Abstract
Abstract This invention provides a method of producing dehydrated meat products wh more easily and completely rehydrate than prior art dehydrated meats. This is accomplished by expansion of the cooked meat matrix by the addition of water, salt, phosphate and adjunctive hydrophilic ingredients prior to cooking. This invention is intended for use with formed meats consisting of a combination of chunked, flaked and ground or emulsified meats. The use of a gas and moisture impermeable casing for cooking the meat allows the meat to be fully cooked without concurrent losses in either weight or volume, thus preventing density increase prior to dehydration.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
276 words
A method for producing freeze dried cooked meats which are more easily and completely rehydratable, comprising the steps of: a. trimming a quantity of raw solid meat of heavy connective tissue and excess fat; b. grinding or emulsifying a first portion of said trimmed meat and flaking or chunking a second portion of said trimmed meat into flakes or chunks which are 2.5-6.0 cubic inches in volume; c. mixing said ground or emulsified first portion and said flaked or chunked second portion with about 2.0% to about 6.0% of the formula weight water, about 0.5% to about 2.0% of the formula weight salt, about 0.1% to about 0.5% of the formula weight phosphates and about 0.5% to about 5.0% of the formula weight an adjunctive hydrophilic ingredient until sufficient myofibrillar proteins are extracted to render the mixture moderately tacky and continuing said mixing until the water, salt, phosphates and adjunctive hydrophilic ingredients equilibrate throughout said mixture; d. preparing a meat log by tightly stuffing said mixture into a moisture and gas impermeable container, wherein said container is a casing comprising a fibrous cellulose exterior laminated onto a saran film interior, said casing fitting tightly to the surface of said meat so as to keep moisture in equilibrium within said meat product during cooking; e. cooking said meat log at a predetermined temperature for sufficient time to achieve a predetermined product center temperature; f. freezing said meat log; g. slicing or dicing said meat log into portions suitable for freeze dehydration; h. freeze vacuum dehydrating said portions to a predetermined moisture level; and i. packaging said dehydrated meat in an airtight container in the absence of oxygen.

Claim 3
Dependent Claim
77 words
The method as described in claim 1 wherein said salt is selected from the group consisting of sodium chloride and potassium chloride; said phosphate is selected from the group consisting of the salts of sodium pyrophosphate, orthophosphate, hexametaphosphate and tripolyphosphate and the adjunctive hydrophilic ingredients are selected from the group consisting of sodium carboxymethyl cellulose, microcrystalline cellulose, gum arabic, polyvinylpyrrolidone, arabino gallactan, xantham gum, kayara gum, guar gum, gum tragacanth, locust bean gum, malto dextrins and hydrocolloids.
Claim 4
Dependent Claim
53 words
A meat product prepared in accordance with the process of claim 1 wherein said meat product has an expanded matrix as a result of the mixing of the meat with water, salt, phosphates and adjunctive hydrophilic ingredients and said meat product rehydrates completely within 8 minutes upon being placed in 180° F. water.
