New 1H NMR Procedure for the Characterization of Native and …
2011年5月24日 · A novel, fast, and straightforward procedure is presented for the characterization of starch (the largest energy component in food) and modified starches (such as octenyl succinic anhydride (OSA)-modified starches used as a dispersing agent in the food industry).
Starch NMR - ScienceDirect
2014年1月1日 · Nuclear magnetic resonance (NMR) spectroscopy is a major tool for the analysis of both chemical and physical properties of starches and starch-containing systems. At the molecular level, high-resolution NMR is the method of choice for defining the degree of branching of starch polysaccharides in solution.
1 H NMR spectra of (a) native starch and (b) cationic starch.
In the 1 H NMR spectrum of native starch (Fig. 4a), the signals at 3.3 and 2.5 ppm were assigned to hydrogen atom of the solvent DMSO. As expected, the peaks recorded between 4.5 and 5.5 ppm...
Solid-State NMR Spectroscopy: Towards Structural Insights into Starch …
This article aims to provide a comprehensive and critical review of research characterizing starch-based materials using solid-state NMR, and to briefly introduce the most advanced and promising NMR strategies and hardware designs used to overcome the sensitivity and resolution issues involved in structure–function relationships.
1H–13C NMR-Based Profiling of Biotechnological Starch …
2016年9月7日 · We show that considerable molecular detail of starch fragmentation can be obtained from multivariate analysis of spectral features in optimized 1 H– 13 C NMR spectroscopy of starch fragments to identify relevant features that distinguish processes in starch utilization.
