摘要

黄油蟹前体是雌性青蟹非正常发育的一种特殊生长形态,通过对正常雌性青蟹和黄油蟹前体性腺组织的营养组成和风味物质进行测定和比较分析,初步了解黄油蟹前体的性腺品质。结果表明,黄油蟹前体的性腺指数、粗蛋白和粗脂肪显著偏低,灰分含量显著偏高(P<0.05),但二者水分含量无显著差别;黄油蟹前体性腺的必需氨基酸(essential amino acid, EAA)和氨基酸总量(total amino acid, TAA)均显著低于正常青蟹(P<0.05),然而黄油蟹的EAA/TAA及EAA/NEAA均高于正常青蟹,更符合FAO/WHO的推荐标准,表明其蛋白质质量较好;同时,黄油蟹前体性腺的矿物质总量显著高于正常青蟹(P<0.05),且Zn的含量较高(32.72 mg/100 g)。二者性腺的呈味氨基酸含量均无显著差别,但黄油蟹前体性腺的甘味氨基酸含量略高;此外,黄油蟹前体性腺中醛类物质及主要呈香物质含量较高。综上,黄油蟹前体性腺的营养品质并非完全优于正常雌性青蟹,但其在风味方面相对优于正常雌性青蟹。

Abstract

Precursor butter crab is a special growth-form of abnormal female mud crab. The nutritional compositions and flavor compounds in gonads of normal female mud crab and precursor butter crab were determined to preliminarily understand the gonad quality of precursor butter crab. The result showed that the gonado-somatic index (GSI), crude protein and fat contents in the gonad of precursor butter crab were significantly lower, and the ash contents were significantly higher(P<0.05), while the moisture contents were no significant difference compared with control group. Besides, compared to normal female mud crab, the essential amino acid (EAA) and total amino acid (TAA) contents in the gonad of precursor butter crab were significantly lower (P<0.05); however, the EAA/TAA and EAA/NEAA values of precursor butter crab were more comparable to the reference values recommended by FAO/WHO which indicating its better protein quality. Meanwhile, the mineral contents in the gonad of precursor butter crab were significantly higher (P<0.05), especially Zn content (32.72 mg/100g). Moreover, the taste amino acid contents in both gonads were no significant difference, while the sweet amino acid contents in the gonad of precursor butter crab were little higher. Furthermore, the aldehydes and main aromatic substance contents in the gonad of precursor butter crab were much higher compared with control group. In summary, the nutritional quality of gonad of precursor butter crab was not completely superior to normal female mud crab, while its flavor characteristics were relatively better.
