Lemon juice is a versatile ingredient, but how long does it last in a plastic container? The answer depends on whether the juice is freshly squeezed or store-bought, and whether it has been opened. Freshly squeezed lemon juice will last about a day at room temperature and 3-4 days in the fridge in a sealed container. Store-bought lemon juice can be stored in the pantry if unopened, but once opened, it should be refrigerated and will last 6-12 months. Freezing lemon juice is also an option, which can extend its life by several months.
| Characteristics | Values |
|---|---|
| Freshly squeezed lemon juice life at room temperature | About a day |
| Freshly squeezed lemon juice life in the refrigerator | 2-4 days |
| Unopened bottle of lemon juice life at room temperature | 3-12 months |
| Opened bottle of lemon juice life in the refrigerator | 6-12 months |
| Lemon juice in the freezer | 6 months |

What You'll Learn
Freshly squeezed lemon juice lasts 3-4 days in the fridge
Lemon juice is a very acidic substance, often used as a natural preservative. However, lemon juice does go bad as it degrades. Freshly squeezed lemon juice will last about a day at room temperature and up to 3-4 days in the fridge when stored properly in an airtight container. The relatively short shelf life of fresh lemon juice means you'll need to use it quickly to avoid waste.
The spoilage process starts once the fluid is exposed to the air and microorganisms. Lemon juice is an ideal environment for yeast, mould, and bacteria to grow. This is why commercial lemon juices go through a thermal pasteurisation process before hitting the shelf. Pasteurisation kills any microorganisms that could be present in the juice, rendering it commercially sterile.
Store-bought bottled lemon juice typically contains additional preservatives and has been pasteurised. This process helps the lemon juice to stay shelf-stable while unopened. It also allows the lemon juice to stay fresh for longer once opened. Most store-bought lemon juice can last 6+ months after opening if stored properly.
To extend the shelf life of freshly squeezed lemon juice, you can freeze it. Lemon juice can be frozen in ice cube trays, allowing for easy portion control when you need to use it.

Store-bought lemon juice can last 6-12 months after opening
Lemon juice is a very acidic substance that is often used as a natural preservative. However, lemon juice does go bad as it degrades. Store-bought lemon juice can last 6-12 months after opening. This is because store-bought lemon juice typically contains additional preservatives and has been pasteurized. This process helps the lemon juice to stay stable while unopened and also allows the juice to stay fresh for longer once opened.
Store-bought bottled lemon juice should be stored in the same way as other juices. This means it should be kept in a cool, dark area, away from sources of heat. If stored in a clear plastic bottle, it should be kept away from light. The pantry is the perfect place, but a kitchen cupboard will also do. Once the bottle or container is opened, it should be kept tightly sealed when not in use and stored in the fridge for best results.
Lemon juice is sensitive to heat, direct sunlight, and air. Too much exposure and the freshness begins to fade. Lemon juice is also an ideal environment for yeast, mould, and bacteria to grow. This is why commercial lemon juices go through a thermal pasteurization process before hitting the shelf. Pasteurization kills any microorganisms that could be present in the juice, rendering it commercially sterile. The process also allows the juice to retain its attractive qualities, such as taste, smell, and colour, for consumers.
There are several signs that your lemon juice has gone bad. The first is a change in colour. Bad lemon juice will become darker and cloudy. If it no longer smells like fresh lemons, it should be thrown away. Spoiled juice loses its distinctive citrusy flavour and instead, tastes bitter.

Lemon juice can be frozen to extend its lifespan
Freezing lemon juice is a great way to preserve its vibrant flavour and ensure it doesn't turn sour. It is a convenient method to keep lemon juice on hand for recipes or to add to drinks. To freeze lemon juice, you can use ice cube trays, which allow you to thaw small portions as needed. Once the cubes are frozen, you can transfer them to a plastic bag or container for easier storage.
Another option is to freeze the lemons themselves before juicing them. This method can make the lemons last for three to four months. However, freezing whole lemons may affect their texture, making the pulp and juice a bit weird.
Additionally, you can freeze the lemon zest separately to have it ready for future baking projects. Freezing lemon juice or zest is an excellent way to extend the lifespan of lemons and ensure their freshness for a more extended period.
It's important to note that while freezing can extend the lifespan of lemon juice, it may not last indefinitely. The quality of the juice may degrade over time, and it is always good to use your best judgement before consuming any food item that has been frozen for an extended period.

Lemon juice can be canned and stored for years
Lemon juice is a versatile ingredient that can be used in a variety of dishes and drinks. It is also a great natural cleaner. While fresh lemon juice can be stored in a sealed container in the refrigerator for up to four days, it can also be frozen or canned to extend its shelf life.
Canning is a great way to preserve lemon juice for much longer periods. The high acidity of lemons means that lemon juice can be water-bathed canned, which is a simple process that only requires a few steps.
Firstly, you will need a large batch of fresh, firm lemons. Wash the lemons, cut them in half, and juice them. You can use any method to extract the juice, from a citrus juicer to good old-fashioned squeezing! You can strain the pulp or leave it in, but it may make the juice slightly bitter.
Next, prepare your canning equipment, including sterilized jars with lids. Bring the lemon juice to a low simmer in a separate pot. You want to warm up the juice, not boil it. Start filling your jars, leaving about a quarter of an inch of headspace from the top. Wipe the rims of the jars, place the lids on, and slightly tighten the rings.
Finally, place the jars in a water canner, ensuring they are covered by at least two inches of boiling water. The processing time will depend on your altitude. If you are at sea level (0-1,000 feet), boil the jars for 5 minutes. For altitudes between 1,001-6,000 feet, boil for 10 minutes, and for altitudes above 6,000 feet, boil for 15 minutes.
Once the processing time is up, carefully lift the jars out of the water and let them cool. Check that the jars have sealed by pressing on the center of the lid. If it doesn't move, your jar is sealed and ready for storage. If it pops up and down, the jar needs to be refrigerated.
Properly canned lemon juice can be stored on your shelf for up to two years, providing a convenient source of this versatile ingredient whenever you need it.

Lemon juice can be used as a cleaner when it's no longer consumable
Lemon juice can be stored in a plastic container or bottle and kept in a cool, dark area, away from direct sunlight and sources of heat. If the container is clear, it should be stored away from light. An unopened bottle can be stored in a pantry or cupboard. Once opened, the container should be kept tightly sealed and stored in a refrigerator. Lemon juice stored in this way will last for at least a couple of months and up to nine months.
Lemon juice that is no longer consumable can be used as a cleaner. It is a mild bleaching agent and has antibacterial properties due to its acidity. It can be used to remove stains from clothing, particularly white T-shirts and socks, but should not be used on coloured clothing. It can also be used to remove stains from kitchen surfaces and appliances, such as blenders and microwaves. Lemon juice can also be used to remove limescale caused by hard water. However, it is not suitable for cleaning countertops or floor tiles, and in these cases, a commercial cleaner or diluted bleach is recommended.
