Are Oxidized Potatoes Safe To Eat?
Oxidized potatoes are safe to eat. Due to the natural starch in potatoes, they turn brown, grey, or black when exposed to oxygen. This is called oxidation. Oxidized potatoes are safe to eat and do not lose their flavour or texture.
Turning does not affect the taste and texture of potatoes, and you can use oxidized potatoes as they are edible. Oxidized potatoes are completely safe to eat; the process does not affect the taste or aroma of the vegetable.
When do the potatoes get oxidised?
While this process is one of the healthiest ways to cook oxidized potatoes, boiling can cause the potatoes to brown when peeled. It will quickly brown after peeling the potato and exposing the starchy white part to the air. When potatoes are chopped, especially into smaller slices, like brown mashed potatoes, most of the starch oxidises, causing the potatoes to turn grey.
Flipping is a harmless natural reaction ideal for cooking and eating potatoes, even if they have turned grey. While it’s not good to flip, the texture and taste of the potatoes haven’t changed, and they can still be eaten.
Just like squeezing a lemon over sliced apples, a little lemon juice or white vinegar in a bowl of sliced potatoes will help to avoid grey tints.
|Apply acid to the potatoes
|Adding acids such as lemon or vinegar to potatoes in water will not add their flavor to the potatoes but reduce the pH level of oxidation
|Cover the potatoes in the water
|Cover the potatoes in a bowl full of water. This will slow down the oxidation process but not stop it
|Place the potatoes in the salted water
|Try putting the potatoes in salted water. This will help keep the oxidation process at bay
It is also necessary to reduce oxygen availability; soak the sliced potatoes in water as the potatoes turn brown in the air. Small cuts, such as diced potatoes, soak into the water faster, so it’s best to soak them in cold water for a short while, for example, while preparing other ingredients.
Shredded potatoes for pancakes will brown very quickly, so you may need to put a lot of shredded potatoes in cold water when you’ve finished shredding the remaining potatoes.
If you need to peel, slice, or slice your potatoes beforehand, the best way to prevent them from browning is to soak them in cold water. The best way to prevent this is to soak raw potatoes in cold water, drain well, and pat dry before cooking.
From the moment it’s peeled, you’ll have time to cook the peeled potato or store it properly before it takes on an unwanted colour. If you wait until the potatoes are cooked, you can cut the peeling process in half.

It is much better to boil the potatoes for 3-4 minutes, drain the water, let them steam and dry for a few minutes, then pour over the oil and seasonings and cook for 30-45 minutes.
Partially cooking potatoes by boiling or frying allows the potatoes to be frozen without discolouration or mushy formation. Because potatoes release molecules into the boiling water when boiled, the same effect can cause the boiling water to darken over time.
While cooking in cold water can help prevent dark spots on boiled potatoes, it’s not guaranteed to prevent oxidation. To prevent oxidation, you can place the cut potato cubes in water or brine before cooking. Whether you’re making potato salad, hash browns or frying potatoes, you must prevent oxidation.
Oxidation occurs when raw, peeled potatoes are exposed to the oxygen in the air, and this is what causes peeled potatoes to turn brown. With raw potatoes, sweet potatoes, apples, avocados, etc., when a raw potato is peeled and exposed to oxygen, an oxidation process begins, turning it brown/grey. When these starches are exposed to oxygen, they undergo oxidation, causing the potato to take on a greyish or brownish hue.

In reaction with environmental oxygen, the potato changes the colour of the potato to a greyish or brownish tint. After the potatoes are removed from the cooking water, the chlorogenic trivalent acid mixes slowly with oxygen, creating a colour ranging from grey to black, purple to bluish.
The turning point comes because the natural sugars in the potato break down into alcohol and carbon dioxide. Scientifically, however, the breakthrough happens when your potato comes into contact with the oxygen in the air, which is impossible when the tubers are immersed in water, whose oxygen is strongly bonded to hydrogen and does not oxidize the potato.
Soaking potatoes in lemon water before putting them in a slow or slow cooker can kill this enzyme. You can cut the potatoes the night before; however, put the pieces in water and add lemon juice (1 tablespoon per litre) so they don’t oxidize.
If you store potatoes in the refrigerator for any reason, they will keep for three to four weeks but take on a sweet taste when cooked. Properly stored frozen potatoes will keep their best quality in the refrigerator for about 12 months but are generally safe to eat afterwards. Frozen potatoes are stored permanently frozen at 0°C or indefinitely if stored properly, and the packaging is undamaged.
According to Eat By Date, baked potatoes can last up to 5-7 days when refrigerated properly. It is not recommended to store potatoes in the refrigerator, as low temperatures slow down the respiration rate.
If you cut a sweet potato in half and leave the cut open for a few days at room temperature, you will notice that the potato will heal on its own.
Cutting a sweet potato won’t speed up the spoilage process, but the exposed skin will dry out if you don’t soak it in water. Too much starch can prevent the potatoes from cooking evenly and create a chewy or sticky texture on the outside of the potatoes.
Boiled potatoes are a great way to get healthy carbohydrates, but oxidation often results in unsightly brown potatoes. The onset can quickly lead to unsightly browning, which may be more pronounced in some potato varieties.
How to fix an Oxidized potato?
To lower the pH of potatoes, you might use a spray of lime juice or white vinegar in the bowl with the potatoes. This will inhibit oxidation and grey hues on potatoes. This is a natural reaction; cooking and eating potatoes is fine, even if they have turned grey.
Why do potatoes oxidize?
It is normal for potatoes to oxidize and turn brown when exposed to fresh air. This is because they contain a high quantity of starch that goes through the oxidation process upon exposure to oxygen. Despite the brownish colour of the potatoes due to oxidation, they are safe to consume or use in your cooking.
Can oxidized potatoes make you sick?
No, eating oxidized potatoes cannot make you sick. Oxidation is a natural reaction after peeling your potatoes and exposing them to the air. Though the brownish skin may be off-putting, it doesn’t make the potatoes unsafe to consume. You can use them in your cooking even if they turn brown or grey.
