Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A process for the preparation of a soluble protein fraction which comprises extracting a protein-containing vegetable material with an aqueous medium at a pH value between 1.5 and 3, separating the resulting aqueous extract from vegetable material insolubles, treating said aqueous extract by gel filtration at a pH value below 4 and recovering a soluble protein fraction by elution.
Claim 2
Dependent Claim
59 words
A process for the preparation of a soluble protein fraction which comprises extracting a protein-containing vegetable material with an aqueous medium at a pH value between 1.5 and 3, separating the resulting aqueous extract from vegetable material insolubles, treating said aqueous extract by gel filtration at a pH value below 4 and recovering a soluble protein fraction by elution.
Claim 3
Dependent Claim
24 words
A process according to claim 1, in which gel filtration of the aqueous extract is carried out at a pH between 1.5 and 3.
Claim 4
Dependent Claim
17 words
A process according to claim 1, in which the vegetable material is a legume or an oleaginous.
Claim 5
Dependent Claim
17 words
A process according to claim 3, in which the vegetable material is a legume or an oleaginous.
Claim 6
Dependent Claim
24 words
A process according to claim 4, in which the vegetable material comprises whole or defatted soya beans, chick peas, white beans or sesame seeds.
Claim 7
Dependent Claim
23 words
A process according to claim 1, in which the pH of the recovered fraction is adjusted to a value of at least 6.25.
Claim 8
Dependent Claim
23 words
A process according to claim 5, in which the pH of the recovered fraction is adjusted to a value of at least 6.25.
Claim 9
Dependent Claim
26 words
A process according to claim 3, in which the vegetable material is whole soya beans and fat is removed from the aqueous extract before gel filtration.
Claim 10
Dependent Claim
26 words
A process according to claim 6, in which the vegetable material is whole soya beans and fat is removed from the aqueous extract before gel filtration.
