ABSTRACT:
A method of converting alpha acids to hop flavors by exposing the alpha acids to an environment capable of substantially simultaneously isomerizing and reducing the alpha acids to form either THIAA or HHIAA. Another aspect of this invention is directed to a method of reducing hop flavors by exposing an isoalpha acid, a dihydroisoalpha acid or a mixture thereof to conditions suitable to reduce said acids to produce THIAA, HHIAA or a mixture thereof at a pH of about 5 to about 12 in a reaction inert, protic solvent. Yet another aspect of this invention is directed to a method of reducing hop flavors comprising exposing an isoalpha acid, a dihydroisoalpha acid or a mixture thereof to conditions suitable to reduce said acids to produce THIAA, HHIAA or a mixture thereof in a reaction inert, aprotic solvent.
