If you're reading this message, it means that you are, in some way, currently affiliated with the Coca-Cola Sweet Story Challenge. And that's awesome! What you may not have realized, however, is that this isn't the only crowdsourcing opportunity hosted by Coca-Cola on the HeroX platform. That's right - the Coca-Cola Sweetener Challenge is also open for submission.
Unlike the Sweet Story Challenge, the Sweetener Challenge is looking for you to actually help isolate and identify a compound that tastes just like sugar but is also natural, safe, and reduced/low- or no-calorie. The compound must not contain, or be derived from, Stevia or Lo Han Guo (Monk Fruit), or from any list of protected species or substances issued by any regulatory body in any country.
Sweetener is a more subject-matter-expert-specific challenge requiring a strong scientific background -- so if that sounds like you (or someone you know), give it a shot!
