OWENS; Wayne LARSON - Web page: https://patentgrep.com/patent/US20140154375A1 ## CPC - A23L 13/20: from offal, e.g. rinds, skins, marrow, tripes, feet, ears or snouts (glands or bones as ingredients of processed meat A23L13/60) - A23L 5/49: Removing colour by chemical reaction, e.g. bleaching - A23L: FOODS, FOODSTUFFS OR NON-ALCOHOLIC BEVERAGES, NOT OTHERWISE PROVIDED FOR; PREPARATION OR TREATMENT THEREOF (preservation thereof A23B) ## Abstract A method for processing tripe includes refining tripe with at least one bleaching agent and at least one alkaline material to improve tripe appearance, and contacting the treated tripe with an alkaline builder at a temperature of about 110° F. to 160° F. Tripe may be rinsed with cold water before packaging. The methods of processing tripe may provide tripe with enhanced appearance appealing to consumers, while increasing margin profits to meat packing plants due to higher tripe yield and lower operation cost. ## Claims ### Claim 1 A method for processing tripe, comprising: contacting the tripe with at least one bleaching agent and at least one alkaline material for a period of time sufficient to bleach the tripe; contacting the tripe with an alkaline builder at a temperature of at least about 110° F.; and contacting the tripe with cold water having a temperature below about 40° F. ### Claim 2 (depends on 1) The method of claim 1, wherein contacting the tripe with an alkaline builder at a temperature of at least about 110° F. comprises contacting the tripe with an alkaline builder at a temperature of from about 110° F. to about 160° F. ### Claim 3 (depends on 1) The method of claim 1, wherein contacting the tripe with an alkaline builder comprises contacting the tripe for a sufficient period of time to raise the surface pH of the tripe to from about 12.2 to about 12.8. ### Claim 4 (depends on 1) The method of claim 1, comprising: contacting the tripe with at least one bleaching agent and at least one alkaline material at a temperature of about 120° F. to about 145° F. for a period of time sufficient to bleach the tripe to desired tripe whiteness; and contacting the tripe with an alkaline builder for a sufficient period of time to raise a surface pH of the tripe to about at least 12.5. ### Claim 5 (depends on 1) The method of claim 1, wherein the bleaching agent is present in an amount from about 0.1% to about 0.5% on an active available oxygen basis based on tripe weight. ### Claim 6 (depends on 1) The method of claim 1, wherein the bleaching agent is present in an amount from about 0.2% to about 0.3% on an active available oxygen basis based on tripe weight. ### Claim 7 (depends on 1) The method of claim 1, wherein the alkaline material is in an amount from about 0.05% to about 0.2% alkaline material reported as equivalent to Na2O active basis based on tripe weight. ### Claim 8 (depends on 1) The method of claim 1, wherein the alkaline material includes a member selected from the group consisting of sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide, trisodium phosphate, sodium metasilicate, and combinations thereof. ### Claim 9 (depends on 1) The method of claim 1, wherein the alkaline builder includes a member selected from the group consisting of sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide, trisodium phosphate, sodium metasilicate, and combinations thereof. ### Claim 10 (depends on 1) The method of claim 1, wherein contacting the tripe with an alkaline builder further comprises contacting the tripe with a bleaching agent. ### Claim 11 (depends on 1) The method of claim 1, where the cold water has a temperature of about 32° F. to 35° F. ### Claim 12 (depends on 1) The method of claim 1, wherein contacting the tripe with the cold water comprises contacting the tripe with cold water for about 1 to about 2 minutes. ### Claim 13 (depends on 1) The method of claim 1, wherein the tripe includes at least one of scalded tripe and honeycomb tripe. ### Claim 14 (depends on 1) The method of claim 1, comprising contacting the tripe with an alkaline builder is performed for a duration of from about 2 minutes to about 7 minutes. ### Claim 15 (depends on 1) The method of claim 1, characterized by an automatic process. ### Claim 16 A method for processing tripe, comprising: washing the tripe with water at a temperature of at least 120° F.; treating the tripe with at least one bleaching agent and at least one alkaline material to bleach the tripe to desired tripe whiteness; contacting the tripe with an alkaline builder to raise a surface pH of the tripe to about 12.5; and contacting the tripe with cold water before packaging. ### Claim 17 (depends on 16) The method of claim 16, where the cold water has a temperature below about 40° F. ### Claim 18 (depends on 16) The method of claim 16, where the cold water has a temperature of from about 32° F. to 35° F. ### Claim 19 (depends on 16) The method of claim 16, wherein contacting the tripe with the cold water comprises contacting the tripe with cold water for about 1 to about 2 minutes. ### Claim 20 (depends on 16) The method of claim 16, wherein contacting the tripe with an alkaline builder further comprises contacting the tripe with a bleaching agent. ### Claim 21 (depends on 16) The method of claim 16, wherein the tripe is contacted with an alkaline builder for about 1 to about 5 minutes. ### Claim 22 (depends on 16) The method of claim 16, wherein contacting the tripe with the cold water comprises contacting the tripe with cold water until the temperature of the tripe is less than 65° F.
