What about the selection process and price of decaf?

Coffee is a drink made from coffee beans into powder and brewed with hot water. It tastes bitter, but it has a special aroma. It is one of the main drinks for westerners. It originated in tropical Africa, and now it is also cultivated in Yunnan, Guangdong and other provinces of China. Its seeds are called "coffee beans". Fried flour can be used as a drink, that is, coffee.

Selection process of low-sugar coffee

At present, the way to remove caffeine is the Swiss water treatment of raw beans-soaking-flavor water (filter of activated carbon)-through simple diffusion-repeated-rinsing-drying (baking).

Selection price of low-sugar coffee

This method is complex and expensive. After the coffee is dried, the water containing the flavor of the coffee is evaporated and concentrated, and finally sprayed back to the dried coffee beans. The real decaffeinated process is expensive, and raw coffee is shipped to Italy, processed to remove caffeine, and then shipped to baking centers around the world, which costs a lot of money. Therefore, decaffeinated coffee is more expensive than regular coffee.

In fact, the content of caffeine decreases gradually with the roasting process, so the caffeine content of deep-roasted beans is also lower than that of deep-roasted beans; the processing of instant coffee loses the least caffeine, and the residual caffeine content can sometimes be as high as eight times that of deep-roasted beans.
