Is Decaf Coffee Really Better for You?
Decaf coffee is not caffeine-free. A 2006 University of Florida report found that almost all decaf on the market retains some caffeine, and the researchers noted that five to ten cups of decaf can approach the caffeine load of one or two cups of regular coffee. For people told by a doctor to avoid caffeine because of kidney disease or anxiety, decaf is therefore not a safe substitute.
Sensitivity varies. Even moderate caffeine intake can trigger restlessness, anxiety, a rapid heartbeat, and higher blood pressure in some people, and one latte carries about 31 mg, similar to a bottle of cola. Decaf is made through several decaffeination processes, and because flavor compounds are lost along with the caffeine, the resulting cup often tastes flatter. Colombian decaf beans are widely sold, and their prices tend to sit above comparable regular Colombian lots.
Decaf coffee is often seen as a friendly alternative for people sensitive to caffeine, but is it really healthier than regular coffee? A 2006 study from the University of Florida pointed out that almost all decaf coffee still contains a certain amount of caffeine. This article will analyze caffeine residue, decaffeination processes, and health effects, while also answering the question of Colombian decaf coffee bean prices and offering purchasing ideas for coffee lovers who prefer pure flavors.
Is decaf coffee really healthier than regular coffee? A report released by the University of Florida in 2006 showed that almost all decaf coffee on the market retains some caffeine, more or less.
Caffeine is the most widely consumed drug ingredient in the world. Researchers at the University of Florida once pointed out in the Journal of Pharmaceutical Analysis that caffeine content per serving of Espresso ranges from 3 to 15.8 mg, while regular brewed coffee contains about 12 to 13.4 mg per 16 ounces. If a person drinks five to ten cups of decaf coffee in a row, their total caffeine intake is already close to the level of drinking one to two cups of regular coffee. Bruce Goldberger, another author of the journal article and a PhD at the University of Florida William R. Maples Center for Forensic Medicine, also admitted that for people advised by doctors to reduce caffeine intake because of kidney disease or anxiety, these findings may be concerning. If your doctor explicitly tells you to avoid caffeine, then you should stop drinking decaf coffee as well.
Dr. Bruce Goldberger believes that for some sensitive individuals, even moderate caffeine intake can trigger restlessness, anxiety, rapid heartbeat, and elevated blood pressure. In addition, Griffths also added a reminder that patients need to be especially careful not to drink popular coffees like Latte. Although a latte has a relatively mild coffee taste, the caffeine in one latte is equivalent to a bottle of cola, about 31 mg.
Decaffeinated Coffee (English: Decaffeinated Coffee / Decaf)
Decaf coffee beans on the market are easy to buy online, and even Starbucks sells them. But the editor does not recommend choosing decaf coffee beans, because decaf coffee loses caffeine during processing and also loses much of the flavor coffee should have. In that case, the original purpose of drinking coffee is lost.
There are mainly four ways to process decaf coffee beans:
Indirect Solvent Method
In this method, coffee beans are soaked in near-boiling water for several hours, and caffeine as well as a large amount of flavor compounds are extracted into the water. The water is then separated from the coffee beans, and methylene chloride or ethyl acetate is added. The chemical molecules break down the caffeine, which is then evaporated by heating. Finally, the liquid is reintroduced to the coffee beans so they can reabsorb the coffee oils and aroma. This method is quite popular in Europe and is also called the European method, methylene chloride method, or European process.
Direct Solvent Method
This method first steams the coffee beans for about thirty minutes so that the pores of the beans open from the heat, then adds a solvent for rinsing, usually methylene chloride or ethyl acetate. After about ten hours, the caffeine can be removed. The solvent is then poured off, and the beans are steamed again to remove residual chemicals. This method usually uses ethyl acetate and is also called the natural decaffeination method or ethyl acetate method.
Swiss Water Process
After the coffee beans are soaked in warm water, the caffeine dissolves into the water, then the caffeine is filtered out with activated carbon equipment, and the solution is poured back onto the coffee beans. This method does not use chemical solvents, but the coffee loses a great deal of flavor during filtration.
Carbon Dioxide High-Pressure Extraction Method
In this method, soaked coffee beans are placed in a stainless steel tank, and high pressure turns the released carbon dioxide into liquid, which then extracts the caffeine. Afterward, the carbon dioxide liquid returns to room temperature and turns back into gas. Due to cost reasons, this method is usually used for processing large batches of coffee beans; for example, most brand products available in supermarkets use this method.
★Just Google methylene chloride and ethyl acetate and you can see their everyday uses. Once you understand them, you will probably want to avoid decaf coffee even more.
Conclusion
If you like coffee but worry about caffeine, after reading this article you should have a more detailed understanding and will no longer want to buy decaf coffee. In fact, as long as you choose good coffee beans and pay attention to storage and brewing methods, a cup of coffee will not cause palpitations or insomnia. The caffeine in coffee is water-soluble, so drinking enough water can help your body excrete caffeine.
Caffeine is even named after coffee. If you give up the taste coffee should have just because of caffeine, that would really be a pity. The processing methods introduced in this article also tend toward chemical treatment. In this era of pursuing health, shouldn't coffee also be better the purer it is?
