Extraction of oil from wet Antarctic krill (Euphausia superba) using a subcritical dimethyl ether method

Abstract

In this study, a novel method for obtaining high-quality krill oil from wet Antarctic krill by using subcritical dimethyl ether (SDE) was proposed.

Effects of ultrasound-assisted basic electrolyzed water (BEW) extraction on structural and functional properties of Antarctic krill (Euphausia superba) proteins

“…Antarctic krill is one of the most abundant biomass species in Southern Ocean, which is estimated at about 500 million metric tons [1] . Whole Antarctic krill contains 11.9–15.4% protein, 3% ash, 2% carbohydrates, 0.5–3.6% lipid and 77.9–83.1% water [2] .…”

Preparation of Liposomes from Soy Lecithin Using Liquefied Dimethyl Ether

“…Additionally, previous studies have shown that liquefied DME can extract a variety of functional substances, such as astaxanthin [50,51], fucoxanthin [52], lutein [29,53], resveratrol and its glycosides [54], catechins and caffeine [55], tocopherol [56], gingerols and capsaicin [27]. Among these substances, carotenoids, such as astaxanthin, fucoxanthin and lutein, are hydrophobic, therefore difficult to encapsulate into liposomes by mechanical methods.…”

Three‐liquid‐phase salting‐out extraction of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)‐rich oils from Euphausia superba

“…As reported previously, n‐3‐PUFAs‐integrated PLs are more proficiently incorporated and absorbed into cell membranes than triglycerides (TAGs) [11, 12]. The efficient incorporation of KO into the cell membrane makes it a better choice than fish oil [12]. The EPA and DHA are omega‐3 polyunsaturated fatty acids which are the important component of the human cerebral cortex, skin, and brain [13–15].…”

“…These diverse lipids classes are mainly characterized by phospholipids (PLs) integrated with docosahexaenoic acid (DHA, C22:6, n‐3) and eicosapentaenoic acid (EPA, C20:5, n‐3) [1, 3]. As reported previously, n‐3‐PUFAs‐integrated PLs are more proficiently incorporated and absorbed into cell membranes than triglycerides (TAGs) [11, 12]. The efficient incorporation of KO into the cell membrane makes it a better choice than fish oil [12].…”
