Abstract
Abstract A concentrated proteinaceous food material which is suitable for the production of various cooking foodstuffs resembling those of livestock meat which has a texture like that of livestock meat and which shows an excellent water-retaining property is obtained by adding to marine animal meat an edible salt to adjust pH value of said meat in the range of from 6.5 to 7.7 and removing fats and water by use of a hydrophilic organic solvent. In one embodiment the pH of the marine animal meat is adjusted to a value in the range of from 7.2 to 7.7 by using, as the edible salt, a bicarbonate and, at the same time, mixing the meat with common salt or a sucrose fatty acid ester to convert the meat into a meat paste and subsequently removing fats and water by use of a hydrophilic organic solvent.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A method for the manufacture of a concentrated proteinaceous food material suitable for the production of processed foodstuffs which, when reconstituted with water, assumes a textural structure wherein an amorphous aggregate of meat protein is dotted with muscle fibers, resembling that of livestock meat, which method comprises mixing minced marine animal meat with an edible salt to adjust the pH of said meat to a value in the range of from 6.5 to 7.7, said edible salt being selected from the group consisting of common salt, monosodium glutamate, pyrophosphates and polyphosphates then kneading the mixture and contacting the resultant meat with a hydrophilic organic solvent precooled to 0° to 5° C and in an amount sufficient to extract fats and water, and drying the extracted meat thereby producing the proteinaceous food material.
Claim 2
Independent Claim
132 words
A method for the manufacture of a concentrated proteinaceous food material suitable for the production of processed foodstuffs which, when reconstituted with water, assumes a textural structure wherein an amorphous aggregate of meat protein is dotted with muscle fibers, resembling that of livestock meat, which method comprises mixing minced marine animal meat with an edible salt to adjust the pH of said meat to a value in the range of from 6.5 to 7.7, said edible salt being selected from the group consisting of common salt, monosodium glutamate, pyrophosphates and polyphosphates then kneading the mixture and contacting the resultant meat with a hydrophilic organic solvent precooled to 0° to 5° C and in an amount sufficient to extract fats and water, and drying the extracted meat thereby producing the proteinaceous food material.
Claim 3
Dependent Claim
23 words
The method according to claim 1, wherein said hydrophilic organic solvent is one member selected from the groug consisting of methanol and ethanol.
Claim 4
Independent Claim
136 words
A method for the manufacture of a concentrated proteinaceous food material having properties suitable for the production of processed foodstuffs having a structure wherein an amorphous aggregate of meat protein is dotted with muscle fibers, resembling that of livestock meat, which method comprises mixing minced marine animal meat with a bicarbonate to adjust the pH of the meat to a value in the range of from 7.2 to 7.7 and mixing therewith an additive selected from the group consisting of common salt and sucrose fatty acid esters and kneading the mixture to convert the mixture into a meat paste, and contacting the meat paste with a hydrophilic organic solvent precooled to 0° to 5° C and in an amount sufficient to extract fat and water and drying the extracted meat to produce the proteinaceous food material.
Claim 5
Independent Claim
136 words
A method for the manufacture of a concentrated proteinaceous food material having properties suitable for the production of processed foodstuffs having a structure wherein an amorphous aggregate of meat protein is dotted with muscle fibers, resembling that of livestock meat, which method comprises mixing minced marine animal meat with a bicarbonate to adjust the pH of the meat to a value in the range of from 7.2 to 7.7 and mixing therewith an additive selected from the group consisting of common salt and sucrose fatty acid esters and kneading the mixture to convert the mixture into a meat paste, and contacting the meat paste with a hydrophilic organic solvent precooled to 0° to 5° C and in an amount sufficient to extract fat and water and drying the extracted meat to produce the proteinaceous food material.
Claim 6
Dependent Claim
23 words
The method according to claim 3, wherein said bicarbonate is one member selected from the group consisting of sodium bicarbonate and ammonium bicarbonate.
Claim 7
Dependent Claim
31 words
The method according to claim 3, wherein said additive is common salt added to the marine animal meat in an amount of 0.5 to 2% by weight based on said meat.
Claim 8
Dependent Claim
35 words
The method according to claim 3, wherein said additive is fatty acid ester of sucrose added to the marine animal meat in an amount of from 0.2 to 1% by weight based on said meat.
Claim 9
Dependent Claim
20 words
The method according to claim 3, wherein said meat paste is gelled and thereafter contacted with said hydrophilic organic solvent.
Claim 10
Dependent Claim
35 words
The method according to claim 7, wherein said gelling is carried out at normal room temperature for two to three hours or at a temperature lower than the room temperature for 10 to 48 hours.
Claim 11
Dependent Claim
30 words
The concentrated proteinaceous food material produced by the process of claim 1 and characterized by a protein content of at least 75% and a water content of 25% or less.
Claim 12
Dependent Claim
38 words
The food material obtained by mixing the concentrated food material of claim 9 with 3 to 5 times its weight of water and having a structure characterized by an amorphous aggregate of meat protein dotted with muscle fibers.
