(54)-thle: STABILIZING AID FOR UNSTABLE OBJECTS, IN PARTICULAR FOODSTUFFS (54) Bezeichnung: STAB1LITATSHILFE BEI El NEM LABILEN OBJEKT, INSBESONDERE LEBENSM1TTEL (57) Abstract A stabilizing aid which preserves the cohesion and shape of loose objects, in particular foodstuffs such as meat and sausages, during and after manufacture, consists of a supporting constituent which on heating dissolves slowly or quickly, dep(.,ding on its composition. The supporting constituent is advantageously dimensionally stable and consists of glue-, gelatine-. or glucoselike or starch-containing material. Preferably, this stabilizing aid is a starch-based, heat-processable.. granular polymer.

(57) Zusamnienfassung Umn bei lockeren Objekten, speziell Lebensmittel, wie Fleisch- und Wurstwaren, bei und nach der Fertigung den Zusammenhalt und die Fortngebung zu sichern, dient die Stabilitfitshilfe, welche aus einem st~tzenden Bestandteil besteht, der sich bei Erwiirrung je nach Zusammensetzung langsam oder rasch auffist. Der stiltzende Bestanditeil ist zweckmiissig formf'est und besteht aus leim-, gelatine- oder glucoseartigemn oder stdrkehaltigem Material. Vorzugsweise k6nnen diese Stabilitatshiflfen au seinem polyrneren thermoplastisch verarbeitbaren Granulat auf Starkebasis geformt sein.

Stabilizing Aid for Unstable Objects, in Particular Foodstuffs In the manufacture of loose and stable objects it is customary to tie them in order to maintain their structure and shape. The insertion of pins made of wood or plastic and the clipping of sausages is also customary. The labor involved in this is relatively extensive and the subsequent removal awkward.

In certain cases there is the danger of damage as well as the possibility of soiling.

In connection with sausage skins in particular the use of substitutes for the natural casings has been known for a long time. For example, French FR-A-1 260 250 suggests to provide sausage casings made of plastic insoluble in water with a hydrophilic additive for improving the permeability to water vapor. Pecto-cellulose or starch are used as such additives, for example.

German DE-B-10 66 901, on the other hand, deals with the 0. application of a layer of fat or bacon around a sausage mixture; In a variation of the embodiment it is suggested to spread the layer of fat or bacon on a foil made of an edible material and to apply all this together around the sausage mixture.

These embodiments require great durability of the edible materials selected and its use is contemplated mainly for the industrial sector of food production.

U

.77 2 But no usable stabilizing aids which dissolve in water or at a predetermined temperature and are made of an edible material are known for household or farm use. Up to now, and in particular in connection with the production of rolled meat for rolled roasts or"rolled hams, or with cordon bleu and similar products, stabilizing aids of artificial or natural materials which were neither edible nor dissolving, had to suffice. For example, rolled hams were wrapped in elastic plastic nets and cordon bleu was held together with wooden toothpicks.

S: Quite recently it has become known to produce polymeric, thermoplastically usable starch granulates. Such a material is excellently suited for the manufacture of stabilizing aids. Up to now their use was primarily intended in agriculture, for example in the manufacture of dissolving cover foils for cold frames. By way of example, please refer ta W090/01043 and W090/05461.

The present invention provides a stabilizing aid which becomes effective in connection with an S; unstable object, in particular foodstuffs, during the cooking or roasting process, in order to assure coherence and to avoid manual removal operations.

The stabilizing aid is formed of a stable, deformable or elastic component of thermoplastically workable material and has the shape of a high-tensile or elastic tying agnet, such as a cord, net or wire, which is applied to the unstable object to be stabilized. The component may 0 consist of single or multiple parts. Advantageously, it is made of a glue-like or starch-containing material, such as gelatin, glucose or biologically degradable, edible polymers, preferably a polymeric, thermoplastically workable granulate which dissolves, depending on its composition, slowly or quickly when heated and is integrated into the unstable object. The gelatin, glucose, starch-containing material or biologically degradable polymers may be of the regular kind or may be hardened and may contain suitable additives. The stabilizing aid component which is applied to or inserted into the unstable object or clamped to it 0 o• I. may also be designed in the form of a pin or needle.

If the stabilization aid is a hose-like shape formed out of a heat-dissolvable, edible cord, it is advantageous to fill it with a material which affects the dissolution process during heating. In connection with elongated objects, such as sausages, the ends of certain types are closed by metal clips which are o relatively sturdy and which cannot be removed without effort and Swithout the danger of damage. These clips, which supply the Scohesion and maintenance of shape of unstable objects such as sausages, are advantageously made of a material which automatically dissolves with heating.

The stabilization aid can be used for loose, unstable, elongated objects of all types. It is usable for the preparation and cooking or roasting of foodstuffs, especially in those cases, where cohesion and maintenance of shape during and after -3-
