Caffeine is a natural element of coffee. Therefore, the method of decaffeination is often considered as unnatural. Coffee lovers may enjoy it with little bit of caffeine in it too. However, it may wreak havoc to the caffeine sensitive person. By selecting from unblended, blended and flavorful coffee, variations are even found with the decaf coffee also. Through European method and chemical free method, you may able to know about how to make decaf coffee easily.
Prior to the World War 1, decaf coffee has been introduced in United States of America. Development in the coffee industry has been noticed as they manage to produce coffee without caffeine. However, flavor of the coffee is not lost certainly in the process. High quality of brew is maintained throughout the process.
In water, coffee is soluble at 175°. However, the method is not obtained for decaffeination as they may take away all the flavors in addition to aroma. Presence of an agent has been observed with the method naturally. To retain the flavor of coffee, it is important to select the agent carefully.
So, How to make decaf coffee? Both chemical free process with carbon dioxide and European Decaf or methylene chloride are often included as an agent for decaffeination. Bubbles are generally developed through carbon dioxide within a beverage. However, methylene chloride is a light chemical of organic nature. Further details can be found on the subject in this article.
Decaffeination with Chemical Free Method
Difference is observed with the decaffeination method through carbon dioxide. In the natural form, carbon dioxide remains as a gas. In high pressure, it is generally turns to liquid. Benefit of this feature is taken during decaf process. Flavors of the coffee may not touched at all.
Through the steam, green beans of coffee are softened first. Later on, coffee beans can be infused within the carbon dioxide. Use of carbon dioxide in liquid form is basically noticed on the occasion. Due to high amount of pressure, it becomes easy to eliminate caffeine from the coffee beans. Later on, CO2 is also drawn out. Therefore, you may get a coffee from which 97% of caffeine has been extracted. Residue of the remaining solvent may be dissipated with time as it is placed within normal pressure. This kind of decaf coffee is presented with the tag of café fair in most occasions.
Decaffeination with European Method
How to make decaf coffee? It is a kind of question that may revolve around your head while taking a sip from the cup quite naturally. In European decaf method, methylene chloride is used. It is also a liquid. However, it may not be retained in high pressure to maintain the liquid form. Following to a dip of coffee beans in a solvent, it is drained. Evaporation techniques are also applied to get rid of residual solvent. Soaking of about eight to twelve hours is necessary at the time. Finally, moisture is removed from the coffee bean through vacuum drying method. It is not possible to locate any part of solvent after the coffee beans are roasted.
