摘要：
The invention relates to a coffee beverage composition being devoid ofsignificant contents of oil and insoluble particulates, comprising (a) atleast 15% based on the total weight of coffee solids of total mannose, whereinthe free raannose content is less than 50% by weight of the total mannosecontent, 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 coffeeextract, comprising the steps: (i) combining roast and ground coffee withwater, (ii) adding hydrolase enzymes, (iii) wet-milling to a mean particlesize of about 10 to about 250 ~m, (iv) treating the reaction mixture byexposing it to a temperature in the range of about 20~C to about 90~C,preferably about 5O~C to about 60~C, and (v) circulating the reaction mixturethrough a cross-flow semi-permeable membrane separation device where thesoluble coffee extract is obtained as permeate.
