Abstract
In a method for obtaining aqueous gels based on galactomannan and xanthan, the xanthan employed has first been subjected to a treatment resulting in partial or total deacetylation before being introduced in the mixture in which the ratio of deacetylated xanthan to galactomannan is within the range of 15/85 to 90/10. Potential applications include the food industry, explosives or air-treatment products.
Claims8
A gelling composition consisting essentially of xanthan and a galactomannan gum selected from the group consisting of carob gum, tara gum, Espina Corona gum and mixtures thereof, wherein said xanthan has been subjected to a total or partial deacetylation treatment and wherein the ratio of deacetylated xanthan to galactomannan is from about 15/85 to 90/10.
A method of obtaining aqueous gels having a base of a galactomannan gum and xanthan, said galactomannan gum selected from the group consisting of carob gum, tara gum, Espina Corona gum and mixtures thereof, the method comprising the steps of subjecting the xanthan to a total or partial deacetylation treatment, mixing the deacetylated xanthan with the galactomannan at a ratio of from about 15/85 to 90/10;
- combining the resulting mixture with an aqueous phase;
- heating the resulting mixture to from about 75.degree. to 90.degree. C.;
- and cooling.
