What is Brazzein?
Brazzein is a naturally occurring, high-intensity sweet protein found in the fruit of the West African plant Pentadiplandra brazzeana. It's significantly sweeter than table sugar, with estimates ranging from 500 to 2,000 times the potency. Brazzein offers sweetness without calories or affecting blood sugar. It is also known for its stability across various pH levels and high temperatures, making it useful in different food and beverage applications. Its taste is often described as clean and sugar-like, avoiding the off-tastes sometimes found in other high-intensity sweeteners.
The GRAS Process vs. FDA Approval
Understanding whether brazzein protein is FDA approved requires differentiating between GRAS status and formal FDA approval for food additives. They are distinct regulatory pathways.
What is GRAS Status?
GRAS status is determined by a manufacturer who concludes, based on scientific evidence, that an ingredient is safe for its intended use. The FDA can review this conclusion through a voluntary notification program. If the FDA has no questions about the manufacturer's safety determination, it issues a "no questions" letter. This is not an 'approval' by the FDA, but rather an acknowledgment of the manufacturer's safety conclusion.
The Path to Commercialization
For novel ingredients like brazzein, especially when produced through precision fermentation rather than direct extraction from the plant, obtaining GRAS status is a vital step for market entry. Several companies have successfully navigated this process for their specific brazzein products.
Brazzein Production and Regulation
Commercial brazzein is typically produced through precision fermentation, a biotechnological process that uses microorganisms to generate the protein. This method offers benefits over traditional farming including sustainability, purity, and scalability. Multiple companies, including Oobli and Bestzyme, have received FDA "no questions" letters for their specific brazzein products, acknowledging their GRAS status. Sweegen's brazzein technology has also achieved FEMA GRAS status for use as a flavor.
Brazzein vs. Other Sweeteners: A Comparison
Brazzein offers zero calories and a clean taste, differing from sweeteners like stevia or monk fruit which can have aftertastes. It is also highly heat stable, suitable for various food applications. Like many alternatives, it has zero glycemic impact, making it suitable for diabetics, and is considered gut-friendly.
Benefits and Potential Applications
Brazzein's stability and taste make it suitable for various food and beverage applications, including drinks, baked goods, and dairy. Its benefits include zero calories and low glycemic impact.
Conclusion
While brazzein protein is not formally FDA approved as a food additive, specific formulations have received FDA "no questions" letters regarding their Generally Recognized As Safe (GRAS) status, such as those from Oobli and Bestzyme. This regulatory acknowledgment, combined with its properties, positions brazzein as a promising sugar alternative.
