Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of preliminarily treating frozen block meat before it is used as a final cooking material.

[0002]

2. Description of the Related Art In a large-scale restaurant or a catering manufacturing company that manufactures a large amount of bento etc. at a time, when using meat material, frozen block meat (of one block is advantageous in terms of price or preservation) The weight is, for example, about 10 to 30 kg), but when using such frozen meat, if you cut it and cook it as it is, lye components and odors remain There is a problem that becomes worse.

The applicant of the present invention has already applied for a patent for a processing method for improving the above problems when using frozen block meat (Japanese Patent Laid-Open No. 63-102631). This known frozen block meat processing method, the frozen block meat is shredded into small pieces suitable for the application, and the small pieces are heated in hot water,
Immediately after heating, the small meat pieces are immersed in cold water to be cooled, and the cooled small meat pieces are drained and then frozen. And according to this known frozen block meat processing method, the removal rate of the lye component, fat content, etc. in the frozen meat is significantly improved.

[0004]

However, in the above-mentioned known method for treating frozen block meat, since the small pieces of shredded meat are heated in hot water, the lye component and the fat are discharged together. Water in the meat is released more than necessary, and there is a problem that the meat quality becomes dull and hard (the texture becomes bad), and when it is heated in boiling water, small pieces of meat are tiny. There has also been a problem that a large amount of meat pieces are separated, the occurrence rate of scrap meat is increased, and the yield is deteriorated.

In view of the above problems that occur when frozen block meat is used, the present invention has a good texture of meat even when it is heated in boiling water in the state of a small piece of meat. In addition to the above, it is an object of the present invention to propose a method for treating frozen block meat, which is capable of suppressing the occurrence rate of scrap meat during heating with hot water.

[0006]

The method for treating frozen block meat according to the present invention comprises a thawing step of thawing the frozen block meat to a temperature of -7 to 0 ° C, preferably -4 to -2 ° C, and the thawed block. A shredding step of shredding the meat into small pieces having a size and shape suitable for the application, and 20 to 40 parts by weight of a solution containing starch and salt is mixed with 100 parts by weight of the shredded small pieces. , A solution impregnation step of allowing the solution to blend into the small pieces for 10 minutes or more, and the solution-impregnated small pieces at a temperature of 85 to 100 ° C.
Of 60 minutes or more in hot water, a cooling step of soaking the small pieces immediately after heating in cold water to cool them, a draining step of draining the cooled small pieces of water, and a freezing of freezing the drained small pieces of meat It is characterized by performing a process.

The thawing step is carried out in order to shred frozen block meat with a disc cutter or band saw, and a large block (for example, one weight is about 10 to 30 Kg) of frozen block meat is stored in a thawing chamber at a temperature- Thaw to about 7-0 ° C. If the thawing temperature is lower than -7 ° C, the meat is too hard to be cut with a disc cutter or band saw,
On the other hand, if the temperature is higher than 0 ° C, the meat becomes too soft and difficult to cut and the shape retention of the cut meat is deteriorated, and preferably about -4 to -2 ° C.

In the shredding step, a large block of meat is shredded into small pieces of dice or slices according to the intended use.

In the solution impregnation step, a solution containing starch and salt is mixed with the shredded small meat pieces to impregnate the small meat pieces with the solution. Mix parts by weight and allow to mix for at least 10 minutes.

In the heating step, the solution-impregnated small meat pieces are heated to a temperature of 8
It is heat treated by immersing in hot water at 5 to 100 ° C. for 60 seconds or more. When the temperature of boiling water is lower than 85 ° C, the starch component and the salt component impregnated in the meat piece cannot be sufficiently heated, and also when the heating time is shorter than 60 seconds, the starch component and the salt component cannot be sufficiently heated.

In the cooling step, a small piece of meat in a high temperature state immediately after heating is immediately immersed in cold water (for example, a temperature of 5 ° C. or less) to cool it.

