Abstract

L'invention concerne une biogomme. On obtient une biogomme ayant une dispersabilité améliorée en chauffant la bière de fermentation dans laquelle la gomme est produite en présence d'environ 0,5% à environ 5% d'un dialhéhyde par rapport au poids de biogomme sèche dans la bière. Cette biogomme peut être utilisé comme épaississant des systèmes aqueux.The invention relates to a biogum. A biogum having improved dispersibility is obtained by heating the fermentation beer in which the gum is produced in the presence of from about 0.5% to about 5% of a dialhehyde based on the weight of dry biogum in the beer. This biogum can be used as a thickener in aqueous systems.
