Abstract

The bursting membrane method of measuring the adsorption of emulsifier molecules at oil—water interfaces is presented. For the emulsifiers dodecyl alcohol-10-glycol ether, a whey protein concentrate and egg yolk the adsorption kinetics are measured. It is shown that this method is applicable to determine the adsorption kinetics. Oil—water emulsions have been prepared with the above-mentioned emulsifiers. The influence of the adsorption kinetics of these emulsifiers on the emulsification result is shown.

    Negative slopes correspond to a breakup dominated process, whereas positive slopes indicate a strong impact of coalescence on the Sauter mean diameter. The latter is caused by adsorption rates of emulsifiers onto newly created interface that are slower than the collision rates of droplets (Karbstein, 1994; Karbstein & Schubert, 1995; Michael; Stang, Karbstein, & Schubert, 1994; M.; Stang, Schuchmann, & Schubert, 2001). Emulsification were performed at 40, 60, 80, and 100 MPa which correspond to the energy density of 40, 60, 80, and 100 MJ m−3, respectively (Karbstein, 1994; Karbstein & Schubert, 1995).
