Hereinafter, each configuration of the aging device 1000 will be described.

Aging Housing (100)

Referring to FIG. 2, the maturation housing 100 may include a maturation space 200, which will be described later.

More specifically, the maturation housing 100 may be provided to surround at least the maturation space 200, as shown in FIG. 2.

Meanwhile, the maturation housing 100 includes a cooling unit 300 that cools the maturation space 200, a humidifier 400 that humidifies the maturation space 200, and a device for measuring the state of the maturation space 200. A sensor unit 500 that controls the sensor unit 500 and a control unit 600 that controls at least one of the cooling unit 300 and the humidifying unit 400 may be provided.

Meanwhile, although not shown in the drawings, a housing door (not shown) that opens and closes the maturation space 200 may be further provided on one side of the maturation housing 100.

Accordingly, when the housing door (not shown) is opened, the meat (mt, see FIG. 4), the first aged meat (10, see FIG. 10 (b)), and the At least one of the second aged meats (20, see FIG. 10 (c)) may be introduced or withdrawn. Meanwhile, when the housing door (not shown) is closed, at least one of the meat (mt, see FIG. 4) and the first aged meat (10, see FIG. 10 (b)) introduced into the aging space 200 One can be ripened.

Ripening space (200)

Referring to FIG. 5, meat to be aged (MT, see FIG. 4) may be placed in the aging space 200.

Meanwhile, before the aging, the meat (mt, see FIG. 4) may have a first color (cl1, see FIG. 11 (a)).

Here, the first color (cl1, see FIG. 11 (a)) may mean a red color. Here, the red color system can be understood as a concept that includes bright red.

Meanwhile, the meat color of meat (mt, see FIG. 4), that is, beef, can be expressed by myoglobin, a pigment protein in the muscles of meat (mt, see FIG. 4).

More specifically, referring to FIGS. 6 (a) and 10 (a), myoglobin may include at least one of iron (Fe), oxygen (O2), and protein (globin).

Myoglobin, depending on whether it is combined with oxygen (O2), is divided into deoxymyoglobin (dm), oxymyoglobin (om), and metmyoglobin, as shown in Figure 6 (a) and Figure 10 (a). It can exist in at least one of three states: (metmyoglobin, mm).

Here, oxymyoglobin (om) may refer to the basic state of myoglobin, which plays a role in storing oxygen (O2). Referring to FIG. 6 (a) and FIG. 10 (a), oxymyoglobin (om) may have a red color in a state in which divalent iron (Fe+2) and oxygen (O2) are combined.

Accordingly, the meat color of the meat containing oxymyoglobin (om) may be red, and as described above, before the aging, the meat (mt, see FIG. 4) has the first color (cl1, (See Figure 11 (a)) In other words, it may have a red color system. Here, the red color system can be understood as a concept that includes bright red, as previously explained.

Meanwhile, referring to FIG. 10 (a), deoxymyoglobin (dm) may refer to the state in which the above-described oxymyoglobin (om) has lost oxygen (O2). When meat is not in contact with oxygen (O2), mainly due to vacuum packaging, oxymyoglobin (om) loses oxygen (O2) and is converted to deoxymyoglobin (dm), which can take on a dark red color.

Accordingly, the meat color of cooking oil containing deoxymyoglobin (dm) may be dark red. Here, the dark red color system can be understood as a concept that includes the red color system described above, that is, a red color that is more black than bright red.

However, this deoxymyoglobin (dm) is exposed to an environment where it can come into contact with oxygen (O2), for example, when meat is exposed to the air for a certain period of time, for example, about 30 minutes, as shown in Figure 6 (a). Likewise, deoxymyoglobin (dm) can be converted back to oxymyoglobin (om) by combining with oxygen (O2).

Therefore, the dark red color of meat can be reduced to the red color, that is, bright red, by deoxymyoglobin (dm).

Meanwhile, for metmyoglobin (mm), referring to Figure 6 (a), oxymyoglobin (om) is exposed to oxygen (O2), and the divalent iron (Fe+2) contained in myoglobin is converted to trivalent iron (Fe+ 3) It may mean an oxidized state. Mainly, when meat is exposed to oxygen (O2) for a long time, oxymyoglobin (om) is oxidized (+O2) and converted to metmyoglobin (mm), which can cause browning.

Accordingly, the meat color of meat containing metmyoglobin (mm) may be brown.

As described above, deoxymyoglobin (dm) is easy to convert to oxymyoglobin (om), while metmyoglobin (mm) may be difficult to convert to oxymyoglobin (om).

Meanwhile, as described above with reference to FIG. 6 (a), the phenomenon of browning the color of meat as oxymyoglobin (om) is oxidized (+O2) and converted to metmyoglobin (mm) is caused by the conventional dry-aging method. It was a problem.

Here, the dry-aging method can be understood as a concept that includes a method in which meat is aged at a set temperature and set humidity in an air circulation atmosphere.

