WebJul 15, 2024 · The FTIR spectra of starch may be used as an indication of surface structure of the granules. In a study on irradiated cowpea starch (Abu et al. 2006), the ratio of infra-red intensity (absorbance) at bands of 1042 cm −1 and 1024 cm −1 was considered as a measure of degree of order of starch granules at the surface. WebMar 17, 2024 · The esterification of starch with CA and hydrogen bond interaction among starch, fibers and CA were shown by the FTIR spectra. A good dispersion of 2.5–5 wt% TEFB fibers within the plasticized starch matrix and a good compatibility between starch and fibers induced by CA were evidenced by the SEM analysis. The melting temperature …
WebJul 13, 2024 · In the FTIR spectrum of starch, the band in the region of 920–938 cm −1 is derived from oscillations of α-1,4-glycosidic and α-1,6-glycosidic bonds. If the content of amylopectin is higher i.e. α-1,6-glycosidic bond, the characteristic band is shifted to a greater extent towards the higher wavenumbers [16, 30].
