Abstract

The physical properties of extracted gum from Fenugreek seeds Trigonella foenum graccum L. were determined and compared with both Arabic and Acacia gums. The gum was extracted using water and precipitated with ethanol. There were a number of differences among gums regarding the pH value, density, refractive index and the wavelength. The pH value of the Fenugreek gum was 6.69, while the lowest value was 5.02 in the Arabic gum. In contrast, the density of 1% Fenugreek gum was found to be 1.025 g.ml-1 compared with Arabic gum 1.0133 g.ml-1 and Acacia gum 1.0134 g ml-1. The refractive index values were 1.3340, 1.3335 and 1.3336 for Fenugreek gum, Arabic gum, and Acacia gum, respectively. Moreover, the maximum wavelength of the Fenugreek seeds gum was at 330 nm, while the results observed that both Arabic gum and acacia gum had the same wave length (300 nm). The functional properties of extracted Fenugreek gum were studied; the value of swelling Index was 90.90% compared to both Arabic gum (0.20%) and Acacia gum (0.20 %). The solubility of the Fenugreek gum was 40% and 50% at 25°C, and 80°C, respectively. The results also showed that Fenugreek gum had high oil holding capacity value of 0.88% compared with the Arabic gum and Acacia gum. The Fenugreek gum was succeeded to form gels at 4°C using concentration 1, 2, 3 and 4%, while the Arabic gum and Acacia gum did not form gel at different concentrations.
