“…Scientists from Kuban State Technical University have proved that vegetable, fruit, and berry ingredients containing pectin substances, proteins, cellulose, hemicellulose, are able to form protein-polysaccharide complexes with flour proteins. In their opinion, this increases the moisture-holding capacity of proteins, which increases the strength of the capillary moisture bond, thereby contributing to the stabilization of the dough structure, improving the quality of products, increasing the yield, slowing down staling [20].…”
