Characterization of O/W emulgels based on whey protein-alginate-inulin coacervates: Influence of temperature and ultrasound as protein preconditioning process
Int J Biol Macromol. 2024 Mar 30:131260. doi: 10.1016/j.ijbiomac.2024.131260. Online ahead of print.ABSTRACTPreconditioning processes in proteins play a crucial role in enhancing their functional properties as surface active agents. Whey protein isolate (WPI, 20 wt%) was preconditioned via temperature (WPIT, 90 °C) or ultrasound (WPIUS, 20 kHz, 80 % amplitude). FTIR and zeta potential analysis demonstrated the effect of the preconditioning process on the secondary structure and surface properties of WPI. WPI-Alginate:Inulin (AI) complex coacervates (CCWPI:AI) were formed at pH 3.0 using WPIT and WPIUS, and the associative...

Improving the properties of whey protein isolate-zein nanogels with novel acidifiers: Re-dispersity, stability and quercetin bioavailability
Int J Biol Macromol. 2024 Apr 1:131284. doi: 10.1016/j.ijbiomac.2024.131284. Online ahead of print.ABSTRACTLow bioavailability of quercetin (Que) reduces its preclinical and clinical benefits. In order to improve Que bioavailability, a novel whey protein isolate (WPI)-zein nanogel was prepared by pH-driven self-assembly and heat-induced gelatinization. The results showed that hydrochloric acid can be substituted by both acetic acid and citric acid during the pH-driven process. After encapsulation, the bioavailability of Que in nanogels (composed of 70 % WPI) induced by different acidifiers increased to 19.89 % (citric acid...

Water in water emulsion stabilized by liposomes developed from whey protein isolate and xanthan gum: Environmental stability and photoprotection effect for riboflavin
Int J Biol Macromol. 2024 Feb 13;262(Pt 2):130036. doi: 10.1016/j.ijbiomac.2024.130036. Online ahead of print.ABSTRACTThe purpose of this work is to explore the feasibility of water in water (W/W) emulsion stabilized with liposomes as a water-soluble nutraceutical carrier. A W/W emulsion system composed of xanthan gum (XG) and whey protein isolate (WPI) with different amount (0.2 %, 0.4 %, and 0.6 %) of liposomes as stabilizer was constructed. Fast green staining observation showed that XG was the internal phase and WPI was the continuous phase respectively. Confocal laser scanning microscopy revealed that with the increas...

Optimizing the ultrasonic extraction of polyphenols from mango peel and investigating the characteristics, antioxidant activity and storage stability of extract nanocapsules in maltodextrin/whey protein isolate
In this study, the extraction and nanoencapsulation of mango peel extract (MPE) were investigated to enhance its stability and preserve its antioxidant properties. Initially, using the central composite design (CCD)-response surface methodology (RSM), optimal conditions for the extraction of MPE via an ultrasonic system were determined to be a temperature of 10.53 °C, a time of 34.35 min, and an ethanol concentration of 26.62 %. Subsequently, the extracted extract was spray-dried and nanoencapsulated using three types of coatings: maltodextrin, whey protein isolate (WPI), and their combination. The results showed that nan...

Radioprotective potential of whey protein against gamma irradiation-induced lingual damage
Discussion: Oxidative stress was stimulated upon IR exposure in tongue, indicated by boosted malondialdehyde (MDA) level, along with a decrease in the total antioxidant capacity (TAC) level, superoxide dismutase (SOD), and catalase (CAT) activities. Additionally, IR exposure depicted an increase of serum IgE, inflammatory cytokines, including tumor necrosis factor-α (TNF-α), interleukin (IL)-6, along with overexpression mRNA levels of nuclear factor kappa-B transcription factor/p65 (NF-κB/p65), and down-regulation of nuclear factor erythroid 2-related factor 2 (NRF2) and heme oxygenase (HO-1) mRNA levels in tongue tissu...

Superabsorbent whey protein isolates/chitosan-based antibacterial aerogels: Preparation, characterization and application in chicken meat preservation
The objective of this study is to fabricate a novel superabsorbent and antibacterial aerogel, which consists of whey protein isolate (WPI) and chitosan (CS). The citric acid (CA) and ε-polylysine hydrochloride (ε-PLH) are incorporated into WPI/CS-based aerogel as cross-linking and antibacterial agent, respectively. The application in meat preservation as an absorbent pad is investigated. Results of water absorption, water vapor absorption and stress-strain show that aerogel comprised of 6 % WPI, 1.2 % CS, 2.0 % CA, and 2.0 % ε-PLH have the best water absorption capacity and stress. The density of WPI/CS/CA/ε-PLH aeroge...

Improved encapsulation effect and structural properties of whey protein isolate by dielectric barrier discharge cold plasma
Int J Biol Macromol. 2023 Dec 5:128556. doi: 10.1016/j.ijbiomac.2023.128556. Online ahead of print.ABSTRACTThe whey protein isolate (WPI) was modified by dielectric barrier discharge cold plasma (DBD) in order to improve its encapsulation efficiency of rutin. In this work, the effect of DBD treatment on structure and physicochemical properties of WPI and the interaction between DBD-treated WPI and rutin were investigated. The results showed that the structural change of WPI leaded to the exposure of internal hydrophobic groups, increasing the interaction site with rutin. The embedding rate of DBD-treated WPI (30 kV, 30 s) ...
