Abstract

This invention relates to a method for removal of residual solvent from decaffeinated coffee beans. In particular, differential pressure stripping comprises a method of flash evaporation of solvent from the beans by means of an alternating cycle of pressure variations. The time and steam requirements for desolventizing are reduced when compared to traditional methods for removal of the same solvent. This reduces the residence time of the coffee beans in conditions of high temperature and high moisture, thereby preventing negative flavor changes in the resultant coffee products.
