Abstract
Known coffee flavor compounds including methyl mercaptan, a molar excess of carbonyl compounds and furfuryl mercaptan are combined in an aqueous solution of an inert, water-soluble carbohydrate at a preferred level of less than about 3% and then promptly dried, such as by spray-drying. These compounds may be fixed either separately or together. The dried fixed enhancer material is then combined with soluble coffee solids and/or soluble coffee-like solids powdered foodstuffs.
Claims14
A method for preparing a soluble, enhanced coffee-flavored foodstuff, coffee and/or coffee-like product comprising the steps of:
- (a) adding methyl mercaptan and a molar excess of carbonyl compounds, including for each mole of methyl mercaptan 2 to 50 moles of acetaldehyde, 0.02 to 3 moles of a 4 to 5 carbon alkane aldehyde and 0.2 to 5 moles of a lower alkane .alpha.-diketone selected from the group consisting of 2,3-butanedione, 2,3-pentanedione and mixtures thereof, to an aqueous solution of a non-reactive fixative, said materials being added in a total amount less than 10% by weight of the fixative,
- (b) drying the solution from step(a),
- (c) adding furfuryl mercaptan to an aqueous solution of a non-reactive fixative at a level below about 1% by weight of the fixative,
- (d) drying the solution of step (c),
- (e) combining the dried materials from steps (b) and (d) with soluble particles of a powdered foodstuff, coffee and/or coffee-like material, such that furfuryl mercaptan is present in an amount of from 2 to 8 parts per million by weight of the combined material and also present in an amount of from 1:4 to 2:1 by weight of methyl mercaptan.
A method for preparing a soluble, enhanced coffee-flavored foodstuff, coffee and/or coffee-like product comprising the steps of:
- (a) adding methyl mercaptan, a molar excess of carbonyl compounds, including for each mole of methyl mercaptan 2 to 50 moles of acetaldehyde, 0.02 to 3 moles of a 4 to 5 carbon alkane aldehyde and 0.2 to 5 moles of a lower alkane .alpha.-diketone selected from the group consisting of 2,3-butanedione, 2,3-pentanedione and mixtures thereof, and furfural mercaptan in an amount of from 1:4 to 2:1 by weight of methyl mercaptan to an aqueous solution of a non-reactive fixation said materials being added in a total amount less than 10% by weight of the fixative.
- (b) drying the solution from step (a),
- (c) combining the said material from step (b) with soluble particles of a powdered foodstuff, a coffee and/or a coffee-like material such that furfuryl mercaptan is present in an amount of from 2 to 8 parts per million by weight of the combined material.
