Cod protein powder lowered serum nonesterified fatty acids and increased total bile acid concentrations in healthy, lean, physically active adults: A randomized double-blind study
Vildmyren, Iselin; Halstensen, Alfred; Oterhals, Åge; Gudbrandsen, Oddrun Anita (Peer reviewed; Journal article, 2019-03-11)Background: Fish fillet consumption is associated with beneficial health effects; however, little is known about whether consuming other parts of the fish such as head, backbone, skin, cut-offs, and entrails (collectively ... -
Cod Residual Protein Prevented Blood Pressure Increase in Zucker fa/fa Rats, Possibly by Inhibiting Activities of Angiotensin-Converting Enzyme and Renin
Vildmyren, Iselin Thowsen; Drotningsvik, Aslaug; Oterhals, Åge; Ween, Ola; Halstensen, Alfred; Gudbrandsen, Oddrun Anita (Peer reviewed; Journal article, 2018-11-22)Hypertension is the leading risk factor for cardiovascular disease, and prevention of high blood pressure through diet and lifestyle should be a preferred approach. High intake of fish is associated with lower blood pressure, ... -
Daily intake of protein from cod residual material lowers serum concentrations of nonesterified fatty acids in overweight healthy adults: A randomized double-blind pilot study
Vildmyren, Iselin Thowsen; Cao, Huy John Vu; Haug, Lina Bowitz; Valand, Ida Ulrikke; Eng, Øyvin Andre Solberg; Oterhals, Åge; Austgulen, Maren Hoff; Halstensen, Alfred; Mellgren, Gunnar; Gudbrandsen, Oddrun Anita (Peer reviewed; Journal article, 2018-06-05)Improved process technologies have allowed fishing vessels to utilize residuals from cod fillet production (head, backbone, skin, cuttings, and entrails) and convert this to high-quality protein powders for human consumption. ... -
Decontamination of persistent organic pollutants in fishmeal and fish oil. Process optimization and modeling
Oterhals, Åge (Doctoral thesis, 2011-10-07)Persistent organic pollutants (POPs) are fat soluble chemical substances that persist in the environment and bioaccumulate in the food chain. Through long-range environmental transportation by air, water and migratory ... -
Effect of cod residual protein supplementation on markers of glucose regulation in lean adults: A randomized double-blind study
Vildmyren, Iselin; Halstensen, Alfred; McCann, Adrian; Midttun, Øivind; Ueland, Per Magne; Oterhals, Åge; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2020)Large quantities of protein-rich cod residuals, which are currently discarded, could be utilized for human consumption. Although fish fillet intake is related to beneficial health effects, little is known about the potential ... -
Effects of intact and hydrolysed blue whiting proteins on blood pressure and markers of kidney function in obese Zucker fa/fa rats
Drotningsvik, Aslaug; Oterhals, Åge; Mjøs, Svein Are; Vikøren, Linn Anja Slåke; Flesland, Ola; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2021)Purpose To investigate the effects of diets containing intact or hydrolysed proteins from blue whiting (Micromesistius poutassou) on the development of high blood pressure and markers of kidney function in obese Zucker ... -
Emulsion and Surface-Active Properties of Fish Solubles Based on Direct Extraction and after Hydrolysis of Atlantic Cod and Atlantic Salmon Backbones
Steinsholm, Silje; Oterhals, Åge; Underhaug, Jarl; Aspevik, Tone (Journal article; Peer reviewed, 2021)The focus on natural foods and “clean” labeled products is increasing and encourages development of new biobased ingredients. Fish solubles derived from downstream processing of side stream materials in the fish filleting ... -
Impact of fish protein concentrate on apparent viscosity and physical properties of soy protein concentrate subjected to thermomechanical treatment
Ahmad, Rafiq; Oterhals, Åge; Xue, Ying; Skodvin, Tore; Samuelsen, Tor Andreas (Peer reviewed; Journal article, 2019-04-30)The aim of this research was to investigate the plasticizing and binding effect of fish protein concentrate (FPC) on soy protein concentrate (SPC) with the use of a capillary rheometer with pre-shearing capabilities. A ... -
Molecular Dynamics Study of Selective Adsorption of PCB on Activated Carbon
Jensen, Bjørnar; Kuznetsova, Tatiana; Kvamme, Bjørn; Oterhals, Åge (2011)The selectivity of PCB adsorption from fish oil onto activated carbon (AC) was investigated by means of molecular dynamics to determine the importance of molecular planarity. PCB congeners 77 and 118 were selected for ... -
Reduction in flavor-intense components in fish protein hydrolysates by membrane filtration
Steinsholm, Silje; Oterhals, Åge; Thoresen, Lars; Underhaug, Jarl; Kousoulaki, Katerina; Aspevik, Tone (Journal article; Peer reviewed, 2021)Enzymatic protein hydrolysates based on side stream materials from the fish-filleting industry are increasingly explored as food ingredients. However, intense sensory properties, and high salt contents, are often a limiting ... -
Water-soluble fish protein intake led to lower serum and liver cholesterol concentrations in obese zucker fa/fa rats
Drotningsvik, Aslaug; Vikøren, Linn Anja Slåke; Mjøs, Svein Are; Oterhals, Åge; Pampanin, Daniela Maria; Flesland, Ola; Gudbrandsen, Oddrun Anita (Peer reviewed; Journal article, 2018-05-01)Proteins from different fish species and different raw materials such as fish fillets and by-products have shown promising cardioprotective effects in rodents and humans, including effects on cholesterol metabolism.
