How long can orange juice sit out before it goes bad?


Orange juice is a popular breakfast drink that many people enjoy first thing in the morning. It’s tasty, refreshing, and provides a good dose of vitamin C. However, orange juice is perishable and can spoil if left out too long at room temperature. So how long can you leave orange juice sitting out before it’s no longer safe to drink? In this article, we’ll take a look at how long orange juice lasts both refrigerated and unrefrigerated, and provide tips for storing it properly.

How Long Does Orange Juice Last Refrigerated?

When stored properly in the refrigerator, orange juice can maintain good quality and fresh taste for about 5 to 7 days after opening. The exact shelf life depends on a few factors:

Factor Effect on Shelf Life
Container Juice will last longer in an airtight container compared to a pitcher.
Pulp content Pulp-free juice lasts a bit longer than juice with pulp.
Acid content Juice with higher acidity has more preservative qualities.

To maximize freshness, store orange juice in a tightly sealed container toward the back of the fridge, where temperatures are coldest. Keep the container away from strong odors as orange juice can absorb other smells.

How Long Can Orange Juice Sit Out at Room Temperature?

Once opened, orange juice should not be left out at room temperature for more than 2 hours. The warmer conditions allow microbial growth and oxidation to occur much more rapidly compared to refrigeration.

Here are some general guidelines for maximum times orange juice can be left unrefrigerated:

Room Temperature Max Time
Up to 70°F (21°C) 2 hours
71–90°F (22–32°C) 1 hour
Above 90°F (32°C) 30 minutes

At higher temperatures, the window of time before spoilage accelerates. Bacteria grow rapidly above 90°F.

How to Tell if Orange Juice Has Gone Bad

It’s always best to discard orange juice if there’s any question of safety based on time left out. But here are some common signs that indicate orange juice has spoiled and should be thrown out:

  • Changes in appearance: The juice appears cloudy, has pulp separation, contains particles, or has a changed color.
  • Changes in smell: An “off” odor can indicate microbial growth or oxidation.
  • Changes in taste: Flat, tangy, bitter, metallic, or acidic tastes signal spoilage.
  • Formation of bubbles, fizzing, hissing, or mold.

Don’t detect any obvious signs? Taste a small sip to check for changes – spoiled orange juice will immediately taste off. Still uncertain? When in doubt, throw it out.

What Causes Orange Juice to Go Bad?

There are two main mechanisms that cause orange juice to spoil: microbial growth and chemical oxidation.

Microbial Growth

All orange juice contains some natural yeasts and bacteria from the fruit. Refrigeration helps slow microbial growth. But over time, exposure to warmer temperatures allows microbes like mold and bacteria to rapidly multiply, causing spoilage. Common culprits include:

  • Yeasts – Cause bubbly fermentation.
  • Molds – Lead to slimy film or fuzz.
  • Lactic acid bacteria – Result in sour, tangy tastes.
  • Acetic acid bacteria – Give a vinegary smell.


Exposure to oxygen leads to chemical changes in the juice over time. Enzymes in the juice react with oxygen, causing discoloration and degradation of flavor, nutrients, and quality. The juice ends up with a stale, cardboard-like taste. Refrigeration helps slow this process.

Tips to Extend the Life of Orange Juice

To get the most freshness out of your orange juice, be sure to:

  • Store juice in the fridge immediately after opening.
  • Transfer to an airtight container such as a mason jar.
  • Keep container away from light to prevent nutrient degradation.
  • Don’t return unused juice to the original container – this introduces bacteria.
  • Check juice for any signs of spoilage before drinking.
  • Keep refrigerated after pouring a glass.
  • Finish juice within 3-5 days of opening for peak quality.

With proper refrigerated storage, orange juice can retain good flavor for up to a week past the “best by” date on the container. But remember, time sitting out at room temperature should be minimized. If in doubt, err on the side of caution – a sour stomach just isn’t worth the risk.

Can You Freeze Orange Juice to Extend the Shelf Life?

Yes, freezing is an effective way to extend the shelf life of orange juice way beyond refrigerated storage. Here’s how it works:

  • Freshly squeezed or store-bought orange juice can be frozen.
  • Pour juice into freezer-safe airtight containers, leaving 1⁄2 to 1 inch of headspace.
  • Lay plastic wrap directly on surface of juice to prevent oxygen exposure.
  • Freeze juice for up to 3-6 months.
  • Thaw in fridge before using.
  • Use thawed juice within 5-7 days.
  • Juice may have some separation – shake before drinking.

Freezing stops any microbial growth and slows oxidation reactions. Thawed orange juice retains much of its original nutritional value and flavor. The vitamin C content can degrade over prolonged freezing, so juice is best consumed within 6 months.

Can You Make Orange Juice Last Longer With Preservatives?

Some additional preservatives can be used to extend the shelf life of homemade or fresh-squeezed orange juice:

  • Ascorbic acid – This is a form of vitamin C. It acts as an antioxidant and adds acidity to help control microbial growth. Use 1/4 teaspoon powdered ascorbic acid per cup of juice.
  • Citric acid – Found naturally in citrus fruits, citric acid works as a preservative and adds tart flavor. Use 1/4 to 1/2 teaspoon per cup of juice.
  • Potassium sorbate – This inhibits mold and yeast growth. Use 1/4 teaspoon potassium sorbate per cup of juice.

However, store-bought orange juice is already treated for safety and preservation purposes. Adding extra preservatives is unnecessary if the container instructions are properly followed. Most store-bought juice already includes additive preservatives like ascorbic acid on the ingredient list.

Is Moldy Orange Juice Safe to Drink if Heated?

No, do not consume any orange juice that has visible mold or other signs of spoilage. Heating or boiling spoiled orange juice does not make it safe for drinking.

The toxins produced by mold and bacteria cannot be reversed. Any spoiled juice should be discarded. Mold often develops when juice is left out too long at room temperature. Prevention is key – refrigerate juice after pouring and discard if expired.


Orange juice has a limited shelf life, so it’s best consumed within about a week of opening. To maximize freshness, store juice refrigerated in an airtight container and avoid leaving it out more than 2 hours at room temperature. Signs of spoilage include changes in appearance, smell, taste, and texture. Freezing can significantly prolong orange juice storage. With proper handling, orange juice can retain good flavor, color, and nutrition well past the “best by” date. Just be vigilant about temperature control and food safety.
