Welcome to brain Stuff production of I Heart Radio, Hey brain Stuff, Lauren Bogel Bomb Here, red velvet cake and strawberry ice cream aren't only alike in that they'll satisfy your sweet tooth, they likely share a common ingredient made from a not so common source that gives them their red to pink Q. That's carmen, a natural red dye also labeled as Cochineal Extract E one twenty or Natural Red Dye four, and it owes its beauty to a
teeny tiny bug, the female cotton neal bug. To be precise, In addition to its possible gross out factor, this tasteless f d A approved extract has a history full of interest and intrigue. Betsy Ross even used this bright red dye to make the red stripes on the very first American flag. The cotch neal is a slate bug that feeds on prickly pear plants grown throughout Mexico, South America, the southwestern United States, and the Canary Islands off the
coast of Spain. The male cotch neil plays its own unique role in nature, but it's the wingless, legless female that interests dye makers If you go looking for her, you won't find her vibrant red bounty on display. The female cotch neil's gray exterior is covered in a white powder that protects her from predators as well as the scorching sun, and since the juice from the cacti is her only source of nutrition, she burrows in and is
understandably a bit stubborn about releasing her hold. In order to harvest the cotch neil, the prickly pear pads are cut and brought to factories so that the bugs can be pulled out and processed, but it takes some serious people power. Approximately seventy thousand cotch neals are needed to create just one pound of dye that's a little less
than half a kilo. Once the harvested bugs are dried, ground and mixed with an alcohol solution or other compounds like borax, they give way to a vibrant, long lasting dye that can be used to make colors from scarlet to purple to pink to peach. Dyes have been used to color everything from textiles to pottery since the Neolithic period or New Stone Age, but the majority sourced from vegetables, plants, and trees. But bugs have had their place too, and
not only the cocheneal. Another elusive die associated with wealth and royal status, Tyrian purple, was made from the glands of snails. The cocheneal bug is native to Mesoamerica. The Aztecs are believed to be the first to use Carmen to fill their lives with stunning shades of crimson. When the Spanish colonizers arrived in the Americas, they learned about Carmen and built enormous wealth by monopolizing the cocheneal market.
Spain kept the source of the color a secret, and even made export of the die illegal, punishable by death. Coveted by the wealthy, the royal families, and the artists across Europe, this die created fertile ground for contention. Those cumbersome and secretive production methods certainly made Carmen expensive, but the color itself was an explosive part of Carmen's mystery and popularity. We spoke with Amy Butler Greenfield, author of
The Perfect Red, via email. She said, red is the color of blood, fired, death, and desire, and we can't help but respond to it on many levels. It makes our eyes dilate and our breath come faster, and it's freighted with symbolic meaning. Also, there are very few natural dyes that make a lasting, bright, true red, so good ones had the value of rarity ounce for ounce. Coccinial is the most powerful natural red dye in the world.
That's why it was prized. When industrialization arrived in the mid eighteen hundreds, the demand for textiles increased dramatically and created a need for more cost effective dyes. Chemists began to use petroleum and coal to formulate synthetic ones, ultimately
reducing the need for the cotchinial bug. The shift towards synthetics may have pushed carmen too the background, but it didn't disappear, and now it's making a comeback, showing up on ingredient lists for anything from cake pops to lipstick. Greenfield said. When reports started linking synthetic reds to cancer and hyperactivity, and as people started taking an interest in natural foods in general, the market for cotchin neal began
to rebound. So if carmen is a natural product without the negative long term effects, why did the coffee giant Starbucks, along with numerous other companies stop using it to add color to their products. While carmen is safe for the majority of people, it can cause an allergic reaction, and besides that safety concern, folks like vegetarians, vegans, and people who keep kosher helped advocate for the change. But no matter whether you find eating a bug appalling, fascinating, or dangerous.
For such a tiny insect, the cochineal bug has certainly left a vivid mark on culture, beating our attraction to the beauty and power of red.
