1. 1. The Challenges of Analyzing the Molecular Properties of Starch

   Författare :Daysi Pérez; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amaranthus caudatus; Chenopodium quinoa; Chenopodium pallidicaule; Canna indica; Lepidium meyenii; Xanthosoma sagittifolium; Manihot esculenta; starch; amylose; amylopectin; field-flow fractionation; size distribution; dissolution;

   Sammanfattning : Both the nutritional and functional properties of starch are directly influenced by the molecular structure of its polymers: amylose and amylopectin. It is therefore important to have reproducible methods for quantifying the molecular size. LÄS MER

3. 2. Molecular interactions between quinoa, the biocontrol agent Trichoderma and the pathogen Peronospora variabilis

   Författare :Oscar Miguel Rollano Penaloza; Molekylär cellbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; Molecular interactions; qRT-PCR; RNA-seq; Plant growth promotion; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; RNA-seq; qRT-PCR; molekylära interaktioner;

   Sammanfattning : Plants have developed complex molecular mechanisms to recognize and respond to the different microorganisms present in their surroundings. The most studied response mechanisms are plant defense responses. These defense response mechanisms share many similar components with the plant response mechanisms to beneficial microbes. LÄS MER

4. 3. Utilization of Andean grain flours in the development of wheat flour dough

   Författare :Sander Jonathan Pérez Villarroel; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :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;

   Sammanfattning : 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.

5. 4. Antioxidants in Andean food and meals

   Författare :Leslie Tejeda; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antioxidant capacity; polyphenolic compounds; anthocyanidins; individual food; meals; ans and stan genes;

   Sammanfattning : Abstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethylbenzotiazoline-6-sulfonic acid) and FRAP (ferric reduction antioxidant power), were used to evaluate antioxidant activity. LÄS MER

7. 5. Biologically active terpenoids from Bolivian medicinal plants

   Författare :Maribel Lozano Palacios; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bolivian plants; cytotoxicity; triterpenes; damsin; breast cancer;

   Sammanfattning : Pseudo-guaianolides represent a large group of sesquiterpene lactones exhibiting significant cytotoxic and anti-inflammatory activities. Their biological activities are due to a 훼-methylene-훾-lactone unit in their chemical structure, which reacts with free sulfhydryl groups of free cysteine via a Michael-addition. LÄS MER
