Red onions get their color from a pigment called anthocyanin. This pigment is also found in other fruits and vegetables like blueberries and eggplants. So what does this pigment do?

Well, it’s thought to have antioxidant properties which can help protect our cells from damage. Additionally, some research has shown that anthocyanin may also help to lower blood pressure and reduce inflammation. Interestingly, the color of an onion can actually change depending on the pH level of the soil it was grown in.

So if you notice that your red onion has a bit more purple or blue hues to it, that’s perfectly normal! No matter what color they are on the outside, all onions share the same basic nutritional profile. They’re a good source of fiber, vitamins C and B6, and manganese.

So whether you choose a red onion for its vibrant color or simply because you like the taste, know that you’re getting a nutritious vegetable either way.

Why Are Red Onions Not Called Purple Onions?

Why is Red Onion Called Red Onion When It’S Purple

Have you ever wondered why red onion is called red onion when it’s actually purple? The answer is quite simple. When red onions are grown, they are exposed to sunlight for a longer period of time than other types of onions.

This exposure to sunlight causes the skin of the red onion to turn red. However, the flesh of the red onion is still white. So, even though the skin of the onion is red, the flesh is what gives it its name.

Why are Red Onions Red

Have you ever wondered why red onions are red? The answer lies in their anthocyanin content. Anthocyanins are water-soluble vacuolar pigments that may appear red, purple, or blue depending on the pH of the solution they are in.

They belong to a parent class of molecules called flavonoids and are responsible for the bright colors in many fruits and vegetables. In onions, the anthocyanins are located in the outermost layer of the epidermis. When an onion is cut, enzymes within its cells convert phenols into quercetin.

Quercetin then reacts with oxygen to produce quercetin oxide, which is colorless. However, when quercetin oxide comes into contact with anthocyanins, it turns red. This is why slicing a red onion will cause it to turn white – because all of the quercetin oxide has reacted with the anthocyanins!

Interestingly, not all onions contain anthocyanins. White and yellow onions get their color from carotenoids – another type of pigment molecule found in plants. So how do farmers get red onions?

They breed them from other red onions! Over time, through selective breeding, farmers have developed varieties of onion that contain high levels of anthocyanins. If you want to learn more about flavor chemistry or pigments in plants, check out this video: https://www.youtube.com/watch?
