2010 Annual Report 1a.Objectives (from AD-416) The overall research project has three objectives:. 1)characterize the interactions of arabinoxylan fiber, phenolics, and antioxidants during processing,. 2)develop analytical methods for phenolics and antioxidants, and. 3)determine the physico-chemical characteristics of bioactive compounds (arabinoxylans, phenolics, and antioxidants) during processing. Objective 2 will be conducted at the Food Composition Methods Development Laboratory (FCMDL). 1b.Approach (from AD-416) Samples provided by USDA-ARS Western Wheat Quality Laboratory will be initially used for optimization of sample preparation procedures for extraction of phenolic phytochemicals from wheat samples. Different cultivars of wheat samples will be used to collect spectral fingerprints and determine whether spectral fingerprinting methods can be used to differentiate wheat samples based on cultivar or other phytochemical traits. 3.Progress Report FCMDL is a co-PI on this 4 year grant awarded by AFRI to the Western Wheat Quality Lab and Washington State University. This agreement is new to FCMDL therefore there is no progress to report at this time. This agreement was monitored through routine conversations and emails with collaborators at the ARS Western Wheat Quality Lab and Washington State University.
