If the decaf coffee brand didn’t mention the process used in decaffeination, chances are the coffee is decaffeinated using both processes: the direct- and indirect-solvent-based methods. Lastly, the beans are transferred to a separate container for roasting.Then the beans are re-steamed altogether to remove any residue of the solvent.The green coffee beans are then drained to remove the caffeine.Afterward, the beans are washed repeatedly with ethyl acetate for 10 hours until the caffeine separates from the beans.The green coffee beans are steamed to open its pores for half an hour.

Here’s how to decaf the coffee beans using the direct-solvent method: If the coffee is tagged with the phrase “decaffeinated naturally,” it means that the coffee company used ethyl acetate to extract caffeine from the coffee beans. Ethyl acetate is used in the direct-solvent process. Though direct- and Indirect-solvent-based use chemical agents to derive caffeine, they still differ in one significant way – the type of chemical agent used. So, how are these solvents used to extract and remove caffeine from the coffee beans? Below are the caffeine extraction methods using chemical agents. Still, the FDA assures you that synthetically made solutions like ethyl acetate are always safe. Between the two chemical solutions, methylene chloride is a safer choice than ethyl acetate. However, methylene chloride is a much preferred chemical agent than ethyl acetate. That’s why some roasters opt for commercially produced ethyl acetate using ethyl alcohol and acetic acid. Yet naturally obtaining ethyl acetate is impractical and costly for many coffee companies. It is naturally derived from ripened fruits, including blackberries and apples. Its level as an extraction solvent for green coffee beans does not exceed ten parts per million in soluble decaffeinated coffee extract and decaffeinated roasted coffee beans.Īnother solvent used for the direct chemical-based process is the ethyl acetate.Under certain conditions, the FDA approves its use as long as its presence in food should be: Methylene chloride and Ethyl acetate are the extracting agents used in these methods.īetween the two chemical agents, Methylene chloride is widely used to decaffeinate coffee because it doesn’t pose any health risks, according to the Food and Drug Administration (FDA). The difference between the two processes lies with the involvement of the chemical solvent with the coffee beans during the caffeine extraction process. The first and most used is the indirect-solvent process, and the second, which some people hate the most, is the direct-solvent process. Chemical-Based ProcessĬaffeine from coffee beans can be removed using the two types of Chemical-based processes. The two primary ones are Chemical-based processes and the Swiss Water Method. There are increasingly more ways to remove caffeine from coffee beans. If coffee plants have its caffeine removed, how will it be able to survive from insects? Instead, the process of removing caffeine is done before roasting the beans using the following methods. People should not be fooled with coffee labels that tell the coffee beans are naturally decaffeinated as there are no such.Ĭaffeine is essential to the coffee plant itself because it serves as a natural insecticide to the coffee plant. In this modern time, the decaf coffee is coffee beans, with 97% to 99% of caffeine content removed using methods that do not use chemicals as agents to remove caffeine. That’s because most coffee companies today decaffeinate their coffee beans with chemical-free methods. Yet if you trace back the root of all the hate, you’d realized that all issues thrown to decaf coffee are in the past. The hate over decaf is strongly felt on the internet – from quotes on Instagram with matching hashtags to memes on Facebook, Twitter, and 9GAG.
