Hops are natural ingredients used to impart bitterness and flavor to beer. Recently, new varieties of hops have attracted global research attention. The Sorachi Ace variety, in particular, interests many craft brewers. This hop imparts characteristic varietal aromas, including woody, pine-like, citrus, dill-like, and lemongrass-like, to finished beers. Here, we investigated specific flavor compounds derived from Sorachi Ace using selectable one-dimensional or two-dimensional gas chromatography–olfactometry/mass spectrometry and head space-solid phase microextraction–gas chromatography–mass spectrometry. The results showed that a unique volatile compound, geranic acid, was present at a significant level only in the test beer brewed with the Sorachi Ace hop. Furthermore, sensory evaluation techniques revealed that geranic acid has very unique characteristics. This compound is not odor-active but functions as an enhancer for hop-derived terpenoids at subthreshold levels.

识别和香叶酸作为啤酒花的独特的风味化合物的表征（啤酒花L.）品种空知王牌

啤酒花是用于赋予啤酒苦味和风味的天然成分。最近，啤酒花的新品种引起了全球研究的关注。尤其是Sorachi Ace品种，吸引了许多精酿啤酒商。这种啤酒花为成品啤酒赋予了特征性的品种香气，包括木香，松木，柑橘，莳萝和柠檬草般的香气。在这里，我们使用可选的一维或二维气相色谱-嗅觉/质谱法和顶空固相微萃取-气相色谱-质谱法研究了源自Sorachi Ace的特定风味化合物。结果表明，只有在用Sorachi Ace啤酒花酿造的测试啤酒中，独特的挥发性化合物香叶酸才以显着水平存在。此外，感官评估技术显示，香叶酸具有非常独特的特征。该化合物不具有气味活性，但在低于阈值的水平上可作为啤酒花来源的萜类化合物的增强剂。
