Abstract:
The invention relates to a process for the production of a liquid coffee concentrate that has an improved storage stability at ambient temperature. The process comprises treating a coffee concentrate to a heat treatment and a pH increasing step.
Abstract:
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.
Abstract:
A coffee densifier is disclosed. The coffee densifier comprises an elongated chamber, a densifier motor, a shaft, a plurality of densifier members, a discharge door actuator, a densifier motor load sensor, and a controller. The plurality of densifier members are fixed to the shaft and configured to polish a plurality of coffee particles of the ground coffee within the elongated chamber when the plurality of densifier members are rotated by the shaft through the ground coffee within the mixing chamber. The controller configured to signal the discharge door actuator to move the discharge door to increase or decrease a density of the ground coffee exiting the chamber through the discharge opening when the densifier motor load is outside a predefined densifier motor load operating range.
Abstract:
The present invention relates to the preparation of a coffee beverage powder useful for the preparation of coffee beverages such as e.g. cappuccino, café latte, café macchiato, café au lait. The method comprises the preparation of an aqueous composition comprising coffee solids and protein and/or fat, adding aroma obtained from coffee to the composition and drying the composition to produce a coffee beverage powder. The coffee beverage powder has improved aroma and/or characteristics.
Abstract:
Provided is a concentrated coffee extract solution having a rich sweet aroma and a clear aftertaste. The concentrated coffee extract solution contains the following components (A) and (B): (A) at least one pyrazine selected from 2-methylpyrazine, 2,5-dimethylpyrazine, 2,6-dimethylpyrazine, ethylpyrazine, 2-ethyl-5-methylpyrazine, 2-ethyl-6-methylpyrazine, 2-ethyl-3-methylpyrazine, 2-ethyl-3,5-dimethylpyrazine and 3,5-dimethyl-2-methylpyrazine, and (B) at least one guaiacol selected from guaiacol, 4-ethylguaiacol and 4-vinylguaiacol. A content weight ratio [(B)/(A)] of the component (B) to the component (A) is 0.6 or smaller.
Abstract:
The present disclosure relates to a process for the production of a liquid coffee concentrate that has an improved storage stability at ambient temperature. The process comprises separating coffee extract resulting in a high aromatic coffee extract and a low aromatic coffee extract and subjecting the low aromatic coffee extract to a heat treatment and, optionally, a pH rising step.
Abstract:
A coffee processor having a grinder and a densifier is disclosed. The densifier comprises an elongated housing having a mixing chamber configured to receive ground coffee. The mixing chamber has an inlet end opposite a discharge end. The discharge end has a discharge door. The densifier has a mixing shaft driven by a mixing motor, the mixing shaft extending along a longitudinal length of the mixing chamber. The densifier has a plurality of pins fixed to the mixing shaft and configured to agitate a bed of coffee within the mixing chamber. An automatic coffee density control system is also disclosed. A controller is configured to signal a discharge door actuator to move the discharge door a predefined distance to increase or decrease the mixer motor load when the mixer motor load sensor reports a mixer motor load value that is outside a predefined mixer motor load operating range or setpoint.

Abstract:
Typical known methods for producing large quantities of concentrated extracts from solid raw materials such as ground, roasted coffee are not ideally suited to producing high quality coffee extracts that are rich in flavor and fragrance, and which maintain the varietal characteristics of the roasted coffee from which they are produced. The current invention provides filtration methods for producing such high quality concentrated extracts from more dilute extracts via solvent removal. The invention provides methods that have sufficient flexibility and scalability to be used for a wide variety of applications, including for producing industrial-scale quantities of extracts for the food and beverage industry. The invention provides methods and apparatus that can produce highly concentrated, “gourmet quality” extracts for use as flavoring agents, beverage concentrates, and fragrances.
Abstract:
The invention relates to a method for preparing a coffee concentrate, wherein the coffee is subjected to two extractions, while the second extraction is carried out at a higher temperature than the first extraction. The method is suitable for preparing liquid as well as solid concentrates. The method produces a new concentrate that forms a further aspect of the present invention.
