Does Lemon Juice Go Bad?

Lemons are known as one of the best natural preservatives. Whenever there is lemon juice in something, we know that it won’t go bad too quickly.

But what about lemon juice itself? Does it go bad? Lemon juice does have a limited shelf life, be it freshly squeezed or bottled lemon juice from the supermarket.

Freshly squeezed lemon juice lasts way shorter than lemon juice sold in bottles. While there are a few more differences between fresh and bottled lemon juice, the general rules of storing them are the same.

If you don’t store lemon juice properly, it will quickly lose its refreshing properties. Not only that. Bad lemon juice has the ‘potential’ to ruin an entire dish.

Commercially manufactured lemon juice that is sold unrefrigerated can be stored in the panty before being opened.

Keep the unopened bottle of lemon juice in a cool and dark area, away from heat sources and light. A kitchen cabinet will also work well for storing unopened lemon juice so long as it is away from the oven.

Once you open the bottle, lemon juice should be refrigerated. You should keep the lid tightly sealed at all times to prevent the contact of the juice with air.

As store-bought lemon juice contains added preservatives, some people think that it will do well at room temperature too even after opening. While store-bought lemon juice may last at room temperature for some time after opening, its quality will quickly degrade. The fridge, on the other hand, will significantly extend its shelf life.

Freshly squeezed lemon juice should be refrigerated at all times. This also refers to store-bought lemon juices that are sold in the refrigerated section. These are typically the ones that claim to be all-natural lemon juice concentrates without any additives.

The general storage rule remains the same: keep lemon juice in a container that you can tightly seal.

Commercially manufactured lemon juice always comes with a ‘Best by’ date. But considering that these juices are simply mixtures of water, lemon juice, and preservatives, they can last longer than the date indicated on the label so long as you keep the bottle unopened.

An unopened bottle of lemon juice stored in a cool and dry area will last up to 6 months past its ‘Best by’ date.

Surprisingly, opening and refrigerating store-bought lemon juice doesn’t decrease its shelf life. You can keep a well-sealed bottle of lemon juice in the fridge for 6 to 12 months past the ‘Best by’ date.

Things are different with freshly squeezed lemon juice. It has a way shorter shelf life.

Kept in the refrigerator, in a tightly sealed container, fresh lemon juice has a shelf life of 3 to 5 days.

If you use lemon juice often and don’t want to spend time on squeezing fresh lemon juice every time you need it, then buying bottled lemon juice is your best option. It keeps longer and is convenient for everyday use.

It should be mentioned, however, that many people prefer freshly squeezed lemon juice as its flavor is brighter and fresher.

So, it is a matter of preference. The important thing is that you know how to store lemon juice and how long it lasts no matter which kind you are using.

One ice cube generally equals two tablespoons. Keep these measurements in mind when using frozen lemon juice.

If you are going to use the lemon juice cubes for drinks, you can thin down the juice with water and only then freeze it.

Frozen lemon juice will maintain its best quality for 3 to 4 in the freezer. However, if you have not managed to use up your frozen lemon juice cubes, you can continue using them as they will keep safely in the freezer for much longer.

You can thaw lemon juice by letting the cubes sit in the fridge. Alternatively, you can use the microwave or leave the cubes stored in the freezer bag under running cold water.

As for freshly squeezed lemon juice, things will happen much faster. You will notice significant changes in the color, smell, and taste of freshly squeezed lemon juice after a few days of storing it in the fridge.

Even if the citrus juice seems to be good, don’t use it if you have had it for more than 5 days.

Using lemon juice contaminated with bacteria or toxins may result in food poisoning and other health issues. If you are having any doubts about the freshness and safety of your lemon juice, discard it.
