Abstract

The aim of this study was investigation the effects of different methods (wet pressing: WP and supercritical fluid extraction: SFE) of oil extraction from lantern fish (Myctophidae) in terms of quantity and quality. Results showed there was no significant difference in oil production rate (p>0.05), but there was a significant difference between detected volatile components (alkanes, aldehydes, amines and acetic acid) (p<0.05). Some of Neutral lipids (Wax Esters (WE), Triacylglycerol (TAG) and Free Fatty Acids (FFA)) showed significant difference (p<0.05) and Cholesterol (CHOL) levels did not show significant differences between treatments (p<0.05). Also, fatty acid profiles showed the level of DHA in SFE treatment was significantly higher than WP (p<0.05). The acidity value (AV) did not show a significant difference (p<0.05). Also, the amount of heavy metals (Mercury (Hg), arsenic (As), cadmium (Cd) and lead (Pb)) in extracted oils by SFE was lower than the other method (p<0.05). Therefore, the results of this study indicate the potential of lantern fish for extraction of fish oil in human consumption and the SFE method for extracting it.

超临界CO2对Myctophildae鱼油脂提取量和质量的影响及其与湿法压榨的比较

本研究的目的是研究不同方法（湿法：WP和超临界流体萃取：SFE）从数量和质量上对灯笼鱼（Myctophidae）油脂提取的影响。结果表明，油的产率没有显著差异（p>0.05），但检测到的挥发性成分（烷烃、醛类、胺类和乙酸）之间有显著差异（p<0.05），三酰甘油（TAG）和游离脂肪酸（FFA））显示出显著差异（p<0.05），胆固醇（CHOL）水平在处理之间没有显示出显著差别（p<0.05，SFE法提取的鱼油中重金属（汞、砷、镉和铅）的含量低于其他方法（p<0.05）。因此，本研究结果表明灯笼鱼提取人类食用鱼油的潜力和SFE法的提取潜力。

期刊介绍： Turkish Journal of Fisheries and Aquatic Sciences" (TrJFAS) is a refereed academic journal has been published by Central Fisheries Research Institute of Turkey and Japan International Cooperation Agency (JICA), and published in English. It aims to address research and needs of all working and studying within the many varied areas of fisheries and aquatic sciences. The Journal publishes English language original research papers, critical review articles, short communications and technical notes on applied or scientific research relevant to freshwater, brackish and marine environments. TrJFAS was published biannually (April & November) between 2001 and 2009. A great number of manuscripts have been submitted to the journal for review from acceptance of the SCI index. Thereby, the journal has been published quarterly (March, June, September and December) from 2010 to 2017. The journal will be published monthly in 2018.
