Publication number: 20240417489Abstract: Disclosed herein are compositions comprising insoluble alpha-glucan particles having a high degree of crystallinity and small particle size. For example, the alpha-glucan particles can have a degree of crystallinity of at least about 0.65, and/or an average size of less than a micron. At least 50% of the glycosidic linkages of the insoluble alpha-glucan in the disclosed particles are alpha-1,3 glycosidic linkages. Further disclosed are methods of producing insoluble alpha-glucan particles, as well as their use in various applications and products.Type: ApplicationFiled: April 5, 2024Publication date: December 19, 2024Inventors: KYLE HYUN CHANG KIM, YEFIM BRUN, LUCIA DANIELA IONESCU, JUAN DAVID LONDONO, JORGE MOK, JAMES JOSHUA OHANE, LEMUEL TONG
