What Makes The Purple Podded Pole Beans Purple?
They contain a natural group of chemicals called anthocyanins. It’s what gives the purple color to the bean. Anthocyanins are also what make roses and also geraniums red, as well as cornflowers and delphiniums blue.
Not yellows as well as oranges, though; those shades come from carotenoids, which likewise are in charge of specific reds in plants. With beets and bougainvilleas, the red comes from yet one more all-natural pigment, called betacyanin.
Get back to anthocyanins. Just how does an anthocyanin make one vegetable red make and another one blue?
Acidity Of The Purple Podded Pole Bean
The acidity of the cell sap seems to be the key here. Anthocyanins change shades with any changes in acidity.
Keep in mind, the green color, which is still present but covered up by the anthocyanin.
A comparable thing takes place when you cook red cabbage. It transforms to “colorless” after some time. You can also expect purple broccoli, purple asparagus, purple tomatillos, even purple peppers to lose their purple color after cooking. Red peppers seem to stay red, though, because carotenoids provide their red shade.
Purple’s Peculiar Purposes
It may appear crazy to grow a purple vegetable if it is most likely to turn green anyway after you cook it. It’s not as if that purple shade does anything for flavor.
In nature, though, anthocyanins have a purpose. Such as bring in bugs to blossoms for pollination. They also safeguard plants from ultraviolet radiation, which is why you discover purple in more than a few plants. Carrot “shoulders” exposed to sunlight for long enough even turn purple once in a while.
