Abstract
Starch is the major component in oat endosperm, and its importance to the properties of products containing oat also is recognized. Although some work has been done on oat starches, little information has focused on starch structure and properties and the effects of lipids on structure and properties. The objectives of this study were to characterize the structure and physicochemical properties of oat starches with different lipid contents and to study the relations between the structure and functional properties. This thesis consists of three papers. The first paper studies structure and physicochemical properties of oat starches from groats with different lipid contents, the second paper focuses on the structure and properties of amylose, amylopectin and intermediate materials of oat starches, and the third paper investigates the functional properties of oat starches and relations among structures and properties of starch granules and starch fractions. The three papers follow the format of the Cereal Chemistry Journal.
