Abstract
Abstract A process for producing textural protein food material from krills which is characterized by adjusting the pH of the precipitate obtained by centrifuging the uniformly smashed flesh of the krills to not less than 10, returning the pH to near neutral and then freezing the precipitate to effect texturing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
52 words
A process for producing textural protein food material from krills which comprises mixing uniformly the flesh of the krills, centrifuging the resulting mixture to obtain a precipitate, adjusting the pH of the precipitate to not less than 10, returning the pH to near neutral, and freezing the precipitate to effect texturing thereof.
Claim 2
Dependent Claim
52 words
A process for producing textural protein food material from krills which comprises mixing uniformly the flesh of the krills, centrifuging the resulting mixture to obtain a precipitate, adjusting the pH of the precipitate to not less than 10, returning the pH to near neutral, and freezing the precipitate to effect texturing thereof.
Claim 3
Dependent Claim
32 words
The process according to claim 1, wherein water is added in an amount of from 1 to 10 times the volume of the krill flesh prior to mixing of the krill flesh.
Claim 4
Dependent Claim
29 words
The process according to claim 1, wherein water is added to the precipitate obtained by centrifugation in an amount of 1 to 4 times the volume of the precipitate.
Claim 5
Dependent Claim
21 words
The process according to claim 1, wherein a calcium salt is added to the precipitate after pH adjustment but before freezing.
Claim 6
Dependent Claim
16 words
The process according to claim 4, wherein the calcium salt is calcium chloride or calcium sulfate.
Claim 7
Dependent Claim
25 words
The process according to claim 4, wherein the amount of the calcium salt added is from 0.1 to 2% by weight based on the precipitate.
Claim 8
Dependent Claim
26 words
The process according to claim 1, wherein freezing of the precipitate is carried out at from -5° C. to -15° C. for at least two days.
Claim 9
Dependent Claim
12 words
The process according to claim 1, wherein the frozen precipitate is thawed.
Claim 10
Dependent Claim
53 words
A process for producing textural protein food material from krills which comprises mixing uniformly the flesh of the krills, separating solid material from the resulting mixture, adjusting the pH of the solid material to not less than 10, returning the pH to near neutral, and freezing the solid material to effect texturing thereof.
