Enzymatic cross-linking of protein-encapsulated oil particles by complex coacervation. A complex coacervate of oil particles, each encapsulated in a protein shell, is stabilized by gelling the protein shell and is subsequently enzymatically cross-linked to form thermostable capsules of about 100-300...http://www.google.de/patents/US6325951?utm_source=gb-gplus-sharePatent US6325951 - Enzymatically protein-encapsulating oil particles by complex coacervation
