Continued Screening of Amaranth Accessions for Variation in Starch Properties

Dr. Mark Campbell, Faculty Mentor

During the summer of 2003, we conducted a study at Truman State University with the long term objective of identifying amaranth accessions having unique thermal properties. Using a modified DSC method, Ejikemenwa Anih screened 220 amaranth ground grain samples for variation in DSC thermograms that may reflects variations in starch gelatinization temperature and amylose content and found a great deal of variation. However, we do not know for certain that this variation is due to actual differences in starch properties because these samples do not represent pure starch but instead ground grain. Therefore, our first objective for this subsequent study was to grow out the subset of accessions previously analyzed in order to obtain larger grain sample for further analysis of purified starch. A DSC analysis of these purified samples will help us determine if a correlation exists between these values and those obtained from the ground grain samples conducted last summer.
