  2. 1. Utilization of Andean grain flours in the development of wheat flour dough

    Author : Sander Jonathan Pérez Villarroel; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wheat; Andean grains; Amaranth; Amaranthus caudatus; Canahua; Chenopodium pallidicaule; Quinoa; Chenopodium quinoa; Dough; Substitution; Ultracentrifugation; Phase separation; Dough composition; Macroscopic separation; Freezable water; Textural properties; Compression; Uniaxial tension; Biaxial tension; Principal component analysis; Partial least square regression; Bread;

    Abstract : Bread dough was studied in relation to three Andean grain flours, quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and canahua (Chenopodium pallidicaule), as partial replacements for wheat flour with the perspectives of dough and breadmaking. This thesis deals with the understanding of both dough as a complex system, consisting of various water-filled polymers, and dough as a viscoelastic material, with different responses to deformations, in order to contribute to possibilities for improvements in dough analysis and development of novel products.

  4. 2. Fermented probiotic beverage based on quinoa : Functionality, hygiene, and health effects

    Author : Pamela Rosario Canaviri Paz; Avdelningen för livsmedel och läkemedel; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quinoa grains; Fermentation; Lactic acid bacteria; Probiotics; Food safety; Starter culture; Polyphenol compounds; Microbiota composition; Functional food; Gut microbiota;

    Abstract : White quinoa grains were used as a source of novel beneficial microorganisms and as a matrix for development of a fermented plant-based drink. Studies on the quinoa grain microbiota were performed by applying spontaneous fermentation to allow isolation of autochthonous Lactiplantibacillus strains with potential to be used as starter cultures.

  5. 3. 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

  6. 4. Milk Membrane Lipids - Dispersions, Emulsions and Interactions with Proteins

    Author : Rianne Waninge; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Model milk membrane lipids; Emulsions; Vesicles; Cryo-TEM; Milk fat globule membrane; MFGM; Livsmedelsteknik;

    Abstract : Milk is a dilute aqueous dispersion with a complex mixture of proteins, fat, carbohydrates, vitamins and minerals. Milk membrane lipids are a part of the milk fat globule membrane (MFGM), which covers the fat globules. During dairy processing membrane material is released and surface structure features are altered. READ MORE

  7. 5. Rapid sample preparation and bioanalytical techniques for efficient screening of organic pollutants in the environment

    Author : Malin Nording; Peter Haglund; Ron Hoogenboom; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accelerated solvent extraction; CAFLUX; food; immunoassay; PAH; PCDD; PCDF; pressurized liquid extraction; soil; CALUX; cell-based bioassay; chemically activated fluorescent gene expression; chemically activated luciferase gene expression; dioxin; ELISA; enzyme-linked immunosorbent assay; feed; Environmental chemistry; Miljökemi;

    Abstract : Large numbers of samples often need to be prepared and analysed in surveys of organic pollutants in the environment, but while the methods commonly used in such surveys can provide abundant detail they are generally costly, time-consuming and require large amounts of resources, so there is a need for simpler techniques. The work underlying this thesis assessed the potential utility of more convenient sample preparation and bioanalytical techniques for rapidly screening various environmental matrices that could be useful complements to higher resolution methods.
