Abstract:
The datasets presented in this article represent detailed NMR spectral analyses on red beet fiber, including the pomace, water-soluble and water-insoluble fractions, as well as the acid-extracted pectin. The samples were solvated in deuterium oxide and investigated by 1D-1H, 1D-13C NMR, and multiple 2D-NMR experiments, including gCOSY, zTOCSY, HSQC, HMBC, HSQCTOCSY, and H2BC. The NMR chemical shifts, coupling constants and spin-systems were identified for the major carbohydrate residues in each sample. This article provides additional data related to the research article "Structural characterization of red beet fiber and pectin" published in Food Hydrocolloids [1].
