The aim of the present study was to investigate the effectiveness of whey proteins when mixed with hot-water extracts of Artemisia and Capparis spp. against lipid peroxidation induced by lead acetate in rats. Chemical composition and antioxidant activities of hot-water extracts of Artemisia and Capparis spp., ingested individually or mixed with whey proteins, were estimated and evaluated. Gluta...

The simultaneous separation of bovine whey proteins [alpha-lactalbumin and beta-lactoglobulin (A+B)] and soybean proteins was performed, for the first time, by capillary electrophoresis. Different experimental conditions were tested. The most suitable consisted of 0.050 M phosphate buffer (pH 8) with 1 M urea and 1.2 mg/ml methylhydroxyethylcellulose, UV detection at 280 nm, 15 kV applied volta...

The aim of this study was to produce a colloidally stable whey protein concentrate enriched in β-casein. Microfiltration (MF) skim milk completed at ∼7 °C (pore size 0.1 μm) followed by ultrafiltration the MF permeate ∼9 β-casein-whey fraction (BWPC). casein:whey ratio BWPC system ∼25:75. Skim then added retentate level supplying 0, 0.1, 0.3 and 0.5% (w/w) total protein, evaporation spray dryin...

Whey protein is a byproduct of cheese, casein, and Greek yogurt produced in Europe, North America, Australasia. It substantial source functional proteins peptides for the worldwide food industry. α-Lactalbumin (α-La) globular that can be isolated from WPI (whey isolates) using techniques such as chromatography/gel filtration, membrane separation, etc. α-La used elaboration foods very good with ...

The objective of this study was to determine the effect of dietary supplementation with whey powder (WP, 1g/kg feed) from weaning to slaughter (150 d) on dry-aged loin quality of pigs. Fifty-eight pigs were randomly divided into two dietary treatment groups (seven replications of four pigs per treatments). Basal diet with 0.1% whey powder was supplied to the WP group. Basal diet was used for th...

A randomized study was planned to compare the effects of whey and egg albumin protein supplements in dialysis patients. Fifty adult patients were randomized to receive either whey protein or egg albumin as per their deficit calculated from K/DOQI recommendations. Actual intake was calculated from three-day dietary diary. Assessment of nutritional status was done by serum albumin and bioelectric...

BACKGROUND: Use of lactose-rich concentrates from dairy processes for the induction of recombinant gene's expression has not received much attention although they are interesting low cost substrates for production of recombinant enzymes. Applicability of dairy waste for induction of recombinant genes in Escherichia coli was studied. Clones expressing Lactobacillus phage muramidase and Lactobaci...

Skeletal muscle satellite cells (SCs) are involved in remodeling and hypertrophy processes of skeletal muscle. However, little knowledge exists on extrinsic factors that influence the content of SCs in skeletal muscle. In a comparative human study, we investigated the muscle fiber type-specific association between emergence of satellite cells (SCs), muscle growth, and remodeling in response to ...

This study focuses on the optimisation of cheese whey formulated media for the production of hyaluronic acid (HA) by Streptococcus zooepidemicus. Culture media containing whey (W; 2.1g/L) or whey hydrolysate (WH; 2.4 g/L) gave the highest HA productions. Both W and WH produced high yields on protein consumed, suggesting cheese whey is a good nitrogen source for S. zooepidemicus production of HA...
