1. 16. Potato Starch Dispersions: Structure and Rheology

   Författare :Karin Svegmark; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The influence of heating, shearing and addition of amylose on the structure and rheology of potato starch dispersions has been evaluated. The methods used were dynamic viscoelastic measurements, light microscopy and transmission electron microscopy (TEM). LÄS MER

3. 17. Exploring Selectivity and Hysteresis : Kinetic Studies on a Potato Epoxide Hydrolase

   Författare :Diana Lindberg; Mikael Widersten; Gunnar Johansson; Richard N. Armstrong; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; regioselectivity; selectivity; hysteresis; conformational changes; cooperativity; deep eutectic solvents; methylstyrene oxide; Biochemistry; Biokemi; Biokemi; Biochemistry;

   Sammanfattning : The kinetic mechanism of an α/β hydrolase fold epoxide hydrolase from potato, StEH1, has been studied with the aims of explaining the underlying causes for enantio- and regioselectivity, both being important for product purity. Further effort has been laid upon understanding the causes of a hysteretic behavior discovered in the measurements leading to Paper I. LÄS MER

5. 19. Defence and signalling in Potato-Phytophthora infestans interactions

   Författare :Ashfaq Ali; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytophthora infestans; Plant defence; hypersensitive response; resistance; susceptibility;

   Sammanfattning : Potato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. LÄS MER

7. 20. 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.
