 10 Coffee Bean Processing Decaffeination The term  decaffeinated coffee  may strike some as an oxymoron, but a number of coffee drinkers relish the taste of coffee but cannot tolerate the jolt from caffeine. The main methods of decaffeination are based on chemical solvents, carbon filtering, carbon dioxide extraction, or triglycerides. In all cases, to make “decaf,” the caffeine is removed in the green bean stage, before the coffee is roasted. The process of decaffeination was initially solvent-based (in the early 20th century using benzene but later using methylene chloride or ethyl acetate). In the direct method, the coffee beans are steamed and then rinsed by the chemical agent. In the indirect method, the chemical agent never touches the beans but treats the water-base coffee solution in which the beans are first soaked. Although some high-volume companies still decaffeinate by using solvents (mainly et...

9 Health Effects   A 2017 review of clinical trials  found that drinking coffee is generally safe within usual levels of intake and is more likely to improve health outcomes than to cause harm at doses of 3 or 4 cups of coffee daily. Exceptions include possible increased risk in women having bone fractures, and a possible increased risk in pregnant women of fetal loss or decreased birth weight. Results were complicated by poor study quality, and differences in age, gender, health status, and serving size. Digestion A 1999 review found that coffee does not cause indigestion, but may promote  gastrointestinal reflux . Two reviews of clinical studies on people recovering from abdominal, colorectal, and gynecological surgery found that coffee consumption was safe and effective for enhancing postoperative gastrointestinal function. Mortality In 2012, the National Institutes of Health–AARP Diet and Healt...
