How Do They Decaffeinate Organic Coffee?
Organic products and foods can help anyone lead a healthier lifestyle, so the purchasing decisions we make when it comes to coffee are often made mindfully and sustainably. What happens before our morning cup hits our cup can have serious ramifications on both our environment and health.
Water Process
Decaffeinating coffee entails extracting caffeine molecules while leaving other key flavor compounds intact in the beans, creating an organic product with minimal chemical impact on health or taste. Early pioneers of decaffeination processes sought ways to avoid using chemicals which might compromise both. Subtle Earth Organic employs a process known as diffusion which uses only water as its solvent to gently separate caffeine from beans by diffusion; similar to osmosis but with different goals: moving caffeine molecules from bean into water where they dissolve more readily than otherwise.
By employing this chemical-free process, small batches of green coffee beans are immersed in water containing flavor but no caffeine, known as Green Coffee Extract (GCE). They’re left to soak at a consistent temperature for around 10 hours – enough for any soluble caffeine molecules to move out of their beans into GCE water via osmosis and dissolve there before draining and being reused to extract additional amounts from fresh batches – without leaving behind any chemical residue behind.
Jim’s Organic Coffee utilizes this environmentally-friendly method for decaffeination that preserves both natural flavors of beans as well as their unique characteristics – something similar to roasting at low temperatures to preserve aroma and flavor. They use this 100% water-based process exclusively when decaffeinating their organic coffees to ensure an exceptional cup of java. In addition to being eco-friendly, it allows Jim’s Organic Coffee’s unique organic beans’ distinctive tastes and characteristics to come through for maximum enjoyment of every cup!
Other chemical solvents are available for decaffeinating coffee, but these come with significant drawbacks. Some have been linked to health issues like cancer and others can leave behind an unpleasant or bitter flavor in your coffee. Methylene chloride process was once the go-to way to decaffeinate coffee; it is harmful both environmentally and can still contain trace amounts after decaf is complete; other solvents like ethyl acetate are natural and safer alternatives, though they still leave an undesirable flavor behind that some find unappetizing taste;
Methylene Chloride Process
Methylene chloride is used as an organic solvent decaffeination process to dissolve caffeine from green coffee beans, known as organic solvent decaffeination and popular since the early 1900s. Unfortunately, due to health concerns and environmental considerations surrounding its production, consumers do not always prefer this decaffeination method; although FDA and Occupational Safety and Health Administration have determined that low concentrations pose only minimal risks to human health methylene chloride should still be avoided when possible.
Decaffeination starts by steaming and soaking green coffee beans in water to increase their moisture content from 10 to 25 or 40 weight percentage. This enables methylene chloride to more readily penetrate bean matrix and extract caffeine molecules more effectively, before returning beans back to original moisture level with stream of methylene chloride removed and leaving behind only flavor compounds from essential oils present within beans and no residual methylene chloride left in final product – much better for our environment!
This energy-efficient decaffeination process uses water as its main byproduct, which is then filtered and reused later. Beans are then transferred to a water tank where pressurized carbon dioxide gas can remove caffeine by having molecular structures similar to coffee beans, making it easier for it to dissolve than large, polar molecules like carbohydrates or proteins.
At this stage, coffee is also dehydrated to remove any chemical solvent residue in its final product. Water-based decaffeination methods are environmentally-friendly and do not create any ozone issues; however, some chemical residue (10 ppm max) remains after decaffeination has taken place; though many consumers would rather avoid this scenario.
Consumers looking to reduce the level of chemicals in their morning cup of joe should look for labels that indicate which method was used for decaffeination. While not required by FDA regulation, companies often list “solvent-free,” “chemical-free,” or the Swiss Water Process on their packaging. As an alternative option, consumers may look for organic certification that prohibits synthetic pesticides, fertilizers, and chemical solvents as decaffeination methods.
Ethyl Acetate Process
Ethyl Acetate (CH3CO2C2H5), unlike Methylene Chloride decaffeination methods, occurs naturally in fruits like bananas and oranges; commercial production takes place via ethanol-acetic acid reaction or petroleum distillates. Either way, its molecular makeup makes it an excellent solvent for coffee beans as it bonds to and dissolves caffeine molecules; once steamed beans have been immersed into an Ethyl Acetate solution they are then rinsed multiple times to pull away caffeine before being steamed again to remove any remaining Ethyl Acetate; typically this process decaffeinates 97% of their caffeine content
Steaming green coffee seeds until they swell opens their pores to make them more susceptible to decaffeinating agents, like ethyl acetate. Steamed seeds are then placed in a tank filled with both water and ethyl acetate which binds with caffeine molecules before being rinsed several times; after each rinse cycle the excess ethyl acetate drains away while washed steamed beans are repeated; until caffeine levels in beans have been significantly reduced.
Ethyl Acetate is considered more “natural” than other chemicals like Methylene Chloride and is therefore sometimes used for coffee decaffeination. Additionally, its environmental friendliness makes it desirable; however it may be impractical or expensive to obtain directly from fruit; so factories produce it by synthesizing ethyl alcohol with acetic acid instead, producing similar results to Methylene Chloride without its negative side effects.
Due to environmental and health benefits, some roasters use an Ethyl Acetate process when roasting organic and specialty coffees. It should be noted that even though Ethyl Acetate leaves behind trace amounts of chemicals in its beans, Jim’s Organic Coffee prefers using Swiss Water Process instead for their decaffeinated options.
Other Processes
As organic coffee becomes more in demand, so too do concerns over its environmental impacts. Coffee production takes a significant toll on local ecosystems and communities worldwide. Many farmers have responded to these worries by cultivating their crops under shade trees; this helps preserve rainforest health while keeping coffee beans cool and protected from sunlight to preserve flavor in each bean.
While the direct solvent method may be the fastest and easiest way to extract caffeine from green coffee beans, it also leaves behind residual chemical compounds that leave an aftertaste that is distinctive from that produced using another process such as water filtration or cold extraction. Chemical residues become especially apparent with decaf coffees produced using chemicals such as methylene chloride or ethyl acetate which leave their own distinct undertones behind in the final brew.
Decaffeination pioneers have sought out more natural and organic methods of decaffeinating coffee, such as The Swiss Water Decaffeination Process. This technique uses only water to extract caffeine from green beans soaking them under high-pressure carbon dioxide to remove both caffeine and non-water-soluble constituents, without altering their flavor profile.
Resteaming and soaking beans in their original water allows us to regain flavor compounds and oils lost to prior liquid treatments, and leave behind beans as flavor-filled and natural as possible. The process may need to be repeated multiple times until all caffeine has been removed – leaving behind only flavor-filled and natural beans!
Organic decaffeination processes used for our organic decaf coffee provide a healthier alternative than conventional methods. The Swiss Water process offers an extremely effective and efficient means of removing caffeine while still retaining their natural flavors and aroma, so every cup is free from potentially hazardous chemicals.
