Fibrillization of whey proteins improves foaming capacity and foam stability at low protein concentrations

High Hydrostatic Pressure Pretreatment of Whey Protein Isolates Improves Their Digestibility and Antioxidant Capacity

Whey proteins have well-established antioxidant and anti-inflammatory bioactivities. High hydrostatic pressure processing of whey protein isolates increases their in vitro digestibility resulting in enhanced antioxidant and anti-inflammatory effects. This study compared the effects of different digestion protocols on the digestibility of pressurized (pWPI) and native (nWPI) whey protein isolate...

Guar Foaming Albumin – A Foam Stabilizer

Foaming and foam stability for mixed polymer-surfactant solutions: effects of surfactant type and polymer charge.

Solutions of surfactant-polymer mixtures often exhibit different foaming properties, compared to the solutions of the individual components, due to the strong tendency for formation of polymer-surfactant complexes in the bulk and on the surface of the mixed solutions. A generally shared view in the literature is that electrostatic interactions govern the formation of these complexes, for exampl...

Effects of Enzymatic Hydrolysis on the Foaming Properties of Whey Proteins

Changes in the foaming properties of whey proteins concentrate (WPC) subjected to enzymatic hydrolysis were studied. Activity and stability of the foam generated from the enzymatic hydrolysis of WPC with two proteases: Trypsin from porcine pancreas (analytical quality) and Alcalase 2.4 L FG (Alcalase) (commercial food grade) were analyzed. WPC solution at concentration 100 mg/mL in 50 mM phosph...

Foaming Properties of Whey Protein Isolate and λ-Carrageenan Mixed Systems.

Heating protein with polysaccharide under neutral or near neutral pH can induce the formation of soluble complex with improved functional properties. The objective of our research was to investigate the effects of λ-carrageenan (λC) concentrations and pH on foaming properties of heated whey protein isolate (WPI) and λC soluble complex (h-cpx) in comparison to heated WPI with added λC (pWPI-λC),...
