摘要：
The invention relates to a process for converting alpha acid and isoalpha acids to tetrahydroisoalpha acid. The process comprises isomerizing an alpha acid to produce isoalpha acid and hydrogenating the isoalpha acid in the presence of a noble metal catalyst wherein, the noble metal catalyst is added incrementally or continuously throughout the hydrogenation step. The invention also relates to tetrahydroisoalpha acids made by the above process.
