STUDY THE PHYSICOCHEMICAL AND FUNCTIONAL PROPERTIES OF GUM EXTRACTED FROM LOCAL OKRA PODS

Abstract

The study includes extraction of gum from okra by using water as asolvent nd study physic-chemical of okra gum compared with Arabic gum and acacia, The results of physical properties of okra gum showed that the value of pH6.06,density and specific gravity were 1.029 gm/cm3,and 1.0414,the refractive index 1.3342,viscosity was 78.17 cent poise,which the value of pH,density and specific gravity,the refractive index,viscosity in Arabic gum and acacia 5.19, 5.02 and 1.0255, 1.256 gm/cm3 and1.0133, 1.0134and1.3335, 1.3334 and 9.1, 9.61 cent poise respectively, The results of functional properties were as follow: swelling index was 90% compared with Arabic gum and acacia 0.20 and 0.20% , solubility was reached 39 and 51% at 25 and 80C° respectively which in less than Arabic gum and acacia 90 and 100%, The results also showed that okra gum had high oil-holding capacity value 0.76 gm gum/gm oil compared Arabic gum and acacia ,The okra gum was succeed to form gels at 4C° using concentration 3 and 4%,which the Arabic gum and acacia did not form gels at different concentrations.
