Australian Magenta Ponds Are The World's Largest Beta-Carotene Farm

Beta-Carotene, as far as I’ve known since I slogged through 8th grade Biology, is a pigment that gives sweet potatoes and carrots their colour. But since it's used as a food dye and plenty of doctors recommend it as a supplement, it’s also the basis for a booming synthetic farming business in rural Australia. These photos, by Australian photographer Steve Back, give us an unusual glimpse inside the world's largest β-Carotene farm.

According to a story in Feature Shoot, Back was commissioned to shoot some conventional aerial landscapes by a luxury hotel in Perth earlier this year. Flying over the the rugged coast north of the city, the plane crossed over Hutt Lagoon, a salt lagoon separated from the ocean by a thin strip of land. Back explains:

I had noticed these lakes on the map and Google Earth, and decided that they were worth a look. From the ground, the pink colouring is not so evident and a bit unimpressive, yet from the air, it looks fantastic. These are natural landscapes but the colouring is out of this world. And at first sight it is not easy to tell whether they are close up or far away.

Hutt is home to the biggest algae farm in the world, a 418,000sqm warren of saline water and algae owned by Cognis, the massive German pharmaceutical company. There, Cognis has farmed beta-Carotene for over 30 years — it's used to colour food like margarine, but also to create the coatings on pharmaceutical drugs.

It's fascinating to catch a glimpse into such a well-established but obscure industry — and it makes me wonder what other supplement farms are out there, waiting to be discovered by the world at large, entirely on accident. Now that we've discovered beta-carotene farms, it's only a matter of time before we get an exposé on New Zealand's notorious fish oil mines.

    it almost looks coloured in with mspaint!

    Ahh, this takes me back to my Bioprocess Engineering uni labs. We grew Dunaliella salina and harvested the beta-carotene as part of a semester long practical.

    inbound just coming down the westgate bridge, look left, one pink pond there..

    Reminds me a little too much of Neon Genesis Evangelion's red oceans, stained with the blood of the Angels...

    It's owned by basf. Cognos was dissolved over 18 months ago.
