Lactobacillus plantarum 21805 encapsulated by whey protein isolate and dextran conjugate for enhanced viability
This study addressed these issues by encapsulating Lactobacillus plantarum into whey protein isolate (WPI) and dextran (DX) conjugates using an encapsulator. The objective of this work is to investigate the effect of encapsulation using WPI and DX conjugates on the viability of Lactobacillus plantarum. The formation of the conjugates was confirmed with absorbance of the intermediate- and late-stage products, degree of grafting, browning index, and gel electrophoresis. Extending the heating time from 1 to 5 h increased the content of high molecular weight conjugates. These conjugates provided better protection of probiotics...

Changes in 24 ‐h energy expenditure, substrate oxidation, and body composition following resistance exercise and a high protein diet via whey protein supplementation in healthy older men
ConclusionResistance exercise significantly increased RMR, SMR, and sedentary EE in healthy older men, but not total EE. PRO alone and combined with RE decreased FM and aided body weight maintenance. This study was registered at clinicaltrials.gov as NCT03299972. (Source: Physiological Reports)

Silver nanoparticle-deposited whey protein isolate amyloid fibrils as catalysts for the reduction of methylene blue
Int J Biol Macromol. 2022 Jun 7:S0141-8130(22)01210-7. doi: 10.1016/j.ijbiomac.2022.06.016. Online ahead of print.ABSTRACTThe unique structural characteristics and superior biocompatibility make the protein nanofibers promising immobilization platforms/substrates for catalysts/enzymes. Metal nanoparticles have been employed as the catalysts in industries due to their excellent catalytic activity and stability, whereas their high surface energy leads to nanoparticle aggregation, thereby hampering their catalytic performance. Here, amyloid fibril (AF) derived from whey protein isolate (WPI) was chosen as the support of silve...

Rheological and microstructural characterisation of heat-induced whey protein isolate gels affected by the addition of caseinomacropeptide
This study developed gels from CMPs, which were isolated by different ultrafiltration systems, and whey protein isolate (WPI), and studied their rheological and ultrastructural characteristics. The 30% WPI gel showed high elastic modulus (G') values and stronger structure than the other samples with CMP. Another gel, with 50% protein, 30% WPI and 20% CMP sample isolated from the 30 kDa retentate, had a weaker structure and lower G' value. The third gel, with 30% WPI and 20% CMP sample from the 5 kDa retentate derived from the 30 kDa retentate, presented intermediate structural strength. Despite the increase in protein conc...

Effects of ultrasound synergized with microwave on structure and functional properties of transglutaminase-crosslinked whey protein isolate
Ultrason Sonochem. 2022 Jan 29;83:105935. doi: 10.1016/j.ultsonch.2022.105935. Online ahead of print.ABSTRACTIn the present study, ultrasound (400 W, U), microwave heating (75 ℃ for 15 min, M) and ultrasound synergized with microwave heating (UM) pretreatments of whey protein isolate (WPI) were applied to investigate and compare their influence on structure, physicochemical and functional characteristic of transglutaminase (TGase)-induced WPI. From the results of size exclusion chromatography, it could be seen that all three physical pretreatments could promote the formation of polymers in TGase cross-linked WPI, whose p...
