摘要:

分析和评价浙江舟山(ZS)、浙江温州(WZ)、福建厦门(XM)、广东湛江(ZJ)4 个不同地理群体曼氏无针乌贼的营养成分。用常规方法检测曼氏无针乌贼肌肉的一般营养成分,采用全自动氨基酸自动分析仪测定氨基酸含量;采用气相色谱-质谱联用仪测定脂肪酸含量;采用原子吸收光谱仪测定无机元素含量。结果表明:蛋白质含量和能值以WZ最高;碳水化合物含量以ZS最高;各地理群体曼氏无针乌贼干物质中氨基酸含量由高到低的顺序为ZJ((64.08±1.05)%)>XM((63.97±0.94)%)>WZ((63.90±0.84)%)>ZS((63.39±0.67)%);必需氨基酸/总氨基酸比率在33.90%~34.32%之间,必需氨基酸指数以ZJ最高;风味氨基酸的含量较高,变化范围为(32.32±0.56)%~(32.81±0.68)%;脂肪酸中ω-3、ω-6脂肪酸相对含量高;钙、铁、锌、镁等矿物元素含量丰富。不同地理群体的曼氏无针乌贼营养成分虽存在一定差异,但与其他头足类种类相比,曼氏无针乌贼是营养价值较高的海产品。

Abstract:

The aims of this study are to analyze and evaluate the nutrients of muscle in Sepiella japonica collected from four
geographic populations, Zhoushan (ZS), Wenzhou (WZ), Xiamen (XM), and Zhanjiang (ZJ) cities. The general nutrient
compositions were determined by routine methods, amino acid compositions by using amino acid analyzer, fatty acid
compositions by GC-MS and mineral contents by atom absorption spectroscopy (AAS). The results showed that the protein
contents and energy value of S. japonica from WZ were higher than those from three other areas. The maximal content
of carbohydrate was detected in ZS. The total levels of amino acids in S. japonica from different areas were arranged in
a descending order as followed: ZJ ((64.08 ± 1.05)%) > XM ((63.97 ± 0.94)%) > WZ ((63.90 ± 0.84)%) > ZS ((63.39 ±
0.67)%). The ratio of essential amino acids (EAA) to total amino acids (TAA) was in the range of 33.90%–34.32% and the
essential amino acid index (EAAI) of S. japonica from ZJ was the highest among four areas. The content of delicious amino
acids was abundant, which was in the range of (32.32 ± 0.56)% to (32.81 ± 0.68)%. The percentages of ω-3 and ω-6 PUFA
in total fatty acids were high and the content of Ca, Fe, Zn and Mg were also rich. Even though the nutritional compositions
were a little different in muscle of S. japonica from four wild populations, S. japonica is a kind of seafood with high
nutritional value when compared with other cephalopod species.
