Abstract: The invention describes a process to produce a casing with marks and a meat product with marks. Said process starts from a casing by way of pleated tubular wrapping, where a coloring composition is impregnated on at least one sector of its surface to produce a casing with marks, which is optionally transferred to the stuffed meat product in said casing.

Abstract: The invention relates to a method for closing the end of shirred tubular casings which comprises deshirring a terminal portion of the tubular casing in the direction of the axis of the stick, turning over the deshirred terminal portion in order to insert same inside the casing, securing the deshirred terminal portion from inside the casing, rotating the terminal portion and flattening the rotated terminal portion. This method is performed at the outlet of the shirring line (ON-LINE) as an additional phase of said operation, or it is performed away from the deshirring line (OFF-LINE) as an operation independent from the deshirring.

Abstract: The present invention basically consists of printing proofing marks on a film, placing it in contact with a food product, followed by an intense drying at low relative moisture and a smoking step which also occurs at low relative moisture for obtaining areas having a more smoked color in the food product under the proofing marks than in the areas not protected by said proofing marks.

Abstract: The invention describes a process to produce a casing with marks and a meat product with marks. Said process starts from a casing by way of pleated tubular wrapping, where a colouring composition is impregnated on at least one sector of its surface to produce a casing with marks, which is optionally transferred to the stuffed meat product in said casing.

Abstract: The present invention relates to an artificial casing for the preparation of stuffed meat products which comprises a reducing sugar, capable of providing a pleasant golden brown colour to said stuffed meat product once heat treated. Likewise, the invention relates to a process to produce said artificial casings, the meat products produced as well as the production process thereof.

Abstract: The invention seeks to obtain a collagen film with improved extensibility characteristics, preventing or diminishing the structural rigidity of collagen films of this kind. This purpose is achieved by providing such collagen with an oily additive, such as oils or fats, thereby rendering such films suitable to be used in ham stuffing machines. This beneficial effect is obtained when the addition of oily additives lies between 1 and 60% of the collagen contents measured as a dry extract of the film.
