New Cyan Blue Food Color Obtained from Red Cabbage
Researchers converted anthocyanin blue from a tiny fraction of red cabbage extract into a primary product
A natural brilliant blue coloring has been discovered by an international team of researchers including chemists at the University of California, Davis. The new cyan blue, obtained from red cabbage, could be an alternative to synthetic blue food colorings such as the widely used FD&C Blue No. 1. The work is published April 7 in Science Advances.
"Blue colors are really quite rare in nature - a lot of them are really reds and purples," said Pamela Denish, a graduate student working with Professor Justin Siegel at the UC Davis Department of Chemistry and Innovation Institute for Food and Health.
