Namely dissolve coffee and is actually invented by Japanese, there is a chemist Mr. Kato at the beginning of the 20th century, have invented and dissolved coffee promptly with the name of So-luble Coffee. Namely it is to start to dissolve quantity production of coffee after the thirties, when one company of Switzerland joined and developed the competition, in U.S.A. one company, develop one with coffee absolutely as dissolving coffee promptly of raw materials, and because of this welcome, then [Instant Coffee ] name fix formally from then on.

即溶咖啡其實是日本人所發明,二十世紀初有位化學家加藤先生,以So-luble Coffee的名稱發明了即溶咖啡。即溶咖啡大量生產是始於三十年代以後,瑞士某公司加入開發競爭時,在美國的一家公司,便開發出一種以百分之百咖啡為原料的即溶咖啡,並且因此而大受歡迎,於是〔Instant Coffee〕名稱從此正式定下。
  即溶咖啡分成二種製法,一是噴霧乾燥法,一是凍結乾燥法。
