In this study, the Whey protein isolate (WPI) stabilized disulfiram nanosuspension (DSF-Ns) were prepared by the anti-solvent precipitation-ultrasonication method, and a single factor study was carried out to optimize the formulation based on the particle size and polydispersity index (PDI). The optimized DSF-Ns had a particle size 148.68 ± 1.16 nm, a PDI 0.179 ± 0.012, a surface charge of −25.92 ± 2.12 mV and RDI 102.15%. The transmission electron microscopy analysis indicated the spherical shape of nanoparticles without any clusters. Also, the DSC and PXRD analytical techniques showed an amorphous state of D...

The hydrogel of whey protein isolate coated by lotus root amylopectin enhance the stability and bioavailability of quercetin
In this study, whey protein isolate (WPI)-quercetin (Que)-lotus root amylopectin (LRA) hydrogels (WPI-QUE-LRA) was developed to improve the solubility, stability and bioavailability of quercetin. Results showed that the favorable WPI-QUE-LRA was formed using WPI and LRA in the ratio of 1:2 at pH 7.0. Under this condition, the average size, polydispersity index, zeta potential of the WPI-QUE-LRA was 179.5 nm, 0.271, −18.6 mV, respectively. The analysis of transmission electron microscopy, fourier transform infrared spectroscopy and X-ray diffractometer revealed that the quercetin was successfully encapsulated in WPI-L...

Structural characterization of oleogels from whey protein aerogel particles
Publication date: Available online 12 February 2020Source: Food Research InternationalAuthor(s): S. Plazzotta, S. Calligaris, L. ManzoccoAbstractOleogels intended as fat substitutes were prepared by oil dispersion of aerogel particles obtained through freeze-drying (FD) or supercritical-CO2-drying (SCD) of whey protein isolate (WPI) hydrogels (20 g/100 g). SEM revealed that freeze-dried particles presented larger dimensions than supercritical-dried ones. The latter also showed higher oil dispersibility, forming aggregates with lower dimension (300 nm) than those formed by freeze-dried particles (700 nm). Both particles pre...

Thermal gelation and hardening of whey protein beads for subsequent dehydration and encapsulation using vitrifying sugars
Publication date: Available online 10 February 2020Source: Journal of Food EngineeringAuthor(s): Mackenzie M. Hansen, Valentyn A. Maidannyk, Yrjö H. RoosAbstractSolid beads were developed using whey protein isolate (WPI) and sugars for controlled hardening and vitrification of wall materials. A concentrated mixture of WPI and sucrose in water, intended for use as gelling and glass-forming ingredients, respectively, was used to form liquid feeds with varying pH, viscosities, surface tensions, solids contents and compositions. Using a peristaltic pump, feeds flowed continuously through silicon tubing and formed droplets. Ra...

Physicochemical properties and bioactivity of whey protein isolate-inulin conjugates obtained by Maillard reaction.
Abstract The functional properties and physiological functions of whey protein isolate (WPI) decreased near its isoelectric point (PI). The Maillard reaction covalently binding polysaccharides to proteins is an effective method to improve the functional activities of proteins. WPI-inulin conjugates were prepared by wet-heating method at 70 °C for 2 h, 4 h and 6 h, respectively. New bonds at higher molecular zone appearing at SDS-PAGE, decreased free amino acid content and new formed CN bonds in FT-IR of conjugates compared with WPI confirmed the formation of the covalent bonds between WPI and inul...

Pickering emulsion gels stabilized by high hydrostatic pressure-induced whey protein isolate gel particles: characterization and encapsulation of curcumin
In this study, whey protein isolate (WPI) gel particles were fabricated via high hydrostatic pressure (HHP) treatment and homogenization and the potential of using the particles as food-grade stabilizers to form Pickering emulsions and emulsion gels were studied. The result showed that pH had a significant effect on the properties of WPI gel particles. In the pH range near the isoelectric point (pI) (around pH 5.0), the particles exhibited spherical structure with larger size. The droplet size, creaming stability, microstructure and rheological properties of the Pickering emulsions stabilized by the WPI gel particles were ...
