1938, Nestle Switzerland developed an instant coffee called "Nestle Coffee", which was once a necessary drink for the US military during World War II.
However, instant coffee was not invented by Nestle. The patent of instant coffee was originally obtained by Japanese Satoshi Kato (1901April17), who submitted a patent application to the United States. In the application, the existing problems and solutions of coffee preservation are expounded in detail. 1903, 1 1 In August, Kato obtained the "Patent No.735777" of "Coffee Concentrate and its Preparation Process". It's just that this patent didn't make him make a lot of money. . . . . hahaha
It was not until 1909 that another inventor, George C. L. Washington, began to mass-produce "Red E Coffee". Soon after, the first world war broke out, and providing timely coffee for American soldiers on the European battlefield was a major event that the US Department of Defense needed to consider at that time. Instant coffee is becoming popular! But at that time, the technology was backward and could not be preserved, so there was no fire. . . . .
