  1. 1. Development of Methods for Determination of Fat and Trace Constituents in Food, with Emphasis on Supercritical Fluid Extraction

    Author : Hans Berg; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supercritical fluid extraction; Steroids; SFE; Sample preparation; Meat; Lipid classes; Food; Fatty acid composition; Fat content; 3-butanediol; 2; Diacetyl; Acetoin; Androstenone; vitamins A and E.; Analytical chemistry; Analytisk kemi;

    Abstract : Sample preparation is the most time-consuming step in an analysis. Traditional sample preparation techniques consume large amounts of organic solvents, are time-consuming and are difficult to automate. READ MORE

  2. 2. Methods to study the relationship between forage composition and silage fermentation and aerobic stability

    Author : Kamyar Mogodiniyai Kasmaei; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis is based on the following hypotheses: (I) under controlled ensiling conditions, forage chemical and microbial composition explain variation in silage end-product concentrations (II) sterilized forage inoculated with parent microflora gives similar fermentation result as untreated control forage and (III) this methodology enables studying interactions between forage source and field flora on silage fermentation and aerobic stability. Hypothesis (I) was evaluated by constructing regression models of end-products on common forage chemical variables (e. READ MORE

  3. 3. Versatile Association Behavior in Mixtures of Oppositely Charged Amphiphiles : From DNA-Like Assembly of Supramolecular Helices to Coacervation in Chiral Surfactant Systems
