This study reports the possibility of obtaining WPI-based meringues with small sucrose content (0–15%). The whey protein isolate (WPI) solution (20%, w/v) was whipped and added to foam at concentrations 5, 10 15%. surface tension, viscosity, zeta potential pre-foam solutions, overrun, stability their rheological properties (G?, G? tan (?)) were evaluated. To produce meringues, liquid foams soli...

Actinidin was used to hydrolyse proteins in whey protein isolate (WPI) and milk concentrate (MPC) reduce immunoreactivity of β-lactoglobulin (β-LG) αs1-casein (αs1-CN). Samples were incubated at an enzyme substrate ratio 1:100 (5.21 units actinidin activity g−1 protein) 10 or 60 °C for up 31 5 h, respectively. Protein hydrolysis determined by the degree SDS-PAGE. Antigenicity hydrolysates β-LG ...

BACKGROUND Obesity is a state of chronic low-grade inflammation. Chronic low-grade inflammation is associated with the pathophysiology of both type-2 diabetes and atherosclerosis. Prevention or reduction of chronic low-grade inflammation may be advantageous in relation to obesity related co-morbidity. In this study we investigated the acute effect of dietary protein sources on postprandial low-...

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...

Protein nanofibrils have recently shown unique properties preparing emulsions, with the stability improved after fibrillation of glycated proteins. The objective present study was to physical and chemical emulsions prepared different flexibility. Increasing ethanol level during heating aqueous whey protein isolate (WPI) solutions at pH 2.0 85 °C increased amount semiflexible highly flexible wor...

Abstract Conditions which affect humans are often closely followed by our companion animals, especially in aging populations. Canines present with muscle wasting diseases such as sarcopenia and cachexia a result of or chronic disease. In this 26wk study, goal was to evaluate the effects feeding 1.5x AAFCO CP from whey protein isolate pea compared senior dogs standard diet (45g CP/1000 kcal DM) ...

A protein concentrate (Oryzatein-80™) and a protein isolate (Oryzatein-90™) from organic whole-grain brown rice were analyzed for their amino acid composition. Two samples from different batches of Oryzatein-90™ and one sample of Oryzatein-80™ were provided by Axiom Foods (Los Angeles, CA, USA). Preparation and analysis was carried out by Covance Laboratories (Madison, WI, USA). After hydrolysi...

Endocrine responses to repeated exercise have hardly been investigated and no data are available regarding the mediating influence of nutrition. On three occasions, participants ran for 90 min at 70% VO2max (R1) before a second exhaustive treadmill run at the same intensity (R2; 91.6 ± 17.9 min). During the intervening 4 h recovery, participants ingested either: (i) 0.8 g sucrose·kg-1·h-1 with ...

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...
