1903, a Japanese chemist living in Chicago, USA, obtained the world's first patent for instant coffee in the United States. In fact, the earliest appearance of instant coffee was not in America, but in 177 1 UK. However, due to the difficulty in storage, the aroma will soon deteriorate and the coffee can't be drunk, so its instant production method is only a flash in the pan in history. Until 1853, before the civil war, Americans once again challenged to make instant coffee and make powdered coffee into solid, but once again, the market was not smooth because the problem of preservation was still unresolved. Satoshi Kato, a Japanese, had studied instant green tea, so some coffee importers and seed-frying operators in the United States found him and asked him to find ways to remove water from coffee. Kato worked with some American chemists to study the specific preparation method, and then submitted a patent application to the United States at19017,65438. In the application, he elaborated on the problems and solutions of coffee preservation. In the same year, Kato Coffee Company of Kato exhibited this kind of "coffee-like" coffee in the finished product hall of American Bread Expo held in Buffalo, new york, and distributed samples for free.

Unfortunately, however, the product is not famous by Dongfeng. 1909, another inventor, George C. L. Washington, began to mass-produce "red e coffee" and provided it to American soldiers in World War I, so he obtained another patent in 1906, but it was impossible to verify whether this invention was related to Kato. 1938, Nestle Switzerland developed an instant coffee called "Nestle Coffee", which was once a necessary drink for the US military during World War II.
