Ultrafiltration through Carbosep M(4) mineral membrane of protein solutions of decreasing complexity (whey before and after centrifugation or clarification, beta-lactoglobulin) was studied. Mathematical models were used to explain variations in flux with time. Taking into account variations in protein retention and hydraulic resistance of the membrane during ultrafiltration, proteins and lipoproteins were found to be involved not only in the polarization layer (reversible fouling leading to a difference in the osmotic pressure), but also in irreversible fouling by adsorption. Morever, the presence of particles (e.g., inorganic precipitates) in whey explains the build-up of a deposit over and within the membrane which contributes to the decline in flux after 1 h ultrafiltration. The relative importance of these phenomena was quantified.

Emulsions play an important role in food systems by encapsulating and delivering active compounds, but maintaining their stability under various conditions can be challenging. This study explored how the concentrations of Tremella polysaccharides (TPs) (0-0.75 %) affects the structural of whey protein isolate (WPI) and the stability of their emulsions at pH 4.

Whey proteins, the most abundant proteins in human milk (HM), play a vital role in the growth and development of infants. This review first elaborates on the main components of HM whey proteins, including various proteins with specific functions, and details the functions of these proteins in terms of infant nutrition, immunity, as well as growth and development. Secondly, it analyzes factors that affect HM whey proteins, such as maternal differences, dietary habits, and geographical differences.

Goat milk yogurt infused with hemp extract (HE) is a novel dairy product; however, the unpleasant flavors from hemp terpenes and goat milk may impact its acceptance and popularity. This study aimed to investigate the effect of polymerized whey protein (PWP) on mitigating the hempy flavor of HE-infused goat milk yogurt and its impact on the physicochemical properties, microstructure, and probiotic survivability. Goat milk yogurt samples were infused with either nothing (plain flavor), HE, HE plus whey protein isolate, or HE plus PWP.

Camel α-Lactalbumin (α-LAC) has been shown to exert bioactivities for Reactive oxygen species (ROS) scavenging and anti-inflammation, showing the ability to treat obesity-related metabolic disorders. Herein, we present a novel process to purify α-LAC in a single chromatographic step from camel whey in a flow-through format. We also demonstrate the role of α-LAC modulation strategies for the treatment of obesity.
