The objective of this research was to check whether the observed low-density water (LDW) to high-density water (HDW) transformation does take place or not in a complex aqueous system like those involved in high pressure processing of food. In-situ measurements of speed-of-sound up to 640 MPa were used for this purpose. After validation of the methodology in liquid water at 25 oC, LDW-to-HDW tra...

The relative uptake and mechanisms of lipid-based emulsions of three different particle diameters by Caco-2 cells were studied. The corn oil-sodium caseinate emulsions showed little or no cytotoxicity even at 2 mg/mL protein concentration for any of the three droplet size emulsions. Confocal laser scanning microscopy (CLSM) of Nile red containing emulsions showed that the lipid-based emulsions ...

Seven treatments (activated charcoal, bentonite, PVPP, yeast cell walls, potassium caseinate, zeolite and grape seed oil) were evaluated for their efficacy in decreasing the concentration of geosmin, responsible for earthy off-flavour in wine. In the red wine the potassium caseinate and grape seed oil treatments decreased the concentration of geosmin by 14% and 83%, respectively, while in the w...

Tiger nut milk (TNM) shows limited colloidal stability, which affects consumer acceptability in many parts of the world where tiger is cultivated. In this study, addition proteins and hydrocolloids was used for improving impact on physical properties acceptance reported. Enriching TNM by 3 g/100 g sodium caseinate 0.1 xanthan gum successfully impeded creaming serum formation resulted a decrease...

Tetrahydrocurcumin (THC) is a natural molecule with anticancerous, antioxidant and other beneficial activities. However, its low aqueous solubility leads to poor bioavailability. Sodium caseinate (NaCas) an ideal protein carrier amphiphilic non-toxic properties, which provides new possibility for improving the of THC. In this study, THC loaded nanoparticles ([email protected]) were successfully...

Cysteine is the rate-limiting amino acid for synthesis of the ubiquitous antioxidant glutathione (GSH). Bovine whey proteins are rich in cystine, the disulfide form of the amino acid cysteine. The objective of this study was to determine whether enzymatically hydrolyzed whey protein isolate (WPI) could increase intracellular GSH concentrations and protect against oxidant-induced cell death in a...
