Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
81 words
In the process of preparing a starch sponge food product wherein an aqueous slurry of raw starch is heated to completely gelatinize the starch, the resulting starch paste is frozen to set-up the starch matrix, and the frozen matrix is allowed to thaw and is dehydrated to yield the starch sponge product, the improvement consisting of adding a heat stable gum or gum system to the slurry in an amount sufficient to improve the thermal stability of the starch sponge product.
Claim 2
Dependent Claim
81 words
In the process of preparing a starch sponge food product wherein an aqueous slurry of raw starch is heated to completely gelatinize the starch, the resulting starch paste is frozen to set-up the starch matrix, and the frozen matrix is allowed to thaw and is dehydrated to yield the starch sponge product, the improvement consisting of adding a heat stable gum or gum system to the slurry in an amount sufficient to improve the thermal stability of the starch sponge product.
Claim 3
Dependent Claim
32 words
The process of claim 1 wherein the heat-stable gum or gum system is used in an amount of about 1 to 20% by weight based on the weight of the raw starch.
Claim 4
Dependent Claim
21 words
The process of claim 1 wherein flavoring and/or coloring agents are added to the starch slurry prior to the freezing thereof.
Claim 5
Dependent Claim
18 words
The process of claim 1 wherein the heat-stable gum system is sodium carboxymethylcellulose and a polyvalent metal ion.
Claim 6
Dependent Claim
21 words
The process of claim 4 wherein the polyvalent metal ion is aluminum and is obtained from a water-soluble salt of aluminum.
Claim 7
Dependent Claim
12 words
The process of claim 1 wherein the heat-stable gum is guar gum.
Claim 8
Dependent Claim
16 words
The starch sponge food product having improved thermal stability prepared by the process of claim 1.
Claim 9
Dependent Claim
15 words
The process of claim 1 wherein the improved starch sponge food product is also puffed.
Claim 10
Dependent Claim
13 words
The puffed starch sponge food product prepared by the process of claim 8.
