Why Is My Cucumber Dark Green Inside? Is It Safe To Eat?

Have you ever cut into a cucumber, expecting pale green flesh, and been met by a surprisingly dark color? This is a worrying event when it happens, but the important question is whether the cucumber is okay to use.

If your cucumber is dark green inside, there are a few possible explanations. The first is that the cucumber has been frozen during storage, and the second is that some varieties are naturally a darker green. If the dark green is accompanied by mushiness, this indicates that the cucumber is going off.

Why Do Cucumbers Turn Dark Green?

A cucumber that has dark green in it may have been affected by a couple of different things, but the most likely explanation is that it has got partially frozen. If the cucumber gets pushed to the back of your fridge and ends up leaning against the coldest part, it is quite common for it to freeze. This will lead to dark green, slightly transparent skin. 

Similarly, if you grow cucumbers outside and you have a hard frost unexpectedly, you may find that they turn dark green inside, particularly in spots that have touched the ground or another cold surface. The whole cucumber may turn dark green inside if it is too cold out. Usually, areas that have been cold damaged will stay firm and good to eat. 

There are a few other potential causes too. For example, some people say that a calcium deficiency can cause the cucumber cells not to form properly, and this results in dark green flesh inside the skin. Other possible reasons include:

  • The type of cucumber
  • Bruising on the cucumber
  • The cucumber going bad.

These are less likely to result in dark skin inside, but they are possibilities, so bear them in mind if you find your cucumber has darker spots in it and you are sure it hasn’t been damaged by cold.

Can You Eat A Cucumber That Has Turned Dark Inside?

If you want to eat a cucumber but you find that the central flesh is dark, you should check whether the cucumber has spoiled. There are quite a few ways to tell, and the first involves checking if the cucumber is mushy. Press lightly on the flesh, and see if it squashes under your hand. Cucumbers tend to be reasonably soft, but they shouldn’t collapse under light pressure.

Next, check whether the cucumber smells fresh. A good cucumber should have a pleasant, slightly sweet scent, while a spoiled one will often smell vinegary or strongly of mold. You may need to cut the cucumber open to release the scent, but this should also help you to determine whether it is mushy or not.

If you still aren’t sure, cut off a small slice of the cucumber and taste it. If it tastes strange, there is a high chance that it isn’t safe to eat anymore, so you should throw the rest away. However, if it still tastes like a normal cucumber, it should be fine to eat.

You can generally eat a darkened cucumber once you have checked these things but do always look for signs of spoilage before you consume it. Although a moldy cucumber is not likely to make you very sick if you eat it, it’s not worth the risk of stomach ache or diarrhea.

Can I Stop My Cucumber From Going Green?

The best way to prevent greenness in your cucumber is to keep it away from the back of the fridge and make sure it doesn’t freeze. Cucumbers need to be refrigerated in order to stay fresh, but because they have a lot of moisture in them, they freeze very readily. Freezing will do permanent damage to the tissues and make them glassy and dark.

You may be able to prevent your cucumber from freezing by putting it in a container so that it cannot get pushed to the back. Make sure your fridge temperature is not too low, too, and this should further decrease the freezing risk.

If you are growing your own cucumbers, make sure that you protect the plants from frost damage, and harvest any fruits that are ready if you are expecting cold weather. Most plants won’t survive freezing.

Should I Cut Off The Green Part?

You can cut off the dark green part of the cucumber if you choose to, but there is no particular need to do this. As long as the flesh is firm and tastes good, it should be perfectly safe for you to eat. 

Conclusion

Dark areas inside your cucumber tend to be the result of the vegetable getting too cold. The cell walls get damaged, and this makes them appear darker. You can usually avoid this by putting your cucumber in the crisper drawer of your fridge and preventing it from freezing.
