METHOD OF PRODUCING ELECTROSTATICALLY CHARGED GELATIN

摘要

Methods of forming electrostatically charged gelatin are provided. Gelatin i s extracted by an acid extraction method (12) thereby producing a gelatin dispersion (14 ), the pH of which is adjusted to the isoelectric point of the gelatin. The pH of the gelatin dispersion (14) is then further adjusted (22) so as to cause the gelatin to assume an electrostatic charge.
