Definitions

  • This invention relates to an improved meat casing, and in particular to a meat casing having a particular type of knit in combination with circumferential elastic reinforcement to produce a substantially transparent casing.
  • Meeat product any fresh or processed meat product.
  • natural or artificial casings in the form of elongated tubes are normally pumped full of meat from a machine specifically designed for the purpose.
  • a machine normally comprises a feed mechanism for injecting meat through a delivery tube or injection horn, where the casing is shirred to the external surface of the delivery tube.
  • a clip or other closure means is placed over the ends of the casing, and a quantity of meat is then injected into the casing.
  • the process is interrupted at various stages so that clips or twists may be applied.
  • circumferential elastic members which are incorporated into a knitted fabric tube.
  • the circumferential reinforcing cords are placed under tension as the casing is filled, and the strength of the cords and the knitted material provides sufficient strength to withstand bursting.
  • Knitted material produces a stretch fabric and it is possible to produce a fabric that is sufficiently close in knit to cause retention of both meat products and fluid or juices contained within the meat. Although the weave is sufficiently tight to cause a fluid barrier, the material is still gas permeable and therefore allows conventional curing or smoking of the product.
  • the above-described casing is extremely useful, it results in the meat product having an opaque casing on its outer surface. In some instances, this is quite acceptable, as the casing is removed from the meat product subsequent to the cooking or curing process. However, it would be an advantage if a casing were able to be substantially transparent so that it could be left on the meat product.
  • the invention comprises a tubular casing comprising a knitted tube, produced in continuous lengths, with circumferential elastic cords incorporated therein, the invention being characterised by the use of a stitch in the knitting process which results in a very open knitted fabric when the casing is filled and the fabric is stretched.
  • the knitting process uses a loop-style stitching which results in a greater than 50% open area when the stitch is fully extended. This results in a substantial portion of the meat surface being exposed which results in a substantially transparent appearance for the casing. Therefore, when the casing is on the meat product, the circumferential elastic reinforcement members will be clearly visible, but the area between the circumferential cords will be substantially transparent.
  • translucent monofilament or multifilament yarns are used which further assist in producing a translucent effect. They also have the advantage of being non-absorbent.
  • an important aspect of the invention is to produce an open knitted stitch which results in the transparent appearance.
  • a further advantage is the minimal surface contact between the casing and the meat product and the use of synthetic non-absorbent yarn, which both result in a reduced tendency for the casing to stick to the meat product. Accordingly, the invention meets the two main objectives. Nevertheless, there will be surface contact between any exuded moisture and/or fat content from the meat product and the filaments of the casing. The moisture and/or fat will tend to coat the filaments of the casing, thus augmenting the transparent effect, yet without the filaments being embedded in the surface of the meat product.
  • the diameter of the circumferential reinforcing cords is significantly less in the relaxed state prior to filling than at the maximum filled diameter of the casing. This results in the elastic cords providing a compression effect around the meat product placed within the casing, which produces a pleasing decorative effect along the surface of the meat product. It also ensures that sufficient compressive force is applied to the meat product to reduce air pockets within the meat as it shrinks during the cooking or curing process.
  • the invention will also include the use of longitudinal reinforcement members in combination with the circumferential members.
  • the longitudinal members may also be also elastic, or may comprise inextensible longitudinal cords.
  • the circumferential or longitudinal members may be knitted either on the internal surface or external surface of the casing.
  • the reinforcement cords being located on the external surface of the casing, there will be a decreased tendency for the cords to adhere to the meat surface.
  • Fig. 1 shows a portion of a tubular casing according to a first embodiment of the invention
  • Fig. 2 is a close-up view of the pattern of threads in this first embodiment
  • Fig. 3 is a close-up view of a portion of the tubular casing according to this first embodiment when it has a food product located within to the extent that the circumferential elastic reinforcement members become inextensible, producing a decorative effect along the surface of the food product;
