A system for producing food product may include an inner tube configured to extrude a first component, and an outer tube provided about the inner tube to define an annular space through which a second component is extruded, the inner and outer tubes, alone or in conjunction with a nozzle or other extrusion mechanism, defining an outlet. Additionally, a collagen head can be configured to apply a layer of collagen gel over the second component. The inner and outer tubes are sized, and flow rate may be configured such that an initial diameter of the first component exiting the outlet is substantially smaller than a final diameter of the first component, and an initial thickness of the second component exiting the outlet is substantially greater than a final thickness of the second component.

A low profile water bath co-extrusion process for sausage manufacturing is disclosed, along with machines for accomplishing this process. The process is an automated assembly line which begins with co-extruded food product, such as a sausage emulsion coated with collagen and finishes with cooked, boxed, packaged link sausage. The process includes the steps of co-extrusion, linking and cutting the co-extruded food product to individual links. Following these steps and prior to a liquid smoking step, the casing is prepared by steps which includes chemical treatment of the individual links in a water bath, while dehydrating the product in a salt solution, the water bath being a two-part process and following the water bath using a forced hot air drying step. Machines disclosed include a modification of prior art screw driven water bath and a novel roller/conveyor forced hot air drying assembly that subjects individual links of a co-extruded food product to a rolling motion while simultaneously being transported horizontally and being subject to forced hot air drying.

A coextruded, multi-layered, water vapor-impermeable, tubular, and seamless food casing having at least three layers is provided. The layers include at least one porous layer having a porous food contact side suitable for transferring food additives having a porous food contact side, at least one carrier layer based on at least one aliphatic and/or partially aromatic (co-)polyamide, and at least one water vapor-impermeable layer. At least one adhesive layer including an adhesion-promoting component is arranged between the adjoining layers or an adhesion-promoting component is contained in one or more of the water vapor-impermeable layer(s). At least one porous layer includes an aliphatic (co-)polyamide and a hydrophilic (co-)polymer having a mean molar mass M.sub.w of at least 8000 Da. A method for producing the food casing is provided. The food casing is used as an artificial sausage casing, especially, for cooked or boiled sausage.

This invention relates to an alginate composition for coating food products, in particular cooked meat products such as sausages and a method for producing the alginate composition. Furthermore, the invention relates to a method for producing coated food products with the use of the alginate composition of the invention.

A machine including a supply of gelling agent (45), a supply of acidic buffer solution (47), a third supply of food inlet (51) connected to a source of food (53), a mixer (27) connected to the gelling agent and acidic buffer solution supplies, for delivering a mixture of gelling agent and acidic buffer solution, and a co-extruder (31) fed with food (51) and with said mixture, for extruding the food at the center and the mixture at the periphery, so as to obtain the expected food product at the outlet.

The present invention relates to a method for manufacturing sausage products by means of co-extrusion, wherein the method comprises the following steps of: A) providing a food dough; B) providing a viscous paste; C) producing by means of co-extrusion a sausage strand with a core of the food dough enclosed by a casing of the paste; D) subdividing the sausage strand into sausage products; and E) guiding the sausage through a fixing bath, whereby the cohesion of the sausage increases.

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 invention relates to a method for manufacturing sausage products by means of co-extrusion, wherein the method comprises the steps of: providing a food dough (6); providing a viscous casing mass material (8); and producing by means of co-extrusion a sausage strand (2) with the extrusion of a centre of food dough at least partially provided by layered casing mass material.

A system and method for processing a coextruded meat product including a casing enclosing a meat batter after brining in which a heated, high velocity air stream is applied to the coextruded meat product thereby mechanically removing moisture from a surface of the casing and cooking the coextruded meat product. This system and method can further improve the ability for a liquid coating to be added to the coextruded meat product in a non-drenching manner because of the superior surface preparation of the casing by the jets.
