  • Publication number: 20210355299
    Abstract: Disclosed herein are compositions comprising polysaccharide particles with an average size of about 0.1-10 mm. These particles comprise at least (i) about 50%-90% by weight water or an aqueous solution, and (ii) about 10%-50% by weight insoluble alpha-glucan, or an insoluble cationic ether thereof, comprising alpha-1,3-glycosidic linkages and having a weight-average degree of polymerization (DPw) of at least about 100. Further disclosed are methods of preparing these compositions, as well as systems for storing and/or moving them.

  • Patent number: 10087479
    Abstract: Reaction solutions are disclosed herein comprising water, incompletely refined sucrose, and a glucosyltransferase enzyme that synthesizes insoluble poly alpha-1,3-glucan having at least 50% alpha-1,3 glycosidic linkages and a weight average degree of polymerization (DPw) of at least 100. The yield of poly alpha-1,3-glucan by a reaction solution herein is at least 7% of the weight of sucrose that was converted in the reaction solution. Further disclosed are methods of producing poly alpha-1,3-glucan using incompletely refined sucrose, and poly alpha-1,3-glucan produced by these methods.
