Natural high-potency sweetener
Brazzein has not yet been approved as a food additive, but some food manufacturers see it as a better-tasting alternative to stevia-derived rebiana. Brazzein is a small (54 amino acids) protein molecule that occurs naturally in the berries of a climbing vine found in West Africa, where it has been consumed by people and animals. It is about 1,000 times sweeter than sugar, but, as far as we can determine, it has not been tested for safety. Because it is a protein, it might cause food allergies. One company is planning to market the sweetener under the name Cweet.
