1. 6. 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. 7. 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.

4. 8. 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

5. 9. Short-Chain Fatty Acid Starch Stabilized Pickering Emulsions : Design, Properties and Applications

   Författare :Nabilah Binti Abdul Hadi; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Short-chain fatty acid starch; Physicochemical properties; Pickering emulsions; Starch modification; Emulsion stability; Starch hydrolysis; In vitro digestion; Lipolysis;

   Sammanfattning : Pickering emulsions are emulsions stabilized by solid particles. Particles with optimal dual wettability toward both of the oil and water phases, can be adsorbed onto the interface, thereby providing the stability of the emulsions. LÄS MER

7. 10. Starch stabilized Pickering emulsions : Colloidal starch particles and their effects on emulsion properties

   Författare :Hisfazilah Saari; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :Starch granules; Pickering emulsions; colloidal particles; sedimentation; acid hydrolysis; cold gelatinization; dissolution; non-solvent precipitation; nanoparticles;

   Sammanfattning : Particles can be used to stabilize multi-phase systems known as Pickering emulsions. The aim of this thesis was to investigate how starch particles affect emulsion properties. Starch granules were used individually as well as in binary mixtures. LÄS MER
