How to reduce caffeine intake? Indonesian charcoal coffee kopi joss can effectively reduce caffeine.
Those who know decaf coffee know that decaf coffee beans are decaffeinated manually at the green bean stage. Since artificial decaffeination techniques do not remove 100% of caffeine from coffee beans, there are validation criteria for decaffeinated coffee. The European Union standard for decaf coffee is that the processed caffeine content does not exceed 0.1% of the raw beans, while the FDA standard is less than 3% of the original caffeine content.
Under the condition that the machines and conditions are developed now, there are several ways of artificial de-causation: direct/indirect solvent treatment, supercritical carbon dioxide treatment, Swiss water treatment and mountain spring water treatment. All of these are common methods of artificial cause-removal in modern times.
Back in the days of substance/technology scarcity, Indonesian people had their own way of lowering caffeine in coffee (but they didn't realize it), and only started lowering caffeine after the coffee had been brewed! This "recipe" has also been preserved and used to this day. On the streets of Indonesia, a stall owner puts red-hot charcoal into coffee, attracting passers-by's attention, while the copywriter is also attracted by "a piece of red-hot charcoal into a cup of coffee" in the video preview when browsing the video website! As you can see from the video screenshot, the stall owner first adds the brewed coffee to a cup filled with a lot of sugar, then takes out the red-hot charcoal from the nearby stove and puts it into the cup. Then use a spoon to press the charcoal to the bottom of the cup, and the coffee in the cup boils instantly.
When people taste coffee, the charcoal will remain in the cup, and after the coffee is finished, the stall owner will continue to burn the charcoal, and then continue to make the "hard core coffee".
Because red-hot charcoal put into coffee will instantly make coffee boiling effect, and produce j~o~s~~ sound, Chinese imitation sound is probably ~~~~~~~. Indonesia calls coffee Kopi, hence the name Kopi Joss.
Kopi Joss was not originally created to reduce caffeine, but Indonesian locals believe charcoal can relieve stomach discomfort and ward off cold. After adding red-hot charcoal to coffee, it is not easy to have stomach pain, and it can also digest food. It is also a good choice to drink a cup when you have a cold. Charcoal may have been added in the first place because it was thought to relieve stomach discomfort or to have a chilling effect. Last November, VOA Indonesia reported a study by Ahmad Fauzan, a chemistry student at the University of Yogyakarta in Indonesia, on the charcoal used by Kopi Joss.
According to Ahmad Fauzan's research, the charcoal used by Kopi Joss comes from tamarind trees. According to Ahmad Fauzan's research results, the charcoal after burning is very hot. Adding coffee can greatly remove caffeic acid, but it will make the brewed coffee taste better. Second, these tamarind charcoals neutralize and reduce caffeine.
"The results of the study show that charcoal is a good absorbent because it has an iodine absorption rate of 83%. Indonesian black coffee has a caffeine content of 68.78 mg/100 ml, while Kopi Joss coffee with red tamarind charcoal has a caffeine content of 55.13 mg/100 ml,"he said. The study also showed that optimal caffeine adsorption occurred at 40 minutes, with caffeine absorption of 20.15 mg/100 ml. The addition of braised charcoal had relatively no effect on the appearance and taste of Kopi joss." Despite the findings, many netizens questioned whether it was good for their health, because red-hot charcoal would shed a small amount of charcoal powder when put into coffee, and people would drink it together. Charcoal cannot be digested by the human body. If it is drunk for a long time, can it really help relieve stomach discomfort?
Every place has its own "recipe", which has been passed down from generation to generation for so many years. This is just a traditional way of making it. Try it fresh, or not drink it in large quantities for a long time. It is still OK. But if you have an upset stomach, don't drink coffee.
