摘要:
A flavorful soluble coffee is obtained by first evaporatively concentrating a coffee extract and condensing the bulk evaporate which is then vacuum stripped to obtain a condensate of from 5% to 15% by weight of the bulk evaporate. The condensed strippings are added to the concentrated extract which is then dried.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung einer Kapsel mit einer Beschichtung, zur Zubereitung eines Getränks durch Einbringen von Wasser. Das Verfahren umfasst die Schritte: (i) Bereitstellen eines Presslings aus einem Getränkepulver oder einem Getränkepulvergemisch, wobei der Pressling eine Oberfläche aufweist, die beschichtet oder unbeschichtet ist; (ii) in Kontakt bringen wenigstens eines Teils der Oberfläche, vorzugsweise der gesamten Oberfläche, des Presslings mit mindestens einem Polysaccharid, mindestens einem Vernetzungsmittel und mindestens einem Polyol zur Ausbildung einer Schicht; (iii) Trocknen der Schicht. Die in ii) und iii) aufgebachte Schicht wird mit einem Schwellgrad zwischen 20 % und 900%, vorzugsweise 60 % bis 850 % und ganz besonders bevorzugt zwischen 100 % und 800 % eingestellt; und/oder die Kapsel wird bei Kontakt mit Wasser um 0.3 % bis 6 %, vorzugsweise 0.5 % bis 5.5 % und ganz besonders bevorzugt 1.0 % bis 4.0 % ausgedehnt.
摘要:
The present invention relates to a system for extracting/isolating a caffeine-rich powder from the silverskin which surrounds the coffee seed/bean using an apparatus comprising at least one chamber for premixing distilled water and silverskin (1), one ultrasonic extraction cell (2) comprising at least one module (2a) comprising at least one acoustic transducer (14) and one acoustic radiator (16), at least one mechanical separation tank (3), at least one drying unit (4) and at least one monitoring/control unit of the apparatus (5), wherein the caffeine-rich powder is extracted/isolated as a result of the breakdown of the silverskin molecular structure by the acoustic energy generated by the vibratory movement of the acoustic radiator and actuated by the acoustic transducer, and as a consequence of the caffeine chemical affinity for the distilled water.
摘要:
Shown is a method of making a coffee concentrate, and a coffee concentrate obtainable by the method. The method involves primary and secondary extraction, with split tapping of the primary extract into a first and second primary draw off. The extraction is conducted under such conditions as to satisfy a minimum mass transfer Fourier number, and a minimum ratio of the extraction yield of the first primary draw-off to the extraction yield obtained in all extraction sections.
摘要:
The present invention relates to the preparation of a coffee beverage powder useful for the preparation of coffee beverages such as e.g. cappuccino, café latte, café macchiato, café au lait. The method comprises the preparation of an aqueous composition comprising coffee solids and protein and/or fat, adding aroma obtained from coffee to the composition and drying the composition to produce a coffee beverage powder. The coffee beverage powder has improved aroma and/or characteristics.
