Abstract

The invention relates to a method for obtaining saturated or unsaturated oligo-mannuronates, characterized in that it consists in carrying out the following steps : a) brown algae are dispersed in an acidic medium in a heated state, having a pH of less than or equal to 2; b) the insolube fraction is separated by filtering from the soluble fraction obtained in step a), said insoluble fraction containing algal cellulose from said algae and the A-L guluronic (G) and B-D-mannuronic (M) blocks; the pH of said insoluble fraction is adjusted to approximately 2.8 by adding a base; d) the insoluble fraction is separated by filtering from the soluble fraction obtained in step c), said soluble fraction containing B-D mannuronic acid (M) blocks; e) the soluble fraction obtained from step d) is depolymerized acidically or enzymatically or acidically/enzymatically in order to obtain saturated and/or unsaturated oligomannuronates.
