Abstract Structured lipids are esters of fatty acids, which were modified from its natural form. The aim this work was to obtain structured by chemical interesterification the swine lard with bleached oil or carp viscera. materials and produced characterized physicochemical, differential scanning calorimetry (DSC), Fourier transform infrared (FT‐IR), nuclear magnetic resonance (NMR), solid fat content analysis be evaluated reaction. blends lard/fish presented similar characteristics lard....
The aim of this work was to study the bleaching oil extracted from heads catfish by thermomechanical process through equilibrium, kinetics, and thermodynamics adsorption studies. condition for step with 1% (w/w) adsorbent composed 95% activated earth 5% carbon (w/w). pseudo-first order pseudo-second models were most appropriate represent kinetics. temperature 80 °C increased capacity two adsorbates, activation energies values 47.47 44.82 kJ mol−1, respectively, carotenoids peroxides....
Chitosan nanocapsules containing polyunsaturated fatty acid (PUFA) concentrates from tuna oil, with EPA + DHA contents around 57% (w/w), were developed by emulsification process, using different chitosan concentration (1.0%, 1.5%, 2.0%, w/v) and stirring speed (10,000, 15,000, 20,000 rpm). The effects of these parameters on particle size zeta potential evaluated. physical oxidative stabilities used to measure the product quality during storage. concentration, its interaction significantly...
Abstract Waste from the fish processing industry can provide a profitable and sustainable business. Industrial by‐products be used as raw material to produce biofuels. This work evaluates production process, characterization, economic analysis for of biodiesel fishmeal tilapia waste. It demonstrates potential neutralized oil valuable production. presents specific mass, viscosity, flash point results in line with ASTM EN standards. Different plant sizes are modeled evaluate viability. Only...
Summary This work aimed at oil extraction from catfish ( Netuma barba ) heads through the CO 2 supercritical fluid (SFE‐CO ), and ranges of conditions were time (1 3 h), temperature (40 60 °C) pressure (15 25 MPA). The crude presented yield in thermomechanical was 86% compared to Bligh Dyer method, with concentrations eicosapentaenoic acid (EPA) docosahexaenoic DHA approximately 9.0% 11.9%, respectively, profiles after refining process. In extraction, highest around 84% MPa 40 °C h, lower...
The aim was to obtain structured lipids by chemical interesterification of saturated fat (lard) with bleached oils from fish heads (carp and tuna). All materials were characterized physicochemical analyses, gas chromatography for fatty acid profiles, nuclear magnetic resonance unsaturated acids esterified in sn-1,3 sn-2 positions the triacylglycerols, differential scanning calorimetry solid content (SFC). amounts eicosapentaenoic docosahexaenoic much higher tuna oil (32%), showing presence...
The current moment requires the development of new technologies that can provide alternatives to conventional treatment and efficiently remove pollutants are difficult treat. Activated carbon has been highlighted as low cost material be used adsorbents for removal contaminants. Thus, aim present study was analyse relevant literature related production activated water. For study, there were found 4,182 studies in database Web Science from these restrictions readings obtained 27 articles....
Este trabalho teve como objetivo extrair óleo bruto de cabeças bagre (Ictalarus puntatus) através do processo termomecânico produção farinha pescado, realizar o refino químico obtido e avaliar a qualidade dos óleos branqueado, das análises químicas acidez livre (AGL), índices peróxido (IP), iodo (II) saponificação (IS). As apresentaram teores (% m/m) umidade 69,90%, proteína 8,39%, lipídios 11,93% cinzas 9,78%. O apresentou AGL 6,62% em ácido oléico, IP 13,08 meq/kg, IS 189 mgKOH/g II 126...
– Este trabalho teve como objetivo avaliar as diferenças no comportamento térmicode lipídios estruturados obtidos mediante a interesterificação de banha suína comóleo e ésteres pescado. Os foram através da interesterificaçãoquímica blendas contendo suína:óleo pescado banhasuína: pescado, sendo variadas quantidade catalisador proporção dasblendas. A partir dos resultados foi possível determinar que apenas proporçõesdas (80:20 70:30) apresentaram influências significativas defusão composição...
