The history of instant coffee

In 1901, instant coffee, which can be drunk simply by adding hot water, was invented in Chicago by Satori Kato, a Japanese-American chemist. In 1906, British chemists invented the technology for mass production of instant coffee. Washington, who was living in Guatemala at the time, observed dry coffee on coffee cups. After experiments, he created "Red E Coffee" and entered the market in 1909.

In order to deal with the surplus of coffee beans, the Brazilian government and Nestle developed a more advanced spray drying method for the manufacture of instant coffee in 1938. The specific method is to use hot steam to vaporize the water in the coffee beans, leaving the dry coffee extract. Instant coffee can quickly dissolve in hot water, and it takes up less space and volume during storage and transportation, so it is more durable to store, so it is very popular in the mass market. Instant coffee was first used in the battlefield of World War II, when allied soldiers used instant coffee as a daily drink, which improved efficiency to a certain extent.
