IMPROVED METHOD FOR ISOMERISATION OF HOP ALPHA-ACIDS TO ISO-ALPHA-ACIDS |
摘要 |
<p>The invention relates to a process for the production of iso-alpha-acids starting from alpha-acids in which an alpha-acid containing hop extract is mixed with a carbon-containing chemical compound with one or more functional groups containing a (basic) nitrogen atom with a lone pair (or mixtures thereof), either in solvent-free conditions or in the presence of solvents and preferably under an oxygen-free atmosphere. The resulting mixture is subjected to a temperature of at least 278 K for a time sufficient to effect the intended conversion of the alpha-acid reactant into the iso-alpha-acid product. The present invention further relates to iso-alpha-acid compositions obtained by said improved isomerisation process and to the use of said iso-alpha-acid compositions as bittering formulation and/or as source to obtain reduced or hydrogenated iso-alpha-acid compositions.</p> |
