When it comes to preparing potatoes, it’s not uncommon to notice that they turn brown after being cut and exposed to the air. This process is called oxidation and can leave some people wondering whether oxidised potatoes are safe to eat. As someone who enjoys cooking, I have often found myself in this situation and have done some research to find out the answer.
The good news is that oxidised potatoes are safe to eat. While the brown colour may not look as appealing, it doesn’t affect the taste or texture of the potato. In fact, some dishes such as Polish grey dumplings are intentionally made with oxidised potatoes. However, it’s still important to take some precautions to prevent potatoes from turning brown and to ensure that they’re safe to eat. In this article, I’ll share some tips on how to prevent potatoes from oxidising and answer some common questions about the safety of oxidised potatoes.
What are Oxidised Potatoes?
As a recipe developer, I have come across oxidised potatoes several times. Oxidised potatoes are potatoes that have turned brown after being cut or peeled. This happens because of a natural reaction that occurs when the potato is exposed to air. The reaction is known as oxidation, and it is caused by an enzyme called polyphenol oxidase.
What do Oxidised Potatoes Look Like?
Oxidised potatoes have a brownish or greyish tint on the surface. The discolouration can be quite noticeable, and it can make the potatoes look unappetising. The texture of the potato may also change, becoming softer or mushy in some cases.
How Do You Fix Oxidised Potatoes?
While oxidised potatoes may not look very appealing, they are still safe to eat. However, if you prefer your potatoes to look fresh and vibrant, there are a few things you can do to fix them. Here are some tips:
- Soak the potatoes in water: Soaking the potatoes in cold water for about 15 minutes can help remove some of the discolouration. Make sure you dry the potatoes thoroughly before cooking them.
- Add some lemon juice or vinegar: The acid in lemon juice or vinegar can help prevent oxidation. Add a tablespoon of lemon juice or vinegar to a bowl of water and soak the potatoes for about 15 minutes. Dry them thoroughly before cooking.
- Cook the potatoes immediately: If you are not planning to use the potatoes right away, store them in water until you are ready to cook them. This will help prevent further oxidation.
In conclusion, oxidised potatoes are safe to eat, but they may not look very appetising. By following the tips above, you can fix oxidised potatoes and make them look fresh and vibrant again.
Are Oxidised Potatoes Safe to Eat?
As a food item that is commonly consumed all over the world, potatoes are known for their versatility and nutritional value. However, when potatoes are exposed to the air, they can turn brown due to the oxidation process. This raises the question of whether oxidised potatoes are safe to eat or not. In this section, I will answer this question and provide some additional information related to potato consumption.
When Should You Not Eat Potatoes?
Potatoes that are not stored properly or are exposed to certain conditions can become unsafe to eat. For example, potatoes that have sprouted or have green patches on their skin should not be consumed. Additionally, potatoes that have been stored for more than a week can develop a bitter taste and should be discarded.
Can You Eat Potatoes That Have Sprouted?
Potatoes that have sprouted should not be consumed as they contain a toxic substance called solanine. Solanine can cause digestive problems, headaches, and even paralysis in extreme cases.
Are Week-Old Potatoes Safe to Eat?
Potatoes that have been stored for a week or longer can develop a bitter taste due to the breakdown of starch into sugar. While they may not be harmful to consume, they may not taste as good as fresh potatoes.
Is It Safe to Eat Potatoes with White Mold?
Potatoes with white mould should be discarded as they can contain harmful toxins. White mould can also indicate the presence of other harmful bacteria and fungi.
Is It OK to Eat Grey Potatoes?
Grey potatoes are safe to eat as long as they do not have a foul odour or slimy texture. Grey potatoes are usually the result of exposure to air, which causes oxidation.
Can You Eat Blight Infected Potatoes?
Blight infected potatoes should not be consumed as they can contain harmful toxins. Blight is a fungal disease that affects potatoes and can cause the potatoes to rot.
Can You Eat Potatoes with a Green Tinge?
Potatoes with a green tinge should be avoided as they can contain solanine. Green potatoes are usually the result of exposure to light, which causes the production of chlorophyll.
In conclusion, oxidised potatoes are safe to eat as long as they do not have any other signs of spoilage. However, it is important to store potatoes properly and discard any potatoes that have sprouted, have green patches, or have a foul odour or slimy texture.
Why Do Potatoes Oxidise?
As someone who loves to cook, I have often wondered why potatoes turn brown when they are peeled or cut. After doing some research, I discovered that the discolouration is due to a process called oxidation.
What Causes Discolouration in Potatoes?
When a potato is cut or peeled, the flesh is exposed to air, which contains oxygen. The oxygen reacts with the potato’s enzymes and phenolic compounds, causing them to turn brown. This process is accelerated by heat, which is why cooked potatoes often turn brown more quickly than raw ones.
