Abstract
The present disclosure relates to methods and/or techniques for the production of cold-brew coffee extracts, which enable continuous and rapid extraction and simultaneously improved yield of aromatic constituents and nutritionally beneficial components (e.g., polyphenols, antioxidants, and/or sugars) when compared to known cold-brew techniques. The method enables continuous processing within a shortened time frame, while producing extracts with improved flavour yield, intensity and body. In addition, cold-brew coffee extracts and instant powders prepared by said methods are described.
Claims19
A method for producing a cold-brew coffee extract, the method comprising the steps of:
- (1) adding water to coffee beans to form a suspension;
- (2) wet grinding the suspension in multiple steps to provide a suspension having an average particle size less than or equal to 100 μm;
- (3) subjecting the suspension of step (2) to one or more separation steps, wherein the suspension of step (2) is separated into at least one liquid phase and a solid phase, the at least one liquid phase comprising coffee aroma, and the solid phase comprising wet coffee grounds;
- and
- (4) further processing at least one liquid phase to provide the cold-brew coffee extract, wherein the temperature of the suspension during steps (1) to (3) does not exceed 47° C.;
- and wherein the cold-brew coffee extract obtained in step (4) exhibits a residual fat content of 1 wt % to 10 wt % and a dry matter content of 2 wt % to 12 wt %.
