Abstract

Abstract Storage stable aqueous batters are provided for use in the preparation of leavened culinary products. To the batter is added a quantity of powdered edible acid sufficient to maintain the pH at an acid level below about 5 to inhibit microbial growth. Particles of alkaline leavening agent, encapsulated in a water insoluble coating are also added to the batter. The alkaline leavening agent is capable of dispersing in the batter ingredients at a cooking temperature safely above the storage temperature to release the leavening agent into the acid batter mixture, thereby neutralizing the acid, and leavening the product. The batter premixture is storable with preservation against microbial growth, and the acid-base leavening system isolated to avoid pre-reaction prior to preparing a leavened product.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 104 words
A method for preparing a storage stable culinary product comprising the steps of (a) forming an aqueous unleavened batter, (b) adding to said batter a sufficient amount of an edible acid so as to lower the pH thereof to below about 5, and (c) adding to said batter an edible alkaline leavening agent encapsulated in a normally water-insoluble, edible material, said alkaline leavening agent in a quantity sufficient to raise said pH to a level in the range of approximately 6 to 7, whereby said acid inhibits bacterial growth for preservation of said batter and is isolated from said leavening agent by said encapsulation.
Claim 2
Independent Claim 104 words
A method for preparing a storage stable culinary product comprising the steps of (a) forming an aqueous unleavened batter, (b) adding to said batter a sufficient amount of an edible acid so as to lower the pH thereof to below about 5, and (c) adding to said batter an edible alkaline leavening agent encapsulated in a normally water-insoluble, edible material, said alkaline leavening agent in a quantity sufficient to raise said pH to a level in the range of approximately 6 to 7, whereby said acid inhibits bacterial growth for preservation of said batter and is isolated from said leavening agent by said encapsulation.
Claim 3
Dependent Claim 11 words
The method of claim 1 wherein said agent is sodium bicarbonate.
Claim 4
Dependent Claim 17 words
The method of claim 1 wherein the edible material encapsulating said leavening agent is an edible fat.
Claim 5
Dependent Claim 21 words
The method of claim 2 wherein said agent further comprises a plastic hydrogenated shortening and a fat as the encapsulating material.
Claim 6
Dependent Claim 18 words
The method of claim 1 comprising the further step of adding to said batter an edible fungistatic agent.
Claim 7
Dependent Claim 13 words
The method of claim 5 wherein the edible fungistatic agent is sorbic acid.
Claim 8
Dependent Claim 9 words
A product prepared by the method of claim 1.
Claim 9
Dependent Claim 18 words
The method of claim 1 wherein said pH is in the range of about 3.9 to about 4.7.
Claim 10
Dependent Claim 22 words
The product prepared by the method of claim 7 wherein said batter comprises a mixture of flour, eggs, sugar and milk solids.
