What's the difference between caffeine and decaffeinated?
The most remarkable thing about caffeine is that the taste of coffee has nothing to do with how much caffeine it contains. Caffeine itself has a slight bitter taste, and its concentration basically comes from the degree of roasting (the deeper it is, the thicker it is). The concentration of coffee is formed by the ratio of coffee to water in the process of brewing.
Bullet an average 142g cup of coffee contains 60-180mg (mg) of caffeine, depending on the concentration of coffee and the type of coffee used when mixing.
Bullet A cup of ordinary 42g (g) Espresso contains 90-120mg (mg) of caffeine. The amount of caffeine also depends on the concentration of coffee and the type of coffee used when mixing.
Bullet roasting process has little effect on caffeine. Caffeine above 77 degrees Celsius can be quickly dissolved in water, so it has been completely dissolved with coffee during brewing.
Bullet different types of coffee trees also contain different amounts of caffeine. Arabica coffee contains about 1% per cent caffeine, while robusta coffee contains about 2% per cent caffeine.
Whether caffeine has an effect on health is a topic of great concern to many people. So far, no conclusive evidence has been found that drinking coffee is harmful to human health.
Many studies have shown that coffee is actually good for the human body in many ways. For example, coffee can stimulate athletes to create better results, and the moderate stimulation caused by coffee is beneficial to many daily activities, such as relieving work stress, refreshing effect, and so on. Drinking a moderate amount of coffee will not affect human health, but it is a good drink.
All ways to remove caffeine are to increase the moisture content of green coffee beans (unroasted coffee beans), making it easy to remove caffeine. The caffeine is then extracted with a solvent, dried in the sun, and shipped to the roaster.
The solvents used to remove caffeine include water, ethyl acetate, chloromethane and carbon dioxide. These methods can be used to produce safe, good-tasting decaf coffee. The flavor of decaffeinated coffee depends on the quality of the beans, the properties of the blend, the roasting techniques and the methods used to remove caffeine.
