The structure-property relationship and application of multicomponent
protein-polysaccharide and polysaccharide I-polysaccharide 2 gels are
considered Attention is focused on gels based on mixed solutions of ge
latin with dextran, human serum albumin, sodium caseinate, ovalbumin,
agarose, methylcellulose, calcium alginate or sodium alginate. The the
rmodynamic incompatibility of and the formation of complexes by food h
ydrocolloids greatly affect mechanical and other physicochemical prope
rties of gels. Food hydrocolloid mixtures can display both synergistic
and antagonistic effects. Factors such as chemical structure, conform
ational stare and molecular weight of hydrocolloids, as well as the co
mposition of their mixed solution, pH, ionic strength and temperature
are of key importance for the structure of multicomponent gels.
