Abstract

A method for packaging meat which comprises the steps of: a) cutting the meat into pieces; b) cooking the meat pieces in oil under conditions sufficient only to seal the meat but not destroy all bacteria within the meat; c) chilling the meat to 0-5 °C; d) placing the meat in a packaging container; e) adding sauce to the meat in the packaging container; and f) sealing the packaging container.

Description

METHOD FOT? 4CKAGT G MEAT
Field of the Invention
The present invention relates to methods for packaging meat and more particularly, but not exclusively, to methods of preparii g' and packaging meat as pre-prepared meals.
Most relevant prior art known to th applicant
The convenience food industry has greatly expanded its market share in recent years. A wide range of pre-cooked meals are now on offer in all but the smallest supermarkets throughout t__e United Kingdom. These meals may be consumed hot or cold. I_a the former case they are simply heated for a matter of minutes in a microwave. In many of these pre-cooked meals the meal is complete in that it comprises, for example, meat, sauce and vegetables. Some pre-cooked products, however, simply comprise cooked e. g fish or beef, in a sauce.
Essentially the consumer of a pre-cooked meal is saved the trouble of cooking the meal himself by the food manufacturer. A drawback of this arrangement is, however, that the food may mat be sterile when it is consumed if it is infected following c<α>_k___g: at the factory. This danger becomes particularly acute when a number of cooked or uncooked food items are combined i__ an ostensibly pre-cooked meal prior to packaging.
A further problem commonly associated with pre-cooked meat, is, that the meat has insufficient time to mature and is consequently tougher and less flavoursome than meat bought fresh and cooked at home. A technique used in domestic cooking of meat to enhance the flavour of the meat is to seal the meat in oil before stewing or roasting. In culinary terms sealing of meat is understood to mean cooking of the external surface of the meat alone to provide an impermeable barrier. This barrier is relied upon primarily to prevent loss of juices from the meat.
It is a general objective of the present invention to provide a method which combines the advantages of factory pre-cooked and home cooked meat-containing meals, enabling the meat to be packaged when covered in sauce and stored or transported to be fully cooked later.
Stimmfirv of the Invention
According to the present invention there is provided a method for packaging meat which comprises the steps of:
a) Cutting the meat into pieces;
b ) Cooking the meat pieces in oil under conditions sufficient only to seal the meat but not destroy all bacteria within the meat;
c) Chilling the meat to 0-δ ' C;
d) Placing the meat in a packaging container;
e) Adding sauce to the meat in the packaging container; and
f) Sealing the packaging container.
Advantageously the meat is injected with whey before step b i commences. Preferably in step b ) of the method the conditions selected to seal the meat are equivalent to in the region of 600 " Fahrenheit cooking temperature for a time of 3-5 minutes.
These conditions may be provided by frying, grilling or a variety of other known cooking methods. Preferably the meat is sealed by flame grilling.
Preferably in step b ) the meat is conveyed automatically through the cooking apparatus.
Preferably', before sealing the packaging container, a sauce and/or vegetables are added to the meat.
Prior to sealing the meat, the meat may be seasoned.
During sealing of the packaging container the atmosphere within the container is preferably flushed with one or more gases. Suitable gases include Nitrogen, Carbon Dioxide and Oxygen.
Description of the preferred Embodiments
In one preferred embodiment a meat such as beef is injected with whey, diced, seasoned in flour, herbs and spices, coated in oil and conveyed through a radiant heat grill oven such as to be exposed to a temperature of 600 ' Fahrenheit for a 5 minute period before being placed in a cold store for chilling to 0-5 ° C. The meat is then placed in a plastics punnet and
Figure imgf000005_0001
is poured over the meat. Pre-blanced carrots, onions and mushrooms are added to the meat and the punnet is sealed after flushing with carbon dioxide gas by stretching an impermeable film over the top of the punnet and gluing the film to the rim of the punnet. The packaged meat may then be stored and/or transported for several days without deterioration or proliferation of harmful bacteria. Cooking by the end-user is simply a matter of heating the meal in a conventional oven for approximately one hour a. a temperature of 200" Centigrade.
The manner in which the meat is cut, the nature of the seasoning, the nature of sauce and, optionally vegetables added to the meat, the nature of container and the precise manner in which it is sealed are, of course, merely examples which may easily be substituted with alternative methods and means by the skilled reader.
Addition of oil to the meat for cooking is optional. Many meat cuts may have sufficient intrinsic oil for the purpose.
The meat may be cut in the form of prime joints and/or offal, minced, diced or sliced, as appropriate. When seasoning, the meat may simply be dusted with flour and/or with herbs and spices.
The method of the present invention provides the opportunity for lactobacilli and other benign anaerobic bacteria to act upon the meat subsequent to packaging of the meat and prior to cooking by the consumer. These bacteria will tenderise the meat and provide it with a sweeter flavour. The risk of contamination of the meat by extrinsic bacteria which may be pathogenic is minimised by the sealing of the meat. The lactobacilli and other benign bacteria within the sealed meat will also limit the risk of colonisation of the meat by foreign bacteria in an analogous fashion to the host protecting role of the normal human gut microflora.
Thus, by merely sealing the meat and not fully cooking it prior to packaging and sale the quality of the meat is enhanced as is the resistance of the meat to infection. The meat, as bought, will be less likely to be contaminated with pathogens than equivalent fully pre-cooked meat. Furthermore, any pathogens present on the meat will be destroyed by the remaining cooking stages undertaken by the consumer. Although the method of the present invention is marginally less convenient to the consumer because of the need to -o-
complete the cooking process the time saving is still substantial and the greater hygiene and improved quality of the meat will more than compensate for this disadvantage.
Improvement of meat quality may be ensured or further enhanced by inoculation of the meat with lactobacilli or other suitable bacteria by, for example, injecting the meat with whey.
An important criterion of the present invention is that the cooking conditions used to seal the meat are not such as to exceed a core temperature within the meat of 65 ° C, at which most bacteria are killed.
Pre-treatment of any vegetables by blanching in a screw blanch or water-bath or by dipping in a 200 ppm chloring bath for 5 minutes is a desirable procedural step to avoid spoilage of the vegetables and to clean away pesticides.
