中文摘要: 为揭示“六月黄”中华绒螯蟹食用部分（几乎全部为肝胰腺）的滋味品质特征，利用味觉分析系统，研究昆山市养殖池塘产雌、雄“六月黄”中华绒螯蟹肝胰腺的滋味特征。结果表明，新鲜蒸制的“六月黄”中华绒螯蟹肝胰腺的基本味味觉指标中，鲜味非常突出，其次是苦味和涩味。而其回味味觉指标中苦味回味最高，其次是涩味回味和鲜味回味。“六月黄”雌、雄蟹个体间，苦、涩味和苦味回味等味觉强度指标均有极显著差异（P<0.01）。相关线性判别分析的初始验证判别和交互验证回判的正确率均可达到100%。池塘养殖“六月黄”中华绒螯蟹肝胰腺滋味具有显著性别差异性，雄蟹的滋味特征显示出较雌蟹更为美味的趋势。
Abstract:The taste profile of the edible parts（almost all of which are hepatopancreas）of the Chinese mitten crab（Eriocheir sinensis）′Liuyuehuang′（juveniles）was studied.An taste sensing system was used to quantitatively evaluate the taste attributes of the hepatopancreas in the crabs from the aquaculture ponds near the Yangcheng Lake in Kunshan City，Jiangsu Province.It was revealed that umami was the predominant taste of the steamed crabs，followed by bitterness and astringency.The bitterness aftertaste had the highest taste-active value among three aftertastes，followed by astringency aftertaste and umami aftertaste.Male and female crab samples had significant differences（P<0.01）in the values of bitterness，astringency，and bitterness aftertaste.The linear discriminant analysis indicated that both the initial discrimination and the cross-validation had the discriminant accuracy as high as 100%，which could robustly distinguish between male and female crabs.The results demonstrated that significant gender differences existed in hepatopancreatic taste profiles of the crabs from aquaculture ponds near the Yangcheng Lake，and the male crabs were tastier than the female crabs.
