The present invention refers to a process for extracting arabinogalactans from coffee beans comprising pre-treating the beans with water at 10 to 95~C for between two hours and one week and then enzymatically hydrolysing whole or ground green or roasted coffee beans thereby obtaining an aqueous dispersion comprising partially hydrolysed coffee beans and arabinogalactans. Furthermore, the invention also encompasses the use of coffee-derived arabinogalactans products where the coffee derived arabinogalactans are used such as a glassy matrix, pure soluble coffee and a beverage composition.
L'invention concerne un procédé permettant d'extraire des arabinogalactanes de grains de café, qui consiste à prétraiter les grains avec de l'eau à une température comprise entre 10 et 95 ·C pendant une durée allant de deux heures à une semaine et, ensuite, à hydrolyser enzymatiquement l'ensemble des grains de café moulus verts ou torréfié, produisant ainsi une dispersion aqueuse comprenant des grains de café et des arabinogalactanes partiellement hydrolysés. De plus, l'invention concerne l'utilisation de produits d'arabinogalactanes dérivés du café dans lesquels les arabinogalactanes dérivés du café sont utilisés tels que pâte vitreuse, café soluble pur et composition de boisson.