  • Fig. 4 is a close-up view of a filled casing according to a second embodiment of the invention, where the casing further comprises longitudinal reinforcement members.
  • a tubular casing 10 comprises a tubular knitted portion 11 and circumferential elastic reinforcement members 12.
  • the material used for tubular portion 11 is a translucent polyester thread, and circumferential members 12 are formed from elasticated threads.
  • Tubular portion 11 is produced by a knitting process.
  • a jersey knit is used, and the circumferential members 12 are on the inside of tubular casing 10.
  • the elasticated thread of circumferential members 12 is attached to the internal surface of tubular portion 11 by tuck stitches 13 and, in this embodiment, the elasticated thread is preferably bound in a cotton thread.
  • the elastic circumferential thread 12 may form separate rings, as shown, or statistical iternatively form a spiral along the length of tubular portion 11. When the tubular casing 10 is being filled with a meat product, the circumferential threads 12 will begin to impress against the surface of the meat product while the tubular knitted portion 11 is still quite stretchable.
  • the circumferential threads 12 embedding or forcing their way into the surface of the meat product whereupon the meat product protrudes as a result of tubular portion 11 still being stretchable.
  • the circumferential threads 12 form a distinctive surface pattern.
  • the circumferential threads 12 are embedded into the surface of the meat product, whereas the meat product protrudes within each of the bands 14. This results in the distinctive surface pattern being applied to the meat product.
  • circumferential threads 12 and longitudinal threads 15 are securely stitched to tubular portion 11 at points of intersection of the circumferential and longitudinal threads 12 and 15, by means of tuck stitches.
  • longitudinal threads 15 are formed from a plurality of interengaging loops.
  • the thread that forms the longitudinal thread 15 extends along and is secured to the elastic circumferential thread 12, whereupon it reaches a predetermined point and a loop is formed.
  • the loop is extended downwardly and locates around the base of a lower loop and then extends upwardly whereupon it again extends along the elastic circumferential thread 12.
  • the elastic circumferential thread 12 is formed as a continuous spiral
  • the longitudinal thread 15 may be formed as the knitting of tubular portion 11 and placement of the elastic circumferential thread 12 progresses.
  • the use of the loop stitch form to produce the longitudinal threads 15 means that there is a degree of movement of the stitch before it is stretched to its limit.
  • tubular casing 10 is able to expand longitudinally as well as circumferentially before the longitudinal elastic threads 15 begin to impress against the surface of the meat product. Both the longitudinal threads 15 and the circumferential threads 12 are drawn deeply into the surface of the meat product. This results in an extensive quilting pattern, as shown in Fig. 4, with the food product forming outward bulges 16 between the grid formed by the longitudinal and circumferential threads.
  • the invention described in accordance with these embodiments is capable of being used in either a cooking or curing process, with respect to meat and other food products. It has been found that the tubular casing 10 is readily removed from the surface of the food product when it has been cooked or cured. This results in the desired surface pattern remaining on the food product.

Abstract

L'invention concerne une enveloppe tubulaire (10) conçue pour être placée autour d'une denrée alimentaire (en particulier un produit à base de viande) avant la cuisson ou la salaison. Cette enveloppe présente un aspect pratiquement transparent lorsque la denrée alimentaire est placée à l'intérieur. Elle comprend une partie tubulaire à mailles (11) réalisée en longueur continue à partir de fil transparent, la paroi de cette partie tubulaire à mailles (11) présentant un motif à mailles de type boucles extensibles permettant d'obtenir une surface ouverte supérieure à 50 % lorsque les boucles sont entièrement étirées. Cette paroi est cependant pratiquement imperméable à la denrée alimentaire. Cette enveloppe comprend également des fils élastiques (12) de renforcement circonférentiels fixés de façon espacée le long de la partie tubulaire à mailles. Ces fils se tendent tandis que la partie tubulaire à mailles reste extensible au moment où la denrée alimentaire y est introduite, de sorte que ces fils élastiques de renforcement circonférentiels (12) exercent une pression dans la surface de la denrée alimentaire. Ceci permet d'obtenir un motif superficiel distinctif, la denrée alimentaire dépassant à l'intérieur de bandes (14) situées entre les délimitations circonférentielles.
