The impact of whey protein isolate on energy balance regulation
Using C57BL/6J mice fed whey protein isolate (WPI) enriched high fat (HFD) or low-fat diets (LFD), this study tested the hypothesis that WPI directly impacts on adiposity by influencing lipid metabolism. WPI suppressed HFD-induced body fat and increased lean mass at 8 weeks of dietary challenge …

Effects of sucrose on the foaming and interfacial properties of egg white protein and whey protein isolate
Proteins are present in aerated foods to stabilize the air/water interface by lowering the interfacial tension and forming strong interfacial films. Sugars are known to influence the functional properties of protein foams. This study investigated the mechanism responsible for sucrose effects on the …

Digestible indispensable amino acid scores for food proteins
Three experiments were conducted to determine protein quality and to evaluate digestible indispensable amino acid scoring (DIAAS) methodology. Experiment 1 was conducted to compare protein digestibility corrected amino acid scores (PDCAAS) and DIAAS for various plant and animal proteins. Values for …

Emulsification properties of heated whey protein-pectin formed at neutral pH
Interactions between protein and polysaccharides could lead to improved protein functional properties including emulsification properties. Most studies focus on complex coacervates which are formed at pH [less than] pI. Much less attention has been given to interactions at pH [greater than] pI, …
