摘要
目的测定广东湛江海域4种?科鱼肌肉中脂肪酸含量。方法用0.5%硫酸-甲醇溶液将鱼肌肉中脂肪酸甲酯化,气相色谱法测定脂肪酸甲酯含量。结果 4种?科鱼肌肉中饱和脂肪酸、单不饱和脂肪酸、多不饱和脂肪酸含量分别为39.12%~44.89%、23.76%~35.95%、20.27%~35.23%。结论湛江海域4种?科鱼肌肉中均有丰富的多不饱和脂肪酸,具有较高的营养价值。
Objective To determine the content of fatty acids in the muscle of 4 Terapontidae species in Zhanjiang coastal waters. Methods The fatty acids in the muscle were methyl esterified by 0.5% sulfuric acid/methanol solution, and the levels of fatty acid methyl esters were determined by gas chromatography. Results The contents of saturated, monounsaturated, and polyunsaturated fatty acids were 39.12%-44.89%, 23.76%-35.95%, and 20.27%-35.23% in the muscle of 4 Terapontidae species, respectively. Conclusion The polyunsaturated fatty acids are abundant in the muscle of 4 Terapontidae species in Zhanjiang coastal waters, suggesting of high nutritional value.