As described above, aged meat aged in this conventional dry-aging method is aged by exposing the meat to an environment where air circulates, so the moisture (ms, see Figure 6 (b)) contained in the meat during the aging process. ), the flavor of the aged meat may be concentrated as at least a portion of it is dehydrated from the surface of the aged meat to the outside. Accordingly, aged meat aged through dry-aging is characterized by a rich flavor.

On the other hand, as described above, in aged meat aged by a conventional dry-aging method, at least a portion of the moisture (ms, see Figure 6 (b)) contained in the meat is dehydrated from the surface of the aged meat to the outside during the aging process. Therefore, there was a problem that the surface of the aged meat was dried.

In addition, aged meat produced by the conventional dry-aging method reacts with oxygen from the surface of the meat being aged and undergoes oxidation (ox, see Figure 6 (b)), so the meat color on the surface of the aged meat is as described above. As shown, there was a browning phenomenon.

Therefore, the aged meat produced by the conventional dry-aging method is browned as described above, and the surface of the dry aged meat (ox, see FIG. 6 (b)), for example, about 40% or more, is cut off. There was a problem of decreased yield.

In other words, as described above, the browned and dry surface (ox, see FIG. 6 (b)) of aged meat is discarded because consumers do not prefer it.

In addition, as described above, about 40% or more of the aged meat produced by the conventional dry-aging method was cut and discarded, so due to the loss rate of about 40% or more described above, the meat produced by the dry-aging method There was also the problem of the price of aged meat becoming expensive.

Accordingly, in the present invention, the flavor of the aged meat, which is an advantage of dry-aging as described above, is maximized, and the browning and dehydration phenomenon on the surface of the aged meat is minimized, thereby minimizing the loss rate and maximizing the yield of aged meat. A manufacturing method is provided.

Meanwhile, referring to FIG. 9, in the maturation space 200, the first aged meat (10, see FIG. 8), in which the meat (mt, see FIG. 4) is first aged by dry-aging, is placed. It may be possible.

Meanwhile, the surface (ox) of the first aged meat (10, see FIG. 6 (b)) may have a second color (cl2, see FIG. 11 (a)).

Here, the second color (cl2) may mean a brown color.

As described above, the meat (mt, see FIG. 4) has the first color (cl1, see FIG. 11 (a)), that is, a red color, before the first ripening, while the meat (mt, see FIG. 4) has a red color lineage before the first ripening. As shown in Figure 6 (a) during primary aging, oxymyoglobin (om) on the surface (ox) of the meat (mt, see Figure 4) is oxidized (+O2) and converted to metmyoglobin (mm). It may be because

Therefore, the surface (ox) meat color of the first aged meat (10, see FIG. 6 (b)) produced by the first aging of the meat (mt, see FIG. 4) is the second color (cl2, (See Figure 11 (a)) In other words, it can be browned.

Therefore, in the present invention, the second color (cl2, see FIG. 11 (a)) of the surface (ox) of the first aged meat (10, see FIG. 6 (b)), that is, the brown color, is changed to the first color (cl1). , see FIG. 11 (a)), that is, it provides a method of reducing it to the red color system.

On the other hand, the meat (mt, see FIG. 4), as shown in FIG. 6 (b), during the first aging, at least a portion of the moisture (ms) contained in the meat (mt, see FIG. 4) Dehydration may occur externally from the surface of the cured meat.

Accordingly, the surface of the first aged meat (10, see FIG. 6 (b)) may dry out.

Therefore, in the present invention, referring to Figure 10 (b), the moisture (ms) inside the first aged meat 10 is ejected toward the surface of the first aged meat 10, and the first aged meat ( 10) Provides a method to provide moisture (ms) to the surface.

Cooling unit (300)

Referring to FIG. 2, the cooling unit 300 may cool the maturing space 200.

To this end, the cooling unit 300 may be provided in the maturation housing 100 surrounding the maturation space 200.

More specifically, the cooling unit 300 is provided inside the maturation housing 100, and includes a cooling pipe (not shown) that provides cold air (cooling gas) to the maturation space 200, and the cooling pipe (not shown). It may include at least one of a cooling gas supply device (not shown) that supplies cold air.

Accordingly, the cooling unit 300 can cool the maturation space 200 by supplying cold air to the inside of the maturation space 200.

Therefore, when the meat (mt, see FIG. 4) or the first aged meat (10, see FIG. 6(b)) is placed in the ripening space 200, the meat (mt, see FIG. 4) (see) and the first aged meat (10, see Figure 6 (b)) may be aged at a low temperature in a predetermined temperature range.

Meanwhile, the cooling unit 300 may be controlled for first maturation by a dry-aging method by the control unit 600, which will be described later, so that the maturation space 200 is in a predetermined first temperature range. Here, the first temperature range may be 1°C or more and 5°C or less.

Accordingly, the meat (mt, see FIG. 4) disposed in the aging space 200 can be first aged to produce first aged meat (10, see FIG. 6 (b)).

