Research Project: H1-NMR Characterization of Commercial Citrus Juices Project Number: 5325-41430-011-03
Project Type: General Cooperative Agreement

Start Date: Jul 01, 2012
End Date: Jun 30, 2013

(1) Establish baseline metabolic profiles of commercial citrus products through the use of H1-Nuclear Magnetic Resonance (NMR). (2) Determine the influence of cultivar variety, environment and plant health on the metabolite composition by comparing the profiles obtained for these samples to those obtained for other citrus products. (3) Ddentify diagnostically significant metabolites.

Citrus fruits harvested by a commercial source will be processed into juice and provided for analysis. Juice samples will be prepared for analysis by H1-NMR and analyzed. Initial data analysis and the subsequent statistical analysis will be conducted at the UC Davis in conjunction with the ARS Scientists at the Western Regional Research Center, Albany, CA. Additional samples for analysis may be obtained from commercial citrus growers or from citrus variety collections. It is expected that the total number of samples to analyze will range from 100 to 150 samples.
