Impossible Burgers' Key, Bloody Ingredient Wins FDA Approval (cnbc.com)

The FDA has approved the key ingredient used in the vegetarian-friendly Impossible Burger. "The ingredient, soy leghemoglobin, releases a protein called heme that gives the meat substitute its distinctive blood-like color and taste," reports CNBC. The burger comes from a company aptly named Impossible Foods, which started raising millions of dollars in 2015 to pursue a plant-based burger that truly tastes like meat. From the report: In a letter to Impossible Foods released Monday, the FDA deemed soy leghemoglobin GRAS, or generally recognized as safe, in its most recent review. "Getting a no-questions letter goes above and beyond our strict compliance to all federal food-safety regulations," Impossible Foods founder and CEO Patrick O. Brown said in a statement. "We have prioritized safety and transparency from day one, and they will always be core elements of our company culture."

    ...I can't say that I've ever missed that specific meat-like taste (even less so the color) in any of the many meat facsimiles I've tried. I suppose the reason why one becomes a vegetarian plays a big role in this.

    soy leghemoglobin, releases a protein called heme that gives the meat substitute its distinctive blood-like color and taste

    Oh my god, so much wrong with this sentence:

    • leghemoglobin is the protein
    • heme is an organic molecule
    • leghemoglobin does not RELEASE heme, it holds the molecule inside
    • when the heme molecule in the protein binds oxygen it provides the red color.

    Take a look in the mirror, and smile. The Incisors and Canines in your mouth evolved primarily for eating meat,

    Nope. Gorillas have massive canines but they never eat meat.

    Incisors? They work for plants, too. Biting apples is much easier with incisors than molars.

    The puny little canines that humans still have? Throwbacks to when we used to fight like gorillas. No use at all for hunting/killing.

    Nope. Gorillas have massive canines but they never eat meat.

    They also don't have apolipoprotein E2-E4, which developed after our common ancestors split, and is a big factor in how much meat we can eat.
