The Science of Potatoes: Will Cooked Potatoes Turn Brown?

The answer to the question of whether cooked potatoes will turn brown is yes, they will.

This happens because when potatoes are cooked, their starch granules break down and release an enzyme called polyphenol oxidase.

This enzyme causes the potato to turn brown when it comes into contact with oxygen.

While the discoloration may not be appealing, it is harmless and there is no need to worry about eating a brown potato!

Will potatoes turn brown in the fridge?

Cooking Reaction

Don’t be worried when refrigerated potatoes begin to turn brown in the course of cooking.

The browning is a result of another reaction which doesn’t render the potatoes unfit for consumption.

After a couple of hours in cold weather potato starch begins to convert into sugar.

When you cook these potatoes the sugar caramelizes and browns.

If you’re still not convinced, try this experiment: Cut two raw potatoes into pieces, and place them in separate bowls of water.

Leave one bowl of potato-water on the countertop and put the other in the fridge.

After a day or so, check on both bowls of potatoes.

The ones that were stored at room temperature will have developed an unappetizing grayish color, while the refrigerated potatoes will be nice and white.

The next time you’re prepping dinner and reach for some spuds that have been hanging out in your fridge, don’t panic if they’ve started to turn brown.

Those taters are still good to go.

This is a common cooking question, and one that has a simple explanation.

When potatoes are stored in cold temperatures, like the fridge, their starch begins to convert into sugar.

So when you cook them, the sugar caramelizes and browns.

Potatoes can be soaked in water or coated with olive oil to stop their browning.

Both olive oil and water help in reducing the oxygenation.

However, water is better because it assists in removing some starches in the potato.

This makes the potato less likely to brown when exposed to air.

Olive oil does have some benefits though. It can help keep potatoes from drying out as well as add flavor.

The bigger the pieces of potato will last, the longer they’ll stay in the water.

Can I leave cut potatoes in water overnight?

Cut potatoes shouldn’t be soaked for more than over a period of time.

If you keep potatoes in water for longer than an hour, let them cool before refrigerating.

Be sure to not soak them longer than overnight.

Once they’ve been soaked, potatoes begin to lose their shape and taste.

If you’re looking to speed up the potato-cutting process, soaking them overnight can help.

Soaking potatoes in water overnight helps to loosen the skin, making them easier to peel.

It also helps to remove any dirt or debris that may be on the surface of the potato.

So, if you’re short on time, soaking your potatoes overnight can be a helpful time-saving measure.
