Does Lemon Juice Go Bad?
Yes, lemon juice can go bad. Fresh-squeezed lemon juice lasts 2-4 days refrigerated. Bottled lemon juice lasts 6-12 months unopened and 6 months opened if refrigerated. Signs of spoilage include darkened color, cloudy appearance, off smell, and mold.
Key Takeaways
- Fresh-squeezed lemon juice has a short shelf life because it lacks the preservatives found in commercial products.
- Organic bottled lemon juice may have shorter shelf life due to fewer preservatives.
- Slightly darkened lemon juice is safe but may have diminished flavor.
Explanation
Fresh-squeezed lemon juice has a short shelf life because it lacks the preservatives found in commercial products. It begins to lose vitamin C and fresh flavor within hours at room temperature and should be refrigerated promptly.
Commercial bottled lemon juice contains preservatives (usually sulfites or citric acid) that extend shelf life significantly. Unopened bottles last well past their best-by dates. Once opened, refrigeration is essential.
Both fresh and bottled lemon juice should be stored in airtight containers in the refrigerator. Exposure to air causes oxidation that degrades flavor and nutrients. For longer storage, lemon juice freezes well in ice cube trays.
Things to Know
- Organic bottled lemon juice may have shorter shelf life due to fewer preservatives.
- Slightly darkened lemon juice is safe but may have diminished flavor.
- Lemon juice concentrate has a longer shelf life than regular bottled juice.
