- Pentadin
Pentadin, a sweet-tasting protein, has been was discovered and isolated in 1989, in the fruit of
Oubli ("Pentadiplandra brazzeana Baillon"), a climbing shrub growing in some tropical countries ofAfrica .

Isolation and characterisation of Pentadin, the sweet principle of Pentadiplandra-Brazzeana Baillon.

The berries of the plant were incredibly sweet African locals call them "j'oublie" (french for "I forget") because their taste helps nursing infants forget their mothers' milk.

It is reported to be 500 times sweeter than
sucrose on a weight basis. With its sweetness having a slow onset and decline similar tomonellin andthaumatin . However, pentadin sweet profile is closer to monellin than to thaumatin.
