Biological Evaluations, NMR Analyses, Molecular Modeling Studies, and Overview of the Synthesis of the Marine Natural Product (−)-Mucosin
Nolsøe, Jens Mortansson Jelstrup; Underhaug, Jarl; Sørskår, Åshild Moi; Antonsen, Simen; Malterud, Karl Egil; Gani, Osman; Fan, Qiong; Hjorth, Marit; Sæther, Thomas; Hansen, Trond Vidar; H. Stenstrøm, Yngve (Journal article; Peer reviewed, 2024)Natural products obtained from marine organisms continue to be a rich source of novel structural architecture and of importance in drug discovery, medicine, and health. However, the success of such endeavors depends on the ... -
Characterization of high value products in the side-stream of Laminaria hyperborea alginate production - Targeting the phenolic content
Wekre, Marie Emilie; Holmelid, Bjarte; Underhaug, Jarl; Pedersen, Bjørn; Kopplin, Georg; Jordheim, Monica (Journal article; Peer reviewed, 2023)Sustainable production based on renewable biomass and efficient bioprocesses are important elements in the growing blue bioeconomy. The traditional Laminaria hyperborea alginate production disposes approximately 80 % of ... -
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 ... -
An NMR study of α-lactalbumin pka-determinations and structural calculations
Underhaug, Jarl (Master thesis, 2004) -
Quantification of Polyphenols in Seaweeds: A Case Study of Ulva intestinalis
Wekre, Marie Emilie; Kåsin, Karoline; Underhaug, Jarl; Holmelid, Bjarte; Jordheim, Monica (Peer reviewed; Journal article, 2019-12-03)In this case study, we explored quantitative 1H NMR (qNMR), HPLC-DAD, and the Folin-Ciocalteu assay (TPC) as methods of quantifying the total phenolic content of a green macroalga, Ulva intestinalis, after optimized ... -
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 ... -
A Workup Protocol Combined with Direct Application of Quantitative Nuclear Magnetic Resonance Spectroscopy of Aqueous Samples from Large-Scale Steam Explosion of Biomass
Løhre, Camilla; Underhaug, Jarl; Brusletto, Rune; Barth, Tanja (Journal article; Peer reviewed, 2021)Methods for thermochemical conversion of biomass into renewable energy and materials rapidly increase in range and outreach. A focus on the target product streams for valorization is natural, yet several pretreatment steps ...
