Claim 0:
1. A colloidal dispersion produced by a process comprising:
(a) providing an aqueous reaction solution comprising sucrose and a glucosyltransferase that synthesizes poly alpha-1,3-glucan, wherein a slurry containing poly alpha-1,3-glucan is produced, and at least 90% of the glycosidic linkages of the poly alpha-1,3-glucan are alpha-1,3-glycosidic linkages;
(b) filtering the slurry to provide a wet cake of the poly alpha-1,3-glucan, wherein the poly alpha-1,3-glucan is not dried; and
(c) dispersing the wet cake to provide a colloidal dispersion comprising water and the poly alpha-1,3-glucan,
wherein the poly alpha-1,3-glucan of the colloidal dispersion is comprised in particles that have an average diameter of 5 nm to 200 nm.
