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 e.g. reverse osmosis or nanofiltration 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. The solvent—reduced, concentrated extracts produced according to the inventive solvent removal methods can be advantageously used for applications where high quality coffee extracts, with a high concentration of soluble coffee solids, for example of at least 6 wt. %-40 wt. %, and a high level of retention of varietal flavor and fragrance characteristics are desired.

Typical current methods for producing large quantities of extracts from solid raw materials such as ground, roasted coffee are designed for exhaustive extraction. Such methods 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 methods and apparatus for producing such high quality extracts. 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. The inventive extraction methods, in some embodiments, involve subjecting roasted coffee to a static pressure treatment with pressurized solvent and / or removing extract from the bed of roasted coffee with a non-solvent gas as a final extraction step. The inventive methods can reduce the extent of extraction of the roasted coffee and the level of bitter, off-flavor components present in the coffee extracts. The extracts produced according to the invention can be advantageously used for applications where high quality coffee extracts, with a relatively high concentration of soluble coffee solids and a relatively high level of sweetness but without substantial amounts of bitter oils and acids, are desired.

A brewable coffee product usable to produce a coffee beverage. A first version coffee product includes ground roasted coffee, cocoa, a vanilla flavoring ingredient, and wheat, oats, corn, or barley flakes, or combinations thereof. One or more additional flavoring ingredients may be included such as mint, cinnamon, peppermint, or maple syrup. The coffee product may be individually packaged for single cup dipping. A second version of the coffee product includes ground roasted coffee and a plurality of elongate, non-toxic flow-facilitating members in the form of spaghetti, macaroni, noodles, or a combination thereof which facilitate flow of brewing water through the product during drip brewing. The pasta product also raises the pH of the coffee beverage brewed therewith to reduce acidity thereof.

The invention relates to a coffee beverage composition being devoid of significant contents of oil and insoluble particulates, comprising(a) at least 15% based on the total weight of coffee solids of total mannose, wherein the free mannose content is less than 50% by weight of the total mannose content, and(b) less than 1,000 ppm on a total coffee solids basis of 5-hydroxymethyl furfural, and to a process for producing a soluble coffee extract, comprising the steps:(i) combining roast and ground coffee with water,(ii) adding hydrolase enzymes,(iii) wet-milling to a mean particle size of about 10 to about 250 μm,(iv) treating the reaction mixture by exposing it to a temperature in the range of about 20° C. to about 90° C., preferably about 50° C. to about 60° C., and(v) circulating the reaction mixture through a cross-flow semi-permeable membrane separation device where the soluble coffee extract is obtained as permeate.

The invention discloses a drinking water machine with a coffee function. The machine comprises a drinking water machine, a coffee module and a control circuit, wherein a first water path port and a first circuit port are formed on the drinking water machine; a second water path port and a second circuit port are formed on the coffee module; the first water path port and the first circuit port of the drinking water machine are connected and combined with the second water path port and the second circuit port respectively; and the coffee module is movably arranged on the drinking water machine. The machine can make coffee by utilizing coffee beans, adopts butting assembly, is convenient to operate, can move the coffee machine to clean at any time, has a simple and reliable structure, is easy to assemble, and saves placement space.

The invention discloses a method for retaining aroma of roasted coffee by utilizing fixative and belongs to the field of roasted coffee processing in food processing. By adding specified fixative of specified proportion during the roasting process of green coffee beans, the aroma of roasted coffee becomes stronger and the taste becomes mellower under the condition that the production cost is not increased or slightly increased. The method is characterized in that butter is added as the fixative during the roasting process of the green coffee beans when the whole green coffee beans become orange to light coffee; other matters needing attention are the same as those of the common roasting methods of coffee; and the adding proportion is calculated by the weight and particularly the adding proportion is 2% of the green coffee beans.

The invention relates to a method for wet extraction of oily components from coffee beans and / or of residual materials of coffee production, wherein the coffee beans and / or the residual materials are extracted with a residual moisture content of 10 to 95 mass%, measured relative to the total weight of the coffee beans and / or residual materials of coffee production, using an extraction agent mixture that consists of at least one polar and one non-polar solvent each.

A coffee processing apparatus (100, 200, 300) is disclosed that comprises at least one of a grinding stage (110) for grinding coffee beans (10) into ground coffee beans (20); and a brewing stage (140) for brewing coffee from ground coffee beans; the coffee processing apparatus further comprising a sensor (150) arranged to sense a total concentration of volatile organic compounds released by said coffee beans or ground coffee beans; and a controller (160) responsive to said sensor and arranged to control said grinding stage and / or said brewing stage as a function of said total concentration. Methods of controlling such a coffee processing apparatus are also disclosed.
