Abstract
Abstract Process for preparing a full-fat soy protein concentrate having a bland taste and light color and substantially all of its original protein and fat by subjecting dehulled, cracked soybeans to water at 180 DEG F to 212 DEG F, removing the beans from the water, washing the beans in fresh water, and drying to 8-15% moisture. The product is useful as a human or animal food or it may be subjected to further processing to remove the oil to produce a defatted soy protein concentrate useful in preparing a variety of foods.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
A process for preparing a full-fat soy protein concentrate which is very bland in taste and very light in color and contains substantially all of the original protein content, which comprises the sequential steps of: 1. adding dehulled, cracked soybeans to water at 180°-212°F and maintaining the soybeans in the water at that temperature for 10-50 minutes, 2. removing the soybeans from the water, 3. washing the soybeans in fresh hot water, and 4. drying the washed soybeans to 8-15% moisture.
Claim 2
Dependent Claim
81 words

The process of claim 1 wherein the water temperature of step (1) is about 212°F.
Claim 4
Dependent Claim
36 words
The process of claim 1 wherein the dried soybeans of 8-15% moisture content are subsequently subjected to flaking or grinding followed by defatting to produce a product having at least 70% protein on a moisture-free basis.
Claim 5
Dependent Claim
38 words
The process of claim 1 wherein the full-fat soy protein concentrate contains 26-27% fat and 51-52% protein on a moisture-free basis, and more than 90% of the trypsin inhibitor in the untreated dehulled, cracked soybeans has been destroyed.
Claim 6
Dependent Claim
20 words
The process of claim 1 wherein the the time for maintaining the soybeans in water at 180°-212°F. is 15-40 minutes.
