Martins, Zita E. published the artcileA chemometric approach to compare Portuguese native hops with worldwide commercial varieties, Category: esters-buliding-blocks, the main research area is hops linalool headspace solid phase microextraction GC mass spectrometry.
A diversity of native hops can be found in Portugal, but little is known concerning their volatile and sensory profiles. Nowadays, the exponential growth of the craft beer sector and the preference for more flavoured beers promote the research of unexplored wild hops that have the advantage of being well adapted to the Portuguese edaphoclimatic conditions. Therefore, the goal of this study was to characterize the volatile profile of 75 native Portuguese hops and compare with 34 com. varieties by means of headspace solid-phase microextraction gas chromatog./mass spectrometry (HS-SPME-GC/MS), in order to select those that present similarities with commercialized hops and confirm by check-all-that-apply (CATA) anal. if they present similar organoleptic characteristics. Due to the complexity of hop volatile profile and the great number of samples analyzed, robust chemometric treatment of chromatog. and sensorial data was required to make reliable conclusions. Twelve Portuguese hops present a volatile profile and sensory characteristics quite similar to some com. varieties, because 11 Portuguese hops were grouped with the European varieties Challenger, Hallertauer Magnum and Perle, both in volatile profile and sensory anal. and one clustered with American registered varieties.
