The present invention provides a process for producing a powdered drink
characterized by subjecting a liquid food to electrolysis treatment
and/or current passage treatment, and drying and powdering, further
allowed by granulating, if necessary. As the liquid food, coffee extract,
coffee essence (concentrated coffee extract), milk, pretreated milk and
etc. may be used. The instant coffee obtained in the invention can be
preserved for a long period of time without deterioration of flavor or
quality, without using a food additive.
