Abstract

En el presente documento se desvelan composiciones que comprenden al menos un compuesto derivado de un copolímero de injerto de alfa-glucano (por ejemplo, un éter o un éster) que tiene un grado de sustitución (DoS) de hasta aproximadamente 3.0. Los precursores de estos compuestos derivados son copolímeros de injerto que comprenden una cadena principal de dextrano y cadenas laterales de alfa-glucano. Al menos el 30 % de las uniones glicosídicas de las cadenas laterales del alfa-glucano son uniones alfa-1.3 glicosídicas. Además, se desvelan métodos para producir derivados de un copolímero de injerto, así como su uso en diversas aplicaciones y productos.
