Factors Determining the Character of Biopolymer—Biopolymer Interactions in Multicomponent Aqueous Solutions Modeling Food Systems

The recent results of thermodynamic studies of the basic physico chemical factors determining character of the biopolymer-biopolymer (protein, polysaccharide) interactions in aqueous medium are discussed. The emphasis is on consideration of such factors as biopolymer structure (molecular mass, size, conformation, charge) and composition of the aqueous medium (content of the low molecular weight inorganic /salts, pH/ and organic /lipophilic molecules: lipids, surface active additives or sucrose/ compounds. Correlation between the character of the biopolymer-biopolymer interactions and biopolymer functional properties in aqueous medium is demonstrated.
