Anthocyanins exist in all tissues of a plant and may appear in the roots, stems, leaves, flowers, and fruits (though not all at once).With purple beans, the pigments primarily show up in the flowers, which gradually give way to purple-tinged pods.(In fact, red cabbage makes a good indicator in pH experiments at home.).This happens when the red side was exposed to more sunshine, spurring a chemical reaction in the plant cells that produces more pigments.If you want to minimize color loss, you can blanch them, singe them on the grill, or toss them into a stir-fry at the end for a couple minutes.You can also try to increase the acidity (thus retaining some of the anthocyanins) by briefly soaking the beans in lemon juice or vinegar before cooking them.This trick works best for recipes that already have a bit of tanginess to them, like lemony pastas, Thai-style noodles, or rice bowls with citrus shrimp.As you may have noticed in the kitchen at one point or another, not all purple vegetables turn green when they’re exposed to heat.When they’re cooked (typically by steaming, roasting, or boiling), they may veer more violet since water has a neutral pH, but more or less keep their color.(Conversely, blue potatoes may take on reddish tones — appearing more purple — if cooked with acidic ingredients.).When these vegetables are cooked past the stage of being crisp-tender, they’ll only fade from purple to lavender because the acylated anthocyanins don’t undergo as drastic of a change.Acylated anthocyanins are so stable, in fact, that their pigments have been studied as a potential (and more natural and healthful) replacement for synthetic dyes such as FD&C Red No. .
