Room temperature, low-field 13C-n.m.r. spectra of degraded kappa/iota carrageenans

Using samples previously degraded by autohydrolysis, it is possible to obtain valuable low-field 13C-n.m.r. spectra of samples of kappa/iota carrageenans at room temperature. Spectroscopy of samples extracted at different stages of autohydrolysis helps to determine the mechanism of the reaction and...

Sumario:Using samples previously degraded by autohydrolysis, it is possible to obtain valuable low-field 13C-n.m.r. spectra of samples of kappa/iota carrageenans at room temperature. Spectroscopy of samples extracted at different stages of autohydrolysis helps to determine the mechanism of the reaction and the presence of low proportion kinks and other irregularities in the molecules. © 1991.
