    • 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.
    • 本发明涉及一种没有显着含量的油和不溶性颗粒的咖啡饮料组合物,其包含(a)基于总甘露糖的咖啡固体的总重量至少15%,其中游离甘露糖含量小于50% 总胆固醇含量的重量,和(b)基于咖啡固体的5-羟甲基糠醛总量小于1,000ppm,以及生产可溶性咖啡提取物的方法,包括以下步骤:(i)将焙炒和研磨的咖啡 用水,(ii)加入水解酶,(iii)湿研磨至约10至约250μm的平均粒度,(iv)通过将反应混合物暴露于约20℃的温度 至约90℃,优选约50℃至约60℃,和(v)使反应混合物循环通过交叉半透膜分离装置,其中获得可溶性咖啡提取物作为渗透物。
