Abstract

The ability of groundnut protein to emulsify soybean oil was studied under various experimental conditions. The emulsification capacity (EC) of groundnut protein isolate was highest at 5 mg/ml protein concn. The EC vs. pH profile resembled a typical protein solubility curve and the EC of groundnut protein isolate was greatest at pH 10.0. NaCl at low concn. (0.05-0.2M ) increased the EC of protein dispersed, in the pH range 7-10. Groundnut protein isolate showed poor emulsifying properties in water (pH 6.8) in contrast to casein or soybean protein. Results with groundnut flour indicated that it was a less effective emulsifier than the protein isolate. EC increased with the fineness of the flour, indicating the influence of particle size. A smaller amount of oil was emulsified at higher mixing speeds.
