“…In this study, E/NE ratio for microencapsulated fish oil with 5%FPI and 10% FPI were determined as 0.92 and 0.95, respectively. These ratios were considerably higher than those of many unprocessed fish that previously reported by some researchers (Iwasaki and Harada, 1985;Özyurt and Polat, 2006;Mol et al, 2008;Gómez-Limia et al, 2021). These results indicated that ponyfish isolate have well balanced protein thanks to favourable E/NE ratio, and may be considered as a nutrient-rich coating material for microencapsulation process.…”

Fish protein isolates extracted from underutilised fish species were used for coating material of anchovy oils and their nutritive value was investigated in this study. For this purpose, Klunzinger’s ponyfish (Equulites klunzingeri) proteins were extracted by using pH shifting process. Micro particles were prepared with anchovy oil (Engraulis encrasicolus) as core material (10%), and as wall materials a ratio of 5% and 10% fish protein isolate (FPI) was used. Maltodextrin (DE: 18:20) was added to both groups in a ratio of 10%. The emulsions were fed immediately into a Buchi Mini Spray Dryer (B290, Switzerland). The inlet temperatures, feed rate and aspiration rate were maintained at 160 oC, 15 mL/min and 35m3/h, respectively. The lipid, protein and moisture contents of anchovy oil microcapsules containing 5% FPI and 10% FPI were found as 43.76-43.09%, 4.34- 9.82% and 3.95-3.92%, respectively. The main amino acids in microcapsule samples were lysine, glutamic acid, and leucine which constituted in the range of 349-578 mg/100 g sample for microcapsules containing 5% FPI, and 805-1547 mg/100 g sample for microcapsules containing 10% FPI. In addition to that, essential and non-essential amino acids (E/NE) ratio for microencapsulated fish oil with 5% FPI and 10% FPI were determined 0.92 and 0.95, respectively. As a result of this study, it can be concluded that the addition of fish protein isolate enhanced the nutritive value of microencapsulated fish oil

“…Generally, this proportion is extended from 1 to 4 in freshwater fish species, and 5 to 10 in marine fish species (Valfré et al, 2003). This is mainly due to the fact that freshwater fish species feed on plants and marine fish species feed on zooplankton, which are rich in PUFAs (Vlieg and Body, 1988;Gómez-Limia et al, 2021). All of the eels in our study were caught in the freshwater Orontes River.…”

Seasonal differences in the lipid contents and fatty acid composition of European Eels (Anguilla anguilla, Linnaeus 1758) caught from the Orontes River (Hatay, Turkey) were determined. High lipid levels, as well as ω-3 and ω-6 fatty acids, are important factors in product quality. High-content lipid values of European eels from the Orontes River differed between seasons (p<0.05). The fatty acid compositions of eels ranged from 5.91-8.03 g/100 g in saturated fatty acids (SFA), 10.59-14.08 g/100 g in monounsaturated fatty acids (MUFAs), and 2.19-3.52 g/100 g in polyunsaturated fatty acids (PUFAs). Those present in the highest proportions were palmitic acid (C16:

“…Lysine is an important EAA for the human body, known as the "growth amino acid," which plays an important role in promoting development and strengthening physique (Mezey et al, 2019). The average Arctic grayling content of lysine was 15.700 mg/g, higher than that of wild meagre (10.200 mg/g), farmed meagre (12.400 mg/g) (Saavedra et al, 2017), European eel (8.700 mg/g) (Gómez-Limia et al, 2021), and adult F. obscurus (9.150 mg/g) (Tao et al, 2012) but lower than that of wild Chinook salmon (17.600 mg/g) and wild sockeye salmon (19.300 mg/g) (Colombo & Mazal, 2020).…”

The biochemical composition of the muscle in Arctic graylings at three age stages was evaluated and compared. For conventional biochemical composition, there was no significant difference in the crude protein content among the three age stages, but the crude fat content in the 1 year old was significantly lower than that of the others (P < 0.05). For amino acids composition, there was no significant difference in the content of essential amino acids and delicious amino acids among the three age stages, but the essential amino acid index of the 2 year old was the highest (72.205), indicating that its essential amino acid composition was more suitable for human needs. For fatty acids composition, the content of monounsaturated fatty acids (2.759 mg/g) and polyunsaturated fatty acids (3.422 mg/g) of the 3 year old was significantly higher than that of the others (P < 0.05), and it also had relatively lowest atherogenicity index (0.419) and thrombogenicity index (0.179) and the highest hypocholesterolemic/hypercholesterolemic fatty acid ratio (2.404), indicating that its fatty acid composition was healthier and more beneficial to the prevention of human cardiovascular and cerebrovascular diseases. For minerals composition, the contents of iron, zinc, and copper increased with age, while the contents of selenium and manganese decreased with age, with the highest selenium content in the 1 year old (1.522 mg/kg). The chromium, arsenic, lead, and cadmium contents were all lower than the Chinese national standard. In conclusion, the nutritional composition of Arctic graylings variated with age and consumers could select suitable Arctic graylings based on their nutritional needs.
