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.

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.
