Abstract

Carcases of one species are injected with a stock or fat derived from another species. In particular, parts of mature egg-laying hens are rendered down into a stock and a fat extract which are subsequently injected intramuscularly into the exsanguinated and eviscerated carcass of a young turkey.

Description

SPECIFICATION Novel poultry product and process for making same This invention relates to a process for flavouring and improving the cooking and eating qualities of turkeys, especially young turkeys, and to a novel poultry product made by the process.
The turkey commonly sold in frozen carcass form to the domestic consumer is a mature bird weighing in excess of 3.5 kg. At such a weight a turkey carcass is not cheap and may be considered a luxury normally purchased only for special occasions.
Young broiler chicken-size turkeys are cheap to produce and can be sold to the consumer at about 3 per carcass, which is attractive as a "week-end joint" purchase, especially to the house-wife who would normally buy a broiler chicken for a week end. However, young turkey carcasses have characteristics unacceptable to the domestic consumer in that the carcasses when cooked have little flavour, the meat is very dry, and, because there is little or no fat in or between the muscles of a young turkey, the meat lacks succulence and is difficult to eat.
These unacceptable characteristics are not ameliorated by basting the bird during the cooking process because the basting fats and oils do not penetrate deeply enough into the muscular structure.
It is already known, for example in U.S. Patent 3366491, to provide a "self-basting" turkey product by injecting a large quantity of edible butter or fat into the bird post mortem, so that during the cooking process the injected fat or butter basts the bird.
However, the injection of these fats can produce a "non-poultry" flavour or taste which may not be acceptable to the consumer.
It is also known from U.S. patent 3695892 to provide a self-basting turkey that has been injected with a broth made from rendered-down turkey parts.
However, the prior art does not address itself specifically to the problem of ameliorating the disadvantages associated with a young turkey carcass, nor does the prior art suggest a novel poultry product.
According to a first aspect of the present invention there is provided a method of producing a poultry carcass having an authentic free-range chicken flavour and the succulence of a mature turkey, comprising the steps of, a) preparing a stock and/or a fat extract from the carcasses of mature egg-laying hens, and b) injecting the stock and/or the fat extract into the turkey carcass.
According to a second aspect of the present invention there is provided a poultry product comprising a turkey carcass, at least a proportion of the inter- and intra-muscular parts of which are impregnated with a stock and/or fat extract prepared from rendereddown carcasses of mature egg-laying hens.
Preferably the turkey is a young turkey and is prepared prior to injection by exsanguinating, plucking, eviscerating and curing the carcass.
According to a third aspect of the invention there is provided a method of producing an improved flavoured meat product comprising the steps of a) rendering down parts of an animal of a first species to form a stock and/or a fat extract, b) preparing an eviscerated carcass of an animal of a second species, and c) injecting the stock and/or fat extract into the carcass of the animal of the second species.
The invention will now be described by way of example with reference to the following example.
Preparation of Stock and Fat Extract Carcasses of mature hens which have been killed, plucked, eviscerated and thoroughly washed using conventional equipment were cooked in steam ovens for approximately 2 hours at 98-1000C. The extracted juices, fat and condensate were pumped through a centrifuge operating at approximately 16000 rpm where the stock, fat and fine solids were separated. At this stage the stock typically contained 1Ar%-2% by weight of soluble solids derived from the hen carcasses. The hot stock was then pumped through a heat exchanger and a vacuum concentrater and its volume reduced such that the final product contained 25-27% by weight soluble solids. The concentrated stock was further cooled and frozen for future use.
The fat extracted by the centrifugal process was likewise cooled and frozen for future use.
It was found that about 1 kg of concentrated stock and 1.25 kg of prepared fat extract were obtained from 100 kg of mature hen carcasses bythe process.
Preparation of young turkey carcasses Young turkeys of selected strains weighing between 1.8 kg and 2.7 kg were electrically stunned, exsanguinated, mechanically plucked, eviscerated and thoroughly washed and cooled.
The prepared cleansed carcasses were then cured in a brine of the composition detailed below for between 10 and 20 hours at a temperature below 5"C.
The cured carcasses were allowed to drain for about 30 minutes.
Atypical composition of the brine consists of, water 60% flaked ice 30% sodium chloride 5% sodium polyphosphate 2% sucrose 2% dextrose 1% Injection ofthe turkey carcasses A drained prepared eviscerated turkey carcass weighing about 1.8 kg was injected by a multiple injection machine in the breast, thigh and drumstick with between 85 and 140 gms of the prepared fat extract and with between 85 and 140 gms of the concentrated stock. The multiple injection technique ensured complete distribution of the stock and fat. A container of prepared edible offal was inserted into the cavity of the injected bird which was then placed in a bag, sealed and frozen using conventional methods.
In an alternative embodiment, the stock and fat extract were initially emulsified together into a cream. Between 170 and 280 gms of the cream were then injected into a drained prepared eviscerated turkey carcass weighing about 1.8 kg according to the above method.
Additional flavourings, spices and emulsifying salts may be added to either the stock and the fat extract or to the combined cream.
In an alternative method to preparing the fat extract, or as a means of obtaining additional supplies of suitable fats, the leaf fat from mature hens may be heated for approximately 40 minutes at 145-1 55"C and the resultant molten fat further clarified by means of a centrifuge or by filtration.
It is known that mature egg-laying hens (i.e. 2-3 years old) are not suitable for cooking and eating because their meat is too tough. However, if these fowls are rendered down to a stock and a fat it is found that the stock and fat have a very rich authentic farm-yard chicken flavour, which is nowadays rarely found in the typical factory farmed chicken.
By injecting this stock and fat into young turkey carcasses as described above, it is now possible to provide a novel poultry product which is about the same size as a young broiler chicken, has the meat and anatomical structure of a turkey, has self-basting properties, the flavour of a farm-yard chicken, and includes in substantial proportion much of the protein and fat values of a chicken.
By pasteurizing the stock and fat extract it may be rendered unnecessary to add preservatives to the stock and fat, and thus enhance its consumer acceptability.
It is seen that this invention illustrates the modification of the flavour, cooking and eating characteristics of the flesh of an animal of one species by injecting into a carcass of that animal an extract derived from a rendered down carcass of an animal of a second species. "Animal" in the context of this specification will be understood to include birds, quadrupeds and fish.
