The Method That Can Prepare Cold Coffee in 3 Minutes [Video]

A group of scientists working at the University of Duisburg-Essen in Germany has identified a very fast way to make cold coffee. Under normal conditions, it is necessary to spend a long time, such as 24 hours, to brew cold coffee, but using this method, it may be possible to brew cold coffee in a few minutes. Of course, if you have the appropriate materials and most importantly a laser. Come together; Let’s take a closer look at this development that will enchant coffee lovers.

Scientists tried to brew coffee with a technique in which they made 80,000 laser pulses per second. The experts, who continued this process for about 3 minutes, achieved very impressive results. So much so that the acidity level of quickly brewed coffee was almost the same as coffee brewed for 24 hours. The aroma level in the coffee was also acceptable. The amount of caffeine in the coffee brewed with the laser was equivalent to that of hot coffee.

Laser brewing is impressive but not usable!

While researchers have found a quick and effective method for brewing cold coffee, this method still needs to be tested chemically. It is not known whether the laser beams interact with the coffee beans. So it is not yet clear whether this coffee is healthy or not. With the work to be done, this question will also be answered and it will be understood whether the method is applicable or not.

Commenting on their research, Dr. Anna Rosa Ziefuss said this study is only the beginning. Mentioning that their aim is a laser technique that can quickly make all cold drinks, not just coffee, Ziefuss stated that if the studies yield results, they will enable this method to be used for commercial purposes. If the method is healthy and developed, it seems that these methods can be used in all the soft drinks we drink.
