Abstract

We report, for the first time, a detailed analysis of the complicated two-dimensional (2-D) nuclear magnetic resonance relaxation spectra of the xylem and phloem of carrots. By combining chemical extraction with different 2-D pulse sequences attempts are made to assign relaxation peaks to cell components, including compartmentalized water, pectins, starch, proteins and hemicelluloses. In a separate report, we use these assignments to interpret the effects of thermal and high-pressure processing (M. E. Furfaro, N. Marigheto, G. K. Moates, K. Cross, M. L. Parker, K. W. Waldron, B.
