Toothpaste doesn’t sound like the most palatable thing in the world, but some people have taken it upon themselves to come up with the right formulation to make it edible. It’s called Neonisin and it’s going to be available in Japan this summer.
The active ingredient in the edible toothpaste is Nisin, which is a peptide that’s harvested from lactic bacteria. This is often found in soy bean curd. Natural flavoring, plum extract, mint oil, and corn-based thickeners are then added into the mix to create the toothpaste. In some ways, I guess you could say that Neonisin is basically just a tofu toothpaste – or Tofupaste for short.
When released, Neonisin toothpaste will be cost about $8.90(USD) for a 2.5 ounce tube.
