6. New Approaches to Investigate and Prevent Oxidation of Polypropylene
Sammanfattning : When employing chemiluminescence to evaluate stabiliserperformance in a polymer, the induction time or the time toreach maximum chemiluminescence intensity is often used. Insuch an experiment the longest part of the experiment isnormally the time before the oxidation starts. LÄS MER
7. Effect of Dietary Antioxidants on Oxidative Stress, Inflammation and Metabolic Factors : Studies in Subjects with Overweight and with Type 2 Diabetes
Sammanfattning : Observational studies have indicated that fruit and vegetables, and dietary antioxidants may play an important role in reducing the risk of chronic diseases, potentially by affecting pathogenic mechanisms such as oxidative stress and inflammation. Clinical trials investigating the effects of supplementation with single or a few antioxidants in high doses have, however, shown inconsistent results and thus have not been able to support the observational findings.

8. Antioxidant-Impregnated Polymers / Antioxidant Ability and Interactions with Food
Sammanfattning : Interactions between antioxidant-impregnated low-density polyethylene (LDPE) and polypropylene (PP), and oxygen-sensitive foods have been investigated. BHT and a-tocopherol are two antioxidants commonly used in both foods and polymers. In general, BHT was rapidly lost from LDPE film in contact with various foodstuffs. LÄS MER
9. Chromatography and extraction techniques for new evaluation methods of polyolefins long-term performance
Sammanfattning : Chromatography and extraction techniques, and also chemiluminescence have been utilized to develop new rapid and informative tools in the evaluation of long-term properties and environmental effects of polymeric materials. Methods were developed for classification of materials and for early and rapid degradation detection. LÄS MER
10. Antioxidative Properties of Herring (Clupea harengus) Press Juice in Food, In Vitro and In Vivo Model Systems
Sammanfattning : Some species like herring (Clupea harengus) are currently under-utilized due to their small size, dark colour and susceptibility to lipid oxidation. Our hypothesis has been that the high susceptibility of herring to oxidation makes it well equipped with natural antioxidants, both fat and water soluble ones. LÄS MER
