A pigment from red cabbage could help turn your favorite foods blue Apr. 9, 2021 , 4:15 PM It’s not that hard to make a natural blue dye. Just take a red cabbage, cut it into pieces, and boil it. What you get is a purple broth that turns bright blue when you add some baking powder. Children have been doing this for decades, but researchers have struggled to turn this or similar natural blues into a stable and abundant colorant one that could be used to naturally dye your favorite candies, sodas, or ice creams. Now, a team says it has found a way and the key lies in the humble cabbage itself.

Natural blue color from red cabbage could replace artificial food dye

Natural blue color from red cabbage could replace artificial food dye Dan Avery For Dailymail.com © Provided by Daily Mail MailOnline logo Blue is the world s most popular color but the hue rarely appears in nature, so manufacturers have had to resort to artificial dyes and chemicals to create blue food. That could soon change, now that a naturally occurring blue pigment has been discovered in red cabbage. Scientists with the Mars candy corporation found traces of anthocyanin - a pigment that gives red, purple, blue and black foods their color - that was coded blue. They were able to increase that amount by treating the cabbage s red-colored anthocyanins with a designer enzyme that turned them blue.
