Abstract
Abstract Soybean beverages are prepared by grinding dry, whole soybeans to a powder having a particle size less than about 420 microns. The powder is mixed with hot water to form a slurry, to soften the particles and to inactivate lipoxygenase. The slurry is homogenized and the pectin and cellulose components and the flatulence factors of the homogenized slurry are broken down by adding enzymes to the homogenized slurry.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
A method for preparing a soybean beverage which comprises: a. grinding whole dry soybeans to a powder of a particle size less than about 420 microns, while avoiding excessive heat generation b. mixing said powder with water at a temperature between about 50° C. and 100° C. to form a slurry to soften the particles and to inactivate lipoxygenase, c. homogenizing the slurry and d. adding enzymes to the homogenized slurry to break down the cellulose, pectin and flatulent components of the homogenized slurry
Claim 2
Independent Claim
84 words
A method for preparing a soybean beverage which comprises: a. grinding whole dry soybeans to a powder of a particle size less than about 420 microns, while avoiding excessive heat generation b. mixing said powder with water at a temperature between about 50° C. and 100° C. to form a slurry to soften the particles and to inactivate lipoxygenase, c. homogenizing the slurry and d. adding enzymes to the homogenized slurry to break down the cellulose, pectin and flatulent components of the homogenized slurry
Claim 3
Dependent Claim
13 words
The process of claim 1 wherein the soybeans are dehulled prior to grinding.
Claim 4
Dependent Claim
17 words
The process of claim 1 wherein the soybean hulls are separated from the ground soybeans after grinding.
Claim 5
Dependent Claim
21 words
The process of claim 1 wherein the enzymes comprise cellulase, pectinase and hemicellulase which can be added individually or in combination.
Claim 6
Dependent Claim
21 words
The process of claim 1 which includes the step of adding a second enzyme composition to break down raffinose and strachyose.
Claim 7
Dependent Claim
16 words
The process of claim 1 wherein the hulls of the soybeans are ground with the soybeans.
Claim 8
Dependent Claim
17 words
The process of claim 1 which includes the step of adding soybean hull fiber to the beverage.