The discolouration of potatoes is not harmful, and oxidised potatoes are safe to eat. However, the browning can affect the taste and texture of the potato, making it less appealing.
There are several ways to prevent potatoes from oxidising. One way is to keep the potatoes submerged in water until you are ready to cook them. This prevents the potatoes from coming into contact with air and slows down the oxidation process. Adding a little bit of lemon juice or vinegar to the water can also help to prevent browning.
Another way to prevent oxidation is to cook the potatoes immediately after peeling or cutting them. This will stop the enzymes and phenolic compounds from reacting with the oxygen in the air.
What Happens When Potatoes Go Bad?
As a potato ages, it may start to show signs of spoilage. In this section, I will cover various ways in which a potato can go bad, and what you should look out for.
What Do Potatoes Look Like When They Go Bad?
When potatoes go bad, they may start to shrink, wrinkle, and develop soft spots. They may also become discoloured or develop dark spots. These are all signs that the potato is no longer fresh and may have started to spoil.
What Does Mould Look Like on a Potato?
Mould on a potato may appear as black, green, or white spots. If you notice mould on a potato, it is best to discard the potato as the mould can spread quickly and contaminate other potatoes.
What is Early Bright Disease in Potatoes?
Early Bright Disease is a bacterial infection that affects potatoes. It can cause the potatoes to become discoloured and develop dark spots. If you notice signs of Early Bright Disease, it is best to discard the affected potatoes.
Why Did My Boiled Potatoes Turn Black?
If your boiled potatoes turn black, it is likely due to a chemical reaction between the iron in the water and the potatoes. This reaction can cause the potatoes to turn black or blue. While the potatoes may not look appetising, they are still safe to eat.
How Long Can Potatoes Sit Before Turning Brown?
Potatoes can start to turn brown within a few minutes of being peeled or cut. To prevent browning, you can place the potatoes in a bowl of water with a little bit of lemon juice or vinegar.
How Do You Know If Potatoes Are Bad in the Fridge?
If potatoes have been stored in the fridge for too long, they may start to sprout or develop a greenish tint. This is due to exposure to light. While these potatoes may not be harmful to eat, they may not taste as good as fresh potatoes.
Does One Mouldy Potato Ruin the Rest?
Yes, one mouldy potato can contaminate the rest of the potatoes in the bag or container. It is best to discard any potatoes that have mould on them.
What is the White Fuzz on My Potatoes?
The white fuzz on potatoes is likely due to a fungal infection. While the potatoes may still be safe to eat, it is best to discard any potatoes with signs of fungal growth.
How Long Does It Take for a Potato to Mould?
Potatoes can start to mould within a few days to a few weeks, depending on the storage conditions. To prevent mould growth, store potatoes in a cool, dry place away from direct sunlight.
How to Store Potatoes

What is the Best Way to Store Potatoes?
The best way to store potatoes is in a cool, dark, and dry place. Ideally, the temperature should be around 45 to 50 degrees Fahrenheit. A basement is an excellent place to store potatoes, but a kitchen cupboard or closet works just as well.
It’s important to make sure the area where you store your potatoes is dry and has good ventilation. Moisture and lack of air circulation can cause potatoes to rot quickly.
Will Potatoes Oxidise in the Fridge?
Potatoes can oxidise in the fridge, causing them to turn brown. However, this doesn’t mean they’re unsafe to eat. Oxidation occurs when potatoes are exposed to the air for an extended period, such as when they’re cut. To prevent this, store cut potatoes submerged in water in the fridge for up to one day. Add something acidic to the water, such as lemon juice or vinegar, for extra protection.
How Do You Keep Cut Potatoes from Turning Grey?
Cut potatoes can turn grey when exposed to air. This doesn’t mean they’re unsafe to eat, but they may not look as appetising. To prevent this, keep cut potatoes submerged in water until you’re ready to cook them. Adding something acidic to the water, such as lemon juice or vinegar, can help keep them from turning grey.
Can You Peel Potatoes and Freeze Them?
Yes, you can peel potatoes and freeze them. However, it’s essential to blanch them first to prevent them from turning brown. To blanch potatoes, boil them for 3 to 5 minutes, then immediately transfer them to an ice bath. Once they’re cooled, drain them and freeze them in an airtight container or freezer bag.
In conclusion, storing potatoes correctly is crucial to ensure they stay fresh and safe to eat. Keep them in a cool, dark, and dry place with good ventilation, and make sure to store cut potatoes submerged in water with something acidic added. You can also peel and freeze potatoes, but blanch them first to prevent them from turning brown.
