A glue stick is comprised of solidified adhesive mounted in a lipstick-like push-up tube. Whey is a byproduct of cheese making. Direct disposal of whey can cause environmental pollution. The objective of this study was to use whey protein isolate (WPI) as a natural polymer along with polyvinylpyrrolidone (PVP) to develop safe glue sticks. Pre-dissolved WPI solution, PVP, sucrose, 1,2-propanedio...

The Hexi Corridor, an important part of the Silk Road Economic Belt, is considered the poorest, most water scarce, and most ecologically fragile area in China. Establishing efficient strategies for water management in an integrated manner is utterly important. This paper evaluates the spatio-temporal trends of water stress (2003–2015) in the Shule (SLRB), Heihe (HHRB), and Shiyang (SYRB) River ...

Dairy fouling is a ubiquitous problem in food processing, however, the mechanism not fully understood and investigations arose mainly from experiments with model systems that contained only whey proteins, typically reconstituted protein isolate powder (WPI). The effect of casein on has been rarely considered despite it major component milk proteins. To fill this gap, protein-based fluids contai...

A novel versatile biocompatible hydrogel of whey protein isolate (WPI) and two types tannic acid (TAs) was prepared by crosslinking WPI with TAs in a one-step method at high temperature for 30 min. is one common protein-based preparation which used formation. The obtained WPI-TA hydrogels were disc form retained their integrity after sterilization autoclaving. Two TA preparations differing mole...

An economical and environmentally friendly whey protein fractionation process was developed using supercritical carbon dioxide (sCO(2)) as an acid to produce enriched fractions of α-lactalbumin (α-LA) and β-lactoglobulin (β-LG) from a commercial whey protein isolate (WPI) containing 20% α-LA and 55% β-LG, through selective precipitation of α-LA. Pilot-scale experiments were performed around the...

Whey protein isolate (WPI) microgels formed via cold-set gelation encapsulated vitamin D3 (VD3) forming VD3 WPI (WPI/VD3) microgels. The microgel encapsulation efficiency and stability against temperature (72 °C for 15 s or 63 30 min), UV-light (254 nm) four-week storage (4, 20 ?20 °C) was analysed. up to 98% of VD3. Moreover, the significantly improved compared with control when exposed enviro...

Oil-in-water (O/W) nanoemulsion allows the preparation of lipophilic nutrients such as carotenoids in liquid form, which may improve their bioavailability and broaden applications. In the present study, polyoxyethylene sorbitan monolaurate (Tween 20, TW-20), decaglycerol monolaurate (DML), octenyl succinate starch (OSS), whey protein isolate (WPI), and finally a blend of TW-20 and WPI (1 % by m...

Pure whey protein isolate (WPI)-based cast films are very brittle due to its strong formation of protein cross-linking of disulphide bonding, hydrogen bonding as well as hydrophobic and electrostatic interactions. However, this strong cross-linking is the reason for its final barrier performance. To overcome film brittleness of whey protein layers, plasticisers like glycerol are used. It reduce...

BACKGROUND High hyperbaric pressure treatment of whey protein isolate (WPI) causes changes in the protein structure that enhances the anti-oxidant and anti-inflammatory effects of WPI. OBJECTIVE The aim of this study was to compare the anti-oxidant and anti-inflammatory effects of pressurized whey protein isolate (pWPI) vs. native WPI (nWPI) hydrolysates in Caco-2 cells exposed to hydrogen pe...

The objective of this study was to investigate the structural changes of whey proteins in solution during continuous flow through a novel UV reactor that was designed to minimize poor UV penetration and heterogeneous UV dose distribution. Varying UV irradiation doses were obtained by controlling the flow rate and the mixing speed of the liquid through the reactor. Aqueous solutions of whey prot...
