Abstract
The present application discloses a novel and advantageous method for the preparation of essentially odor-free alkali metal tetrahydroisohumulate (THIH) which proceeds through isomerization of the essential alkali metal tetrahydrohumulate (THH) intermediate, which is in turn produced by the hydrogenation with two moles of hydrogen of a starting alkali metal humulate (H) at a pH of at least 10, the intermediate THH being thus produced with relative ease and in high yields and purity, which high yields and purity carry over to the ultimate end product, namely, to the essentially aroma-, odor-, and impurity-free THIH, which end product accordingly does not require steam-stripping or other cleanup procedure as is conventional for THIH produced from other sources or by other procedure.
