Why are red onions purple?

Red onions turn blue and purple because they contain a shade called anthocyanin. That tone responds with building blocks in your food, similar to magnesium and calcium. There are other antacid components, but these rarely end up in food.

Varieties of foods high in magnesium and calcium include vegetables, nuts, tofu, mixed greens, dairy, and most proteins. Red onions contain the color anthocyanin, which produces a blue-based red. So it can go from blue to purple to red, and when cooked, it can turn blue, especially if the last dish is antacid.

How Anthocyanin Works

Anthocyanin is available from a host of food sources, not just red onions or shallots, or red cabbage. It is also present in berries, dark rice, and surprisingly dark or purple carrots. In case you think it has to do with cyanide, don’t do it. It is completely different.

Anthocyanin is made up of “anthro” which means flower-based, and “cyanine,” as in cyan. If you remember your printer’s seemingly absurd request for ‘cyan’ when you need to print any shade, this is because cyan is an essential shade. Also, anthocyanin is basically found in flowers hence the ‘antho’ part.

The point is that this tone can appear in changed tones depending on the pH of the food. An exceptionally antacid food with this shade will appear blue, for example, blueberries or pea flower. In fact, the blue tea that turns purple, that one.

Acidic food

Extremely acidic food will appear red, such as red onion or cherries. A staple or center food will appear purple, like purple cauliflower.

You may have seen that some food sources are not completely blue or red, and purple can be somewhat blue or reddish.

Going back to anthocyanin, on red onions, it appears reddish in light of the fact that onions are generally acidic. When something soluble (from the opposite end of the gamut) comes in contact with this shade, it turns more towards blue. The more soluble the food, the bluer it becomes.

This is also why salty red onions take on that wonderful pinkish hue. The corrosive in vinegar causes the anthocyanin to lean more toward red, creating the pinkish tint that you see.
