Abstract
Abstract Rice flour obtained from medium and/or short grain rice is hydrated with water under selected conditions to improve baking performance and obtain improved quality rice-containing baked products. A novel formulation to prepare a rice flour layer cake free of wheat, milk and eggs is disclosed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
A method for preparing improved quality rice-containing chemically-leavened or yeast-leavened baked products wherein all or most of the wheat flour in the baking formulation has been replaced with rice flour, which comprises the steps of: (a) mixing rice flour having an amylose content below 20% and a low gelatinization temperature with an amount of water and for a time sufficient to wet all the particles; (b) holding the rice flour-water mixture at a temperature of about -25° C. to 77° C. for a period sufficient to hydrate the particles and insufficient to cause undesirable microbial growth in the mixture or cause undersirable heat deterioration of the flour; wherein steps (a) and (b) are performed in the absence of added sugar; and wherein the intensity of the mixing of step (a) and the holding time and temperature of step (b) are interrelated as follows: if the mixing of step (a) is vigorous, the minimum holding time is shorter than for a simple blending; and for a given mixing intensity, the minimum holding time is longer at the lower temperatures than at the higher temperatures; (c) mixing the treated rice flour of step (b) into a baking formulation; and (d) baking the formulation of step (c).
Claim 2
Independent Claim
204 words
A method for preparing improved quality rice-containing chemically-leavened or yeast-leavened baked products wherein all or most of the wheat flour in the baking formulation has been replaced with rice flour, which comprises the steps of: (a) mixing rice flour having an amylose content below 20% and a low gelatinization temperature with an amount of water and for a time sufficient to wet all the particles; (b) holding the rice flour-water mixture at a temperature of about -25° C. to 77° C. for a period sufficient to hydrate the particles and insufficient to cause undesirable microbial growth in the mixture or cause undersirable heat deterioration of the flour; wherein steps (a) and (b) are performed in the absence of added sugar; and wherein the intensity of the mixing of step (a) and the holding time and temperature of step (b) are interrelated as follows: if the mixing of step (a) is vigorous, the minimum holding time is shorter than for a simple blending; and for a given mixing intensity, the minimum holding time is longer at the lower temperatures than at the higher temperatures; (c) mixing the treated rice flour of step (b) into a baking formulation; and (d) baking the formulation of step (c).
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein the baking formulation is free of wheat, milk, and egg.
Claim 4
Dependent Claim
11 words
The method claim 2 wherein the baked products are chemically-leavened cakes.
Claim 5
Dependent Claim
222 words
In a method of preparing chemically-leavened or yeast-leavened baked products wherein most or all of the wheat flour has been replaced with rice flour wherein a baking formulation is mixed and baked; the improvement comprising treating the rice flour prior to the addition to the baking formulation to improve baking performance so as to obtain improved quality baked goods, the treatment comprising the steps of: (a) mixing rice flour having an amylose content below 20% and a low gelatinization temperature with an amount of water and for a time sufficient to wet all the particles; and (b) holding the rice flour-water mixture at a temperature of about -25° C. to 77° C. for a period sufficient to hydrate the particles and obtain rice flour with improved making performance and insufficient to cause undesirable microbial growth in the mixture or cause undersirable heat deterioration of the flour; wherein steps (a) and (b) are performed in the absence of added sugar; and wherein the intensity of the mixing of step (a) and the holding time and temperature of step (b) are interrelated as follows if the mixing of step (a) is vigorous, the minimum holding time is shorter than for a simple blending; and for a given mixing intensity, the minimum holding time is longer at the lower temperatures than at the higher temperatures.
Claim 6
Dependent Claim
222 words
In a method of preparing chemically-leavened or yeast-leavened baked products wherein most or all of the wheat flour has been replaced with rice flour wherein a baking formulation is mixed and baked; the improvement comprising treating the rice flour prior to the addition to the baking formulation to improve baking performance so as to obtain improved quality baked goods, the treatment comprising the steps of: (a) mixing rice flour having an amylose content below 20% and a low gelatinization temperature with an amount of water and for a time sufficient to wet all the particles; and (b) holding the rice flour-water mixture at a temperature of about -25° C. to 77° C. for a period sufficient to hydrate the particles and obtain rice flour with improved making performance and insufficient to cause undesirable microbial growth in the mixture or cause undersirable heat deterioration of the flour; wherein steps (a) and (b) are performed in the absence of added sugar; and wherein the intensity of the mixing of step (a) and the holding time and temperature of step (b) are interrelated as follows if the mixing of step (a) is vigorous, the minimum holding time is shorter than for a simple blending; and for a given mixing intensity, the minimum holding time is longer at the lower temperatures than at the higher temperatures.
