Abstract
Edible complex coacervates and aqueous dispersions of complex coacervates are disclosed, that may be utilized to protect a sensitive substance, e.g., fish oil or omega-3 fatty acids or other hydrophobic substances or sensitive hydrophilic substances. The complex coacervates and aqueous dispersions may be utilized in food products. Methods for producing the complex coacervates and aqueous dispersions are also disclosed.
Claims26
An emulsion having a core-shell capsule structure, wherein the core comprises sensitive substance and the shell comprises a complex coacervate of wax, anionic polymer and cationic polymer.
An aqueous dispersion of complex coacervates, prepared by:
- a. providing a wax solution;
- b. forming a sensitive substance wax solution, comprising combining a sensitive substance with the wax solution;
- c. forming a sensitive substance wax-in-water emulsion, comprising combining the sensitive substance wax solution with at least one anionic polymer;
- and
- d. forming an aqueous dispersion of complex coacervates, comprising combining at least one cationic polymer with the sensitive substance wax-in-water emulsion.
A method for preparing an aqueous dispersion of complex coacervates comprising:
- a. providing a wax solution;
- b. forming a sensitive substance-in-wax solution, comprising combining the wax solution with at least one sensitive substance;
- c. forming a sensitive substance-in-wax emulsion, comprising combining the sensitive substance-in-wax solution with at least one anionic polymer;
- d. forming an aqueous dispersion, comprising dispersing the sensitive substance-in-wax emulsion in an aqueous medium;
- and
- e. forming an aqueous dispersion of complex coacervates, comprising combining at least one cationic polymer with the sensitive substance-in-wax emulsion.
