microbial growth. Drinking juice that has been left out too long can result in illness. Refrigerating orange juice, ideally on a central fridge shelf, keeps it fresh and safe for 7-10 days. For minimal food safety risks and great taste, always store orange juice chilled.
