406：Production of instant coffee

Up until extraction, the process of producing instant coffee is the same as the process used to produce regular coffee. Thereafter, concentrating and drying the coffee produces instant coffee.
There are three main methods of production: (1) Spray-drying at high temperature. (2) Freeze-drying at low temperature. (3) Agglomeration (this method involves adding moisture to instant coffee produced by means of the spray-drying method).
