  • Patent number: 10258059
    Abstract: Disclosed is a novel instant coffee comprising aromatized soluble particles and a method of aromatizing soluble coffee particles. The soluble coffee particles are mixed with roast whole beans, and the mixture is held for at least two days. The result is aromatized soluble coffee particles, as evidenced by the presence of relatively high amounts of 2-methylpyrazine in instant coffee comprising said particles. The instant coffee has a favorable content in aroma components, yet with a low oil content.

  • Publication number: 20180177206
    Abstract: Disclosed is a process for the production of aromatized soluble coffee particles. The process comprises the incubation of an aroma donor, such as a roasted coffee, with a acceptor, such as a refined coffee oil. The acceptor can be added prior or after incubation to the soluble coffee particles. The disclosure of the present technology also pertains to a process for the preparation of an instant coffee product comprising aromatized soluble coffee particles. Thereby an odor-acceptable edible oil is subjected to aroma transfer from roast coffee beans, either before or after being applied on soluble coffee particles. The aroma transfer being conducted for an incubation time of at least one day, and the amount of the aromatized oil in the instant coffee is 0.8 wt. % to 4.5 wt. %.

  • Publication number: 20150327567
    Abstract: The present disclosure relates to a process for the production of a liquid coffee concentrate that has an improved storage stability at ambient temperature. The process comprises separating coffee extract resulting in a high aromatic coffee extract and a low aromatic coffee extract and subjecting the low aromatic coffee extract to a heat treatment and, optionally, a pH rising step.
