Scientists from the University of Duisberg in Essen, under Dr. Anna Rosa Zyfus, have developed a curious estimate for the extremely fast cold brewing of coffee. The classical method requires 24 hours, the experimental method will call pouring bowls of sound identity in the last The secret is that the mixture of water and coffee is treated with a laser without heating the liquid.
In one method lies the technology of laser scted production of colonides, which is involved with s s s. German chemists used laser blue waves at 532 nm, which require up to 80 pulses per second. Each pulse has a power of 125 picojoules and a duration of 10 picoseconds, so the mixture of coffee and cold water during laser irradiation heats up by several symbolic degrees.
Chemical analysis revealed the presence of food products of coffee that had been brewed for 24 hours, no new food products appeared. According to a number of indicators, laser brewed coffee is closer to coffee brewed with boiling water, or has a value in the middle between it and cold stock.
The researchers clarify that taste and aroma tests were not conducted based on the experiments, because strict regulations require a more rigorous analysis before a person consumes synthetic nutritional supplements. However, scientists are sure that the sogt adapted establishes a method for located mineral deposits from other rivers. Oh dozhen sves