The draining step is to drain water from a cooled small piece of meat taken out from cold water, and is carried out by a conventional conventional draining method.

In the freezing process, drained small pieces of meat are packed and packed in packs, for example, about 1 kg each, and stored frozen.

[0014]

According to the frozen block meat processing method of the present invention,
The chopped small meat pieces are impregnated with a solution containing starch and salt, and the solution-impregnated small meat pieces are heated in hot water.First, the starch component in the solution impregnated into the small meat pieces is Is gelatinized by heating, and the salt component (sodium) acts on the protein of meat to cause the protein to become sticky, and these (gelatinization of starch and stickiness of protein)
Comes to coat the surface of the meat. Therefore, although the meat piece is sufficiently heated, the surface coating action makes it difficult for water (free water) in the meat to escape into the hot water, and the binding action of one meat piece becomes large. or,
Since the small pieces of meat that are still hot immediately after heating are immediately immersed in cold water, the fat that had been softened at the surface layer of the pieces of meat by heating is rapidly cooled and solidified. Is easily separated from the meat portion into water, and the separation of the lye component is also promoted.

[0015]

As described above, according to the method for treating frozen block meat of the present invention, even if the small pieces are shredded and heated in hot water, the small pieces are impregnated. As the starch component gelatinizes and the salt component causes the protein to stick, it coats the surface of the piece of meat, which makes it difficult for moisture (free water) and nutrients to escape from the meat, resulting in a juicy food. It has the effect of keeping the feeling. Further, when heated in boiling water, the starch component is gelatinized and the salt component causes the protein to become sticky, so it becomes difficult to separate minute meat pieces from the meat piece body portion, and the occurrence rate of scrap meat can be reduced. There is also an effect that it is possible (the yield is good).

[0016]

EXAMPLES Examples of the present invention will be described below.

In this embodiment, the frozen block meat is 1
One piece of frozen pork with a mass of about 20 kg is used, and this frozen block meat is thawed in a thaw until the temperature reaches -4 to -2 ° C.
It was cut into blocks of 50 mm square and further sliced to a thickness of 2 to 2.5 mm with a slicer.

On the other hand, vegetable oil 8.8%, salt 3.5%, potato starch 17.5%, and water 70.2% were thoroughly stirred to prepare a solution in which each component was sufficiently dissolved. 28.5 parts by weight of the solution was thoroughly mixed with 100 parts by weight of the above-mentioned small piece of meat (sliced meat), and left in a room at a temperature of 10 ° C. for 1 hour to allow the solution to sufficiently adapt to the small piece of meat.

Then, the solution-impregnated small piece of meat is heated to a temperature of 90.
After heating for 2 minutes in hot water at 0 ° C, the heated small pieces were taken out of the hot water and immediately immersed in cold water (temperature of 5 ° C or lower) for rapid cooling.

Then, the cooled small pieces of meat are drained and dried for 1K.
Each g was placed in a plastic bag, vacuum-packed, and then frozen and stored in a freezer.

Comparative Example A small piece of meat processed according to the treatment method of the embodiment of the present invention as described above and a conventional method, that is, a frozen block meat made into a small piece of meat (sliced meat) as in the embodiment of the present invention, are hot water as they are. When heated in a medium, the heated small meat pieces were immediately quenched in cold water, drained and compared with frozen small meat pieces, Table 1
The examination result is as follows.

[0022]

[Table 1]

In Table 1, "yield after heating" is
It is the ratio of the weight of meat after heating to the weight of meat before heating.

As can be seen from the examination results in Table 1, the method of treating frozen block meat to which the present invention is applied has a wet appearance in comparison with the conventional method, and the residual water content in the meat pieces is higher. The result was that after cooking, there was a juicy texture after cooking (the dryness peculiar to cooked meat disappeared) and it was soft even when cold. Further, the yield when the hot water was heated was far better when the present invention was applied than when the conventional method was used.
