Not Australian Sweet Lupin. Lupin has been used as a food for humans and livestock for over 2000 years, however a long “debittering” or “brining” process was necessary to remove alkaloids (bitter tasting, mild toxins) that occur in traditional (Mediterranean) as well as New World (Americas) lupin varieties. You may be familiar with Lupini Beans which are the traditional Mediterranean type.
However over the last 60 years Australian plant breeders have developed this very low-alkaloid variety, which have been selectively developed for human consumption. These varieties do not need any ‘debittering’ process and are so safe they can even be consumed raw!
