How Are Instant And Decaf' Coffees Made?

Instant coffee is prepared by mixing ground and roasted coffee with hot water. The water is then evaporated by spray dryers and high pressure, leaving only the coffee powder. In some coffee products, coffee is replaced with chicory, a wildflower herb; figs, dates, malt, or barley, which resemble real coffee in a small way.
To get decaffeinated coffee, caffeine is removed from by treating the green beans with chlorinated hydrocarbon solvents. Caffeine increases the power of aspirin and other painkillers, that is why it is found in some medicines.
Caffeine withdrawal is one of the most common causes of headaches. Women who drink 2 or more cups of coffee a day also have an increased risk of developing osteoporosis. This can be offset by drinking milk or yoghurt to replace the lost calcium.
Most studies have found that high caffeine consumption impairs fertility, and taken during pregnancy may cause premature or a defective birth.
