Comparison of dietary phospholipids and neutral lipids on skeletal development and fatty acid composition in Atlantic cod (Gadus morhua) ArchiMer
Kjorsvik, Elin; Olsen, Cecilia; Wold, Per-arvid; Hoehne-reitan, Katja; Cahu, Chantal; Rainuzzo, Jose; Olsen, Atle Ivar; Oie, Gunvor; Olsen, Yngvar.
Dietary essential fatty acids may affect larval skeletal formation. The aim of this study was to compare effects on growth and osteological development of dietary docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) being incorporated in the phospholipid (diets PL1 and PL3) or in the neutral lipid (diet NL1) fraction of the larval diet for Atlantic cod (Gadus morhua). The diets were labelled according to the estimated percentage of total n-3 fatty acids contained in the dietary neutral lipid (NL1-1.3% of dietary dry matter) or in the phospholipid fraction (PL1-1.1% and PL3-2.3%). Larvae were weaned to the isoenergetic and isolipiclic microdiets from 17 days post hatching (dph). They were co-fed enriched rotifers until 24 dph and received thereafter...

Composition of omega-3 and omega-6 fatty acids in freeze-dried chicken embryo eggs with different days of development BABT
Campos,Célia Maria Teixeira de; Hamad,Antônio José Simões; Block,Jane Mara; Padilha,José Carlos Fiad; Ogliari,Paulo José; Barreira-Arellano,Daniel; Moreira,Rosana Nogueira Cavalcanti.
Fatty acids omega--3 and omega--6 composition and specially DHA were determined in freeze-dried chicken embryo eggs with pre-determined incubation periods. Fertile and embryo eggs presented palmitic (23.18 + 0.54%), stearic (7.70 + 0.28%), palmitoleic (3.00 + 0.19%), oleic (36.28 + 0.58%), linoleic (22.18 + 0.34%), linolenic (1.08 + 0.04%), arachidonic (2.04 + 0.03%), docosahexaenoic (0.91 + 0.03%), total omega-3 acids (2.26 + 0.10%) and total omega-6 acids (24.62 + 0.33%). There were no significant differences in total contents of omega-3 fatty acids (p=0.1226) between freeze-dried chicken embryo eggs with different incubation periods (3, 5, 7, 9, and 11 days) and fertile freeze-dried chicken eggs (day 0). However, there were significant differences in...

Concentração de ácido eicosapentaenóico (EPA) e ácido docosahexaenóico (DHA) em peixes marinhos da costa brasileira Ciênc. Tecnol. Aliment.
VISENTAINER,Jesuí Vergilio; CARVALHO,Patrícia de Oliveira; IKEGAKI,Masaharu; PARK,Yong Kum.
Análises experimentais foram realizadas objetivando a composição quantitativa dos ácidos graxos Eicosapentaenóico (EPA) e Docosahexaenóico (DHA), em diferentes partes do corpo de espécies de peixes marinhos da costa brasileira (atum, bonito, olho de boi, cavalinha, sardinha e serra). Os teores de EPA e DHA foram analisados em duas partes distintas: olho (órbita ocular e material gorduroso da cavidade ocular) e filés, sendo significativas as diferenças entre as mesmas. Os teores de DHA para uma determinada espécie foram sempre superiores no olho em relação ao filé, sendo o mesmo observado para o EPA em quatro das espécies (olho de boi, cavalinha, sardinha e serra). Comparando-se a mesma espécie e partes do corpo dos peixes, observou-se que os teores de DHA...

Effect of malate on docosahexaenoic acid production from Schizochytrium sp. B4D1 Electron. J. Biotechnol.
Zhanga,Yong; Min,Qingsong; Xu,Jian; Zhang,Ke; Chen,Shulin; Wang,Haijun; Li,Demao.
Background: Malate involves in the citrate/malate and transhydrogenase cycles to provide precursors for docosahexaenoic acid (DHA) synthesis. The optimal strategy was investigated for increasing DHA production in Schizochytrium species during fermentation. Results: DHA production increased by 47% and reached 5.51 g/L when 4 g malate/L was added during the rapid lipid accumulation stage in shake-flasks culture. Inducing effects of malate was further investigated through the analysis of three kinetic parameters, including specificcell growth rate(μ), specific glucose consumption rate (qGlu)and DHA formation rate (qDHA). DHA concentration was enhanced through a novel fed-batch strategy to a maximum value of 30.7 g/L, giving a yield of 0.103 g DHA/g...

