Abstract
Monellin, an intensely sweet polypeptide, substantially free from carbohydrate, is described. Monellin is the pure proteinaceous principle of the fruit Dioscoreophyllum cumminsii, having a molecular weight of approximately 11,000, an isoelectric point of 9.3, and an ultraviolet absorption maximum (.lambda. max) of 277 nm. A process for the production of monellin is described which includes the steps of extracting the fruit with an aqueous medium, separating the extract into a carbohydrate containing fraction and a proteinaceous fraction substantially free from carbohydrate, and recovering the proteinaceous fraction substantially free from carbohydrate.
