Question

What are the differences in properties of a white onion and a red onion?

Answer 1

The ingredients of all onions, Allium cepa varieties are the same in quality but differ in quantity.

E,g.:Shallots have six times the phenolic content than the variety with the lowest content (Vidalia). Western Yellow onions have 11 times more flavonoids than Western Whites, the onion with fewest flavonoids :

So they also differ in taste:

Red onions tend to be medium to large in size and have a mild to sweet flavor. They are often consumed raw, added for color to salads, and grilled or lightly cooked with other foods.

White onions are a type of dry onion that has a pure white skin and a sweet, mild white flesh. This onion is used in Mexican foods or complementing the flavors of other ingredients.
