    • Fettsyresammensetning og kvalitetsaspekter og kommersielle krilloljeprodukter 

      Vu, Kim Anh Thi (Master thesis; Mastergradsoppgave, 2012-06)
      Krill er rik på omega-3 fettsyrene EPA og DHA, noe som forklarer den store kommersielle interesse for fangst og foredling av krill. I krillolje er det mye fosfolipider sammenliknet med fiskeoljer. Flere hevder at EPA og DHA utnyttes bedre når de er bundet i fosfolipider enn når de fins i triacylglyserol (Bunea et al, 2004; Werner, Havinga et al, 2004). Det er gjort lite forskning på krillolje og ...
