Abstract
Abstract An extremely rapid, economical and safe method of producing dry sausages comprising adding natural bactericides and bacteriostats to comminuted meats in an amount sufficient to at least inhibit growth of the generally encountered pathogenic and non-pathogenic organisms in such meats, admixing a given amount of at least one acidulating material to such meats and forming sausages from such acidulated meats so that a pH of less than about 5.7 is attained within said sausages, thermally treating the sausages under time-temperature conditions sufficient to attain an average internal temperature within each sausage of at least about 58° C. and subjecting the thermally-treated sausages to a controlled drying environment having relatively high temperatures and relatively low relative humidity for a period of time sufficient to reduce the moisture level in each of such sausages to a maximum of approximately 35%. Stable, safe sausage products are attained within about 5 to 20 days after initiation of the process.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
177 words
A method of producing dry sausage comprising a combination of sequential substantially uninterrupted steps of: (a) adding a quantity of food-grade bactericides and bacteriostats to comminuted meats in an amount sufficient to at least inhibit growth of commonly encountered pathogenic and nonpathogenic organisms in said meats; (b) admixing a given amount of at least one chemical acidulating material to such meats and relatively promptly forming sausages from such acidulated meats so that a pH of less than about 5.7 is attained within said sausages; (c) thermally treating the so-formed sausages at time-temperature conditions sufficient to attain an average internal temperature within each sausage of at least about 58° C. within about 5 to 12 hours after initiation of step (a); and (d) subjecting the thermally treated sausages to a controlled drying environment having a relatively high temperature and a relatively low relative humidity sufficient to remove about 28 grains of water per pound of air for a period of time sufficient to reduce the moisture level in each of said sausages to a maximum of approximately 35%.
Claim 2
Independent Claim
177 words
A method of producing dry sausage comprising a combination of sequential substantially uninterrupted steps of: (a) adding a quantity of food-grade bactericides and bacteriostats to comminuted meats in an amount sufficient to at least inhibit growth of commonly encountered pathogenic and nonpathogenic organisms in said meats; (b) admixing a given amount of at least one chemical acidulating material to such meats and relatively promptly forming sausages from such acidulated meats so that a pH of less than about 5.7 is attained within said sausages; (c) thermally treating the so-formed sausages at time-temperature conditions sufficient to attain an average internal temperature within each sausage of at least about 58° C. within about 5 to 12 hours after initiation of step (a); and (d) subjecting the thermally treated sausages to a controlled drying environment having a relatively high temperature and a relatively low relative humidity sufficient to remove about 28 grains of water per pound of air for a period of time sufficient to reduce the moisture level in each of said sausages to a maximum of approximately 35%.
Claim 3
Dependent Claim
30 words
A method of producing dry sausages as defined in claim 1 wherein said bactericides and bacteriostats are selected from the group consisting of potassium nitrite, sodium nitrite and mixtures thereof.
Claim 4
Dependent Claim
35 words
A method of producing dry sausages as defined in claim 2 wherein the amount of bactericides and bacteriostats added to said comminuted meats is in the range of about 100 to 150 ppm of meat.
Claim 5
Dependent Claim
57 words
A method of producing dry sausages as defined in claim 1 wherein said acidulating material is selected from the group consisting of glucono delta lactone, lactic acid, acetic acid, phosphoric acid, maleic acid, citric acid, fumaric acid, tartaric acid, adipic acid, succinic acid, hydrochloric acids, anhydrides of such acids, edible salts of such acids, and mixtures thereof.
Claim 6
Dependent Claim
34 words
A method of producing dry sausages as defined in claim 4, wherein said acidulating material is selected from the group consisting of glucono delta lactone, lactic acid, acetic acid, hydrochloric acid and mixtures thereof.
Claim 7
Dependent Claim
53 words
A method of producing dry sausages as defined in claim 1 wherein said thermal treating of sausages includes subjecting said sausages, after they attain an average internal temperature of at least about 58° C., to a relatively brief hot water shower to remove any exuded material on the outer surface of said sausages.
Claim 8
Dependent Claim
60 words
A method of producing dry sausages as defined in claim 1 wherein said drying environment has a temperature in the range of about 18° to 24° C. and has a relative humidity in the range of about 50% to 65% so as to attain an average moisture removal rate from said sausages of at least about 2% per 24 hours.
Claim 9
Dependent Claim
39 words
A method of producing dry sausages as defined in claim 1 wherein the amount of acidulating material admixed with the meats is sufficient to impart a pH to sausages formed therefrom in the range of about 5.7 to 5.0.
Claim 10
Dependent Claim
35 words
A method of producing dry sausages as defined in claim 1 wherein said process is relatively continuous and yields a dry sausage product within about 5 to 20 days capable of prolonged non-refrigerated safe storage.
Claim 11
Dependent Claim
64 words
A dry sausage produced in accordance with the method defined in claim 1 and characterized by (a) a pH of about 5.7 to 5.0; (b) a maximum moisture content of approximately 35%; (c) a salt content of at least about 5%; (d) a nitrite content of not more than about 50 ppm and (e) a water activity level of not more than about 0.86.
Claim 12
Dependent Claim
62 words
A dry sausage product as defined in claim 10 wherein said product is characterized by (a) a pH of about 5.7 to 5.4; (b) a moisture content of approximately 30%; (c) a salt content of at least about 5%; (d) a nitrite content of not more than about 50 ppm and (e) a water activity level of not more than about 0.86.
