  The protein solubility and functional properties of boiled and fried locust were determined at different pH in order to ascertain their suitability as food or food ingredients. The results indicated that the emulsifying activity, emulsion capacity and foaming capacity were affected by pH. For both boiled and fried locust, high values for the parameters were obtained at alkaline region and low values at acidic range except foaming capacity. However, the emulsion stability for both treated locust was of no regular pattern of change at both acidic and alkaline region. However, for both boiled and fried locust the emulsion and foam stability were higher at alkaline region than at the acidic one. The results obtained showed that the protein of the treated locust was slightly soluble and the insolubility of the protein reflects on the other functional properties.

  The functional properties of defatted boiled and fried locust flour as a function of NaCl concentration were investigated. The protein solubility, emulsifying activity, emulsifying capacity, emulsion stability, foaming capacity and foam stability, were determined. The results obtained for boiled locust indicated that the protein solubility and foam stability were slightly increased, while the emulsifying capacity, emulsifying activity and emulsion stability were slightly decreased as NaCl concentration was increased. However, no consistent change was observed in foaming capacity. For fried locust, the protein solubility, emulsifying activity, foaming capacity anf foam stability were increased with NaCl concentration while the emulsifying capacity and emulsion stability were decreased with NaCl concentration. Generally it was observed that addition of NaCl to locust flour improved its functionality.
