Improving Functionality of Whey Protein Concentrates from Different Sources*

Enzymatic Hydrolysis of Whey Protein Concentrates: Peptide HPLC Profiles

Hydrolysis of whey protein concentrates (WPCs) at different temperatures and pHs, using three enzymes: pepsin, trypsin, and Alcalase, was monitored during more than 5 hr by reversed phase HPLC/UV,

Study of ultrafiltration of defatted whey protein concentrates (WPC) withdrawn from an industrial plant

Optimization of Cheese Whey Ultrafltration/Diafltration for the Production of Beverage Liquid Protein Concentrates with Lactose Partially Removed

The processing of cheese whey pre-concentrated by reverse osmosis is carried out through ultrafiltration in diafiltration mode to produce whey protein concentrates with lower lactose content to be incorporated in beverages. The initial cheese whey protein and lactose contents are 2.13g/100g and 13.22g/100g, respectively.The commercial membranes, GR95PP, supplied by Alfa Laval, Denmark, we...

Properties of Cast Films Made from Different Ratios of Whey Protein Isolate, Hydrolysed Whey Protein Isolate and Glycerol

Whey protein isolate (WPI)-based cast films are very brittle, due to several chain interactions caused by a large amount of different functional groups. In order to overcome film brittleness, plasticizers, like glycerol, are commonly used. As a result of adding plasticizers, the free volume between the polymer chains increases, leading to higher permeability values. The objective of this study ...

Functionality of extrusion--texturized whey proteins.

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...
