  • A DSC and NMR-Relaxation study of the molecular mobility of water protons interacting with chemically modified starches

    Publication

    - Russian Journal of Physical Chemistry B - Year 2017

    Changes in the mobility of water protons in the chemically modified starches (CMS)–water system are studied by differential scanning calorimetry and NMR relaxation. The amounts of unfrozen water at negative temperatures and additional (after gelation) unfrozen for CMS are lower than those for native starch. The proton spin–spin relaxation time T2 for CMS samples, conventionally attributed to the water fraction in starch granules,...

  • Molecular mobility of water protons under interaction with chemically modified starches. DSC and HMR-relaxation investigations

    Publication

    - Fizyka Chemiczna [czas. rosyjskojęzyczne] - Year 2017

    The change of water protons mobility in the system chemically modified starches – water were investigated by DSC and NMR-relaxation methods. The amount of unfrozen water at subzero temperature as well as additional unfrozen water which appears after gelatinization have lower values for chemically modified starches in comparison with the native starch. The proton spin-spin relaxation time Т2 for chemically modified starch samples,...

  • Kinetics and mechanism of the chemically modified starches during gelatinization.

    Publication

    - Year 2013

    Native starch was silicated by means of microwave-assisted reactions with varying doses of reagents. Resulting products were characterized by DSC and HMR-relaxation methods. It was observed that the hydratation of the silicated starches during gelatinization decreases when compared to that of the native potato starch. The amount of unfrozen water for ungelitinizated silicated starches are less than in control samples. At the same...
