Abstract
Disclosed herein are compositions comprising (i) an insoluble alpha-glucan and soluble alpha-glucan derivative, or (ii) an insoluble alpha-glucan and additive. These compositions can be in the form of particles, for example, such as particles comprising insoluble alpha-glucan coated with a soluble alpha-glucan derivative and/or additive. Methods are further disclosed for preparing these compositions, as well as various applications of using them.

A composition comprising insoluble alpha-glucan and a soluble alpha-glucan derivative,
- wherein at least about 50% of the glycosidic linkages of the insoluble alpha-glucan are alpha-1,3 glycosidic linkages, and the weight-average degree of polymerization (DPw) of the insoluble alpha-glucan is at least 15,
- wherein at least about 50% of the glycosidic linkages of the soluble alpha-glucan derivative are alpha-1,3 glycosidic linkages, and the DPw of the alpha-glucan portion of the soluble alpha-glucan derivative is at least 15.
