Can out-of-date lemon juice make you sick? (+3 Tips)

In this article, we will answer the question “Can out-of-date lemon juice make you sick?”, and how to tell If the lemon juice has gone bad?

Can out-of-date lemon juice make you sick?

Yes, consuming out-of-date lemon juice can make you sick if it is spoiled. (1) Though lemon juice has a very low pH due to its high acidity, it can be contaminated by microorganisms.. 

If you drink spoiled lemon juice, you will experience symptoms of food poisoning. The most common symptoms are diarrhea, vomiting, nausea, and stomach pain. (1)

If the juice has passed its best-by date but it doesn’t have any signs of spoilage, it is safe to consume. So, it is very important to know how to detect if the orange juice is spoiled.

What are the factors that influence lemon juice spoilage?

The main factors that cause lemon juice to spoil are exposure to air, light, room temperature, enzymatic activity, and microbial growth.

The exposure to oxygen triggers the degradation of ascorbic acid and the non-enzymatic browning of lemon juice. (3)

Flavor and color are affected by the degradation of ascorbic acid, and this is the major deteriorative reaction that takes place during the storage of lemon juice. (2)

The microorganisms that can proliferate into lemon juice are the ones that have a high tolerance to acid and those that are osmophilic. (4)

What are the risks of consuming expired lemon juice?

According to the FDA, drinking spoiled lemon juice can cause vomiting, diarrhea, abdominal pain, and flu-like symptoms, such as fever, headache, and body aches (5).

Consuming dangerous foodborne bacteria will usually cause illness within 1 to 3 days of eating the contaminated food. (5)

It is also important to note that properly stored and unopened lemon juice is usually safe to consume even after the expiry date, as long as it does not show any signs of spoilage.

How to properly store lemon juice?

Here are some recommendations for properly storing lemon juice

  1. An unopened container or unrefrigerated lemon juice should be stored in a cool and dark place away from heat sources like sunlight or a stovetop.
  2. After opening the container, it must be kept in the fridge with a tight seal.
  3. Lemon juice that is sold refrigerated should be kept in the fridge at all times and tightly sealed.
  4. Homemade lemon juice squeezed out of fresh lemons must be placed in the refrigerator to preserve its freshness, and shouldn’t be left sitting out for more than 2 hours. (6) 

Can you freeze lemon juice?

Yes, you can freeze lemon juice. Freezing has its own pros and cons. It might deteriorate the quality of juice, but that can be restored almost fully by proper mixing/shaking so the pulp and water unite. 

Frozen storage of freshly squeezed lemon juice results in a longer shelf life than refrigerated. However, once thawed, the orange juice has a refrigerated shelf life of 2 months. (7)

Freezing is recommended for long-term storage as frozen orange juice may last up to several months if stored properly. 

The best way to defrost the frozen juice is by refrigerating it, but if you thaw it by microwaving it or putting it in lukewarm water try to consume it immediately.

How long does lemon juice last?

The speed at which it degrades depends on whether it is freshly squeezed or purchased and packaged. Fresh juice spoils quicker than bottled juice.

Juice of Fresh Lemons

Freshly squeezed lemon juice can go bad too. If kept refrigerated, freshly squeezed lemon juice lasts for about 6 days and can last for 12 months if frozen (7). Freshly squeezed lemon juice can go bad pretty quickly when left at room temperature.

Bottled Lemon Juice

Because bottled lemon juice is loaded with preservatives, an unopened bottle will last for not more than 12-18 months. As for opened lemon juice, the contents are safe to consume within 2 months. (7)

It is also important to note that properly stored and unopened lemon juice is usually safe to consume even after the expiry date, as long as it does not show any signs of spoilage.

How to tell if lemon juice has gone bad? (3 tips)

To find out if lemon juice is spoiled, you should look at three things: its appearance, its odor, and how it tastes. If it has become dull or darker in color, it should be thrown away. Also, if the scent or flavor has changed considerably, proceed in the same way.

Even though lemon juice is a highly acidic substance, it is susceptible to deterioration and, if left unprotected, degrades rapidly, especially when stored at room temperature. (2)

Some signs of spoiled lemon juice are: 

  1. Color: Lemon juice will become darker due to non-enzymic browning. (5) A noticeable sign of spoilage is spotting clouds of bacteria developing in the juice or a change in color. This can be produced by a bacteria that can grow into an acidic medium called Alicyclobacillus acidoterrestris. (2)
  2. Smell: The smell is no longer citrusy and fresh, it will smell bitter and yeast-like. 
  3. Taste: When lemon juice begins to spoil, it will lose its citrusy flavor and will taste bitter.
