3. 2. Glutathione peroxidase and selenium in meat - Tissue and species variation, thermal stability and selenium speciation

   Författare :Charlotte Daun; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nutrition; Näringslära; speciation of selenium; lipid oxidation; thermal stability; RN phenotype; ageing; meat; Glutathione peroxidase; selenium;

   Sammanfattning : Lipid oxidation is a major problem in muscle foods, leading to a loss in quality and nutritional value. It occurs in raw meat but is usually more pronounced in cooked meat. Since the demands of consumers for ready-to-eat foods have increased, the control of off-flavour in cooked meat is an important industrial problem. LÄS MER

4. 3. Near field immobilization of selenium oxyanions

   Författare :Anders Puranen; Mats Jonsson; Christophe Jegou; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Se-79; Selenium; Immobilization; Redox; Iron; Corrosion; Palladium; Catalyst; Spent Nuclear Fuel; Repository; Nuclear chemistry; Kärnkemi;

   Sammanfattning : The topic of this doctoral thesis is the potential near field immobilization of the radionuclide 79Se after intrusion of groundwater into a spent nuclear fuel canister in a repository. 79Se is a non naturally occurring long lived selenium isotope formed as a result of fission in nuclear fuel.

7. 5. Selenium Compounds and Antioxidant Capacity in Bovine Milk. Studies on Glutathione Peroxidase, Bioavailability and Electrochemical Techniques

   Författare :Jun Chen; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; amperometry; voltammetry; antioxidant capacity; ileostomy; bioavailability; glutathione peroxidase; bovine milk; selenium;

   Sammanfattning : The efficacy and function of antioxidants have been intensively studied in foods and other biological systems in recent decades. This thesis concerns different aspects of the antioxidant properties of bovine milk, with emphasis on measurement of the total antioxidant capacity (TAC), the activity of the selenium-containing glutathione peroxidase (GSHPx), and the bioavailability of selenium from bovine milk in humans.
