Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
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°-70° 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°-70° C.
Claim 2
Dependent Claim
81 words
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°-70° 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°-70° C.
Claim 3
Dependent Claim
17 words
A process of claim 1 wherein the free cations are H+, Na+, K+, Ca++, Mg++, or Al+++.
Claim 4
Dependent Claim
23 words
A process of claim 1 wherein the aqueous solution is milk and the gellan gum is native, partailly deacetylated, or partially deacetylated clarified.
Claim 5
Dependent Claim
12 words
A process of claim 3 wherein the solution further comprises tetrasodium pyrophosphate.
Claim 6
Dependent Claim
49 words
A process of claim 1 wherein the agueous solution of step (a) comprises one or more cations selected from H+, Li+, Na+, K+, Rb+ Cs+, Fr+, Be++, Mg++, Ca++, Sr++, Ba++, Ra++, B+++, Al+++, Ga+++, In+++, or Tl+++ and a sufficient amount of suquestrant to dissolve the gellan gum.
Claim 7
Dependent Claim
20 words
A process of claim 5 wherein said sequestrant is trisodium orthophosphate, ethylenediaminetetraacetic acid, sodium citrate, tetrasodium pyrophosphate or sodium hexametaphosphate.
Claim 8
Dependent Claim
13 words
A process of claim 1 wherein the aqueous solution further comprises a glycol.
Claim 9
Dependent Claim
14 words
A process of claim 1 wherein the gellan gum is dissolved in deionized water.
Claim 10
Dependent Claim
35 words
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.
Claim 11
Dependent Claim
35 words
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.
