冬、夏季6种经济贝类脂肪酸组成

Fatty acids profile of six marine shellfishes in summer and winter

    摘要
  • 摘要: 测定和比较了广东湛江地区6种常见经济贝类冬、夏季19种主要脂肪酸组成，探讨了冬、夏2季气候变化对贝类脂肪酸组成的影响和相应的脂肪酸营养价值。结果表明，检测的6种海洋贝类冬、夏季总脂含量分别为（0.110.01）%~（0.190.01）%，（0.150.00）%~（0.450.04）%；饱和脂肪酸（SFA）分别为35.15%~47.29%，41.96%~45.99%；单不饱和脂肪酸（MUFA）分别为9.47%~17.68%，13.62%~18.04%；多不饱和脂肪酸（PUFA）分别为39.35%~48.56%，36.25%~43.15%。通过方差分析，6种贝类冬季SFA、MUFA和PUFA的含量均比夏季高，且具有显著差异；冬季的总脂含量虽然比夏季高，但差异不显著。

     

    Abstract: The paper measured and compared compositions of 19 fatty acids of six marine shellfish species in Zhanjiang, Guangdong Province of China, in summer and winter by using GC-MS, and the influences of climate changes in these two seasons on the fatty acids' composition and nutritional value were discussed as well. The results showed that the lipid content of the marine shellfish species studied were (0.110.01)%~(0.190.01)% (summer) and (0.150.00)%~(0.450.04)% (winter); saturated fatty acids were 35.15%~47.29% (summer) and 41.96%~45.99% (winter); monounsaturated fatty acids were 9.47%~17.68% (summer) and 13.62%~18.04% (winter); polyunsaturated fatty acids were 39.35%~48.56% (summer) and 36.255%~43.15% (winter). Therefore, SFA, MUFA and PUFA contents were significantly higher in winter than in summer, and the total lipid percentage was also higher in winter than in summer, but not significant.
