Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
109 words
A process for preparing soy protein material having improved solubility which comprises preparing an aqueous slurry of denatured defatted soybean flake material having a weight ratio of said flake material to water of between 1 to 4 and 1 to 20, and ejecting said aqueous slurry through an orifice into a holding chamber at a pressure drop of at least 1 kg/cm 2 ; wherein the NSI of soy protein in said denatured defatted soybean flake material is not more than 70%, and the NSI of soy protein in the resultant pressure ejected slurry is higher than that of said denatured defatted soybean flake material by at least 5%.
Claim 2
Dependent Claim
109 words
A process for preparing soy protein material having improved solubility which comprises preparing an aqueous slurry of denatured defatted soybean flake material having a weight ratio of said flake material to water of between 1 to 4 and 1 to 20, and ejecting said aqueous slurry through an orifice into a holding chamber at a pressure drop of at least 1 kg/cm 2 ; wherein the NSI of soy protein in said denatured defatted soybean flake material is not more than 70%, and the NSI of soy protein in the resultant pressure ejected slurry is higher than that of said denatured defatted soybean flake material by at least 5%.
Claim 3
Dependent Claim
30 words
The process of claim 1, wherein said denatured defatted soybean flake material is obtained by subjecting defatted soybean flake material to at least one of superheating treatment or alcohol extraction.
Claim 4
Dependent Claim
25 words
The process of claim 1, wherein said aqueous slurry of denatured defatted soybean flake material is adjusted to pH 6.5 to 9 prior to ejection.
Claim 5
Dependent Claim
30 words
The process of claim 1, wherein said aqueous slurry prior to ejection is permitted to stand for a period of time sufficient to extract water-soluble materials from said flake material.
Claim 6
Dependent Claim
26 words
The process of claim 1, which further comprises addition of edible oil to the resultant ejected slurry and emulsification in order to obtain a soy milk.
Claim 7
Dependent Claim
20 words
The process of claim 1, which further comprises drying said pressure ejected slurry to obtain an improved soy protein material.
Claim 8
Dependent Claim
21 words
The process of claim 1, which further comprises separating insoluble materials from said resultant pressure ejected slurry to obtain a solution.
Claim 9
Dependent Claim
18 words
The process of claim 7, which further comprises drying said solution to obtain an improved extracted soy protein.
Claim 10
Dependent Claim
50 words
The process of claim 1, which further comprises adjusting said pressure ejected slurry to the pH of about the isoelectric point of the protein to precipitate the protein, separating total solids after said precipitation from the whey and excess liquor, dispersing said solids in water, and neutralizing the resultant mixture.
Claim 11
Dependent Claim
19 words
The process of claim 9, which further comprises drying said neutralized mixture to obtain an improved concentrated soy protein.
Claim 12
Dependent Claim
47 words
The process of claim 7, which further comprises adjusting said solution to the pH of about the isoelectric point of the protein to precipitate the protein, separating said precipitated protein from the whey and excess liquor, dispersing said precipitated protein in water, and neutralizing the resultant mixture.
Claim 13
Dependent Claim
19 words
The process of claim 11, which further comprises drying said neutralized mixture to obtain an improved isolated soy protein.
Claim 14
Dependent Claim
71 words
The process of claim 1, wherein said starting aqueous slurry is prepared by dispersing said flake material in water, adjusting the resultant slurry to the pH of about the isoelectric point of the protein to precipitate the protein with insoluble materials, separating said precipitate and insoluble materials from the whey and excess liquor, dispersing said precipitate and insoluble materials in water, and neutralizing the resultant slurry to pH 6.5 to 9.0.
Claim 15
Dependent Claim
21 words
The process of claim 13, which further comprises drying said resultant pressure ejected slurry to obtain an improved concentrated soy protein.
Claim 16
Dependent Claim
21 words
The process of claim 13, which further comprises separating insoluble materials from said resultant pressure ejected slurry to obtain a solution.
Claim 17
Dependent Claim
18 words
The process of claim 15, which further comprises drying said solution to obtain an improved isolated soy protein.
