A San Francisco startup has found a way to remove the caffeine from coffee using a stirring stick, according to BusinessWeek. Seven years ago, Anna Leone was on a trans-Atlantic flight when she got a caffeine craving. Not wanting to get the jitters, she ordered a cup of decaf, only to learn the plane had just run out. She opted for a cup of regular, and that’s when inspiration struck.
The subject of her reading material -those molecular polymers -can recognize certain molecules, “grab” them, and pull them out of a mixed substance. What if those very polymers, called MIPs, could pull caffeine out of regular coffee without affecting its taste or smell?
Building on her original idea, DeCaf Co has created a stirring stick that pulls caffeine molecules out of the liquid. The more you stir, the more caffeine comes out. Two stirs and you’ve effectively removed 70% of the caffeine without affecting the taste.
According to the National Coffee Association, 82% of Americans drink coffee. Decaf drinkers make up 21% of the market. Traditional methods to remove caffeine from coffee end up altering its make up.
beans are typically soaked in chemicals to dissolve the caffeine molecules. Then the beans are resoaked in decaffeinated water to reabsorb the flavor compounds, according to the Coffee Research Institute. “The chemical composition of decaffeinated coffee is altered, and therefore the flavor and aroma are changed,” according to research by the group.
In theory, DeCaf Co.’s method lets you go unleaded without giving up flavor. There’s also the convenience factor. Restaurants could toss out those ubiquitous orange-capped pots and just brew regular coffee. Need decaf? Just keep a few sticks in your purse or pocket in case a dinner party host or flight crew has only the hard stuff on hand.
Right now, the company is too small to mass market its product so it’s seeking to partner with a larger beverage company. It’s currently in the process of getting the stirring sticks approved by the FDA, so right now, there’s no word on when this may end up in stores.
