Experimenting with a new emulsifying agent (tahini) in mineral oil emulsion

The use of tahini, a sesame paste, as an emulsifying agent was the subject of this investigation. Mineral oil emulsion, USP was used as an emulsion model. Tahini partially or completely replaced acacia in the oficial emulsion. The rate of creaming (expressed as percent) and the viscosity of the resulting emulsions were measured. Also, emulsions were prepared containing tahini only. The results show that tahini-prepared emulsions had lower creaming rates and viscosity after one month of storage at room temperature. Thus, a better physical stability was achieved when tahini was used as and emulsifying agent.
