摘要
以细点圆趾蟹加工过程中产生的副产物水煮液为研究对象,测定其基本营养成分、矿物元素、氨基酸组成、非挥发性呈味物质和挥发性风味物质,分析水煮液的营养及风味特性。结果表明:水煮液固形物中粗蛋白质(74.36%)和灰分含量(23.92%)较高,脂肪含量(0.42%)较低。氨基酸总量为75.08 g/100 g蛋白质,其中谷氨酸含量最高(12.68 g/100 g蛋白质)。矿物质含量比例均衡。甜味氨基酸(占游离氨基酸的69%)、甘氨酸甜菜碱和氯离子是水煮液滋味的主要贡献者。挥发性风味成分中含量最高的是芳香类物质(29.61%),醛类和酮类化合物是水煮液风味的主要贡献者。
General composition, minerals, amino acids, non-volatile taste compounds and volatile components of boiled liquid that made from by-products of Ovalipes punctatus were detected and also evaluated for characteristics of nutritional and flavor. The results showed as follows: boiled liquid contained high amount of crude protein and minerals, low amount of crude fat in soluble solids. The protein contained high amount of amino acids (75.08 g/100 g protein) and the amino acids found at highest concentration was glutamic acid(12.68 g/100 g protein). The boiled liquid was well-bal- anced in mineral composition. Sweety amino acids (69% of total free amino acids), glycine betaine and C1- were main contributors to the taste of boiled liquid. Aromatic compounds (42.05%) took the largest percentage in all volatiles, while aldehydes and ketones compounds contributed the flavor characteristics of crab boiled liquid.
