Shown is a method of making a coffee concentrate, and a coffee concentrate obtainable by the method. The method involves primary and secondary extraction, with split tapping of the primary extract into a first and second primary draw off. The extraction is conducted under such conditions as to satisfy a minimum mass transfer Fourier number, and a minimum ratio of the extraction yield of the first primary draw-off to the extraction yield obtained in all extraction sections.

Provided herein is a method for extraction of crude coffee oil (CCO) from spent coffee ground (SCG) using Mechanical Hydraulic Press Machine. The extraction includes a preliminary step of reducing moisture content of the raw material followed by mechanical extraction of the spent coffee ground to obtain crude coffee oil. Also provided herein is a chemical-free method for purification of crude coffee oil to obtain pure coffee oil.

The present invention is directed to a technique of producing an ultra-concentrated liquid coffee that is shelf-stable at ambient temperature without the need for refrigeration or freezing. This invention further relates to a process for manufacturing ultra-concentrated stabilized liquid coffee with enhanced freshness, aroma and flavor retention without acidity or bitterness.

The present invention relates to a composition of a ready to mix drink with green coffee extract as the main component. The current embodiment of our present invention includes three types of composition to provide flavour difference. Namely, mocha coffee, roasted coffee and cappuccino coffee flavour. The main components of the composition include the following ingredients in all the variants namely green coffee extract (50%), pullulan, propylene glycol, maltodextrin, polyethylene oxide, glycerol, polysorbate 80, sorbitol, nuesilin UFL2. Di basic calcium phosphate anhydrous, with only the flavoring agent as the changeable component to the composition.
