The origin and development of decaf: why are all Swiss decaf sold?

Starbucks has two ways to remove caffeine:

1. Direct contact method:

First, the green beans are softened in warm water, and then a chemical [methanol chloride] is added.

The melting point of this chemical is so low that it will be completely destroyed at 40 degrees. Coffee is usually brewed at a temperature of 93 degrees, so Starbucks' decaffeinated beans don't contain methanol chloride. !

After adding, release the caffeine from the coffee beans. This method can effectively preserve the flavor of coffee beans, and the released caffeine can also be resold to drugmakers to make painkillers or beverage manufacturers to make caffeinated beverages! Starbucks sells low-coffee beans that are 99% decaffeinated.

two。 Swiss washing method:

This way is to soak the green beans in warm water and dilute the caffeine from the beans into the water. When the water is separated from the coffee beans, the flavor and caffeine of the beans only run into the water. This kind of water is called flavored water, and then the flavored water is filtered out of the water with activated carbon. After soaking the caffeine-filtered flavored water in the beans, the coffee bean flavor in the water is introduced back into the beans to reduce the bean flavor. Ying! L lost.

The content of caffeine in coffee varies from variety to variety. In the process of baking, the more caffeine is baked, the lower the caffeine content. But here's the problem.

Decaffeinated or even decaffeinated coffee is generally on the market, but if you treat it in this way, you will get coffee with only coke or ashtray flavor.

So decaffeinated coffee or decaffeinated coffee is sent to the "pharmaceutical factory" to wash out caffeine after the raw beans are harvested. Don't doubt it, that's it. Because some pharmaceuticals require caffeine, pharmaceutical companies use it as a source of caffeine. !

After washing (dissolving) the caffeine from the coffee beans in a pharmaceutical factory (this is chemically, not normally washed), the caffeine in the beans is dried and roasted to become decaffeinated or decaffeinated coffee.

In fact, decaffeinated or decaffeinated coffee is mainly made for patients who cannot consume caffeine.

Some people think that drinking decaffeinated or decaffeinated coffee is healthier, so they only choose these two kinds of coffee to drink.

In fact, these two kinds of coffee are the most unhealthy, and usually after the washing process of the pharmaceutical factory, the flavor of coffee beans has been left about 60% of the untreated beans of the same variety and origin, and the flavor has been destroyed by the washing process. So in fact, natural coffee is the best!
