Abstract
Processes for isolating bitter compounds for use in food and beverage products entailing contacting a bitter compound composition with an adsorbent to adsorb bitter compounds from the bitter compound composition, desorbing the bitter compounds from the adsorbent to obtain a bitter compound isolate, and adding the bitter compound isolate to a food or beverage product to enhance the flavor thereof.
Claims20
A process for isolating bitter compounds for use in food and beverage products comprising:
- a. contacting a bitter compound composition with an adsorbent to adsorb bitter compounds from the bitter compound composition;
- b. desorbing the bitter compounds from the adsorbent to obtain a bitter compound isolate;
- and
- c. adding the bitter compound isolate to a food or beverage product to enhance the flavor thereof.
A process for isolating bitter compounds for use in food and beverage products comprising:
- a. extracting a bitter compound composition with a solvent to remove bitter compounds from the bitter compound composition;
- b. removing the solvent from the bitter compound composition to obtain a bitter compound isolate;
- and
- c. adding the bitter compound isolate to a food or beverage product to enhance the flavor thereof.
A bitter compound isolate for enhancing flavor of food and beverage products comprising at least one compound selected from the group consisting of 3-O-caffeoyl-γ-quinide, 4-O-caffeoyl-γ-quinide, 5-O-caffeoyl-epi-δ-quinide, 5-O-caffeoyl-muco-γ-quinide, 3-O-feruloyl-γ-quinide, 4-O-feruloyl-γ-quinide, 3,4-O-dicaffeoyl-γ-quinide, 4-O-caffeoyl-muco-γ-quinide, 3,5-O-dicaffeoyl-epi-δ-quinide, 4,5-O-dicaffeoyl-muco-γ-quinide, 5-O-feruloyl-muco-γ-quinide, 4-O-feruloyl-muco-γ-quinide, 5-O-feruloyl-epi-δ-quinide, 3,4-O-diferuloyl-γ-quinide, 3,5-O-diferuloyl-epi-δ-quinide, 4,5-O-diferuloyl-muco-γ-quinide;
- quinide esterified with one or more of caffeic acid, ferulic acid, p-courmaric acid, 3,4-dimethoxycinnamic acid;
- cis-5,6-dihydroxy-1-methyl-3-(3′,4′-dihydroxyphenyl)indan, trans-5,6-dihydroxy-1-methyl-3-(3′,4′-dihydroxyphenyl)indan, cis-4,5-dihydroxy-1-methyl-3-(3′,4′-dihydroxyphenyl)indan, trans-4,5-dihydroxy-1-methyl-3-(3′,4′-dihydroxyphenyl)indan, and mixtures thereof.
