WebFourier-Transform Infrared Spectroscopy (FTIR) associated with multivariate analysis enabled a structural comparison among the pectin extracts, and differential scanning calorimetry (DSC) completed a full landscape of the investigated extracts. Pectin extracts obtained by CHE showed mostly higher GalA than those obtained by TS. WebComparing the FTIR spectra of pectin 1 with sulfated pectins 2, one can see several differences. Aside from the large band at 1215 cm −1, which stems from the sulfate group (v (S=O)), the bands at 1422 and 1672 cm −1 (v (C=O) from carboxylate) were also markedly more pronounced in 2. The reason for this is most likely a hydrolysis of the ...

WebJan 23, 2024 · Based on FTIR spectral analysis, the results indicated that the bands of the functional groups of the extractive from the original bark remain unchanged; however, the absorbance intensity was found to be weaker in the group frequency and fingerprint regions. Removal of extractive, pectin, hemicellulose and lignin from the bark indirectly ... WebApr 14, 2024 · FTIR analysis confirmed the interaction of the host polymer–dopant salt (K 3 PO 4) complex with the plasticizer (glycerol) via band shifting and the alteration of peak intensities. Furthermore, XRD studies confirmed that the incorporation of glycerol greatly improved the amorphous properties of the SBEs, thereby improving ionic conductivity. solatecs w 800
Physicochemical Characterization and FTIR Spectroscopic Study of Pectin …
WebFourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) showed that the interaction between SPI and pectin was enhanced and the crystallinity of the emulsion gels was changed due to the HIU treatment. Confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM) observations revealed that the particle size ... WebDec 3, 2024 · Pectin is widely used both in food sector (as gelling, thickening, and stabilizer agent) and in pharmaceutical industries (bioactive components) including biomedical application (drug delivery, tissue … WebMay 1, 2016 · In this work, a pectin isolated from citrus peel with a degree of esterification of 76% was characterized by FTIR and FT-Raman spectroscopies. The polygalacturonic acid chain was studied taking into account their partial esterification’s degree by simulation of two different subunits, one with both COOH and COO CH 3 groups ( Ac ) and, the ... solat hajat in english
