Coffee extraction occurs when hot water is poured over coffee grounds, causing desirable compounds such as caffeine, carbohydrates, lipids, melanoidins and acids to be extracted from the grounds. The degree to which extraction occurs depends on a number of factors, such as water temperature, brewing time, grind fineness, and quantity of grounds.
The caffeine in coffee boosts metabolic rate, increasing how quickly your body burns fat, studies have found. Another smaller study found that ingesting caffeine led to a 13% increase in calorie ...

This process is identical to one of the techniques for making decaffeinated coffee. In supercritical fluid extraction, high pressure carbon dioxide gas (up to 100 atm.) is used as a solvent. Due to the low heat of process and the relatively unreactive solvent used in the extraction, the fragrant compounds derived often closely resemble the ...
The compound is obtained from cinchona bark, coffee beans, and the bark of Eucalyptus globulus. [2] It is a constituent of the tara tannins. Urtica dioica, the European stinging nettle, is another common source. [citation needed] It is made synthetically by hydrolysis of chlorogenic acid. Quinic acid is also implicated in the perceived acidity ...
A new study has found that consuming 6 milligrams of the coffee compound cafestol twice daily for 12 weeks might help reduce weight and body fat but not improve insulin sensitivity or glucose ...
