欧宝体育What's your favorite color? If you say "blue," you're in good company. Blue far outstrips all other color preferences globally.

Blue dye in red beets

No matter how many people like to look at it, blue is a hard color to draw from nature. As a chemist studying the modification of natural products to solve technical problems, I realized the need for a safe, non-toxic and cost-effective blue dye. So my PhD my student BarbaraFreitas - Dorr and I have devised a method for converting red beet pigments into blue compounds that can be used in a variety of applications. We call it BeetBlue.


A natural source of blue

Blue is closely related to nature, mainly because it reflects in the sky and water. But blue pigments are less common in living organisms than other colors.


Many birds' feathers are blue, not because they produce pigment, but because the microscopic structure of their feathers filters light. This physical phenomenon is very interesting, but difficult to use in ordinary applications.




Plants rarely produce blue. When they do so, their pigments rarely remain stable after extraction. The same is true for blue mushrooms (such as indigo cream caps) and other species that turn blue when disturbed.
