IMPROVED RECONSTITUTED MEAT PRODUCT

Abstract: A reconstituted meat product comprising a plurality of meat pieces agglomerated together, characterized in that the meat pieces are of an elongate shape and that they are arranged in a substantially helical array through the meat product. The helical arrangement of the meat pieces aids in binding the meat pieces and gives to the reconstituted product a natural appearance.

Description: "IMPROVED RECONSTITUTED MEAT PRODUCT" FIELD OF THE INVENTION The present invention relates to an improved reconstituted meat product and more particularly to a reconstituted meat product which may be severed to produce steak-like pieces. BACKGROUND ART Many efforts have been made in the past to agglomerate together small meat pieces to produce a reconstituted meat product having the qualities of a piece of primal meat. Primal meat generally has longitudinally extending muscle fibres. In the formation of steak-like products it is normal to cut across these longitudinally extending muscle fibres. In the formation of reconstituted meat products it has been proposed previously to orientate the fibres of the meat particles in a given direction and then to cut across the direction of those fibres in an effort to produce a product approximating that of natural primal meat (see for example Australian patent specification 19235/70 and 29961/71). These efforts have been unsuccessful in that the meat products so formed fail to show the coherence exhibited by natural meat products though they do have desirable fibrous properties. In order to cause these products to cohere adequately it has previously been proposed either to add binders of various types to the reconstituted product such as salt, or to encase the reconstituted product in a natural or synthetic skin to hold the product together (see for example U.S. Patent Specification 3852487). These binders have improved the cohesion of the comminuted meat pieces together however they often impart their own adverse properties to the finished product or detract from its appearance. Thus salt is now considered to adversely affect health and is preferably avoided in large amounts. Similarly, large quantities of finely ground meat emulsion binder included in reformed meat products can give the product an unnatural colour and/or texture. Thus at the date of this invention it was known to produce textured products without good adhesion and to produce reasonably well cohered products without texture. It was not, however, possible to produce a product having both desirable qualities simultaneously. DISCLOSURE OF THE INVENTION The present inventor has realized that by forming a reconstituted product of meat particles which are elongated in form and by arranging those meat particles in a substantially helical array through the meat product one may achieve a product having good physical coherence and a natural textured appearance even though the structure of the reconstituted product is from a theoretical point of view quite different from that of natural meat. The present invention accordingly consists in a meat product comprising a plurality of meat pieces agglomerated together, characterized in that the meat pieces are arranged in a substantially helical array through the meat produc . It should be pointed out at this juncture that each piece of meat will be made up of a number of meat fibres and the fibres of the meat pieces do not themselves need to be arrayed in any particular way but rather the meat pieces should be elongated or stretched out such that in the meat product they are arranged in a substantially helical array. The meat product is preferably formed in a cylindrical shape having a longitudinal axis. The meat pieces are preferably arranged in a substantially helical array around that longitudinal axis. If the meat product is to be formed into steak-like pieces these steak-like pieces are preferably cut from the cylindrical meat product at right angles to the longitudinal axis of the meat product such that the meat pieces in the steak-like article will themselves traverse that article in a substantially helical fashion. The helical array of the meat pieces is believed to substantially improve the coherence of the reconstituted meat product as compared with any previously known reconstituted meat product. It will be recognized that the products according to this invention do not need to be cylindrical or circular in shape. Other shaped products may be readily produced and are encompassed within this invention provided the meat pieces are arranged in a generally helical array. In preferred embodiments of the invention from 40 to 70% of the number of meat pieces in the meat product are so arranged in the meat product that they have a minimum angle of from 10 to 50° relative to the axis of the helical array when seen at right-angles to that axis and with the meat pieces appearing to traverse that axis. Preferably the meat pieces have a length of from 10 millimetres to 100 millimetres and a transverse dimension of from 2 millimetres to 70 millimetres. The elongated meat particles may be used on their own to form the meat product or they may be mixed together with finely comminuted meat material which is not itself elongated. The finely comminuted meat material may comprise meat which contains sinews such that the sinews are rendered substantially organoleptically undetectable by the comminution of the original meat material. In a particularly preferred embodiment of the present invention the surface of the individual meat pieces are rubbed or otherwise roughened prior to being agglomerated together to increase their natural coherence. The formation of a rubbed or otherwise roughened surface on the meat pieces is preferably achieved by passage of the meat pieces through the counter-rotating knives described in the aforementioned PCT patent specification PCT/AU86/00163. The roughening could however be produced by merely mixing the meat pieces together for a prolonged period. The latter course of action however is disadvantageous in that it tends to give the meat an unduly dry texture. The meat products according to this invention are preferably produced in the apparatus described in PCT patent application PCT/AU86/00163 however other mechanisms could be used to achieve a similar result. The contents of PCT patent specification PCT/AU86/00163 as incorporated herein by reference. Other machines and methods may, however, be used to produce the product according to this invention. The meat pieces may be fed manually into a suitable container while combining the meat pieces into the desired array. In another alternative the extrusion machine according to Australian Patent Specifications 451786 or 452429 may be adapted provided that the product produced thereby is fed into a container which is caused to rotate about its longitudinal axis to induce the meat particles to achieve a helical array rather than an array parallel to the direction of extrusion. It is of the essence of the present invention that the meat be raw at the time of the formation of the meat product and it is desirable that once formed the meat product is frozen. Preferably, the meat is directed cooked from the frozen state although it may thawed and cooked from a thawed state. The meat may be the muscle derived from any suitable mammalian or avian species of animal. THE BEST MODE OF CARRYING OUT THE INVENTION Example 1 A beef carcass was boned and the substantially sinewless meat on the carcass, which comprised about 85% by weight of the meat, was passed through a mincer having a plate carrying 12mm diameter holes. The sinewed meat comprising the remainder of the meat from the carcass was passed through a mincer having a plate carrying 8mm diameter holes. The two minced meats were mixed together and again passed through the mincer carrying the plate having 12mm holes. The combined minced meat product was then passed through a machine as described in PCT Patent Specification PCT/AU86/00163. The product therefrom was fed into a cylinder of 100mm diameter. After the container was filled it was frozen. The product so obtained as subject to examination and found to have a good natural meat appearance with the meat particles therein firmly cohered together when the product had thawed and when cooked directly from the frozen state. The majority of the meat pieces were found to be arranged in the product in a helical array about the longitudinal axis of the product. The individual meat pieces were found to be elongated and of a rough or stringy nature due to their passage between the rotating blades of the machine described in Example 2 The process of Example 1 was repeated but incorporating in the meat prior to putting it into the machine as described in PCT Patent Specification PCT/AU86/00163 a number of pieces of black string of about 200mm length. After being frozen and thawed the product was examined. It was found that the majority of the pieces of string were helically arranged in the product about its longitudinal axis.
