The present disclosure provides a functional additive transferring (co)extruded thermoplastic food casing having a water vapor barrier and/or oxygen barrier effect wherein an inside surface of the thermoplastic food casing has a textured surface which forms a three-dimensional pattern of higher and lower retaining capacity for a functional additive.

A food product includes a first extruded component, a second extruded component co-extruded over the first component, the second component comprising a meat component and an additive, and a casing provided over the second component, wherein the additive comprises at least one of a flavoring, a seasoning, and a coloring.

The present invention is related to a food casing with antifungal properties comprising a coating formed by the application in at least its external surface of a water-based composition comprising at least, a film forming agent, a lipid and natamycin. The invention is also directed to the method for production of said food casing as well as to a meat product prepared by stuffing said food casing with meat or a meat emulsion.

The present invention relates to a multilayer film, especially to a multilayer thermoplastic film, which may be used for food packaging, wherein the multilayer film according to the present invention may be provided, on its inner side, with a food additive, particularly with a flavoring and/or coloring and/or an aroma producing food additive (such as e.g. a liquid smoke), which food additive is then released and transferred onto the surface of a foodstuff encased in the multilayer film during cooking and/or processing of the foodstuff.

The present invention provides a multi-layered coextruded thermoplastic food casing comprising: at least one thermoplastic porous absorbing layer; and at least one layer having a barrier effect for water vapor and/or oxygen, wherein the at least one layer having a barrier effect for water vapor and/or oxygen has an average layer thickness in a range of from 5 to 60 m over the entire surface area, wherein the at least one thermoplastic porous absorbing layer comprises as a main component at least one thermoplastic polymer material selected from the group consisting of (co)polyamides and (co)polyolefins, wherein the at least one thermoplastic porous absorbing layer comprises areas having a reduced average layer thickness and areas having a non-reduced average layer thickness, wherein the average layer thickness of the at least one thermoplastic porous absorbing layer in areas having a non-reduced average layer thickness is in a range of from 10 to 200 m, wherein the average layer thickness in areas having a reduced average layer thickness is lower by 7 to 140 m and is reduced by a range of from 30 to 85% compared to the areas having a non-reduced average layer thickness of the at least one thermoplastic porous absorbing layer, and wherein both areas having a reduced average layer thickness and a non-reduced average layer thickness comprise pores which are able to absorb a functional additive.

The present invention provides a functional additive transferring (co)extruded thermoplastic food casing having a water vapor barrier and/or oxygen barrier effect wherein an inside surface of the thermoplastic food casing has a textured surface which forms a three-dimensional pattern of higher and lower retaining capacity for a functional additive, wherein the thermoplastic food casing having a textured surface in case of a monolayer casing or an inner layer comprising the inside surface having a textured surface in case of a multilayer casing comprises as a main component at least one thermoplastic polymer material selected from the group consisting of (co)polyamides, (co)polyolefins, (co)polyester and vinylidenchloride (co)polymers, wherein the (co)extruded thermoplastic food casing does not comprise a net and/or a material forming a net or any other three dimensional structure on its outside surface, wherein the average thickness of the thermoplastic food casing in the areas having a higher retaining capacity is in a range of from 1 to 100 m, wherein the average thickness of the thermoplastic food casing in the areas having a lower retaining capacity is in a range of from 191 to 2000 m, provided that the thickness difference between the average thickness in the areas having higher retaining capacity and the average thickness in the areas having a lower retaining capacity is in a range of from 160 to 1950 m and that a ratio of the average thickness of the thermoplastic food casing in the areas having a higher retaining capacity and the average thickness of the thermoplastic food casing in the areas having a lower retaining capacity is in a range of from 0.002 to 0.25.

A device for applying liquid flavors to collagen casing is provided. In one embodiment, the device comprises a cup and a roller for applying liquid flavor to the surface of the collagen casing prior to drying. In another embodiment, the device comprises an applicator having a base plate with a first hole in the base plate to allow the collagen casing to pass through the base plate, a second hole in the base plate in fluid communication with the first hole to inject liquid flavor through the second hole into contact with the collagen casing as it passes through the first hole, a wiper removably attached to the base plate to wipe excess liquid flavor from the surface of the collagen casing, and a liquid flavor injection line attached to the second hole in the base plate. In some embodiments, the cup and roller are combined with the applicator to apply the liquid flavor.

A biopolymer-based food casing having an impregnation on the side facing the food is provided. The impregnation includes at least one hydrophobic, synthetic, organic polymer. By taloring the impregnation, the peelability of the casing may be adjusted to correspond to the type of food contained within the casing. The casing is used, especially, as an artificial sausage casing for raw sausage, scalded-emulsion sausage or cooked-meat sausage.

A method for producing collagen casings having one or more flavor ingredients incorporated into the collagen is provided. The flavor ingredients may be added during processing of collagen to produce the collagen casing; prior to, during or after drying of the collagen casing; prior to, during or after humidification to add moisture to the collagen casing; prior to, during or after shirring of the collagen casing; prior to or after the casing has been stuffed with meat products; during cooking of the stuffed collagen casing; and/or prior to packaging of the meat product. The flavor ingredient may be a water based flavor ingredient, an oil based flavor ingredient, a powdered flavor ingredient, a microencapsulated flavor ingredient, or a combination of two or more of these types of flavor ingredients. Collagen casings having one or more flavor ingredients incorporated into the collagen casing are also provided.

A food product includes a first extruded component, a second extruded component co-extruded over the first component, the second component comprising a meat component and an additive, and a casing provided over the second component, wherein the additive comprises at least one of a flavoring, a seasoning, and a coloring.
