Qualitative Determination of Beta-Acids and their Transformation Products in Beer and Hop Using HR/AM-LC-MS/MS

Popis výsledku v původním jazyce

Transformation products of beta-acids formed during their oxidation, mainly hulupones, have been shown to have an interesting kind of bitterness.Their structuree were elucidated using LC-TOFMS and 1D/2D NMR in solution after thermal treatment of the hopbeta-acids. This study demonstrates thw advantages of MS detection with high resolution and accurace mass measurements.The structure of transformation products in an experimental solution of oxidized beta-acids was elucidated using a newly developed method by hybrid quadrupole-Orbitrap MS. In adition to already known structures, two new ones were identified and named epoxycohulupone and epoxyhulupone.
