  1. 6. Novel potato starch : new structure and beneficial qualities

    Författare :Xue Zhao; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis presents a simplified method for determining the internal molecular structure of whole starch without prior amylopectin isolation. The structure of potato and barley whole starches, the thermal properties of starch from potato lines with different genetic backgrounds and the relationship between molecular structure and functional properties of starch were examined in the thesis.

  3. 7. Interactions between Amylose, Native Potato, Hydrophobically Modified Potato and High Amylopectin Potato Starches

    Författare :Fernando Ortega-Ojeda; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DSC; rheology; starch; polymers;

    Sammanfattning : The behaviour of different starches and their mixtures was investigated using several analysis techniques, i.e. small-deformation oscillatory measurements (rheological measurements), differential scanning calo-rimetry (DSC), light microscopy, and UV spectrophotometry (turbidi-metry).

  4. 8. On the two forms of amylose-lipid complexes

    Författare :Fredrik Tufvesson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bread; enzymatic hydrolysis; resistant starch; digestibility; fatty acid; monoglyceride; polar lipid; differential scanning calorimetry; annealing; amylose-lipid complex; crystallization; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik;

    Sammanfattning : This thesis is about the formation of amylose-lipid complexes, and their properties. Two forms of superstructures can be identified. Complex form I has more randomly distributed helices, while the structure of form II is crystalline and therefore exhibits the typical V-pattern in X-ray diffraction analyses. LÄS MER

  5. 9. Disturbance of Pb, Sr, and Nd isotope systems related to medium and low grade metamorphism illustrated with data from the polymetamorphic Early Proterozoic (Rombak) - Sjangeli basement window of the Caledonides of Northern Sweden

    Författare :Rolf Romer; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : The Sjangeli supracrustal belt forms the easternmost belt of a series approximately N-S striking, steeply dipping Early Proterozoic belts of the Rombak-Sjangeli basement window, which formed in an island arc setting. The volcanic units of the Sjangeli area consist of metatuffs, which contain abundant Cu-mineralizations, metalava flows and pillowed metalavas and are intercalated with banded carbonatesilicate rocks and micaschists, which contain various amounts of volcanic material.

  7. 10. Enhancing Composite Cassava Bread Quality - Effect of cassava pre-treatment and baking improvers

    Författare :Maria Eduardo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; baking improvers; bread quality; cassava flour; pre-treatment; composite bread; sensory evaluation;

    Sammanfattning : Due to unfavourable climatic conditions, the production of wheat in Mozambique is not sufficient to satisfy national food industrial needs and substantial quantities must be imported at high cost. Bread is currently produced basically using wheat flour. LÄS MER
