Emulsion stabilizing property of Grewia gum in Arachis oil emulsionARACHIS OIL EMULSION

Abstract

The emulsifying property of grewia gum in arachis oil emulsion was evaluated. The gum was extracted by maceration, filtration, precipitation and drying techniques. The gum was used at 0.1 to  0.4% w/v to stabilize arachis oil emulsion containing 7.5% w/v acacia. The globule size, globule number and viscosity of the emulsion were the parameters used to evaluate the stability of the emulsion. There was a  significant difference (P<0.05) in the stability of acaciabased arachis oil emulsion stabilized by grewia gum compared to that of similar emulsion containing acacia alone. The viscosity of the emulsion stabilized by grewia gum did not change appreciably on storage. On the basis of these, grewia gum may  find application as an emulsion stabilizer in arachis oil emulsion containing acacia.
