Comparison Study of the Polarization of some Edible Gums

Abstract

The aim of this study was to determine the optically active compounds in deferent edible gum types. In this study Sengal, Seyal and Neem Gums and the mixtures of Sengal/Neem, Seyal/Neem and Sengal/Seyal were used. Polax-2l apperatus was used in the polarization determination. The polarization of the 5% aqueous solution of these gums were determined. The angle of rotation results for the tested gums Sengal, Seyal and Neem were -3.47, 4.317 and -5.867, respectively. The angle of rotation results for the tested gums mixtures were -4.717,-1.223, 0.5 for the mixture of Sengal/Neem, Seyal/Neem and Sengal/Seyal, respectvely. The calculated polarization results for Sengal, Seyal and Neem were -34.7, 43.17,-58.67, respectively, while the polarization results for tested gum mixtures of Sengal/Neem, Seyal/Neem and Sengal/Seyal were -47.17,-12.23 and 5, respectively. According to the obtained results the mixing of gums has a great effect on both the angle of rotation and the polarization results, Thus polarization is powerful tool can be considered any adulteration or mixing of gums
