Functional Ingredients Cheat Sheet

By Jeffrey Klineman

At this point, we’ve established a lot of what the key functional beverage trends are on the market. It’s all about general health, energy – including focus and relaxation, and all kinds of recovery (the key to emotional and psychic recovery, beer, has a widely understood functional ingredient, so we won’t address that here).

But what are the component parts of those general trends, and how do you recognize which products are best equipped to speak to those functionalities?

We checked with many of our sources at flavor and ingredient houses to try to understand just which ingredient types are in vogue when it comes to fulfilling (or trying to fulfill) a beverage’s functional promise.

Now, there’s science and then there’s science, and we can’t run tests and speak to the efficacy of these ingredients. But we can try to explore which ones are there, and why. We’d like to thank food scientist Kantha Shelke of Corvus Blue, Ewa Hudson of Euromonitor International, and all of the friendly suppliers who helped us in this putting together this, our very first functional ingredient cheat sheet.
