摘　　要：采用顶空固相微萃取方法对国产香型啤酒花品种札一的压缩花和液态CO2浸膏中的挥发性成分进行了分析,并测定了该啤酒花品种的总树脂、软树脂、硬树脂、α-酸、β-酸和啤酒花多酚等多项指标,并与国外优质香型花SAAZ的各项影响酿造性能的参数进行了比较。结果表明,札一啤酒花具有较低的α-酸含量(3.40%,w/w),其β-酸含量在3.50%(w/w),合葎草酮在α-酸中所占的比例为23.92%;挥发性成分中β-法呢烯的相对含量达到了11.52%(w/w),在浸膏中的相对含量更高(14.48%);α-香柠檬烯的含量在压缩花和浸膏中分别为0.90%和1.56%,与国际优质香型啤酒花的含量指标相符合,表明札一具有优质香型啤酒花的品质,其液态CO2浸膏基本保持了压缩花的风味特征。lid-phase micro extraction （SPME）. Multiple indexes including total resin, soft resin, hard resin, α-acid, β-acid, and polyphenols in SA-1 hop were measured and then the parameters of SA-1 influencing beer brewing were compared with foreign quality hop SAAZ. The results suggested that SA-1 hop had lower content of α-acid（3.40 % w/w）,its content of β-acid was 3.50 %（w/w） and co-humulone ratio was 23.92 % rel. The content of β-farnesene was 11.52 % rel for compressed hop and 14.48 % for hop extract,and the content of trans-α-bergamotene was 0.90 % for compressed hop and 1.56 % for hop extract, which was close to that of foreign quality hop. The data showed that SA-1 hop had high quality, and its liquid CO2 hop extract almost kept the same flavoring characteristics as its compressed hop.
