Tuna livers, which are currently discarded in the fish industry, are a valuable source of marine oil rich in n‐3 polyunsaturated fatty acids (PUFAs), vitamin A, and vitamin D. In this study, subcritical dimethyl ether extraction (SDEE) is applied in the extraction of oil from high‐moisture tuna livers. Furthermore, other different extraction methods including wet reduction (WR), enzymatic extraction (EE), and supercritical carbon dioxide fluid extraction (SFE‐CO2) are used for comparisons, to assess the effect of different extraction methods on yield, oil quality, flavor (volatile compounds and sensory assessing), vitamin contents, and fatty acids composition. Compared with traditional methods, the high‐quality liver oil can be obtained with excellent yields by SDEE and SFE‐CO2, because they can prevent the oxidation of lipids, and, reduce the damage of PUFAs and vitamins effectively. Furthermore, only minor differences in volatile compounds and vitamins contents are observed between SDEE‐oil and SFE‐CO2‐oil, which is attributed to the differences in solubility to the solvents used. The oil with higher contents of vitamin A and α‐vitamin E can be obtained by SDEE. The main limitations of SFE‐CO2 are energy‐consuming due to high pressure used and the necessary pre‐treatment of freeze‐drying. However, these drawbacks could be overcome in SDEE because the pressure employed in SDEE is quite low (0.8 MPa) and the freeze‐drying is unnecessary. Therefore, SDEE would be a simple, effective, and promising technique to obtain the high quality oil rich in n‐3 PUFAs and vitamins in the fish oil industry. Practical Applications: Subcritical dimethyl ether extraction (SDEE) is a rising technology in oil extraction. It can extract oil from the high‐moisture materials without freeze‐drying under relatively low pressure. As is known, freeze‐drying is a necessary pre‐processing step in ordinary sub‐ and super‐critical fluid extraction. The high quality of oil can be obtained by SDEE, similar with the quality of the oil obtained by supercritical fluid extraction, with dramatically declined operational costs. Subcritical dimethyl ether extraction (SDEE) can extract oil from the high moisture tuna livers without freeze‐drying under relatively low pressure. Furthermore, the quality of SDEE‐oil is similar to the quality of oil obtained by supercritical carbon dioxide extraction, but substantially better than the oil obtained by wet reduction and enzymatic extraction.

“…SFE, which uses supercritical fluid (SF), that is, commonly supercritical carbon dioxide (scCO 2 ) as the extraction solvent, is an environmentally friendly extraction technique with high efficiency . Since SF has a high mass transfer rate and powerful solubility, SFE shows excellent extraction ability for the low boiling lipophilic compounds with low polarity . Moreover, the application range of SFE has been widened to the analytes with medium polarity by adding modifiers such as alcohols .…”

A lyophilization-supercritical fluid extraction coupled with supercritical fluid chromatography-quadrupole tandem mass spectrometry online method was developed for the determination of lipid mediators in breast cancer cells. Supercritical fluid extraction was applied to the cell samples for the first time due to the use of lyophilization. The conditions of supercritical fluid extraction and supercritical fluid chromatography-quadrupole tandem mass spectrometry were investigated systematically. Under the optimized conditions, all the calibration curves for the lipid mediators showed good linearity (correlation coefficient > 0.99). The limits of detection and the limits of quantification were in the range of 0.190-5.36 pg and 0.560-16.2 pg, respectively. The recoveries were in the range of 70.3-125%. The relative standard deviations of the precision ranged from 1.49-18.7% and the accuracies were higher than 84%. Compared with liquid-liquid extraction coupled with liquid chromatography and tandem mass spectrometry method, the present approach reduced the manual labor and obtained higher sensitivity as well as higher extraction recoveries for all 15 lipid mediators. Finally, the online method was applied to the quantification of lipid mediators in breast cancer cells and normal mammary epithelial cells. On the basis of the results, this lyophilization-supercritical fluid extraction online coupled with supercritical fluid chromatography-quadrupole tandem mass spectrometry method showed great promise in the analysis of lipid mediators in complex biological samples.

“…Valorization of fish processing wastes, for instance extracting such valuable oil, is subject of recent studies (Carsuo, 2015;Fiori et al, 2012;Nascimento et al, 2015;Nazir, Diana, & Sayuti, 2017). Various extraction methods have been proposed to extract oil from seafood wastes (Cyprian et al, 2016;Deepika et al, 2014;Hao et al, 2015;Laila, Wahidu, & Tajul, 2014). One of the most common methods for maintaining food quality as well as controlling oxidation, enzymatic, chemical, and microbial activity is freezing (Anoosheh, Hosseini, & Mirsadeghi, 2015;Aubourg, 2001;Ghaly, Dave, Budge, & Brooks, 2010;Karungi, Byaruhanga, & Muyonga, 2004).…”

Oil extracted from fish waste is considered as a value‐added product. The effect of postmortem processing times (0, 3, 6, and 9 hr) and blanching methods (sodium chloride, pH shift, and high temperature) on the extracted oil from rainbow trout viscera was studied. Blanching was applied six hours prior to oil extraction to counteract the effects of delayed processing time and increasing the oil stability. Autolysis by digestive enzymes is main culprit of higher contents of free fatty acids, lipid oxidation, saponified compound, and saturation degrees in case of postponed oil extraction. Results showed that PV was increased after pH shift and high temperature blanching, while there were no significant differences by using salt blanching. The lowest amount of TBA, AV, Totox, and saponification index was observed in salt blanched treatment. The colorimetric values including L*, b*, and whiteness index were decreased after pH shift, whereas redness was increased. Unfavorable coloration could be attributed to the lipid oxidation process that giving rise nonvolatile decomposition products with carbonyl groups. Our results indicated that salt blanching could reduce the effects of delayed processing time and lead to higher quality value‐added product from rainbow trout viscera.
