Starch Granule Structure and Reactivity Characterization Using High Performance Size Exclusion Chromatography with Fluorescence Detection Grant uri icon



  • Starch, which represents the second greatest biomass on the planet, is utilized in many food and industrial applications because of its abundance, relative low cost, and properties. It exists in the form of semi-crystalline, water insoluble granules comprised of two polymers: amylose and amylopectin. End-use applications of starch depend on its physiochemical properties, which are determined by starch granule composition and molecular structure. A comprehensive understanding of starch structure and reactivity is key to maximizing starch utilization and application in food and industrial settings. The acquisition of an HPSEC system with fluorescence analysis capability will provide increased insight and interpretative power into the molecular structural elements of starch granules and starch based materials. This instrument will extend the research capability by providing a novel capability presently not available. Further, it is anticipated to stimulate multidisciplinary collaborations and cross-sharing of ideas between researchers of multiple colleges (Agricultural and Life Sciences; Natural Resources; Engineering; Science). The instrument will also enhance the ability to generate both preliminary and full-scale data necessary for the procurement of significant research funding, which will facilitate the expansion, competitiveness, and long-term stability of the associated research programs.
