Whey proteins are mainly a group of small globular proteins. Their structures can be modified by physical, chemical and other means to improve their functionality. The objectives of this study were to investigate the effect of radiation on proteinprotein interaction, microstructure, and microbiological properties of whey protein-water solutions. Whey protein isolate (WPI) solutions (27-36% prot...

The separation of whey proteins from caseins has traditionally been carried out by precipitation of the caseins, either through destabilisation by rennet or by acidification. Microfiltration (MF) is a membrane filtration process that has been investigated for the fractionation of milk proteins [1,2,3]. Microfiltration membranes with molecualr weight cutoff (MWCO) 0.1 μm can be used to separate ...

Our study compared total C-peptide secretion after administration of whey proteins and whey proteins in combination with glucose with results of classical tests assessing beta cell function in the pancreas of healthy individuals. Eight young, healthy (7 males, 1 female; aged 20-26 years), non-obese (BMI: 17-25.9 kg/m²) participants with normal glucose tolerance underwent six C-peptide secretion...

The aim of this study was to investigate the effect of whey protein on plasma amino acid levels in a mouse model of type II diabetes, using high-performance liquid chromatography (HPLC). The composition and content of amino acids in the whey proteins were analyzed using HPLC. Type I and type II diabetic mouse models were prepared using streptozotocin (STZ) and normal mice were used as a control...

This paper deals with the investigation of the impact of the heat treatment of reconstituted skim milk conducted at different temperatures, and the adding of demineralized whey on the protein solubility, soluble protein composition and interactions involved between proteins in a chemical complex. Commercial skim milk has been reconstituted and heat treated at 75°C, 85°C and 90°C for 20 minutes....

Evidence supports that a high proportion of calories from protein increases weight loss and prevents weight (re)gain. Proteins are known to induce satiety, increase secretion of gastrointestinal hormones, and increase diet-induced thermogenesis, but less is known about whether various types of proteins exert different metabolic effects. In the Western world, dairy protein, which consists of 80%...

Abstract Whey, which is a by-product of the production hard, medium and soft cheeses rennet, called sweet whey has pH 5.9-6.6. The inorganic acid precipitated casein produces an acidic with 4.3-4.6. With estimated 180 million tonnes in 2021, global contains around 1.5 ever-increasingly expensive protein 8.6 lactose, important source carbohydrates for world. Recent research shows that proteins a...

The health benefits currently associated with increased dairy intake may be attributable to the whey component of dairy proteins. The present study evaluated the effects of whey protein supplementation on body composition, lipids, insulin and glucose in comparison to casein and glucose (control) supplementation in overweight/obese individuals for 12 weeks. The subjects were randomised to whey p...

This study evaluated the intestinal anti-inflammatory effects of goat whey in a mouse model of colitis induced by 2,4-dinitrobenzenesulfonic acid that resembles human IBD. At a concentration of 4 g/kg/day, the goat whey improved the symptoms of intestinal inflammation, namely by decreasing the disease activity index, colonic weight/length, and leukocyte infiltration. Moreover, goat whey inhibit...
