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 ...
WebThe interactions and specific micromorphology of films were also analyzed using FTIR and scanning electron microscope. The results showed that Fe 3+ and Cu 2+ could be uniformly distributed on the film surface and diffused into the interior by external in situ cross-linking. ... And the water resistance of the composite pectin films was ... WebAfter the hydrolization of pectin bypectinase, the reaction products were identified by FTIR and TLC analysis. First, according to characteristic C-O and C-C stretching vibrations of metabolites, the released sugars were determined by FTIR analysis. FTIR analysis was performed by using Thermo Scientific Nicolet iS10 FTIR Spectrometer.
WebFTIR spectroscopy has become an attractive alternative to traditional analytical methods due to the small amount of sample needed, the simple preparation that does not require hazardous solvents, and the rapidity and reproducibility of the analyses. ... and it is ascribable to C=O stretching in pectin methylesters. [Citation 25] WebOct 15, 2013 · Keeping all other reaction conditions constant, greater aldehyde contents were obtained in water-ethanol system than in pure aqueous medium. Increase in the ethanol content increased the amount of aldehyde generated. FTIR spectra of oxidized pectin systems show a carbonyl peak at 1734 cm(-1).
