Ultrafiltration for Homogenization of Wheat Germ Oil:Water System: Droplet Size Distribution and Stability of Emulsion

Wheat germ oil (WGO) in water emulsion is increasingly being used a variety of fields due to its outstanding nutritional and health benefits. To enhance WGO composability, emulsification should be performed allow them dissolve more easily food matrix or active packaging. Membrane promising advanced homogenization technology that has recently been developed. This research focused on application membrane for WGO-in-water by polyether sulfone (PESU) with 0.45 µm pore size, operating pressure from 5 9 bar, fraction range 10–20% w/w, lecithin ratio 0–0.2% w/v were evaluated the mean particle diameters, distribution diameter, stability emulsion, permeate flux. Higher led smaller diameters higher efficiency However, increasing showed opposite trend. Notably, 0 0.2%, increased 3.36 7.72 µm, decreased 98.54 97.68%, flux 105.95 77.45 L h−1 m−2. The results advantage using PESU homogenization, produce emulsions small size (50% volume was less than µm), high (greater 95%), lower emulsifier usage. Results imply premix potential apply emulsion.
