Spray-drying and ultrasonication processing of camel whey protein concentrate: Characterization and impact on bioactive properties.

The production of whey protein concentrates (WPC) from camel milk whey represents an effective approach to valorize this processing byproduct. These concentrates harbor active ingredients with significant bioactive properties. Camel WPC were spray-dried at inlet temperature of 170, 185 and 200°C, or ultrasonicated (US) for 5, 10, and 15 min, then freeze-dried to obtain fine powder.
