A French press-like quality high volume, electrical, automatic beverage brewer (10) with a rotatable mixing chamber (12) for mixing water (109) from a hot water tank (28) with dry beverage ingredient (108) having a closed top (7) and an open bottom (3, 66) to which is releasably mounted a brew basket (14) with an open top (19) for fluid communication with the mixing chamber (12) through the open bottom (3, 66). Before mounting, the brew basket (14) is loaded with a filter (105) and dry beverage ingredient (109). The mixing chamber (12) with the brew basket (14) attached is then automatically turned upside down (FIG. 6) to dump the dry beverage ingredient (109) out of the filter (105) and onto the closed top (7) of the rotatable mixing chamber (12). A preselected amount of water (109) is then infused into the mixing chamber (12) to a level beneath the open bottom (3) and filter (105) and onto the dry beverage ingredient (109) for mixing therewith. After a preselected mixing time period is passed the mixing chamber (12) and mounted brew basket (14) is automatically turned right side up to pass the beverage (110) through the filter (105) and out of the drain hole (90) of the brew basket (14). After the mixing chamber (12) has been returned to an upright position, pressurized air (44,46,48) is automatically injected into the mixing chamber (12) to hasten the passage of beverage (110) through the filter (105) and out of the drain hole (90).

The present invention provides a method for obtaining a chlorogenic acid composition which contains high concentration of chlorogenic acids and a reduced amount of caffeine at a high yield.

A method of producing a chlorogenic acid composition, which comprises allowing a water-soluble composition extracted from raw coffee beans or roasted coffee beans to be adsorbed to a column filled with an adsorbent and then eluting a chlorogenic acid composition by passing a 0.5 to 20 vol % ethanol aqueous solution.

The invention relates to a method for making a coffee composition, the method comprising separating coffee beans from the pulp and husk of a coffee cherry, roasting the coffee beans, and adding dried pulp and/or husk of the coffee cherry to the roasted coffee beans. The invention also relates to a coffee composition comprising roasted coffee beans and pulp of a coffee cherry and/or husk of a coffee cherry. The invention further relates to a coffee beverage comprising a coffee composition of the invention, and to the use of pulp and/or husk of a coffee cherry to modify the taste of a coffee composition made of coffee beans.

The present invention provides a method for stabilising the aroma of aroma-rich foodstuffs and their products by reducing the amount of phenols derived from decomposition of polyphenols contained therein. The invention also describes aroma-stabilized foodstuffs as well as their products having a desirable flavour.

A process for stabilizing a coffee aroma-providing component such as coffee aroma against loss or degradation of its flavor or sensory characteristics by associating the coffee aroma-providing component with a stabilizing agent in an amount effective to reduce or prevent the loss or degradation of the flavor or sensory characteristics of the component and form a stabilized coffee aroma-providing component followed by removing the stabilizing agent from the stabilized coffee aroma prior to packaging for storage or prior to adding the stabilized coffee aroma to a food or beverage product. The resulting stabilized coffee aroma-providing component is essentially free of the stabilizing agent and may be incorporated into a food or beverage product with the initial flavor or sensory characteristics of the stabilized component being retained for a time period of at least two months during storage of the food or beverage product.

The invention relates to a process for improving the flavour of roasted Robusta and Arabica quality coffee and is characterised by modifying roasted coffee flavour precursors in aqueous extracts of green coffee beans.

Disclosed is a container-packed milk coffee beverage which has an excellent hypertension ameliorating effect and can be ingested in an ordinary manner. A container-packed milk coffee which has a pH falling within the range from 5 to 7 and satisfies the following requirements (A) to (C): (A) a chlorogenic acid: 0.01 to 1% by mass; (B) hydroxyhydroquinone: 0.08% by mass or less relative to the mass of the chlorogenic acid; and (C) the chlorogenic acid/a coffee solid content ≧0.03 (by mass).

Provided is a coffee composition having an excellent hypotensive effect. The coffee composition has the following components (A) and (B): 0.01 to 1% by weight of chlorogenic acids (A), less than 0.1% by weight, based on the weight of the chlorogenic acids, of (B) hydroxyhydroquinone.

A filter for fluids includes a pair of layers or multiple layers or pairs of material joined together to form a laminate having a fluid contacting surface. A plurality of spaced pockets is formed between the layers of material in the contacting surface. The layers of material are fluid permeable at the pockets whereby fluid may flow through the laminate at the pockets. The fluid contacting surface is fluid impermeable except for the pockets to require the fluid passing through the laminate to be confined to flowing through the pockets. Filter members are in the pockets for removing any contaminants from the fluid. Alternatively, additive materials such as powdered cream or sugar in the pockets dissolve in the fluid passing through the pockets to enhance the fluid.

The present invention relates to a method for production of a chlorogenic acid-containing material, including the method of contacting a coffee bean extract (A) with a mixture of a water-miscible organic solvent (B) and water (C) under such conditions that the weight ratio between the components (B) and (C) obtained after the mixture is mixed with the component (A) becomes 70/30 to 99.5/0.5; and recovering a solid portion.

According to the present invention, a chlorogenic acid-containing material having a less disagreeable taste and less unpleasant odor can be obtained by a simple and convenient method.

A beverage formulation comprising a beverage having caffeine wherein the beverage contains caffeine levels in the range of about 0.07 to about 0.30 mg/ml, being optically clear, and having an added aroma; and wherein the beverage comprises an extract that is derived from at least one member of the group consisting of coffee cherry husks and coffee cherry pulp; wherein the extract is in the range of about 5 to about 30% based on standardized extract of the beverage; wherein at least a portion of the caffeine is derived from the extract; wherein the optically clear is measured by a haze value of at least below about 10; and wherein at least a portion of the added aroma is derived from aroma recovered from the extract.

The invention also provides a process for producing refined roasted coffee beans, which includes contacting raw material roasted coffee beans having a Hunter L value of 12 to 35, with coffee bean-derived extract-containing water selected from water containing an extract derived from roasted coffee beans having a Hunter L value of 40 or more and water containing an extract derived from raw coffee beans.

The present invention belongs to the field of mechanics and refers to a device for selective processing of mixtures of green and ripe coffee cherries. Said device is a helical conic apron comprising vibro-elastic inserts which pliability allow them displace proportionally to the size and hardness of different coffee cherries. Additionally, the present invention refers to an integral machine comprising helical conic aprons with vibro-elastic inserts, which does not use water and is designed to receive mixtures of ripe and green coffee cherries, depulp ripe cherries, separate semi-pulped green cherries by a separating machine and remove the pulp from ripe cherries. Finally, the present invention refers to a method for the selective processing of mixtures of green and ripe coffee cherries by the use of the already mentioned integral machine.

The present invention provides a method for producing roasted coffee beans useful as a starting material for a coffee beverage having rich body, suppressed in unpleasant taste and reduced in the amount of hydroxyhydroquinone. The method for producing roasted coffee beans of the present invention includes placing starting material roasted coffee beans in an airtight container and subjecting the roasted coffee beans to a heat treatment at from 100 to 160° C. under humidified conditions.
