“…In contrast, the solid fraction showed high amounts of SFAs, such as C 14:0 (13.90%), C 15:0 (3.04%), C 16:0 (39.02%), and C 18:0 (8.01%), as well as unsaturated fatty acids, including DPA (5.02%) and DHA (18.11%), corresponding to 90.10% of the total solid fraction. Long-chain SFAs and monounsaturated fatty acids with relatively high melting temperatures present in fish oil usually precipitate out of solution during winterization . However, this precipitate contains also some amount of omega-3 fatty acids.…”

“…Long-chain SFAs and monounsaturated fatty acids with relatively high melting temperatures present in fish oil usually precipitate out of solution during winterization. 43 However, this precipitate contains also some amount of omega-3 fatty acids. While fish such as mackerel, herring, sand eel, and sparling (European smelt) contain large amounts of omega-3 fatty acids in their oils, 44 the presence of other fatty acids seems to lead to stearin (undesirable high melting point parts of oil) formation during winterization.…”

Squalene and docosahexaenoic acid (DHA) have gained substantial market shares as dietary supplements and vital nutraceuticals due to their beneficial effects on human health. Marine fish are the main commercial source of these nutraceuticals, but a growing global demand, issues of sustainability, and an expanding vegan and vegetarian population have prompted the search for alternatives. Oils obtained from oleaginous microorganisms such as microalgae, diatoms, certain fungi, and thraustochytrids are alternatives to fish oils for omega-3 fatty acids. Among these, DHA is now being mined from thraustochytrids due to its highest proportion in their lipids; however, this strategy is not cost effective. One way to offset such elevated production costs is to simultaneously extract other high value-added biological products from these oleaginous microorganisms. Here, we propose a novel biorefinery process based on single-step purification of squalene from total lipids extracted from an oleaginous thraustochytrid cultivated on nonedible forest biomass. To render the process economically feasible and sustainable, additional squalene-free lipids were exploited for enrichment of DHA, whereas leftover lipids generated as byproducts during the process were tested as a novel biolubricant.

Docosahexaenoic acid (DHA) merupakan asam lemak omega-3 pada minyak ikan yang berperan penting dalam perkembangan otak dan retina. Minyak ikan kaya DHA belum diproduksi secara massal di Indonesia. Mata tuna yang menjadi hasil samping industri perikanan dapat menjadi sumber potensial DHA dan eicosapentaenoic acid (EPA). Minyak mata tuna dengan karakteristik tinggi DHA dan polyunsaturated fatty acid (PUFA) rentan mengalami oksidasi, sehingga proses pemurnian perlu dilakukan untuk menghilangkan pengotor penyebab oksidasi. Penelitian ini bertujuan untuk menentukan perlakuan pemurnian terbaik melalui parameter mutu minyak ikan guna menghasilkan minyak mata tuna dengan penurunan pengotor yang maksimal. Minyak mata tuna diperoleh melalui ekstraksi secara sentrifugasi. Minyak yang dihasilkan selanjutnya dimurnikan dengan beberapa tingkatan perlakuan permurnian, yaitu netralisasi (N1), netralisasi bleaching (N1B1), netralisasi bleaching netralisasi (N1B1N2), dan netralisasi bleaching netralisasi bleaching (N1B1N2B2). Pemurnian menggunakan jenis adsorben yang berbeda, yakni alumina aktif 8%, arang aktif 10%, dan magnesol XL 5%. Parameter yang dianalisis meliputi asam lemak bebas (FFA), bilangan asam, bilangan peroksida, anisidin, dan total oksidasi (TOTOX). Hasil penelitian menunjukkan bahwa perbedaan jenis adsorben dan perbedaan tingkat ekstraksi berpengaruh secara nyata (p<0,05) terhadap bilangan peroksida, bilangan anisidin, total oksidasi, asam lemak bebas dan bilangan asam. Perlakuan dengan tingkat pemurnian N1B1N2B2 dengan adsorben magnesol XL 5% merupakan perlakuan terbaik. Proses pemurnian menghasilkan penurunan paramater oksidasi mencapai 50-80% meskipun minyak yang dihasilkan masih belum sesuai standar.

“…Subsequent to the extraction of omega-3 fatty acids from primary materials via solvent and/or wet extraction processes, fatty acids are rened by distilling sh oil to remove impurities. 32,33 Nowadays, the extraction methods that are more environmentally sustainable, specically winterisation and supercritical uid extraction, are regarded as being of greater signicance. 34,35 However, despite the industry's primary focus on omega-3 fatty acids and PUFAs, over 30% of saturated fatty acids (SFAs) remain unexplored and underutilised.…”
