Lemon juice is a popular ingredient in many recipes, from salad dressings to cocktails. But how long does fresh lemon juice last, and how can you store it properly to maximize its shelf life? Here’s everything you need to know.
Fresh vs. Commercial Lemon Juice
Fresh lemon juice will last up to four days in the refrigerator if stored correctly in an airtight container. Commercial lemon juice, on the other hand, can last much longer, typically between 3–12 months, depending on how it is stored.
Commercial lemon juices undergo a thermal pasteurization process, which helps to extend their shelf life. They may also contain added preservatives. Freshly squeezed lemon juice doesn’t have these protections, so it spoils more quickly.
How Long Does Fresh Lemon Juice Last?
- Room Temperature: Fresh lemon juice should not be left at room temperature for more than a day.
- Refrigerator: Fresh lemon juice can last up to 4 days in the fridge if stored in a sealed container. Some sources say it will only last for 2-3 days.
- Freezer: If you have more fresh lemon juice than you can use in a few days, consider freezing it. You can pour the juice into an ice cube tray and freeze it for up to three months.
How to Store Fresh Lemon Juice
The best way to store fresh lemon juice is in an airtight container in the refrigerator. This minimizes its exposure to oxygen and microorganisms, which can lead to spoilage. It is also advisable to store it towards the back of the fridge where it’s coldest for maximum freshness.
How Long Does Bottled Lemon Juice Last?
- Unopened: An unopened bottle of commercial lemon juice can last for 3–6 months in the pantry or 6–12 months in the fridge.
- Opened: Once opened, bottled lemon juice should be stored in the refrigerator and can last for 6-12 months.
Even with preservatives, bottled lemon juice can still go rancid in the fridge.
Signs of Spoilage
Lemon juice is an ideal environment for yeast, mold, and bacteria to grow. If you’re unsure whether your lemon juice is still good, look for the following signs of spoilage:
- Strange odor
- Change in color
- Mold
- Bitter or off-putting taste
If you notice any of these signs, discard the juice.
Tips for Using Lemons
- To maximize the shelf life of fresh lemon juice, store lemons in the refrigerator.
- When you have an abundance of lemons, consider juicing them all at once and storing the juice in the freezer.
- Use the lemon peels to make a three-ingredient sorbet.
Conclusion
Lemon juice can be a useful ingredient to have on hand, but it is important to store it properly and use it in a timely manner. Fresh lemon juice will only last a few days in the refrigerator, while commercial lemon juice can last much longer. If you’re unsure whether your lemon juice is still good, look for signs of spoilage before using it.