In addition, the cooling unit 300 controls the second maturation by a wet-aging method so that the maturation space 200 is in a predetermined second temperature range by the control unit 600, which will be described later. It can be. Here, the second temperature range may be 1°C or more and 5°C or less.

Accordingly, the first aged meat (10, see Figure 10 (b)) disposed in the aging space 200 is subjected to secondary aging to produce second aged meat (20, see Figure 10 (c)). It can be.

Humidification unit (400)

Referring to FIG. 2, the humidifier 400 may humidify the maturation space 200.

To this end, the humidifying unit 400 may be provided below the maturing space 200.

More specifically, as shown in FIG. 2, the humidifier 400 is provided on the lower side of the maturation space 200 inside the maturation housing 100 and transmits moisture (hm) into the maturation space 200. It may include a humidifying tank (not shown) containing water to provide. Here, the water may be, for example, purified water.

Accordingly, the humidifier 400 can humidify the maturation space 200 by providing moisture (hm) from the water to the inside of the maturation space 200.

Therefore, when the meat (mt, see FIG. 4) or the first aged meat (10, see FIG. 6(b)) is placed in the ripening space 200, the meat (mt, see FIG. 4) (see) and the surface of the first aged meat (10, see FIG. 6 (b)) may be humidified.

Meanwhile, the humidifier 400 may be controlled for first maturation by a dry-aging method by the control unit 600, which will be described later, so that the maturation space 200 is in a predetermined first humidity range. Here, the first humidity range may be 70% or more and 80% or less.

Accordingly, the meat (mt, see FIG. 4) disposed in the aging space 200 can be first aged to produce first aged meat (10, see FIG. 6 (b)).

In addition, the humidifier 400 may be controlled for secondary maturation by a wet-aging method by the control unit 600, which will be described later, so that the maturation space 200 is in a predetermined second humidity range. Here, the second humidity range may be 70% or more and 80% or less.

To this end, the reduction source 15 (see FIG. 7) along with the water described above may be further supported in the humidification tank (not shown) of the humidifier 400.

Accordingly, referring to FIG. 7, the humidifier 400 is disposed in the maturation space 200 by providing the reduction source 15 together with the moisture (hm) inside the maturation space 200. The surface of the first aged meat 10 can be humidified and coated with the reduction source 15 (see FIG. 8).

According to the present invention, as previously described with reference to FIG. 6 (b), while the meat (mt, see FIG. 4) is subjected to the first aging to produce the first aged meat 10, the In order to reduce the phenomenon of browning of the surface flesh color from the first color (cl1, see Figure 11 (a)), that is, red, to the second color (cl2, see Figure 11 (a)), that is, brown. It has been taken into consideration.

Specifically, referring to FIG. 8, when the reduction source 15 is humidified and coated on the surface of the first aged meat 10, the surface of the first aged meat 10 is formed through the second aging. and the reduction source 15 may react.

More specifically, referring to Figure 6 (b), as described above, the meat (mt, see Figure 4), before the aging, the first color (cl1, see Figure 11 (a)), that is, While the meat (mt, see FIG. 4) has a red color, as shown in FIG. 6 (a), during the first ripening, the surface (ox) of the meat (mt, see FIG. 4) Since oxymyoglobin (om) is oxidized (+O2) and converted into metmyoglobin (mm), the meat (mt, see FIG. 4) is produced by the first aging (10, FIG. 6). The surface (ox) flesh color (see (b)) may be browned to the second color (cl2, see FIG. 11 (a)), that is, brown.

However, as described above, according to an embodiment of the present invention, the reduction source (15, see FIG. 8) is the first ripened color having the second color (cl2, see FIG. 11 (a)), that is, brown color. When the first aged meat 10, which is humidified and coated on the surface of the meat 10 and humidified with the reduction source 15, is subjected to the second aging, during the second aging, in Figure 10 (a) As shown, metmyoglobin (mm) on the surface (re) of the first aged meat (10) reacts with the humidification-coated reduction source (15) and is reduced (-O2) to be converted into oxymyoglobin (om).

division	zest	six colors	moisture branch
Dry-aging day 1 (first aged meat)	6.0	9.1	9.0
Dry-aging day 3 (1st aged meat)	7.5	6.2	6.7
Dry-aging day 6 (1st aged meat)	9.0	2.5	2.4
Wet-aging day 1 (second aged meat)	9.0	3.5	3.6
Wet-aging day 3 (second aged meat)	9.0	7.3	7.5
Wet-Aging Day 7 (Second Aging Meat)	9.5	9.7	9.8

Referring to <Table 1> above, the sensory evaluation used a 10-point scoring method (2: very bad, 4: bad, 6: average, 8: good, 10: very good). In this case, the flavor and the moisture were evaluated after the aged meat was cooked by a recipe of simply applying heat without adding any seasoning and the evaluation group consumed each, and the meat color and the moisture were evaluated before the cooking. The evaluation was performed after the evaluation group observed the aged meat. In other words, the evaluation of moisture here is a result of combining the results of evaluation observed with the naked eye before cooking and the evaluation results of ingestion after cooking.
