1. 1. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures

   Författare :José da Cruz Francisco; Kemiska institutionen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural oils; fats and waxes technology; Naturliga oljor; fetter; vax; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; phase behavior; soybean lecithin; monoolein; cineole; terpenes; eucalyptus; extraction; Essential oils; supercritical carbon dioxide;

   Sammanfattning : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. LÄS MER

5. 4. 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.

7. 5. Health Effects of Foods Enriched with Cereal beta-Glucans from Cereals

   Författare :Maria Biörklund; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Näringslära; Nutrition; glucose; cholesterol; oats; barley;

   Sammanfattning : Since soluble fibre in the form of the cereal beta-glucans found in oats and barley has been shown to have a positive effect on lipid and glucose metabolism, people at risk of developing cardiovascular diseases or diabetes might benefit from that a variety of palatable food products containing beta-glucans being available to them. The aim of the papers presented in the thesis was to evaluate the metabolic effects on persons with hypercholesterolemia or type 2 diabetes of various new food prototypes supplemented by beta-glucans.
