Artificial casings and process for their manufacture

The invention relates to artificial casings that are used as a replacement for thick-fleshed natural intestines, such as horse intestines, ox fat ends and pork fat endsj also called slag, able to serve.

It is known to pass natural casings, such as beef midgut Replace artificial casings. A type of the well-known artificial casings fce consists of a textile fabric scaffolding material, as a rule wide-meshed silk gauze with a square meter weight in the order of about 8 g, or even one Fabric mixture of rayon and silk with an only slightly higher quadrant weight, that with an extract or decoction of meat or skin substance, a pulp of minced fresh meat, minced skin or gelatine, glue, or glue and paste-like material is also impregnated. Impregnation is becoming more common wise up by soaking, pouring over or brushing ^

brought and then dried. As a result of the wide-meshed network of the tissue threads, in which the thread-free spaces make up approximately 90 to 95 % of the tissue area, these known artificial casings have only a comparatively weak mechanical strength and also have the disadvantage that they do not exactly follow the movements of the sausage mass, that is to say that they can neither adequately follow the filling pressure of the sausage mass at the beginning of the sausage preparation nor the contraction of the sausage during drying.

If a fabric such as gauze is used for these known artificial casings, used in close-meshed form and impregnated or coated with a meat mass minced to a pulp has been, an artificial casing could be obtained that does not burst due to the filling pressure of the sausage mass and when Drying the sausage mass does not wrinkle, but does This artificial casing has the disadvantage that it is sensitive to moisture and Air is impermeable and therefore not breathable, so that the sausage is in danger of suffocating. There are also sausage casings known for a long time under the name linen bags, which consist exclusively of Textile fabrics are made. To make these linen bags a fabric is used that is mechanically stronger and has a heavier square meter than silk gauze and gauze. However, these known sausage casings have the disadvantage that they have an unsightly gray appearance due to the air pockets present in the fabric, in particular

take on a dirty appearance as a result of smoke. aside from that a sausage filled in such casings tends to be easily attacked by mold or to have a visible coating to form, since juice and fat can pass through such a shell, and not protected by any outer layer are. This infestation, like surface dirt, cannot be removed by wiping or washing off.

The invention is based on the object of artificial casings in Proposal to bring the those previously described. Do not have disadvantages and are also suitable instead of thick-fleshed natural casings, for example for high-quality raw sausage, where the sausage is juicy and long to be kept fresh, to be used.

This object is achieved by means of the artificial casing according to the invention, which consists of a combination of textile material and animal substance and is characterized in that the textile material is an absorbent cotton material made of weft and warp with a thread count of 15 to 25 per cm and a square meter weight of more than JO g and as animal substance a swellable, fibrous, breathable collagen-based coating with a square meter weight of 15 to 30 g and these are arranged as a two-layer ® laminate with the cotton fabric layer on the inside and the fiber layer on the outside.

It has been found that particularly good results are achieved with an artificial casing in which a nettle fabric with a weight per square meter of 50 tts150g is present as the textile material, and which has a fiber-containing _, swellable, breathable coating with a water absorption capacity of 150 to 250 %, based on it Dry weight, has o The coating can be applied from a swelling material with a dry content of about 3 # obtained from cattle crevice with gentle treatment with lime and acid; a coating made of viscose can also be provided. Λ

The artificial casings according to the invention can contain considerable amounts of liquid and have the following advantages over known synthetic casings:

- The strength surpasses all so far on an artificial casing demands made by the industry!

- the fine collagen coating enables an excellent Breathable and smoke acceptance of the sausage and thus a quick maturation of long-life sausages

- In contrast to the well-known artificial casings, the absorbent inner textile layer picks up meat juice and fat after the synthetic casing has been filled with sausage mass and forms a protective layer on the inner wall, which works in a similar way to fatty intestines and makes the sausage longer when stored fresh * kept *

The artificial casings according to the invention can expediently be manufactured in such a way that on one side of an absorbent cotton fabric, for example nettle, with a weight per square meter of more than 30 g, a swelling of collagen fiber as obtained mass, expediently with a dry weight of about 3 % * in a layer thickness corresponding to a square meter weight of 15 to 30 g is applied, the two-layer laminate thus obtained is dried, cut into the desired blanks and then joined together to form tubes with the fiber coating facing outwards. It is also possible, and this will often be more expedient in practice, first of all to divide the fabric web into strips and to make these strips in the form of a tube Apply the seam 10 mm away from the edge lying one above the other.
