Design of whey protein nanostructures for incorporation and release of nutraceutical compounds in food.
Whey proteins are widely used as nutritional and functional ingredients in formulated foods because they are relatively inexpensive, generally recognized as safe (GRAS) ingredient, and possess important biological, physical, and chemical functionalities. Denaturation and aggregation behavior of these proteins is of particular relevance toward manufacture of novel nanostructures with a number of...
متن کاملEffects of Ohmic Heating on Denaturation of Whey Proteins Solutions: Influence on Whey-Derived Products
Ohmic heating is one of the earliest applications of electricity in thermal processing of food and is receiving increased attention because of its uniform heating of liquids with faster heating rates, which presumably enables obtaining products of a superior quality to those processed by conventional heating technologies. Given the biochemical structure of proteins, it is expectable that ohmic ...
متن کاملExperimental and Modelling Study of the Denaturation of Milk Protein by Heat Treatment
Heat treatment of milk aims to inhibit the growth of microbes, extend the shelf-life of products and improve the quality of the products. Heat treatment also leads to denaturation of whey protein and the formation of whey protein-casein polymer, which has negative effects on milk product. Hence the milk heat treatment conditions should be controlled in milk processing. In this study, the denatu...
متن کاملFunctionality 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...
متن کاملEnzymatic hydrolysis of heat-induced aggregates of whey protein isolate.
The effects of heat-induced denaturation and subsequent aggregation of whey protein isolate (WPI) solutions on the rate of enzymatic hydrolysis was investigated. Both heated (60 °C, 15 min; 65 °C, 5 and 15 min; 70 °C, 5 and 15 min, 75 °C, 5 and 15 min; 80 °C, 10 min) and unheated WPI solutions (100 g L(-1) protein) were incubated with a commercial proteolytic enzyme preparation, Corolase PP, un...
