Claims5
A process for preparing a dried coffee powder, the process comprising:
- (i) extracting coffee solids from roasted and ground coffee beans using water at a temperature between 30° C. and 50° C. to obtain a first coffee extract;
- (ii) filtering the first coffee extract using a selectively-permeable membrane having a molecular weight cut-off of 1 kDa to reduce a concentration of low molecular weight components, wherein low molecular weight coffee solids that pass through the selectively-permeable membrane form a permeate, and high molecular weight coffee solids that are retained by the selectively-permeable membrane form a retentate;
- and
- (iii) drying the retentate to form the dried coffee powder,
- wherein the dried coffee powder has a concentration ratio of components having a molecular weight greater than 1 kDa to components having a molecular weight less than 1 kDa of at least 5.
