  3. 2. Supercritical Hydrogenation of Vegetable Oils

    Författare :Maj-Britt Macher; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium catalyst; supercritical; hydrogenation; silver ion HPLC; rapeseed oil; fatty acid methyl ester; trans fatty acid; palm oil; deactivation; propane;

    Sammanfattning : Vegetable oils were hydrogenated in a supercritical single-phase mixture with propane and hydrogen. The reaction was carried out in a small (0.5 ml) fixed-bed reactor and the influence of different process parameters was investigated. LÄS MER

  4. 3. Fatty Acid Desaturase Activities in Metabolic Syndrome and Cardiovascular Disease : Special Reference to Stearoyl-CoA-Desaturase and Biomarkers of Dietary Fat

    Författare :Eva Warensjö; Ulf Risérus; Bengt Vessby; Tommy Cederholm; David Laaksonen; Uppsala universitet; []
    Nyckelord :Nutrition; Fatty acids; Dietary fat; Biomarker; Metabolic Syndrome; Mortality; Obesity; Insulin Sensitivity; Epidemiology; Estimated desaturase activities; Stearoyl-CoA-desaturase; delta-6-desaturase; delta-5-desaturase; Single Nucleotide Polymorphism; Dietary Intervention; Rapeseed oil; Saturated fat; SCD1; Näringslära;

    Sammanfattning : The development of the metabolic syndrome (MetS) and cardiovascular diseases have been suggested to be influenced more by the quality than the amount of dietary fat. The FA composition of serum lipids may be used as biomarkers of dietary fat quality. LÄS MER

  5. 4. Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil

    Författare :Shahin Akhlaghi; Ulf W. Gedde; Jean-Luc Gardette; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradation; Acrylonitrile butadiene rubber; Fluoroelastomers; Biodiesel; Hydrotreated vegetable oil; Cavitation; Bound rubber; Dehydrofluorination.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. LÄS MER

  7. 5. Development of Lepidium campestre into a new oil and catch crop

    Författare :Emelie Ivarson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : A growing world population and dwindling fossil oil reserves demand an increase in the world plant oil production. The possibility to increase the area of cultivated land is limited due to the shortage of arable land. Also, the possibility for increasing the oil content in the limited number of cultivated oil crops is restricted. LÄS MER
