Beschreibung
Zusammenfassung:	Aqueous compositions are disclosed herein comprising at least xanthan gum and insoluble alpha-glucan, wherein: (i) at least about 50% of the glycosidic linkages of the insoluble alpha-glucan are alpha-1,3 glycosidic linkages, (ii) the weight-average degree of polymerization of the insoluble alpha-glucan is at least 10, and (iii) the insoluble alpha-glucan is in the form of particles having a degree of crystallinity of at least about 0.65. Further disclosed are methods for producing these compositions, as well as using them in various products. L'invention divulgue des compositions aqueuses comprenant au moins de la gomme de xanthane et de l'alpha-glucane insoluble, dans lesquelles : (i) au moins environ 50 % des liaisons glycosidiques de l'alpha-glucane insoluble sont des liaisons glycosidiques alpha-1,3, (ii) le degré de polymérisation moyen en poids de l'alpha-glucane insoluble est d'au moins 10, et (iii) l'alpha-glucane insoluble est sous la forme de particules ayant un degré de cristallinité d'au moins environ 0,65. L'invention divulgue en outre des procédés de production de ces compositions, ainsi que de leur utilisation dans divers produits.
