Abstract:
A method of protein-encapsulating oil particles by complex coacervation comprising:forming a dispersion in water of at least one positively charged protein colloid and at least one negatively charged colloid;adding an oil to said dispersion and agitating to form a coarse emulsion of oil particles;first forming a complex coacervate at ambient temperature;cooling said complex coacervate to a gel temperature in the range of about 20.degree. C. to about 27.degree. C. to deposit a stabilized protein shell around said oil particles and further cooling to a temperature in the range of about 5.degree. C. to 10.degree. C. to stabilize said protein-encapsulated oil particles over a pH range of about pH 2 to about pH 10; andenzymatically cross-linking said stabilized protein shell to form said protein-encapsulated oil particles.
