Why Do Potatoes Turn Green?

Potatoes are a staple in many diets around the world, but have you ever noticed that they can sometimes turn green? This is a common occurrence, and it’s important to understand why it happens and how to prevent it.

What Causes Potatoes to Turn Green?

Potatoes turn green when they are exposed to light. This is because the potato produces a natural chemical called chlorophyll. Chlorophyll is the same chemical that gives plants their green color. When potatoes are exposed to light, the chlorophyll is produced and the potato turns green.

The green color is an indication that the potato has been exposed to light for too long. This can happen when potatoes are stored in a place that is too bright, such as near a window or in direct sunlight. It can also happen when potatoes are stored in a place that is too warm, such as near a stove or in a warm room.

The green color is not harmful, but it does indicate that the potato has been exposed to light for too long. This can cause the potato to become bitter and inedible.

How to Prevent Potatoes from Turning Green

The best way to prevent potatoes from turning green is to store them in a cool, dark place. This can be a pantry, cupboard, or even a refrigerator. It is important to keep the potatoes away from direct sunlight and any other sources of light.

It is also important to store potatoes in a place that is not too warm. The ideal temperature for storing potatoes is between 45 and 50 degrees Fahrenheit.

What to Do if Potatoes Have Already Turned Green

If potatoes have already turned green, it is important to discard them. The green color is an indication that the potato has been exposed to light for too long and is likely to be bitter and inedible.

It is also important to check other potatoes that were stored in the same place. If they have also turned green, it is important to discard them as well.
