BACKGROUND The insulinotropic effect of whey protein is not fully understood and has clinical implications in the regulation of chronic and acute hyperglycemia. SUMMARY This review describes the composition of whey protein and potential mechanisms through which whey exerts an insulinotropic effect, including increasing the gastric emptying rate, effect on incretin hormones particularly gastri...

Protein-stabilized emulsions tend to be susceptible droplet aggregation in the presence of high ionic strengths or when exposed acidic gastric conditions due a reduction electrostatic repulsion between protein-coated droplets. Previously, we found that incorporating cinnamaldehyde into oil phase improved resistance whey protein isolate (WPI)-stabilized against induced by NaCl, KCl and CaCl2. In...

Tang JE, Moore DR, Kujbida GW, Tarnopolsky MA, Phillips SM. Ingestion of whey hydrolysate, casein, or soy protein isolate: effects on mixed muscle protein synthesis at rest and following resistance exercise in young men. J Appl Physiol 107: 987–992, 2009. First published July 9, 2009; doi:10.1152/japplphysiol.00076.2009.— This study was designed to compare the acute response of mixed muscle pro...

The effects of high hydrostatic pressure (HP), protein concentration, and sugar concentration on the gelation of a whey protein isolate (WPI) were investigated. Differing concentrations of WPI solution in the presence or absence of lactose (0-20%, w/v) were pressurized at 200-1000 MPa and incubated at 30°C for 10 min. The hardness and breaking stress of the HPinduced gels increased with increas...

Comparisons of the physical and sensory properties of several commercial egg alternatives in angel food cake formulation were studied. Fourteen samples were investigated for foaming properties at 10 and 20 min whipping time: collagen, Cryogel gelatin, Solugel collagen hydroysates, gelatin, whey protein concentrate, fish protein, whey protein isolate (95% WPI, 90%WPI), hydrolyzed whey protein is...

BACKGROUND We examined the effects of short-term consumption of whey protein isolate on muscle proteins and force recovery after eccentrically-induced muscle damage in healthy individuals. METHODS Seventeen untrained male participants (23 ± 5 yr, 180 ± 6 cm, 80 ± 11 kg) were randomly separated into two supplement groups: i) whey protein isolate (WPH; n = 9); or ii) carbohydrate (CHO; n = 8). ...
