When was decaf coffee invented

Solvent-based decaffeination utilizes Ethyl acetate found in ripening fruit and alcohol or Methylene chloride solvents applied directly or indirectly to green coffee beans to dissolve the naturally occurring caffeine. The US Food and Drug Administration has determined that neither of these solvents poses a health risk, but some coffee connoisseurs find that coffee decaffeinated with a solvent-based method has less flavor and depth than coffee decaffeinated by other means.

In a nutshell, the Swiss Water Process relies on caffeine solubility dissolvability and osmosis to remove caffeine from green coffee beans. To begin the decaffeination process, green coffee beans are soaked in hot water to dissolve the caffeine. Sugars and other chemical components that create the flavor and aromas of coffee we love can also dissolve in water.

So, how do you decaffeinate coffee without solvents and retain the flavor profile of your favorite beans? After soaking, the water from the first round of green beans is passed through a charcoal filter.

Caffeine is a large molecule and gets trapped in the filter while the sugars, oils, and other chemical elements in coffee that impart flavor and aroma pass through and stay in the water to create what is called Green Coffee Extract.

Go with me on a journey into memory. You are at your favorite diner, the one where the coffee is self-serve, just two old school glass carafes sitting on the same heating elements they have been for untold hours now. So there you, ready to refill your mug for the fourth or fifth time, leaving room of course for whatever amount of non-dairy creamer and sugar you need to properly gird your stomach for what the war you are about to wage against it.

You are presented with two choices: a black plastic-rimmed carafe and an orange one. Being young and invincible, you are wanting to get the caffeinated stuff. Which carafe do you choose? The answer in this walk down memory lane is simple, even if subconscious. Runge identified caffeine two years later, according to the institute. In , German coffee merchant Ludwig Roselius invented the first commercially successful decaffeination method, according to Live Science.

Some accounts claim Roselius received a shipment of coffee beans soaked in seawater , at which point he processed and tested them, determining they had been stripped of their caffeine content but tasted almost the same as regular coffee — though a bit salty. Today, there are three main decaffeination processes used to strip coffee beans of their buzz: water processing, the direct solvent method, and supercritical carbon dioxide decaffeination, according to Fergus Clydesdale , head of the Food Science Department at the University of Massachusetts at Amherst, via Scientific American.

The water processing method utilizes a mix of water and green-coffee extract and circulates it around coffee beans in an extraction battery, Clydesdale said. The direct solvent method uses methylene chloride, coffee oil or ethyl acetate to dissolve the caffeine in the beans and extract it from the coffee, according to Clydesdale. The supercritical carbon dioxide decaffeination method is similar to the direct solvent method except carbon dioxide is used as the solvent in this case, Clydesdale said.

As you think about caffeine intake, be mindful that caffeine is found not just in coffee but also in other foods and beverages, so consider all potential sources. Every body is different, so everyone should check health recommendations from recognized authorities, listen to how your body responds to caffeine, and consult your personal physician if you have any questions.
