Whey Protein Fractionation Using Membrane Separation Technology
<p>Large quantities of whey are produced during the manufacture of cheese and casein. This co-product is traditionally processed into whey powder, whey protein concentrates and whey protein isolates using a combination of ultrafiltration and microfiltration processes. These total whey protein …

Chemical and enzymatic modification of whey proteins
"Chemical and enzymatic modifications of whey proteins and their effects on the protein's structural and functional properties were studied. Chemical modification by acylation improved the surface properties of the proteins. Succinylation, in particular, imparted a significant resistance against …

The Fermentation of Cheese Whey by Lactobacilius helvecticus
The lactic acid fermentation of cheese whey permeate by Lactobacillus helveticus was studied. Precipitate formation during autoclaving of whey permeate was examined. Precipitation was found to be pH and temperature dependent. Qualitative analysis suggested that the precipitate was a …

Incorporation of Acid Whey Powders in Probiotic Yogurt
<p>Acid whey powder (A WP) could be used as a functional ingredient for the manufacture of yogurt to obtain benefits that include probiotic effect, nutraceutical benefits, texture improvement, reduced syneresis, and cost effectiveness. Probiotic yogurts, control and that supplemented with …

Ultrafiltering Acid Whey for Incorporation into Probiotic Yogurt
<p>Cottage cheese whey (CCW) could be a good source of predigested nitrogenous compounds for yogurt and probiotic bacteria. The objective of this study was to optimize the incorporation of CCW solids and make them a functional yogurt ingredient. Ultra filtered CCW and CCW were used to replace 1.9, …

Exopolysaccharides Modify Functional Properties of Whey Protein Concentrate
… objectives of this research were to produce whey protein concentrate (WPC) with modified functionality using exopolysaccharides (BPS) producing cultures and utilize modified WPC to replace egg whites in cake. Two different BPS-producing cultures, Lactococcus lactis ssp. cremoris (JFR) and …

Modulation of functional properties of whey proteins by microparticulation
Heat-induced destabilisation (denaturation) of whey proteins (WP) is one of the major problems limiting their application in food products. As a means of modification, and, thereby improvement of the WP functionality, microparticulation of WP using combined heat and high pressure shearing achieved …

Whey-Caseinate Blends and Lactose Hydrolysis in Yogurt Manufacture
… manufacture of yogurt, such as certain modified whey products, would seem to present an economically attractive alternative to the yogurt processor. The Whey Products Institute estimates approximately 18.2 million kg of whey were produced in the U.S.A. in 1980, of which less than half was …

Rumen Microbial Protein Synthesis in Cows Fed Dried Whey
… (38% of total ration dry matter) of dried whey on rumen microbial protein synthesis. Cows were fed total mixed rations consisting of (dry matter basis) 45% corn silage, 10% alfalfa hay, and 45% concentrate mix. The concentrate mix was primarily corn and soybean meal (control) or 85% dried …

Impact of HPLT treatments on micellar caseins and whey proteins
Hochdruck-Tieftemperaturbehandlungen (HPLT) vereinen die Wirkungen hoher Drücke mit denen niedriger Temperaturen und Gefriereffekten. Ziel dieser Untersuchungen ist es den Einfluss von HPLT auf die Hauptproteinfraktionen der Milch zu ermitteln und das Potential dieser Technologie für die …

Maternal Serum and Whey Immune Markers and Eczema Among Infants
… among children and its relation to maternal whey and serum immune markers are considered to either de- or increase risk of the skin disorder. We conducted a prospective study to contrast the role of different maternal immune markers (MIMs) in maternal serum and whey on the development of …

Hydrolyzed-Lactose Whey and Nonfat Dry Milk in Ice Cream
<p>Sweet dry whey was used to replace 25% and 50% of nonfat dry milk solids in ice cream mix. Forty-five batches experimental and control lots of vanilla ice cream were manufactured. A commercial lactase was used to hydrolyze lactose to over 90% conversion and the lactase was inactivated after …

Lactase Activity in Steers Fed Large Amounts of Dried Whey
<p>Large amounts of dried whole whey (86% of concentrate mix, 60% of total dry matter intake) were fed to four Holstein steers in place of corn and soybean meal in the control diet to evaluate the extent and site of lactose digestion in the ruminant's digestive tract. Diets consisted of 70% of the …

Use of Dry Whey and Lactose Hydrolysis in Yogurt Bases
… kg in Switzerland, and 8.0 kg in France (103). Whey is plentiful. According to Delaney (19), approximately 16,000,000 tons of whey are produced in the US yearly. About 80% of the whey is from whole milk cheese and 20% from cottage cheese manufacture. It is estimated that just over one-half of …

Flavor development in lactic fermentation of ultrafiltered cottage cheese whey
… based on protein collected from cottage cheese whey was used to investigate this phenomenon;The whey proteins were concentrated 10-fold by ultrafiltration through a membrane with 30,000 MW cutoff, diluted 1:1 with water and reconcentrated to a final concentration of 6-7% of the initial whey …

The impact of whey protein isolate on energy balance regulation
Using C57BL/6J mice fed whey protein isolate (WPI) enriched high fat (HFD) or low-fat diets (LFD), this study tested the hypothesis that WPI directly impacts on adiposity by influencing lipid metabolism. WPI suppressed HFD-induced body fat and increased lean mass at 8 weeks of dietary challenge …
