Abstract: 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 ?m, (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.

Abstract: An instant dry mix composition produces a beverage having a two-toned foam on the surface upon reconstitution in a hot liquid. The composition includes a foaming creamer for producing a foam layer and a separately enclosed quick dissolving or dispersing flavor/color component and optional sweetener component. The density of the combined flavor/color component and optional sweetener component is higher than the density of the foam layer. A beverage is prepared by combining the foaming creamer and hot liquid until the foaming creamer dissolves and creates a foamed layer on the surface. The combined flavor/color component and optional sweetener component is then added. Upon stirring the resultant mixture, a two-toned effect results in the foam layer.

Abstract: A method of preparing coffee aromatizing compositions. A coffee aroma such as a coffee aroma frost is contacted with a volatile organic carrier liquid at a processing temperature at which the carrier is in the liquid state and at which any moisture present is in the form of ice, to effect fixation of the aroma into the carrier liquid. The carrier liquid has a freezing point below the processing temperature, a boiling point above the processing temperature, a vapor pressure of at least 0.01 mm Hg at 25° C. and atmospheric pressure, and a water solubility of not more than 10% by weight.

Abstract: A method for solubilizing partially extracted roasted and ground coffee in a fixed bed reactor in the absence of any added acid catalyst is disclosed. The hydrolysis is effective to achieve a soluble solids yield of about 55% to about 68% based on the original roasted and ground coffee and it effects minimal degradation of the soluble solids generated.

Abstract: A process for the condensation of a volatile-rich vapor stream produced by a stripping operation from a vegetable or fruit product or the extract thereof, which comprises the steps of:(i) condensing a major proportion of the water present in the vapor stream using a surface condenser with water as a coolant;(ii) subjecting the condensate of step (i) to further cooling in a heat-exchanger using water at a lower temperature than that of step (i) as the coolant; and(iii) contacting the cooled condensate from step (ii) with the vapor stream issuing from the condenser of step (i) in a countercurrent absorption column.The process is particularly applicable to the condensation of a volatile-rich water vapor stream containing coffee volatiles.
