Frequently asked questions
FAQ
Answers to common questions about brazzein, working with it in your formulations and requesting a sample.
What is brazzein?
Brazzein is a small, naturally occurring sweet protein first discovered in the Oubli fruit (Pentadiplandra brazzeana) of West-Central Africa. Biofect produces it through yeast-based precision fermentation as a sweetener for reduced-sugar foods and beverages.
How sweet is Biofect Brazzein?
Biofect Brazzein delivers intense sweetness at low use levels. Relative sweetness varies with concentration, the sweetness of the sugar reference and the formulation. Evaluate use levels in your own application.
Is brazzein heat and pH stable?
Brazzein offers heat and pH stability for food and beverage formulation. Performance depends on the recipe, pH, processing temperature and exposure time. Confirm sweetness and stability under your intended processing and storage conditions.
Does brazzein work with stevia and monk fruit?
Yes. Brazzein pairs well with stevia Reb M and monk fruit, helping round out the sweetness curve for a fuller, more sugar-like taste.
Does brazzein replace the bulk and texture of sugar?
No. Brazzein replaces sugar's sweetness, not its bulk. Reduced-sugar products may still need fibres, polyols or process changes to manage body, moisture and texture.

Our storyA sweetness story
A sweetness story
worth remembering.
It begins with a rare fruit so sweet it was named for forgetting, and continues with the science that brings its sweet protein to food and beverage makers.
Discovered inWest-Central Africa
The origin
Too sweet to forget.
The Oubli fruit grows on Pentadiplandra brazzeana, a climbing shrub native to the forests of West-Central Africa, and is famous for its striking sweetness. Scientists later identified brazzein as one of the sweet proteins behind it.
Its name is often linked to the French oublier, “to forget.” As local tradition tells it, the fruit was so sweet that children who tasted it forgot to go home.
