BACKGROUND Evidence suggests an inverse relationship between soy protein intake and serum concentrations of male sex hormones. Anecdotal evidence indicates that these alterations in serum sex hormones may attenuate changes in lean body mass following resistance training. However, little empirical data exists regarding the effects of soy and milk-based proteins on circulating androgens and exerc...

Resistance exercise and whey protein supplementation are effective strategies to activate muscle cell anabolic signaling and ultimately promote increases in muscle mass and strength. In the current study, 46 healthy older men aged 60-75 (69.0 ± 0.55 years, 85.9 ± 1.8 kg, 176.8 ± 1.0 cm) performed a single bout of unaccustomed lower body resistance exercise immediately followed by ingestion of a...

Vitamin B12 is a water-soluble molecule composed of a tetrapyrrolic complex with a cobalt atom at its centre. It is an essential regulatory element, synthesized only by bacteria; for this reason it is present only in food of animal origin and the daily requirement for humans is about 1 to 2 mg. Since milk and dairy products provide a significant dietary cobalamin intake, an ultra performance li...

UNLABELLED Dairy proteins are amenable to structural modifications induced by high temperature, shear, and moisture; in particular, whey proteins can change conformation to new unfolded states. The change in protein state is a basis for creating new foods. The dairy products, nonfat dried milk (NDM), whey protein concentrate (WPC), and whey protein isolate (WPI) were modified using a twin-screw...

Classical methods of the extraction of active ingredients from the plant material are expensive, complicated and often environmentally unfriendly. The micelle-mediated extraction method (MME) seems to be a good alternative. In this work, extractions of elderberry blossoms (Flos Sambuci) were performed using MME methods. Several popular surfactants and whey protein concentrate (WPC) was applied ...

Central composite design of Response Surface Methodology (RSM) was used to study the effect of sodium chloride; NaCl (0.5-1%) and salt replacer potassium chloride KCl (0.5-1%) in combination with whey protein concentrate (0.5-1.5%) and black gram flour (2-4%) on the overall acceptability, saltiness and instrumental hardness of low salt restructured chicken nuggets. Reduction of NaCl content to ...

Glycans exhibit enormous structural diversity in nature and are of particular importance for self-cell survival and are often targeted by microbes. In this study, N-glycans (374.9 pmol/mg in dry delipidated weight) were enzymatically released from bovine milk whey protein concentrate, and they were isolated and analyzed by a two-dimensional HPLC mapping technique and/or by MALDI-TOF mass spectr...
