Abstract: Coffee aroma gases are conveyed to a cryogenic collector in which liquid nitrogen is sprayed directly into the aroma gas stream to rapidly condense the aroma gas and form finely divided particles of coffee aroma frost suspended in a stream of nitrogen gas, while minimizing contact of the cooled gas with the walls of the collector. The suspension of aroma frost particles in gaseous nitrogen is passed through a tubular porous filter to remove the aroma frost particles which collect on the outer surface of the tubular filter, with the nitrogen gas passing through the porous filter and being exhausted from the collector. The porous filter is periodically back pulsed to dislodge aroma frost particles collected on the outer surface of the tubular filter, with the particles being recovered for incorporation in soluble coffee products.

Abstract: The present invention relates to a process to recover beneficial coffee volatiles such as diacetyl and acetaldehyde from an aroma stream generated by the thermal hydrolysis of spent grounds. The aroma stream is passed over a bed of a non-polar microporous adsorbent and effluent is collected until breakthrough of furfural is detected. The invention also relates to the composition of the recovered/purified coffee aroma and to soluble coffee products containing the coffee aroma.

Abstract: A process for preparing a liquid aroma containing concentrated coffee aromatic compounds from a grinder gas frost is described. A higher yield of coffee aromatics is enabled, and these aromatics are of a higher quality. Further, the liquid aroma produced is essentially carbon dioxide free. The liquid aroma may be used to aromatize coffee powders, glycerides or other food substrates. Coffee powders aromatized with the liquid aroma are described as having a "buttery" "roasted and ground" coffee aroma.

Abstract: A method for the direct condensation of gaseous food volatiles, such as coffee aroma, on a food substrate, such as coffee, at cryogenic temperatures. A bed of particulated solid substrate is placed in a vessel cooled by a cryogenic fluid such as liquid nitrogen. The substrate is fluidized to provide an adsorbent bed thereof. Gaseous aroma volatiles are then adsorbed onto the cooled and fluidized bed of substrate having a temperature preferably below -150.degree. F. The aromatized substrate formed is preferably equilibrated to insure uniformity of aromatization, binding of volatiles to the substrate and storage stability. The resultant aromatized substrate can then be added to unaromatized food material for aroma and/or flavor enhancement.

Abstract: Grinder gas aroma evolved from the comminution or fracturing of freshly roasted coffee beans is stabilized by condensing the gas and adding an oxygen scavenger to the condensate. This condensate is then briefly contacted and extracted with a fluorinated-chlorinated hydrocarbon to remove harsh aroma compounds and then with a mixture of non-polar and polar solvents in order to extract desirable aromatics. This extract is stable at freezer temperatures and can be used to aromatize coffee or coffee-like products.
Abstract translation: 从新鲜焙炒的咖啡豆的粉碎或压裂产生的研磨机气体芳香通过冷凝气体并向冷凝物中加入除氧剂来稳定。 然后将该缩合物短暂地接触并用氟化氯化烃萃取，以除去苛刻的芳香化合物，然后用非极性和极性溶剂的混合物萃取所需的芳族化合物。 该提取物在冷冻室温度下稳定，可用于使咖啡或咖啡状产品芳香化。
