Debranched cassava starch crystallinity determination by Raman spectroscopy: Correlation of features in Raman spectra with X-ray diffraction and 13C CP/MAS NMR spectroscopy

► Analyzed starches of different crystallinities using X-ray diffraction and 13C CP/MAS NMR spectroscopy. ► Correlated calculated crystallinities with FT-Raman spectra. ► Strong linear correlation exists between crystallinity and integrated areas of Raman bands. ► FT-Raman spectroscopy is a promising tool for rapid determination of starch crystallinity.
