Cooked and frozen meat meal

Abstract: A process for preparing a frozen meal which comprises cooking pieces of meat, cooling, adding a thickening agent, mixing, forming into a block, freezing and finally packing with one or more vegetables.

Description: The present invention relates to a frozen meal, more particularly to a process for preparing a frozen meal containing meat pieces and one or more vegetables. In the preparation of frozen meals for the food service industry such as aircraft meals containing meat with, for instance, potatoes and vegetables, pieces of meat are mixed with a cooked sauce, pressed in a standard former into a block, and then frozen and packed with the potatoes and vegetables in alu-trays. The product is normally heated in a convection oven for serving in a tray. The addition of thickeners to meat is described in US-A 3681094 and in Patent Abstracts of Japan - vol. 11, no. 69 (C-407)(2516) 3 March 1987 : vol. 15, no. 211(C-836)(4739) 29 May 1991 and vol.13, no. 362 (C-625)(3719) 14 August 1989. We have found that if the meat pieces are mixed with a sauce and a thickener before pressing in the former, the cooked dish for serving has an attractive appearance whereby the meat pieces in the fluid sauce spread out in the tray. Accordingly, the present invention provides a process for preparing a frozen meal which comprises cooking pieces of meat, cooling to at least a chilled temperature, adding a thickening agent in gelled form, mixing, forming into a block, freezing and finally packing with one or more frozen vegetables. The pieces of meat are conveniently dice, chunks, slices, cubes or segments, for instance, of a size normally used in stews or ragout. The pieces of meat may be obtained by dicing meat preferably tempered to a freezing temperature e.g. -1°C to -3°C. Any kind of meat is suitable in the process, for example, beef, pork, calf, lamb, veal, reindeer or chicken. Before cooking, the meat pieces are advantageously marinated, for instance, with starch, salt or spices. The marination may be carried out by conventional processes such as vacuum tumbling, soaking or injection. After marination the marinated meat pieces may be browned for instance at about 180° to 220°C for a period of from 1 to 3 minutes advantageously in a square belt oven where the meat pieces are conveyed between two teflon belts through the cooking section. The meat pieces are then cooked by any conventional method, for example, by adding about 20% water and cooking for from 1 to 2 1/2 hours, more usually from 1 1/2 to 2 hours in the bouillon in a steam cabinet. After cooking, the meat pieces in the bouillon are cooled conveniently to a temperature from 35° to 45°C, preferably 38° to 42°C. The thickening agent may be a gelling agent that breaks down during freezing and reheating for consumption such as a gum or a starch e.g. gum arabic or gelatin. Before adding the thickening agent, the meat pieces are preferably separated from the bouillon and the meat pieces may be either chilled or frozen. The bouillon is then used in a sauce e.g. a creamy sauce, to which the thickening agent is added. The amount of bouillon used in the sauce may conveniently be from 10 to 30% by weight. The thickening agent is preferably dissolved or suspended in water at a concentration of from 20 to 30 % by weight and added to the sauce at a temperature from 60° to 80°C. The amount of thickening agent is advantageously from 2 to 4% by weight based on the weight of the sauce. The sauce is conveniently prepared and heated to a temperature from 90°C to 95°C and cooked for a period of about 4 to 6 minutes and then cooled, preferably to a temperature from 8°C to 15°C. The cooling of the sauce may be carried out for instance in a scraped surface heat exchanger or in a kettle. After cooling, the sauce containing the thickener is allowed to stand to allow the gel to set e.g. from 15 to 18 hours at a temperature from 6° to 15°C. The mixing of the chilled or frozen meat with the cooled sauce containing the thickening agent may be carried out in a meat mixer with gentle mixing for a short time e.g. from 1 to 3 minutes. When the sauce is cooled in a scraped surface heat exchanger, the gel strength is reduced and it is preferably mixed with frozen meat whereas when the sauce is cooled in a kettle the gel strength is not reduced and it may be mixed with chilled meat e.g. at a temperature from 1°C to 4°C. The use of chilled meat rather than frozen meat is less costly and less water is lost during the chilling process compared with freezing. After mixing, the meat pieces may be formed in a former to blocks of a standard size before freezing and packing with vegetables such as frozen cooked potatoes, cabbage, carrots, peas, beans, sprouts, brocolli etc. The following Example further illustrates the present invention. Example Beef was tempered to -2°C and diced to pieces having dimensions of 15 x 20 x 28 mm. The diced pieces were then marinated in starch, salt and spices by vacuum tumbling for 10 minutes at 5°C and then browned in a square belt oven for 2 minutes at 200°C. The browned diced meat was then cooked in a bouillon in a steam cabinet. After cooking the meat was cooled to 40°C and the bouillon separated from the meat. The diced meat pieces were chilled to + 2°C while the bouillon was used in an amount of 20% as an ingredient in a sauce to which 3% by weight of gelatin was added at 75°C. The gelatin was added solubilised in warm water at 60°C at a concentration of 25 g/100 g water. After cooking the sauce was cooled and then allowed to stand for 16 hours at 8°C to allow the gel to set. The chilled or frozen meat and garnish were then mixed with the sauce for 1.5 minutes and then formed in a standard forming equipment and frozen into blocks having dimensions of 60 x 70 x 35 mm. The blocks were then packed with e.g. frozen, cooked potatoes and vegetables into trays. When reheated for consumption in a convection oven, the dish has an attractive appearance whereby the meat pieces in a fluid sauce spread out in the tray.
