The influence of high temperature on whey proteins Whey proteins are heat-labile proteins. According to Donovan and Mullvihill (1987), heat decreases their stability in the following order: PP>α–La>β-Lg>BSA>Ig. Thermal denaturation of whey proteins is two-step process. First step is unfolding, which may be reversible or irreversible and This paper reviews the pathways involved in denaturation and aggregation of whey proteins during heat treatment. Although most studies have used β-Lg alone, this review also includes the role of other whey proteins in aggregation of mixtures of whey proteins such as whey protein isolate (WPI), whey protein con-centrate (WPC), or milk.

Mar 01, 1974В В· The relationship between pH, temperature and rate of denaturation of wheat and soy proteins is complex. Optimum heat treatment of soy flakes, for example, inactivates nearly all biologically active components, but the protein retains most of its functionality. Knowledge about protein denaturation helps to produce food products with desirable Heat coagulation. As has been indicated heat coagulation of proteins is used in preparation of food products, and, fortunately for the mental equilibrium of the cook, heat coagulation of proteins is ordinarily not reversible. Otherwise, many cooked dishes would, with certain treatment, revert to their original uncooked consistency.

One of the objectives of the present work was to establish a comparison among denaturation by heat, sodium dodecyl sulphate (SDS) and dithiothreitol (DTT). At pH 6.0, two bands were resistant to heat treatment, after SDS treatment of the untreated globulin several bands disappeared and two new bands with 26 and 15 kd appeared. Many diseases in humans are caused by mutations that decrease the stability of specific proteins or increase their susceptibility to aggregation. Consequently, the availability of high-throughput methods for assessing protein stability and aggregation properties under physiological conditions (e.g., 37 В°C) is necessary to analyze physicochemical properties under conditions that are closer to

Protein denaturation. When a solution of a protein is boiled, the protein frequently becomes insoluble—i.e., it is denatured—and remains insoluble even when the solution is cooled. The denaturation of the proteins of egg white by heat—as when boiling an egg—is an example of irreversible denaturation. The denatured protein has the same primary structure as the original, or native, protein. of heat and pH on structure and conformation of whey proteins, International Dairy Journal (2012), doi: 10.1016/j.idairyj.2012.08.014.
