Abstract
Abstract This invention relates to a method of forming a fish product and particularly a product resembling a grated 100 percent tuna product from tuna flesh and synthetic protein filaments. The protein filaments are chopped to lengths of about 0.125 - 0.375 inches prior to being blended with tuna flesh and the liquid content (oil or water) of the protein filaments is controlled within the critical range of 75 - 85 percent prior to or as they are being blended with the tuna flesh. The mixture may then be passed through a grating machine or the protein filaments may be blended with the tuna after the tuna has been grated. The mixture is then placed in a can and retorted to form a product substantially resembling a grated 100 percent tuna product in texture and consistency.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
104 words
A METHOD OF FORMING A GRATED TUNA-TYPE PRODUCT FROM TUNA FLESH AND PROTEIN FILAMENTS COMPRISING THE STEPS OF: PREPARING HEAT SETTABLE SYNTHETIC PROTEIN FILAMENTS, CHOPPING THE HEAT SETTABLE FILAMENTS INTO DISCRETE PARTICLES, SUBSTANTIALLY ALL OF WHICH HAVE A LENGTH OF LESS THAN ABOUT 3/8 INCHES, ADJUSTING THE LIQUID CONTENT OF THE DISCRETE PARTICLES TO ABOUT 75-85 PERCENT BY WEIGHT AND FORMING A MIXTURE OF SAID ADJUSTED PARTICLES WITH TUNA FLESH, THE DISCRETE PARTICLES BEING PRESENT IN A RANGE FROM 1-60 PERCENT BY WEIGHT OF THE MIXTURE; GRATING THE MIXTURE, PLACING THE GRATED MIXTURE INTO CANS AND RETORTING THE MIXTURE TO PROVIDE A TUNA-TYPE PRODUCT.
Claim 2
Independent Claim
104 words
A METHOD OF FORMING A GRATED TUNA-TYPE PRODUCT FROM TUNA FLESH AND PROTEIN FILAMENTS COMPRISING THE STEPS OF: PREPARING HEAT SETTABLE SYNTHETIC PROTEIN FILAMENTS, CHOPPING THE HEAT SETTABLE FILAMENTS INTO DISCRETE PARTICLES, SUBSTANTIALLY ALL OF WHICH HAVE A LENGTH OF LESS THAN ABOUT 3/8 INCHES, ADJUSTING THE LIQUID CONTENT OF THE DISCRETE PARTICLES TO ABOUT 75-85 PERCENT BY WEIGHT AND FORMING A MIXTURE OF SAID ADJUSTED PARTICLES WITH TUNA FLESH, THE DISCRETE PARTICLES BEING PRESENT IN A RANGE FROM 1-60 PERCENT BY WEIGHT OF THE MIXTURE; GRATING THE MIXTURE, PLACING THE GRATED MIXTURE INTO CANS AND RETORTING THE MIXTURE TO PROVIDE A TUNA-TYPE PRODUCT.
Claim 3
Dependent Claim
21 words
The method according to claim 1 wherein the protein filaments are about 15 - 45 percent by weight of the mixture.
Claim 4
Dependent Claim
25 words
The method according to claim 1 wherein substantially all of the discrete particles of protein filaments have a length of approximately 1/8 - 3/8 inches.
Claim 5
Independent Claim
101 words
A method of forming a food product from tuna flesh and protein filaments comprising the steps of: preparing heat settable synthetic protein filaments, controlling the liquid content of the filaments within the range of about 75 - 85 percent by weight, chopping the heat settable filaments into discrete particles substantially all of which have a length of less than 3/8 inches, forming a mixture of said discrete particles with tuna flesh in a range from 1-60% by weight of the mixture, grating the mixture, placing the grated mixture into a can and retorting the mixture to form a grated tuna-type product.
Claim 6
Independent Claim
101 words
A method of forming a food product from tuna flesh and protein filaments comprising the steps of: preparing heat settable synthetic protein filaments, controlling the liquid content of the filaments within the range of about 75 - 85 percent by weight, chopping the heat settable filaments into discrete particles substantially all of which have a length of less than 3/8 inches, forming a mixture of said discrete particles with tuna flesh in a range from 1-60% by weight of the mixture, grating the mixture, placing the grated mixture into a can and retorting the mixture to form a grated tuna-type product.
Claim 7
Dependent Claim
21 words
The method according to claim 4 wherein the protein filaments are about 15 - 45 percent by weight of the mixture.
Claim 8
Independent Claim
135 words
A method of forming a grated tuna-type product from tuna flesh and protein filaments comprising the steps of: preparing heat settable synthetic protein filaments, chopping the heat settable filaments into discrete particles substantially all of which have a length of less than 3/8 inches, forming a mixture of said discrete particles with tuna flesh which has been grated while adding sufficient liquid to adjust the liquid content of the discrete particles to about 75 - 85 percent by weight with a minimum of approximately 45 percent by weight of the filaments being supplied by water, the discrete particles being present in a range from 1-60 percent by weight of the mixture, placing the mixture into a can and retorting the mixture to form a grated tuna-type product which has a texture which readily breaks apart.
Claim 9
Independent Claim
135 words
A method of forming a grated tuna-type product from tuna flesh and protein filaments comprising the steps of: preparing heat settable synthetic protein filaments, chopping the heat settable filaments into discrete particles substantially all of which have a length of less than 3/8 inches, forming a mixture of said discrete particles with tuna flesh which has been grated while adding sufficient liquid to adjust the liquid content of the discrete particles to about 75 - 85 percent by weight with a minimum of approximately 45 percent by weight of the filaments being supplied by water, the discrete particles being present in a range from 1-60 percent by weight of the mixture, placing the mixture into a can and retorting the mixture to form a grated tuna-type product which has a texture which readily breaks apart.
Claim 10
Dependent Claim
21 words
The method according tO claim 6 wherein the protein filaments are about 15 - 45 percent by weight of the mixture.
Claim 11
Dependent Claim
25 words
The method according to claim 7 wherein substantially all of the discrete particles of protein filaments have a length of approximately 1/8 to 3/8 inches.
