Abstrakt: Low frequency Raman spectra of dehydrated egg white (DEW) and dehydrated heat-treated egg white gel (DHTEWG) were investigated in order to distinguish characteristics spectroscopically. A notable difference has been revealed in the low-lying band frequency; in DEW, it was approximately the same as that of the boson peak reported on many amorphous materials or glasses, on the other hand, in DHTEWG, the frequency was 2?3 times that in the conventional ones. This feature was considered the result of the crosslink of the polymer network in DHTEWG formed before dehydration.
