Starch unfrozen water

Frequency sweeps (at a constant deformation, y = 4%) at different times and storage temperatures for the following samples (a) starch-sucrose-water (b) CSXW starch-sucrose-xanthan gum-water unfrozen quickly frozen without storage A quickly frozen and stored 91 days at — 18°C V quickly frozen and stored 91 days at — 80°C O slowly frozen without storage O slowly frozen and stored 91 days at — 18°C. 

FIGURE1.171 HNMR spectra of unfrozen water in hydrated starch powder at (a) h=0.3 g/g (solid lines) and in CDClj medium (dashed lines), (b) on addition of Qc (4.8 wt%)+A-300 (4.8 wt%) at h=0.2 g/g (pretieated at 70°C) (solid lines) and then placed in CDCI3 (dashed lines), and (c) with addition of 0.5 g/g (solid lines) or 1 g/g DMSO (dashed lines).
