Whey, a byproduct of the cheesemaking process, is concentrated by processors to make whey protein concentrates (WPC) and isolates (WPI). Only 50% of whey proteins are used in foods. In order to increase their usage, texturizing WPC, WPI, and whey albumin is proposed to create ingredients with new functionality. Extrusion processing texturizes globular proteins by shearing and stretching them in...

in this study, physicochemical and organoleptical properties of muffin cake prepared by substitution of egg white with different levels of whey protein concentrate (wpc) and different levels of guar and xanthan gums in the furmolation were evaluated.wpc at three levels ;25 , 50 and 75 % , guar gum at two levels ; 0.1 and 0.3 % , and xanthan gum at two levels ; 0.1 and 0.15 % , were considered a...

The effect of type of emulsifier, 2 w/w% whey protein concentrate (WPC) or 2 w/w% WPC and 0.1 w/w% chitosan (CH) on the rheological changes and droplet size distribution during the ex vivo digestion of oil in water emulsions (pH 2) containing 1 w/w% rapeseed oil (RSO) were investigated. The procedure was used to mimic the human gastro duodenal digestion in two steps, gastric phase at pH 2 for 3...

Fortified blended foods (FBF) are used for the prevention and treatment of moderate acute malnutrition (MAM) in nutritionally vulnerable individuals, particularly children. A recent review of FBF recommended the addition of animal source food (ASF) in the form of whey protein concentrate (WPC), especially to corn-soy blends. The justification for this recommendation includes the potential of AS...

We have determined the density, rheological behavior and surface tension of whey protein concentrate (WPC) solutions. Densities (r) were measured at concentrations of 0.05–0.40 w/w at temperatures of 20–35C. The results were expressed as a function of temperature and mass fraction (w). This function fit the data with deviations of less than 0.4%. Apparent viscosities (ha) for WPC solutions with...

In this research the 2 sub verities of Rhizopus oligosporus was used for production of antioxidative bioactive compounds from whey protein concentrate (WPC) and apple pomace. Total phenolic compounds, free radical scavenging ability by DPPH and antioxidant protection factort were evaluated in 48 determined treatments. Effect of Incubation temperature in three levels 23, 27, 31°C, incub...

Probiotic dairy foods, especially nonand low-fat dairy products, are becoming popular in the US. A non-fat goat’s milk yogurt containing probiotics (Lactobacillus acidophilus and Bifidobacterium spp.) was developed using heat-treated whey protein concentrate (HWPC) as a fat replacer and pectin as a thickening agent. Yogurts containing non-heat treated whey protein concentrate (WPC) and pectin a...

Dry whey enriched with magnesium and manganese (DW) that contains protein in the amount of 13 %, a concentrate (WPC) content 65 have been chosen as functional bases production complex baking improvers targeted effect. When developing composition improver, rational dosage DW is 2 % by weight flour, WPC – 3 flour. Adding during kneading wheat flour dough predetermines decrease its gluten content,...