Effect of spray drying on the fatty acids content and nutritional indices of buffalo powdered milk Ciênc. Tecnol. Aliment.
ALVES,Mariana Ferreira; BORGES,Marília Viana; FLORÊNCIO FILHO,Daniel; CHAVES,Modesto Antônio; LANNA,Dante Pazzanese; PEDREIRA,Márcio dos Santos; FERRÃO,Sibelli Passini Barbosa; FERNANDES,Sérgio Augusto de Albuquerque.
Abstract The buffalo’s reproductive seasonality determines the decrease in milk and cheese production generating economic losses on the production system. Among various food process, we find the spray-dryer as an essential tool which helps food conservation. We achieved the milk powder in three replicates and each repetition processed 10 L of buffalo milk. After obtaining the final product, three samples (200 g) were packaged for each evaluated storage time (0, 30, 60, 90, 120 and 150 days at room temperature). In this context, we assessed the effects of drying buffalo’s milk by atomization (spray dryer) and storage time effects on the milk fat. We observed that the spray drying did not alter the fatty acid content and nutritional indices evaluated, except...

Hidrólise enzimática do óleo de pescado Ciênc. Tecnol. Aliment.
Padilha,Márcia Elisa da Silva; Augusto-Ruiz,Walter.
O óleo de pescado tem sido alvo de várias pesquisas em função dos benefícios nutricionais dos ácidos graxos poliinsaturados. Esse fato pode ser comprovado pelos estudos epidemiológicos que relacionam a baixa incidência de doenças cardiovasculares com o consumo de ácidos graxos n-3 (EPA-eicosapentaenóico e DHA-docosahexaenóico) provenientes de peixes marinhos. A obtenção de ácidos graxos poliinsaturados n-3 pode ser realizada por hidrólise enzimática. A hidrólise enzimática de óleos e gorduras, ou lipólise, é bem conhecida e vem sendo estudada para produzir ácidos graxos e modificar as gorduras por esterificação, transesterificação e interesterificação. O objetivo deste trabalho foi a obtenção de ácidos graxos poliinsaturados por hidrólise enzimática do...

Lipid composition of the giant lion's-paw scallop (Nodipecten subnodosus) in relation to gametogenesis - I. Fatty acids ArchiMer
Palacios, Elena; Racotta, I; Kraffe, E; Marty, Y; Moal, Jeanne; Samain, Jean-francois.
Seasonal variations in fatty acid composition in several tissues of a 1-year-old population of giant lion's-paw scallop Nodipecten subnodosus were analyzed during gonad development. Samples were taken bimonthly from December 1999 to June 2000, a period in which gonad development was occurring. Fatty acid accumulation in neutral and polar lipids of the female gonad was concomitant to the gonad development and presented a maximum in June. Among essential fatty acids, a specific accumulation was observed only for 20:5n - 3 in the female gonad, as suggested by an increase in its proportion in the neutral and the polar fractions. However, no specific accumulation was observed for 22:6n - 3, as its proportion remained relatively constant in both fractions. We...

Lipid composition of the liver oil of the ray, Himantura bleekeri ArchiMer
Le Nechet, Sandrine; Dubois, Nolwenn; Gouygou, Jean-paul; Berge, Jean-pascal.
If rays are traditionally fished for their caudal fins, the rest of the body is wasted, except part of the skin that can be transformed into leather. Liver oil of the ray, Himantura bleekeri, was characterized in terms of lipid class composition and fatty acid profile. Liver oil content was high and represented 54% of the liver weight (w/w). Neutral lipids were predominant (92%), major components being triacylglycerols (63%). Other neutral lipids identified were hydrocarbons, sterol esters, mono- and di-acylglycerols, free fatty acids, sterols and glyceryl ethers. Polyunsaturated fatty acids of the n-3 series, namely eicosapentaenoic and docosahexaenoic acids, were high (4% and 16%, respectively). Cholesterol was the major component in the sterol fractions...

Natural antioxidants in the stability of ray liver oil Ciência Rural
Navarro-García,Gerardo; Gámez-Meza,Nohemí; Medina-Juárez,Luis Angel; Ortega-García,Jesús; Cota-Quiñones,Elizabeth; Ramirez-Suarez,Juan Carlos.
ABSTRACT: The effect of the addition of natural antioxidants on oxidative stability of ray ( Rhinoptera bonasus) liver oil was evaluated. Different concentrations of rosemary extract, α-tocopherol, and caffeic acid (w/w) were added to the oil. Afterwards, concentration of each antioxidant that gave the highest stability was used in an accelerated stability test (Schaal method). The protective effect was established by the retention in the oil of fatty acids eicosapentaenoic (EPA) and docosahexaenoic (DHA), and concentration of volatile compounds. The best concentrations were: 2.5% of rosemary extract, 0.5% of α-tocopherol, and 0.06% of caffeic acid. Rosemary extract showed to be the product with the greatest ability to retard oxidation, followed by...
