The natural blue pigment INDIGOIDINE.

Color blue evokes interest. Blue is one of the rarest colors among all the natural pigments (chemicals that preferentially absorb and reflect particular visible light wavelengths). In the past, making blue dye was such an expensive endeavor that medieval Europeans valued it on par with gold. Because blue is a symbol of riches and rank, artists only used it on the most significant occasions. So dive into my list and read all about this natural pigment indigoidine, its characteristics and applications and more.

The blue color of the indigoidine compound is bright and sustainable. As a natural dye, it has promising health benefits as an antioxidant and antimicrobial actor. Because of a new purification process patented with the compound, indigoidine natural blue dye is safe to use in food and drinks.

The blue pigment indigoidine has grabbed the attention of many as a natural dye. Pictured above is one of the various bacteria that produce this rare natural blue pigment, corynebacterium insidiosum. Other bacteria that produce this pigment include: corynebacterium glutamicum, roseobacter Phaeobacter sp. strain Y4I, S. cerevisiae and some more.
