Opened orange juice is generally good for about 7 to 10 days if stored properly in the refrigerator. After opening, refrigeration slows spoilage, but the juice should be consumed within this timeframe to avoid a sour smell, color changes, or mold development. Leaving orange juice out at room temperature drastically reduces its safety, with spoilage beginning in as little as 2 hours.
Shelf Life After Opening
- 7 to 10 days in the refrigerator is the typical safe period for commercial orange juice after opening.
- 2 hours at room temperature is the maximum time before spoilage risk increases significantly.
Signs of Spoilage
- Sour or vinegary smell
- Change in color to darker or lighter hues
- Presence of mold on the surface
- Bottle distortion due to gas production by microorganisms
Additional Notes
- Freshly squeezed orange juice spoils quicker—usually within 2 to 3 days refrigerated.
- Always keep the lid tightly closed to slow oxidation and bacterial contamination.
- Store on a lower shelf in the fridge rather than the door to maintain consistent cold temperature.
Thus, for optimal safety and taste, consume commercial orange juice within a week to 10 days after opening and avoid leaving it out at room temperature for more than two hours. Fresh-squeezed juice should be consumed even faster, within 2-3 days refrigerated.
