What you should know about food.
In addition to choosing beans with low caffeine content, such as Arabica beans, current food processing technologies can significantly reduce the caffeine content of coffee in three main ways: solvent washing, Swiss water washing and supercritical extraction.
Coffee is currently one of the most popular drinks, drinking in a variety of ways, latte, American, espresso and so on. The most well-known ingredient in coffee is caffeine (caffeine). Caffeine is an alkaloid that competes with adenosine for its receptor in the brain, thus preventing us from activating the sleep mechanism and giving coffee a "refreshing" effect.
Because of their genes, some people are particularly sensitive to caffeine. As long as they consume a certain amount of caffeine, they will have side effects such as insomnia, headaches and elevated blood pressure. So these people are not sensitive to caffeine-related products. But can coffee not have caffeine?
In addition to choosing beans with low caffeine content, such as Arabica beans, current food processing technologies have been able to significantly reduce the caffeine content of coffee in three main ways:
1. Solvent washing: caffeine can be dissolved and removed by using organic solvents, such as ethyl acetate, washed coffee beans or coffee powder.
2. Swiss washing method: soak the coffee beans in warm water, caffeine will gradually dissolve into the water, and then use activated carbon to absorb caffeine to remove caffeine.
3. Supercritical extraction: in high pressure and low temperature environment, carbon dioxide will form liquid, and then liquid carbon dioxide will wash coffee beans, caffeine can be dissolved and removed.
However, solvents, water and carbon dioxide are not caffeine specific, so other nutrients and aroma substances will be lost during washing, and these caffeine removal methods can not completely remove caffeine, so the products on the market are called "decaffeinated coffee", and the label claims to be low caffeine coffee with a concentration of less than 20 ppm, which translates to about 4 milligrams of American coffee. Far lower than regular coffee, it is another choice for caffeine-sensitive people.
