Whey protein concentrate fortified with iron

The authors have proved the possibility of obtaining iron-containing protein product by the method of chemical modification of whey proteins and subsequent fermenting protein bifidobacteria. They have researched and theoretically grounded patterns of thermal denaturation of whey proteins when used as the coagulant ferric sulphate. It is noted that iron ions increase the biochemical activity of bifidobacteria and intensify the technological process of fermented products’ production. It is established that denatured whey proteins are actively attacked by the enzymes of bifidobacteria with the formation of more simple compounds. On the basis of the conducted research the authors have developed the technology of fermented whey protein concentrate fortified with iron. It has been found that the received protein concentrates have high functional and consumer properties and have the increased content of digestible iron and a high number of viable cells of bifidobacteria.
