Abstract

Frozen blocks (1) of poultry meat are tempered for a minimum period of 48 hours to bring the temperature of the blocks up to -10 degress celcius to -12 degrees celcius. After tempering, the tempered block is flaked and the flakes are mixed with the poultry skin flakes, water, phosphate, salt and protein. The mixture is minced. The minced mixture is held at a temperature of from 0 to -3 degress celcius for a period of from 2 to 3 hours. After forming, the formed pieces are settled for a period of from 10 to 20 seconds by leading them along an elongated conveyor (30). After dusting, the formed pieces are battered and further settled for a period of not less than 20 seconds prior to flash frying.

Description

“A method for preparing a poultry product” Introduction The invention relates to a method for preparing a poultry meat, especially chicken, food product.

In my UK-A-2269083 I have described a method for preparing a chicken food product in which excess crumb is removed from the formed meat pieces prior to delivery into a fryer. This has the considerable advantage of optimising fryer usage and in providing a consistent product.

This invention is directed towards the further optimisation of the production of such poultry pieces and improving the physical and organoleptic properties of poultry products produced.

Statements of Invention According to the invention there is provided a method for preparing a poultry meat product comprising the steps of:tempering frozen blocks of poultry pieces; flaking the block of tempered poultry pieces into meat flakes; mixing the meat flakes with water, protein, and binding agents; mincing the mixture thus formed; holding the minced mixture at a temperature of from -2°C to -5°C for a period of at least two hours; S80475 forming the minced mixture into pieces of desired shape; settling the formed pieces for a period of at least 10 seconds; applying a predust to the settled formed pieces; applying a batter to the predusted formed pieces; at least partially cooking the predusted battered pieces; and freezing the cooked pieces.

In a particularly preferred embodiment of the invention the minced mixture is held for a period of from 2 to 3 hours. Preferably the minced mixture is held at a temperature of from 0°C to -3°C.

In a preferred arrangement the formed pieces are settled for a period of from 15 to 20 seconds prior to application of a predust. Preferably the formed pieces are settled by leading the formed pieces along a conveyor to a pre-dusting station.

In one embodiment of the invention the method includes the step, after application of batter, of settling the battered pieces for a period of at least 10 seconds prior to cooking. Preferably, the battered pieces are settled for a period of at least 20 seconds prior to cooking.

In a preferred arrangement the battered pieces are settled by leading the battered pieces along a conveyor to a bath of hot cooking oil.

The invention also provides white meat food products whenever prepared by the method of the invention.

Detailed Description Referring to the drawings and initially to Fig. 1, there is illustrated a method for preparing a poultry food product according to the invention.

Frozen blocks 1 of poultry meat, typically white chicken meat, are arranged on shelves 2 of a tempering rack 3 as illustrated in Fig. 2 to allow for air circulation. The blocks 1 are tempered in step 4 on the racks for a minimum period of 48 hours to bring the temperature of the blocks up from -20°C to between -10° and 12°C. The racks used and the processing conditions for tempering ensure that an even tempering of the poultry meat is achieved in a highly efficient manner.

After tempering, a tempered block is flaked in step 9. The block is delivered by a pusher ram to knives 5 on a rotating flaking drum 6 which is illustrated in Figs. 3 and 4. The flaking drum and knife arrangement is similar to that described in my UK-A-2269083. The flaking machine 7 includes access doors 10, 11 to facilitate cleaning. The flaked pieces are delivered through a discharge chute 12 into a tote holding bin 13.

Poultry skin is flaked in a similar manner and the flaked meat and skin is delivered from the tote bins 13 into a hopper feed of a paddle mixer, where they are mixed along with water, phosphate, salt and protein in a mixing/hlending step 20. The mixing is carried out for a period of between 1 and 5 minutes, preferably between 2 and 4 minutes, and usually for about 3 minutes prior to mincing.

After mixing, the mixture is minced through a 3mm head in a mincing step 21 and the minced mixture is collected in a tote bin. The minced mixture is then transferred to a cold room in which the mixture is held at a temperature of from 2°C to -5°C for a period of at least 2 hours and preferably at a temperature of from 0°C to -3°C for a period of between 2 and 3 hours. I have found that this holding step 22 is particularly important in optimising the subsequent process steps. By virtue of the holding step easier forming of the mixture with less energy input is facilitated.

After holding 22 the minced mixture is delivered to a shaping/forming unit 25, in which the mixture is formed into pieces of desired shape in a forming step 23. The pieces may, for example, be formed into shapes such as nuggets, burgers and the like. After forming, the formed pieces are settled in a settling step 24 for a period of at least 10 seconds, preferably for a period of from 15 to 20 seconds. In this case the formed pieces are settled most efficiently by leading them along an elongated conveyor 30.

A predust is applied to the settled formed pieces in a pre-dusting step 25, using a predusting unit 31. After predusting, batter is applied in one or more stages in a battering step 26 using a batter applicator 32. Various other steps such as additional battering, crumb coating etc may also be used, however they are not described in detail as they are not an essential part of this invention. Subsequent to the battering step 26, the battered product are further settled in a settling step 27 for a period of at least 10 seconds and preferably approximately 20 seconds prior to cooking. The settling is most efficiently achieved by leading the battered formed pieces along a settling conveyor 36 prior to delivery into a fryer 37 in which the meat pieces are flash fried in a cooking step 28 at a temperature of at least 185°C for a period of not less than 20 seconds. This is a partial cook. After frying, the poultry meat pieces are frozen, for example, in a spiral freezer 38 in a freezing step 29 prior to packaging in step 30.

In the arrangement illustrated in Fig. 7 the battered poultry pieces are delivered directly from the conveyor 36 to an in-feed conveyor 37 which is partially immersed in and delivers the battered pieces into cooking oil, which is shown at a level L in the drawing.

In an alternative arrangement illustrated in Figs. 8 and 9, the settling conveyor 36 includes a discharge section 40 which is pivotally mounted at 41 for angular adjustment with respect to the main body of the conveyor 36. In use, the discharge portion 40 of the conveyor is adjusted so that the discharge end of the conveyor section 40 is not immersed in, but lies just above, the level L of the cooking oil in the fryer 37. In this way, the cooking of the product is even more closely controlled as there is no precooking by the product encountering a hot section of conveyor prior to immersion in the cooking oil. This is particularly important for products with a light batter which can be easily damaged, destroying their physical and organoleptic properties.

I have found that the new method described above offers considerable advantages over the prior art and in particular assists in further optimising the process for preparing poultry meat pieces.

Many variations on the specific embodiments of the invention will be readily apparent and accordingly the invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail.
