  • Patent number: 5972409
    Abstract: A soluble coffee is prepared from ground green coffee which is extracted with water, the green extract obtained is dried and green powder obtained by drying is passed into and through a twin-screw extruder, and while the powder is passed through the extruder, the powder is heated in the extruder at a temperature of from 130.degree. C. to 240.degree. C. for up to 5 minutes to obtain a heat-caramelized extrudate product from the extruder, and that product is cooled and thereafter dried and ground to provide a powder-form product. Additionally, obtaining green extracts from low temperature and high temperature split extraction enables separate processing of low and high temperature extracted extracts, and low temperature extracted extracts may be heated in an extruder at a temperature of from 180.degree. C. to 240.degree. C. and high temperature extracted extracts may be heated in an extruder at a temperature of from 130.degree. C. to 180.degree. C. which enables obtaining a balanced product.

  • Patent number: 5958497
    Abstract: A water-soluble carmelized chicory product has a composition which includes, by weight, an inulin content between 40% and 65%, a reducing sugar content between 4% and 10% and a combination of fructose and glucose of less than 5% and which provides a depth of color, as described below, between 1.0 and 2.5. The product is prepared by extracting kiln-dried chicory with water to obtain an extract or by pressing chicory root to obtain an extract, the extract is heated in a tubular extractor to hydrolyze a part of the extract inulin content to increase extract reducing sugar content, the heat-treated extract is dried to obtain a powder, the powder is passed through an extruder and subjected to a temperature between 180.degree. C. and 250.degree. C. to obtain a caramelized product, and the carmelized product is cooled and then ground to obtain the water-soluble chicory product.
