In recent years, the butter crab (BC), a distinctive phenotypic variant of the female mud crab , has garnered increasing market attention due to its perceived superior nutritional and sensory attributes. This study conducted a comprehensive comparative analysis of the nutritional composition, textural properties, and sensory characteristics of BC and normal female mud crab (NFMC). Results showed that the muscle and hepatopancreas of BC contained significantly higher lipid contents (0.77 and 22.14 g/100 g wet weight) and elevated levels of DHA + EPA (18.36% and 12.86% of total fatty acids), which contributed to its characteristic orange-yellow coloration, as reflected by colorimetric values ( × × = 30.20 × 4.38 × 16.15). Sensory evaluation revealed that BC exhibited enhanced umami taste and aroma in both muscle and hepatopancreas, corresponding to higher concentrations of umami amino acids (0.75 and 1.95 mg/g wet weight) and aldehydes (35.06% and 34.37% of total volatiles), respectively. In addition, 80% of panelists preferred BC based on visual appearance, indicating its strong consumer appeal. Overall, this study advances our understanding of the biochemical and sensory profiles of BC and NFMC and provides important insights for market positioning of BC in the premium seafood sector.
近年来，黄油蟹作为雌性青蟹的一种独特表型变体，因其被认为具有优越的营养和感官特性而受到越来越多的市场关注。本研究对黄油蟹和正常雌性青蟹的营养成分、质地特性和感官特征进行了全面的比较分析。结果表明，黄油蟹的肌肉和肝胰腺含有显著更高的脂质含量（分别为0.77和22.14克/100克湿重）以及更高水平的DHA + EPA（分别占总脂肪酸的18.36%和12.86%），这导致了其特有的橙黄色，比色值（×× = 30.20×4.38×16.15）反映了这一点。感官评价显示，黄油蟹的肌肉和肝胰腺在鲜味和香气方面均有所增强，分别对应更高浓度的鲜味氨基酸（分别为0.75和1.95毫克/克湿重）和醛类（分别占总挥发性物质的35.06%和34.37%）。此外，80%的评委基于视觉外观更喜欢黄油蟹，这表明其对消费者具有很强的吸引力。总体而言，本研究增进了我们对黄油蟹和正常雌性青蟹生化和感官特征的理解，并为黄油蟹在高端海鲜市场的定位提供了重要见解。
