Effects of antioxidants on copper induced lipid oxidation during salting of cod (Gadus morhua L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2003-12-02)
A model system for studying lipid oxidation of salted cod muscle was used for investigating the interaction effects of including antioxidants and copper in the brine. The results showed that ascorbate might have pro-oxidative or anti-oxidative effects depending on the ascorbate and metal concentrations. Without added copper in the brine, concentrations of ascorbate ≤500 ppm had a pro-oxidative effect. ...
Induction of tetraploid gynogenesis in the European sea bass, Dicentrarchus labrax L.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2003)
A preliminary study on tetraploid gynogenetic induction in the European sea bass was performed by pressure-blocking the second polar body release and the first cleavage in eggs fertilized with ultraviolet-irradiated sperm. Fertilization of eggs with genetically inactivated sperm produced only haploid development that terminated around hatching. Pressure treatments (8.500 psi for 2 min) applied at 6 ...
