Updated October 14, 2016. Don't panic if you have the occasional green stool (green poop). In most cases, there is a reasonable explanation for a green bowel movement that doesn't involve a health problem. A green poop could still be within the range for what is considered to be a normal stool.
Betacyanin is the nitrogen-containing red pigment of beets (Beta spp.) and other Chenopodiaceae. Betacyanins are also present in flowers of Cactaceae, Portulacaceae, and even some fungi. Betacyanin is commercially used as a natural food dye.he bright red pigment that gives beets their characteristic color is betacyanin. When some people eat beets, their bodies are unable to break down the betacyanin and as a result, their urine becomes pink. Most of the beets grown in Wisconsin are red beets but you can find pink, purple, white, and yellow beets.
In dry form betanin is stable in the presence of oxygen. The color of betanin depends on pH; between four and five it is bright bluish-red, becoming blue-violet as the pH increases. Once the pH reaches alkaline levels betanin degrades by hydrolysis, resulting in a yellow-brown color. Betanin is a betalain pigment, together with isobetanin, probetanin, and neobetanin. Other pigments contained in beet are indicaxanthin and vulgaxanthins. Sources and uses. Betanin is usually obtained from the extract of beet juice; the concentration of betanin in red beet can reach 300â600 mg/kg.
