The present invention relates to a method for co-extruding an elongated food product wherein the method comprises measuring the product characteristics of the viscous gelling agent provided and wherein the physical state of the collagen is controlled by balancing the process settings of the at least one subsequent processing step based upon the product characteristics measured.

The present invention relates to a method for preparing food products by means of processing food particles with a gelling agent, comprising the processing steps of: a) providing a food particles; b) providing a viscous gelling agent; c) treating the viscous gelling agent with an acidic buffer solution; and d) bringing at least a part of the food particles in contact with the viscous gelling agent. The present invention further relates to a device for performing this method, to the obtained food product and the use of an acidic buffer solution for stabilizing food products.

The present invention relates to a method and production line for in-line processing of food products. The method comprises the step of co-extruding a food dough into a flow of co-extruded food products having a casing that comprises a protein, or a hybrid casing of a protein and a polymer, wherein the method subsequently comprises the successive steps of: a) subjecting the flow of co-extruded food products to a surface treating step, b) subjecting the flow of food products to a thermal treating step, and c) optionally, subjecting the thermally treated flow of food products to a post-thermal treating step, wherein in step b) the flow of food products is at least subsequently subjected to a first thermal treating step, and a second thermal treating step.

The invention relates to a method for preparing a food product by means of co-extrusion, where a casing composition and a barrier composition are co-extruded as layers upon an edible filler, such that the edible filler is provided with a casing layer and a barrier layer. After co-extrusion, the barrier layer is present between the edible filler and the casing layer. Advantageously, the casing composition includes collagen, a polysaccharide and water. Further, the invention relates to a food product. The food product, for instance a sausage, includes an edible filler, a casing layer, and a barrier layer, where the edible filler is covered by the barrier layer at least partly, and where the barrier composition is coverer by the casing layer at least partly.

The present invention relates to a method for preparing food products by means of extrusion, comprising the processing steps of: i) providing a food dough; ii) providing a viscous coating agent; iii) extruding a strand of food dough and extruding a coating layer at least partially enclosing the strand; iv) treating the at least partially coated strand with a liquid strengthening agent during at least two strengthening steps such that the coating layer of the strand is strengthened; to a device for performing this method and to the obtained food strand.

The invention relates to an edible tubular collagen film which has a closure at either of their ends. The closure is formed by an edible solid ring-like element which tightens the end portion of casing and seals the outlet of the same, in order to stop the filling mass upon beginning of a sausage stuffing process, whereby in such a process one can rescue the initial filled sausage for its further processing, whereafter the ring disappears. This edible closing element is characterized by being of an edible, and thermoplastic composition, which is preferably based on collagen or gelatine. The solid composition has a low melting temperature and becomes adhesive at fluid state onto the surface of a collagen film which contains a certain level of moisture. The strong cohesiveness of the material of said composition in the fluid state as well as the so narrow difference between its melting temperature and the temperature of solidification, makes that a welding of said material to be set very quickly. The closure can be made before or after the shirring of the collagen casing and the present invention provides also a process to perform such a closure by heat welding the closing element on the casing material.

The present invention relates to a tube-removing machine and method of manufacturing artificial casings by means of said machine, allowing a fast, efficient and automatic cutting of the sections of casing (2) which contain tubes (5), subsequently splicing the remaining casing (2) once said tube (5) is discarded, comprising detection means (10) for detecting the arrival of a tube (5) contained in the casing (2); cutting means (20) for cutting a section of the casing (2) incorporating said tube (5); splicing means (30) for splicing the ends of the cut casing (2); and temporary storage means (40) for storing the casing (2) which allow continually taking in casing (2) in the tube-removing machine (1) during the time used in the cutting and splicing phases, preventing interruptions in the subsequent shirring process.

The invention relates to a device (1) for producing a case having a large length for food, in particular for sausages, from a plurality of individual case sections made of casings that contain collagens, such as natural casings or collagen-containing artificial casings, comprising a mandrel (2) and at least two sleeve sections (3), wherein the sleeve sections (3), in order to create an overlapping area (4), are pushed over the mandrel (2) and arranged such as to overlap each other, a heating element (5) for temporarily exchanging heat between the heating element (5) and the overlapping area (4), such that the case sections are at least partially welded to each other in the overlapping area (4), a deformable extension body (6), wherein the deformable extension body annularly surrounds the mandrel (2) and is arranged inside the case sections (3), wherein the deformable extension body (6) is made of an elastically deformable material, and a mold (7) that encloses the mandrel (2) in some sections.

The present invention relates to a tube-removing machine and method of manufacturing artificial casings by means of said machine, allowing a fast, efficient and automatic cutting of the sections of casing (2) which contain tubes (5), subsequently splicing the remaining casing (2) once said tube (5) is discarded, comprising detection means (10) for detecting the arrival of a tube (5) contained in the casing (2); cutting means (20) for cutting a section of the casing (2) incorporating said tube (5); splicing means (30) for splicing the ends of the cut casing (2); and temporary storage means (40) for storing the casing (2) which allow continually taking in casing (2) in the tube-removing machine (1) during the time used in the cutting and splicing phases, preventing interruptions in the subsequent shirring process.

In a device for manufacturing co-extruded food products with a filling machine, including a pump for an inner mass coupled to a drive and a control unit at least for the drive, to which a coextrusion unit disposed at the outside is connected, and to which a pump being coupled to a drive at least for delivering the outer mass to the coextrusion unit is connected. The drive of the outer mass pump is integrated into the inner mass filling machine.
