Oobli secured it's third FDA "no questions" letter, acknowledging the company assessment that brazzein-54 is Generally Recognized as Safe (GRAS) for use as a sweetener in foods and beverages, and marking another milestone in it's mission to build a commercial-scale sweet proteins technology platform for sugar reduction.
Brazzein-54, a sweet-tasting protein naturally occurring in the oubli fruit, now joins brazzein-53 and monellin on Oobli's platform. For CEO Ali Wing, the regulatory win is validation and reinforcement of a bigger strategy: to create a versatile scaleable toolkit for brands looking to cut sugar without sacrificing taste.
"What we're trying to do is really have a robust toolkit so that people trying to actually do a reformulation..will have more tools in our toolkit. I wouldn't say it changes [our regulatory strategy]. It just reinforces what our plan always was," Wing said. "Out plan always was to be a sweet protein technology platform. Across the universe of plan-based sweet proteins, there's about a dozen known in nature today, and we have our first fie with some form of regulatory platform.
Why more than one sweet protein?
One of the most common questions Wing hears is why Oobli needs multiple sweet proteins given they each bind to the same receptor to delivers sweetness. But, for Oobli diversity matters - for a sensory performance and manufacturing feasibility - as each sweet protein delivers to a different nuance of sweetness to a formula.
"There are three reasons why we really care about the platform," she explained. "Sweetener combinations often do [taste replacement] better. If goal number one is unrecognizable change, we really want to let everyone, if we blindfolded them, not know we took the sugar out. Combinations often get closer than any one individual."
Processing stability also varies within the sweet proteins given their natural sourcing.
"These plants all evolved in slightly different places on the equator," Wing said. "That means some of them have proven to be slightly different within a food manufacturing environment - some might be a little more soluble, some might be a little bit more heat stable. What we're trying to do is really have a robust toolkit...for all the different manufacturing processes that package goods eventually go through."
Nature, science and sale
Sweet proteins are derived from fruits found primarily in West Africa and other equatorial environments, Oobli Founder and CTO Jason Ryder explained.
"Sweet Proteins are a class of proteins that deliver a sugar like sweetness but don't affect blood sugar, insulin or the gut microbiome," Ryder said. "Oobli is changing the future of sweetness through the use of sweet proteins as a replacement for traditional cane sugar and other alternative sweeteners like aspartame, sucralose, stevia, and erythritol."
Building a toolkit, not just an ingredient
With brazzein-53, brazzein-54 and monellin all acknowledged by FDA, Oobli is positioning itself as a go-to platform for sweet proteins. While each mechanistically works the same way, their subtle differences open new application pathways.
"Monellin is known...to be immediately the most sugar-like. It has a slight difference," from the brazzeins, Wing said. "It's also known, compared to the brazzeins, as slightly less heat stable. Bother brazzeins are pretty well known for being a little more stable and particularly soluble," which works well in frozen applications, for example.
Oobli's platform is designed to complement - not replace - other sweetners. "We're a good kid in the playground," Wing said. "we seem to work really well with cane sugar. We seem to work really well with sugar alternatives. My goal is that we increasingly become the biggest part of the chassis of each of those sweetener systems."
From lab to market
Oobli already has commercialized its proteins in a line of dark and milk chocolates and an RTD iced tea, but the company is now expanding into larger food and beverage categories through partnerships with Ingredion, a global leader in ingredient solutions, and Mexico-based baked good company Grupo Bumbo.
"The oubli fruit sweet protein can be safely used in a wide range of foods with support from the scientific community and the FDA," Wing said. "It can replace 70% or more of sugar in products such as sodas, teas, baked goods and more, making the opportunities to reduce our sugar consumption virtually endless."
