Abstract
A process for fractionating agaroid compositions by dissolving the agaroid in a glycol, precipitating a first fraction by cooling and precipitating a second fraction by incorporating a nonsolvent to form two fractions substantially more soluble in water than the initial agaroid. Optionally the solubility of either fraction can be converted to conventional solubilities.
Claims6
A process for encapsulating a core with an agaroid shell comprising surrounding the core with an agaroid composition which exhibits ESA qualities and exposing said agaroid composition to water to result in a shell of gelled agaroid composition around the core material.
