Whey protein consumption reportedly alleviates parameters of the metabolic syndrome. Here, we investigated the effects of whey protein isolate (whey) in young mice fed a high-fat diet. We hypothesized that whey as the sole protein source reduced early weight gain associated with retarded growth and decreased concentration of insulin-like growth factor-1. Moreover, we hypothesized that these cha...

A straightforward protocol was developed to produce rosemary particles using whey and soy protein carriers. The post-processing retention of carnosic acid (CA), carnosol (CR) rosmarinic (RA), their bioaccessibility, in vitro antioxidant activity, storage stability were investigated protein-rosemary compared extract (RME). Solids recovery highest for or whey-inulin blend complexed with (R–WPI, R...

In this paper we describe the rheological behaviour of Ca2+-induced cold-set gels of whey protein mixtures. Coldset gels are important applications for products with a low thermal stability. In previous work [1], we determined the state diagram for whey protein mixtures that were heated for 10 h at pH 2 at 80°C. Under these conditions, the major whey protein, b-lactoglobulin (b-lg), forms fibri...

Protein-stabilized emulsions tend to be susceptible droplet aggregation in the presence of high ionic strengths or when exposed acidic gastric conditions due a reduction electrostatic repulsion between protein-coated droplets. Previously, we found that incorporating cinnamaldehyde into oil phase improved resistance whey protein isolate (WPI)-stabilized against induced by NaCl, KCl and CaCl2. In...

Background Protein supplementation in addition to resistance training has been shown to increase muscle hypertrophy and lean mass. Supplemental protein sources differ in amino acid composition, size, structure, and functionality. Animal derived proteins sources such as Beef Protein Isolate (BeefISO), Serum Albumin Concentrate (SuperSerum), Serum Protein Concentrate (SerumPro), whey protein isol...

The effectiveness of acidity and supplementation with different concentration of sodium chloride salt on function properties for whey protein powder prepared from salted and unsalted whey were investigated. The resultant whey protein powder was in a denatured form and contained about 50% protein. Whey protein powder from salted whey was generally more water soluble at any particular pH values (...

Heat pre-treated and non heat pre-treated whey protein isolate (WPI) were hydrolysed using α-chymotrypsin (chymotrypsin), pepsin and trypsin. The in vitro antioxidant activity, ACE-inhibition activity and surface hydrophobicities of the hydrolysates were measured in order to determine if peptides with dual functionalities were present. Dual functional peptides have both biological (e.g. antioxi...

Glycation between proteins and sugars via the Maillard reaction has been shown to improve heat stability of proteins. In this study, inulin, a healthy dietary fiber, was glycated with whey protein isolate (WPI), effects conditions were investigated. Conjugates prepared by freeze-drying mixed WPI inulin solutions at 1:1 6:1 WPI-to-inulin weight ratios followed dry heating 70, 75, or 80 °C for 12...
