Claims9
A process of forming a gel of native gellan gum, deacetylated gellan gum, clarified deacetylated gellan gum, partially deacetylated gellan gum, or partially deacetylated, clarified gellan gum which comprises:
- (a) dissolving 0.05-3% (wt./wt.) of gellan gum in an aqueous solution at 0.degree.-70.degree. C., and
- (b) gelling the dissolved gellan gum with an effective amount of free cations selected from H+, Li+, Na+ K+, Rb+, Cs+, Fr+, Be++, Mg++, Ca++, Sr++, Ba++, Ra++, B+++, Al+++, Ga+++, In+++, or Tl+++ at 0.degree.-70.degree. C.
A self-gelling dry mix comprising gellan gum and a sequestrant in the wt.:wt. ratios of 6:1 to 6.6:1 and a setting salt in an amount ranging from 1.25 to 12.6 times the amount of sequestrant.
