How long do lemons last?

In this short study, we shall provide a solution to the question, “How long do lemons last?”. We will also discuss the shelf life of the product and the best ways of storing lemons.

How long do lemons last?

The following table shows an estimated shelf life of cut and whole lemons under different storage conditions.

Whole10 days (1)10-21 days (1)8-12 months (11)
Cut2 hours (10)5 days (3)8-12 months (11)

Upon peeling and cutting, the outer protective layer is stripped away, revealing the inner fresh cells that are abundant in water sugars, and organic acids. 

The release of nutrients through this process encourages the growth of microorganisms, while the damaged tissue serves as an entry point for establishing a microbial colony. (3)

What are the factors that affect the shelf life of lemons?

The main factors that affect the shelf life of lemons are temperature, humidity, and handling;

  • Storage temperature: Is the most crucial environmental factor influencing the post-harvest lifespan of fresh fruits, primarily due to its significant impact on the rates of biological reactions, including respiration (5,6). 
  • Humidity: The lemons must be kept in a relatively dry environment. An environment too dry will lead to water loss, and an environment with too high humidity may lead to condensation and the enhanced growth of pathogens (7). 
  • Handling: For lemons that are going to be cut, it is important to wash them properly and manipulate them with clean hands and utensils to avoid microbial contamination due to unhygienic conditions. (4)

How to Tell If Your Lemons are bad?

There are a couple of indications that point out that your lemons have gone bad. You should consider the appearance, texture, and smell of the lemons.


If you spot a mold or other type of microbial growth on your lemons, then it means that your oranges have gone bad and the best thing you can do is to get rid of them. 

If you notice fuzzy or discolored patches, it indicates spoilage. Be careful as toxins produced by molds (i.e., mycotoxins) could be very dangerous for your health. (8)

Moreover, you should check for any significant color changes, if you spot some discoloration or brown specks on your lemons, that is an indication that your lemon is spoiled.

In addition, a spoiled lemon might have dehydrated and wrinkled outer skin, indicating that it has lost its moisture. 


A lemon that feels soft and mushy, then it may be a sign that the lemon is starting to spoil. It’s important to remember that the more a lemon ripens, the softer it gets.

If you start noticing changes in the texture and hardness of your lemon, then it’s safe to assume that it won’t be long until the lemon is bad. 


If you smell something foul, musty, or something that does not quite feel like the lemon itself or if the tangy smell of the lemon has weakened then it is the indication of a bad lemon and you should get rid of it.

Spoiled lemons may emit a fermented, musty, or rotten odor. If your lemon has mold on it, you should not smell it, since mold produces mycotoxins, and if you inhale lemon’s mold, those mycotoxins enter your body and they can make you ill. (9)

How to properly store lemons?

According to the Food and Drug Administration, lemons, like other perishable fresh fruits and vegetables, should be stored in a clean refrigerator at a temperature of 40°F or below. (4)

Fresh raw whole lemons can be stored in a cool, dry, and dark corner of the pantry but if you want to prolong their shelf life, then it is recommended to store them properly in the fridge. 

To ensure food safety, it is essential to maintain a clear separation of raw meat, poultry, and seafood, as well as the kitchen utensil used for handling these products, from fruits and vegetables that are intended to be consumed raw (4).

If you have peeled, cut, or sliced lemons, you have to refrigerate them. The best is to place them in a freezer bag or airtight container. If using a resealable plastic bag, squeeze out the air before sealing it. 

To ensure the safety of produce, you can contribute by making informed purchasing choices: 

  • Opt for produce that shows no signs of bruising or damage.
  • When purchasing pre-cut, bagged, or packaged produce, select only items that are refrigerated or kept surrounded by ice.
  • Remember to pack fresh fruits separately from raw meat, poultry, and seafood when bringing them home from the market (4). 

How to extend the shelf life of lemons?

You can extend the shelf life of lemons by refrigerating or freezing them. Here are the factors that you need to consider.

Do lemons need to be refrigerated?

Yes, lemons do need to be refrigerated to extend their shelf life. Lemons last for 10 days at room temperature from the date of purchase if stored properly. (1).

Raw whole lemons last for about 10-21 days when they are properly refrigerated from the date of purchase (1).

Cut/sliced lemons last for about 5 days when they are properly stored in the fridge at 40°C. (3)

Once fruits are cut, sliced, or chopped, they should be refrigerated in covered containers or frozen in plastic freezer containers. (2)

Can you freeze lemons?

Yes, you can freeze lemons. Freezing lemons will increase their shelf life by many months.

You can freeze whole or segmented lemons. Freezing is generally suitable for preserving most fruits; however, the quality of the frozen product may vary  depending on factors such as the type of fruit, its stage of maturity, and the packaging method. (4)

Generally, the flavor is well retained by freezing preservation. Texture may be softer than that of fresh fruit. (4)

The best way is to first wash the lemons in cold water and pat them dry using paper towels. Peel the lemons and try to remove as much pith as you can. Divide the lemons into portions or separate all the slices. 

Put them in a freezer bag, remove the excess air from it, and freeze it.
