Why Brazzein
A Different Foundation for Sweetness.
Most sugar alternatives ask you to compromise—on taste, ingredients, or the experience itself.
Brazzein is a naturally sweet protein first identified in the oubli fruit of West and Central Africa. Chosen for its smooth, sugar-like taste and clean finish, it gives Kivira a better way to sweeten—without sugar, stevia, or artificial sweeteners
It is not another version of the sweeteners you already know. It is a different category entirely.
From an extraordinary fruit.
Brazzein was first identified in the fruit of Pentadiplandra brazzeana, commonly known as the oubli fruit, a climbing plant native to West and Central Africa.
Within that fruit is one of the few naturally occurring sweet proteins known to science. Its sweetness does not come from sugar. It comes from the protein’s three-dimensional structure interacting with the sweet taste receptors on the tongue.
Kivira uses pure brazzein extracted from the fruit, preserving the direct connection between this remarkable plant and the sweetness in every drop.
A DIFFERENT KIND OF SWEETENER
Why brazzein is different.
Brazzein changes the starting point. Instead of trying to make sugar, stevia, or an artificial sweetener behave differently, it creates sweetness through protein.
Protein, not sugar
Brazzein is a small sweet-tasting protein, not a carbohydrate, sugar alcohol, steviol glycoside, or artificial sweetener.
Remarkably concentrated
Depending on testing conditions, brazzein is commonly described as roughly 500 to 2,000 times sweeter than sucrose by weight.
A smoother taste profile
It is known for sweetness that feels closer to sugar, without the pronounced bitterness associated with many high-intensity alternatives.
Stable by design
Its compact protein structure gives brazzein unusual stability across heat and a broad range of acidity.
PROTEIN, NOT SUGAR
What happens after the sweet taste?
Your tongue perceives brazzein as sweet because the protein activates sweet taste receptors. After it is swallowed, the body handles it as a dietary protein, breaking it down into amino acids rather than processing it as sugar.
Because brazzein is intensely sweet, only a very small amount is needed. Its role in Kivira is sweetness—not protein supplementation—so Sweet Protein Drops are not a meaningful source of dietary protein.
This is the shift: a familiar sweet experience built on a completely different foundation.
A SWEET EOLUTIONARY TWIST
Sweet enough to fool a primate.
Brazzein activates the sweet-taste receptors of humans and many African primates, despite offering little of the energy normally associated with sugar-rich fruit.
Scientists believe this intense sweetness may help the plant attract animals that disperse its seeds. Western gorillas are a fascinating exception: changes in their sweet-taste receptor may prevent them from detecting brazzein’s sweetness—a possible evolutionary counter-move.
WHY KIVIRA CHOSE BRAZZEIN
A better answer to the usual alternatives.
Every sweetener creates sweetness differently. Brazzein gives Kivira the taste, concentration, and ingredient philosophy we were looking for in one place.
Brazzein
Protein-based sweetness, used in tiny amounts, with a smooth profile designed to feel familiar.
Sugar
The reference point for taste, but it adds sugar and calories with every spoonful.
Stevia and monk fruit
Plant-derived sweeteners from non-protein compounds, often recognized by their own distinctive aftertaste.
Artificial sweeteners and sugar alcohols
Separate categories that may bring metallic, lingering, or cooling sensations Kivira was created to move beyond.
MADE FOR REAL LIFE
The better choice is the one you want to use.
Kivira was not created to turn your routine into a science experiment. It was created to make the moments you already enjoy feel better.
Your first coffee. Your afternoon matcha. The smoothie after movement. Yogurt, tea, and the recipes where sweetness matters.
Zero sugar. Zero calories per serving. No stevia. No artificial sweeteners. No bitter finish. Just a more refined way to sweeten the day.
BRAZZEIN QUESTIONS
The science, made simple.
The essential facts behind the sweet protein powering Kivira.
What is brazzein?
Brazzein is a naturally sweet protein found in the oubli fruit, Pentadiplandra brazzeana. It produces an intense sweet taste even at very low concentrations.
Where does Kivira’s brazzein come from?
Kivira uses pure brazzein extracted directly from the oubli fruit. It is not produced through precision fermentation.
How sweet is brazzein?
Brazzein is commonly described as approximately 500 to 2,000 times sweeter than sucrose by weight, depending on the concentration and testing method. That intensity is why only a very small amount is needed.
Is brazzein sugar?
No. Brazzein is a protein, not a carbohydrate sugar. Kivira Sweet Protein Drops are formulated with zero sugar and zero calories per serving.
How is brazzein digested?
After creating a sweet sensation on the tongue, brazzein is handled as a dietary protein and broken down into amino acids. The amount used for sweetness is very small, so Kivira is not a protein supplement.
Is brazzein the same as stevia or monk fruit?
No. Stevia and monk fruit create sweetness through plant-derived non-protein compounds. Brazzein creates sweetness through a protein with a completely different structure.
Does brazzein have a bitter aftertaste?
Brazzein is known for a smoother, more sugar-like taste profile than many high-intensity sweeteners. Kivira’s formula was built specifically to deliver clean sweetness without a bitter finish.
Can brazzein be used in hot drinks and food?
Yes. Brazzein is unusually stable across heat and a broad pH range. Kivira Sweet Protein Drops are designed for coffee, tea, matcha, smoothies, yogurt, and select food applications.
