In the confectionery industry, egg whites are most often used as foaming agents. Other foaming agents, such as soy proteins, blood albumin, sugar beet extract, soap root extract, licorice root, have not found widespread use, since they do not meet the requirements for organoleptic characteristics. Recently, much attention has been paid by manufacturers to the use of milk proteins. The production of dairy products produces significant amounts of whey, which, despite its high nutritional value, is still underutilized in the food industry. The article is devoted to the study of the functional and technological properties of whey proteins, combined mixtures of whey protein concentrate and egg white. Theoretical information on the functional and technological properties of proteins is presented. The technological factors affecting foaming and foam stability are considered. When performing the research, the generally accepted and special research methods were used. The foaming capacity and stability of the protein foam were determined by the Rauch method. Surface tension was measured by the stalagmometric method. Determination of the structure and dispersion of protein foams was carried out using an electron microscope. The functional and technological properties of whey protein concentrate have been investigated. It was found that when whey proteins were used, the whipped masses had stable stability, which was provided by the increased ability of proteins to hydration, surface activity, the type of intermolecular interactions, as well as an increased denaturation temperature and the ability to form gels. Thus, the totality of the studies carried out shows the feasibility of further study and use of whey proteins when creating a new assortment of whipped candy masses.
