Title

THE VISCOELASTIC AND THERMAL PROPERTIES OF QODUME SHIRAZI SEED GUM (ALYSSUM HOMOLOCARPUM)

Pages

  116-128

Abstract

 In this study, DYNAMIC RHEOLOGICAL, structural and thermal properties of ALYSSUM HOMOLOCARPUM SEED GUM (AHSG) were investigated as a function of concentration (1.5, 2, 2.5 and 3% w/v) and temperature (5-85oC). The effects of heating/cooling rate on the rheology of AHSGs were studied using small amplitude dynamic oscillatory shear (SAOS). The LVE of this gum were observed at more than 1% strain. The elastic component was always higher than the viscous one. Mechanical spectra of these gum solutions were obtained by frequency sweep measurement classified into that of weak GELs because G’ was larger than G” throughout the tested frequency range. The complex modulus Showed linear relationship with the frequency. The gums showed dependency behaviour as a function of temperature in the range of 5-85oC. The moduli were dependent on gum concentration. It was shown that strength of AHSG at cooling step is more than heating step. AHSG at concentrations above 2.5% was formed GEL and its GEL was irreversible. GEL formation temperature increased with increasing concentration. FT-IR spectra to understanding their functional groups were recorded in the transmittance mode.
