The present invention relates to a method of producing an aromatized food or beverage product, wherein an aroma fraction is obtained from a plant extract, said aroma fraction is being contacted with an oil to remove undesired aroma compounds, and the aroma fraction from which undesired compounds have been removed are combined with a food or beverage composition to produce an aromatized food or beverage product.

Method of producing an aromatised food or beverage product

The present invention relates to a method for producing an aqueous liquid aromatised with aroma compounds from coffee, wherein a gas comprising aroma from roast and ground coffee and water is condensed to provide a liquid aqueous phase and a gas phase; and the gas phase is subjected to pressurisation in the presence of an aqueous liquid. The liquid is useful e.g. in the production of soluble coffee products.

Method of producing an aromatised aqueous liquid

An aroma product resulting from the recovery of aroma components from coffee. A slurry of coffee grounds in an aqueous liquid is subjected to stripping for stripping aroma components from the slurry. The stripping is carried out using gas in a substantially counter-current manner to provide an aromatized gas containing aroma components. The aroma components are then collected from the aromatized gas. The aroma components may be added to concentrated coffee extract prior to drying of the extract. The coffee powder produced has much increased and improved aroma and flavor and contains higher levels of furans and diketones.

Aroma product resulting from recovery process

A process for the recovery of aroma components from coffee. A slurry of coffee grounds in an aqueous liquid is subjected to stripping for stripping aroma components from the slurry. The stripping is carried out using gas in a substantially counter-current manner to provide an aromatized gas containing aroma components. The aroma components are then collected from the aromatized gas. The aroma components may be added to concentrated coffee extract prior to drying of the extract. The coffee powder produced has much increased and improved aroma and flavor and contains higher levels of furans and diketones.

Aroma recovery process

A method of producing coffee particles containing entrapped aroma. Soluble coffee solids and up to 10% by weight water are introduced into a heating and mixing zone and to raise the temperature to about 85.degree. C. to about 130.degree. C. to form a molten mass. Aroma-containing substrate is introduced into the molten mass to form a molten mixture containing a gas under a pressure of about 2.0 MPa to about 7.0 MPa. The molten mixture is extruded into a pressure zone in which the pressure is greater than the pressure of the gas in the molten mixture and the molten mixture is retained in the pressure zone until it solidifies to form a hardened glass. The hardened glass is ground into coffee particles of size of about 0.5 mm to 3 mm.

Method of making coffee particles containing aroma

An emulsion preconcentrate which contains hydrolyzed coffee oil and a coffee aroma. The emulsion preconcentrate is mixed with soluble coffee powder to provide a soluble coffee product. Upon dissolution of the soluble coffee product in hot water, the emulsion preconcentrate spontaneously forms an oil-in-water emulsion including droplets in the microemulsion tange; the dispersed oil phase containing the aroma. This provides a burst of aroma.

Coffee aroma emulsion formulations

A method of encapsulating volatile aroma compounds in which an inert gas, such as carbon dioxide, is dissolved in an aromatized edible liquid, and the aromatized, gasified liquid is co-extruded with a molten carbohydrate material having a glass transition temperature of between 20.degree. C. and 80.degree. C. to provide a continuous stream having an outer shell of the carbohydrate material surrounding an inner core of the aromatized, gasified liquid. The continuous stream is extruded into a pressure chamber having a pressure higher than the internal pressure of the inert gas in the aromatized liquid core, and is maintained under such pressure until the carbohydrate shell has cooled to below the glass transition temperature to provide capsules having a shell of hardened amorphous carbohydrate glass surrounding an inner core of gasified, aromatized liquid. When the capsules, which are incorporated in an instant consumer product, are contacted with hot water, the inert gas in the capsule core rapidly expands and ruptures the capsule wall, releasing aromatized liquid across the surface of the water. In accordance with a preferred embodiment, coffee aroma capsules are prepared from 100% coffee derived material, in which coffee aroma frost is dissolved in coffee oil and gasified, and the aromatized, gasified coffee oil is encapsulated in an outer shell of hardened amorphous coffee glass.

Encapsulation of volatile aroma compounds

An antifoam for incorporation with a vegetable extract is prepared by reacting a vegetable oil with calcium and magnesium cations which may be derived from ash of a vegetable material in an aqueous alkaline environment. The antifoam may be itself incorporated with a vegetable extract or may be mixed with a carrier oil and incorporated with liquid or dry vegetable extracts to form a vegetable extract composition of the present invention. Particularly useful in practicing the invention are extract, oil and ash derived from tea and coffee. Further advantages, particularly in the case of tea, derive from aromatics which may be incorporated in the carrier oil by contacting the carrier oil with an aqueous tea essence.
