casings from mold infestation. ## Claims ### Claim 1 A tubular cellulose-based food casing comprising a fungicidal coating or impregnation, wherein the coating or impregnation comprises one or more substances selected from the group consisting of carnosol, carnosic acid, rosemary oil, rosemary extract, sage oil and sage extract as a fungicidally active ingredient. ### Claim 2 (depends on 1) The food casing according to claim 1, wherein said coating or impregnation additionally comprises one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and gallates. ### Claim 3 (depends on 1) The food casing according to claim 1, wherein said coating or impregnation comprises an oily solvent. ### Claim 4 (depends on 3) The food casing according to claim 3, wherein said oily solvent is paraffin oil. ### Claim 5 (depends on 1) The food casing according to claim 1, wherein said coating or impregnation comprises a) carnosol and/or carnosic acid, and b) butylated hydroxyanisole and/or butylated hydroxytoluene. ### Claim 6 (depends on 1) The food casing according to claim 1, wherein said coating or impregnation is applied onto the food casing from the outside. ### Claim 7 (depends on 1) The food casing according to claim 1, wherein the percentage of the one or more substances selected from the group consisting of carnosol, carnosic acid, rosemary oil, rosemary extract, sage oil and sage extract is 0.01 to 3.5 weight percent, based on the dry food casing. ### Claim 8 (depends on 7) The food casing according to claim 7, wherein the percentage of the one of more substances is 0.02 to 0.7 weight percent based on the dry food casing. ### Claim 9 (depends on 7) The food casing according to claim 7, wherein the percentage of the one of more substances is 0.03 to 0.2 weight percent based on the dry food casing. ### Claim 10 (depends on 7) The food casing according to claim 7, wherein the percentage of the one of more substances is 0.04 to 0.15 weight percent based on the dry food casing. ### Claim 11 (depends on 2) The food casing according to claim 2, wherein the percentage of the one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and gallates is 0.01 to 3.5 weight percent, based on the dry food casing. ### Claim 12 (depends on 11) The food casing according to claim 11, wherein the percentage of the one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and gallates is 0.02 to 0.7 weight percent based on the dry food casing. ### Claim 13 (depends on 11) The food casing according to claim 11, wherein the percentage of the one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and gallates is 0.03 to 0.20 weight percent based on the dry food casing. ### Claim 14 (depends on 11) The food casing according to claim 11, wherein the percentage of the one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and gallates is 0.04 to 0.15 weight percent based on the dry food casing. ### Claim 15 (depends on 1) The food casing according to claim 1, wherein the percentage in weight percent, based on the dry food casing, of the one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and the gallates in proportion to the percentage in weight percent, based on the dry food casing, of the one or more substances selected from the group consisting of carnosol, carnosic acid, rosemary oil, rosemary extract, sage oil and sage extract lies between 1:10 and 10:1. ### Claim 16 (depends on 15) The food casing according to claim 15, wherein the percentage in weight percent, based on the dry food casing, of the one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and the gallates in proportion to the percentage in weight percent, based on the dry food casing, of the one or more substances selected from the group consisting of carnosol, carnosic acid, rosemary oil, rosemary extract, sage oil and sage extract lies between 1:5 and 5:1. ### Claim 17 (depends on 15) The food casing according to claim 15, wherein the percentage in weight percent, based on the dry food casing, of the one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and the gallates in proportion to the percentage in weight percent, based on the dry food casing, of the one or more substances selected from the group consisting of carnosol, carnosic acid, rosemary oil, rosemary extract, sage oil and sage extract lies between 1:2 and 2:1. ### Claim 18 (depends on 1) The food casing according to claim 1, wherein said coating or impregnation additionally comprises potassium sorbate and/or sodium sorbate and/or has a pH of 3 to 3.5. ### Claim 19 (depends on 1) The food casing according to claim 1, wherein said food casing is provided in a shirred form. ### Claim 20 (depends on 1) A sausage, comprising a food casing according to claim 1, and a sausage emulsion enclosed by said food casing. ### Claim 21 A method for protecting a food casing or a sausage product from mold infestation comprising coating or impregnating said food casing or said sausage product with one or more substances selected from the group consisting of carnosol, carnosic acid, rosemary oil, rosemary extract, sage oil and sage extract as a fungicidally active ingredient. ### Claim 22 (depends on 21) The method according to claim 21, wherein said one or more substances additionally comprises one or more substances selected from the group consisting of tocopherols, butylated hydroxyanisole, butylated hydroxytoluene and gallates. ### Claim 23 (depends on 21) The method according to claim 21, wherein said food casing is a cellulose-based food casing. ### Claim 24 (depends on 23) The method according to claim 23, wherein the cellulose-based food casing is a tubular cellulose-based food casing. ### Claim 25 (depends on 23) The method according to claim 23, wherein the cellulose-based food casing is
