Sampling from the vat during cheesemaking may be necessary to study impact of curd washing, which affects both whey composition and curd’s aqueous phase. The objective this work was develop a sieving protocol curd–whey samples, ensuring enough time for drainage free whey, while limiting loss phase entrapped in grains. We studied flow rate lactose content sieving. Both measurements showed two-st...

       Food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. Plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. Presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they ...

Glycomacropeptide (GMP) is a C-terminal part (f 106-169) of kappa-casein which is released in whey during cheese making by the action of chymosin. GMP being a biologically active component has gained much attention in the past decade. It also has unique chemical and functional properties. Many of the biological properties have been ascribed to the carbohydrate moieties attached to the peptide. ...

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....

The inability of humans to synthesize essential amino acids (EAA) necessitates the need to increase the levels of these nutrient molecules in certain foods in which they are deficient. Maize ogi is a typical food product for both infants and adults in Africa, but with poor EAA content. This study therefore sought to assess the possibility of increasing the EAA content in maize ogi by processing...

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%...

Ingestion of whey hydrolysate, casein, or soy protein isolate: effects on mixed muscle protein synthesis at rest and following resistance exercise in young men. J Appl Physiol 107: 987–992, 2009. First published July 9, 2009; doi:10.1152/japplphysiol.00076.2009.— This study was designed to compare the acute response of mixed muscle pro...

Whey, is a natural product resulting from coagulation of milk. Herein, whey powder prepared by non thermal method, was optimized and investigated for its anti-microbial potential against twelve bacerial isolates belonging to three bacterial species by agar-well diffusion assay. Minimum Inhibitory Concentration values were determined by tissue culture plate method to check the concentration rang...
