<< Method for producing eggshell membrane lot >>
The production method of the eggshell membrane lot according to the present embodiment includes the eggshell membrane-prepared step of preparing the eggshell membrane-attached eggshell by dividing the eggs and removing the egg white and egg yolk from the inside of the eggshell, and the eggshell membrane from the eggshell membrane-attached eggshell membrane The eggshell membrane lot manufacturing method includes an eggshell membrane separation step of separating an eggshell membrane using a specific gravity difference between a shell and an eggshell to obtain an eggshell membrane. In the eggshell membrane separation step, the raw material lot corresponding to the eggshell membrane lot and composed of a plurality of eggshell membrane-attached eggshells, and eggshell membrane-attached eggshells obtained by dividing 64 g or more eggs are 85% by number or more. Raw material lots containing 95% or less are used. Hereinafter, each step will be described in detail.

<Egg shell preparation process with eggshell membrane>
In the eggshell preparation step with eggshell membranes, the egg white and egg yolk are removed from the eggshell and the eggshell with eggshell membrane is prepared.
Eggs that are split in the eggshell preparation step with eggshell membranes (chicken eggs) are particularly limited except that they include both L-sized eggs (64 g or larger eggs) and L-sized eggs (64 g or smaller eggs). Not. “SS size” of 40 g or more and less than 46 g, “S size” of 46 g or more and less than 52 g, “MS size” of 52 g or more and less than 58 g, “M size” of 58 g or more and less than 64 g, 64 g or more and less than 70 g A raw egg lot in which “L size” or “LL size” of 70 g or more and less than 76 g is mixed may be used. For example, you may perform the eggshell preparation process with eggshell membranes with respect to the raw material egg lot which consists of L size eggs and S size eggs. A “raw material egg lot” is an aggregate of eggs that are composed of a plurality of eggs and that are subjected to a continuous or identical eggshell membrane-attached eggshell preparation step. When using a plurality of raw egg lots, all raw egg lots may contain eggs of L size or larger and less than L size, but all raw egg lots are of L size or larger and smaller than L size. For example, it is sufficient if there are at least one raw material egg lot containing eggs of L size or larger and one or more raw material egg lots containing eggs of less than L size among a plurality of raw material egg lots.

  By splitting eggs, about 2 to 3 pieces of eggshell membrane-attached eggshells, which are eggshells with the eggshell membranes on the inner surface, are obtained. In addition, in this specification, the number in number% is converted into an egg. For example, when two eggshells with eggshell membranes are obtained by dividing one egg, 1 Count as a piece. Further, egg white and egg yolk removed from the eggshell by being divided are collected and used as food or the like.

  The eggshell with eggshell membrane obtained by splitting eggs is preferably washed with a washing solution such as water to remove the attached egg solution. Moreover, it is preferable to dry after washing.

<Egg shell membrane separation process>
In the eggshell membrane separation step, the eggshell membrane is obtained by separating the eggshell membrane from the eggshell membrane-attached eggshell obtained in the eggshell membrane-attached eggshell preparation step using the specific gravity difference between the eggshell membrane and the eggshell.
The eggshell membrane separation process may include a specific gravity difference separation process that separates the eggshell membrane using the specific gravity difference between the eggshell membrane and the eggshell, but before the specific gravity difference separation process, the eggshell membrane is attached as necessary. It has a crushing process for crushing eggshells, an ultrasonic irradiation process for irradiating ultrasonic waves, a sorting process with a sieve, and the like. Moreover, you may have a sterilization process and a drying process suitably.

  In the eggshell membrane separation step according to the present embodiment, the eggshell membrane eggshell corresponding to the eggshell membrane lot and composed of a plurality of eggshell membrane-attached eggshells, and having eggshell membranes formed by dividing 64 g or more eggs. Using raw material lots contained in a number of not less than 95% and not more than 95%, eggshell membrane lots are obtained by separating eggshell membranes using the specific gravity difference between eggshell membranes and eggshells.

  A “raw material lot” is an assembly of a plurality of eggshell membrane-attached eggshells that are composed of a plurality of eggshell membrane-attached eggshells and are subjected to continuous or the same eggshell membrane separation process. An “eggshell membrane lot” is an aggregate of a plurality of eggshell membranes composed of a plurality of eggshell membranes. An eggshell membrane lot is obtained by subjecting the raw material lot to an eggshell membrane separation step to separate the eggshell membrane. That is, the raw material lot corresponds to an eggshell membrane lot obtained from the raw material lot.

  By using a raw material lot in which eggshell membrane-attached eggshells obtained by splitting eggs of 64 g or more in the eggshell membrane separation step are contained in an amount of 85 to 95% by number, an eggshell membrane can be obtained simply and efficiently. Although it may be 85% by number or more and 95% by number or less, it is preferably 90% by number or more. Moreover, it is preferable that it is 93 number% or less.

As shown in the experimental examples to be described later, the eggshell membrane-attached eggshell obtained by dividing an egg of L size or larger (a chicken egg of 64 g or more) is more than the eggshell membrane-attached eggshell obtained by breaking an egg of less than L size, The yield of eggshell membrane is high. This is presumed to be because the larger eggs have a larger radius of curvature than the smaller eggs, and the buoyancy of the crushed eggshell membrane-attached eggshell is easy to work without escaping in water, and the eggshell membrane is easily peeled off. Therefore, by using a raw material lot that contains 85% by number or more of eggshells with eggshell membranes formed by breaking eggs of 64 g or more, the yield of eggshell membranes obtained can be increased, and eggshell membranes can be obtained efficiently. it can. According to the applicant's investigation, the abundance rate of eggs having an average value of L size or more in the past several years is about 75% by number, and the abundance rate of eggs having a size less than L size is about 25% by number. Therefore, it is considered that the yield of eggshell membranes can be reliably increased by using a raw material lot containing 85 shells or more of eggshell membrane-attached eggshells obtained by breaking eggs of 64 g or more. . However, there is no enormous difference between the yield of eggshell membranes with eggshell membranes obtained by splitting eggs larger than L size (64 g or more chicken eggs) and the yield of eggs smaller than L size. Considering that usually many eggs are present, eggs of less than L size are contained in an amount of 5% to 15% by number, that is, the ratio of eggshells with eggshell membranes obtained by dividing an egg of 64g or more is 95. It is necessary to use raw material lots having a number% or less from the viewpoint of balance between yield and yield. The “yield of eggshell membrane” is a mass-based ratio of the eggshell membrane lot obtained from the raw material lot to the raw material lot used in the eggshell membrane separation step.
In addition, by managing the manufacturing process using lots (aggregates) such as raw material lots and eggshell membrane lots, the manufacturing process can be simplified and made more efficient.

  Here, the raw material lot used in the eggshell membrane separation step may not correspond to the raw material egg lot used in the eggshell membrane-attached eggshell preparation step performed before the eggshell membrane separation step. For example, a combination of at least a part of eggshells with eggshell membranes obtained from one raw material egg lot and at least a part of eggshells with eggshell membranes obtained from another raw material egg lot, or obtained from one raw material egg lot A part of the eggshell membrane-attached eggshell obtained can be used as a raw material lot used in the eggshell membrane separation step.

  The raw material lot used in the eggshell membrane separation step may not be selected based on the number of days until egg breaking after egg laying. The present inventors have also found that the yield of eggshell membranes does not substantially change depending on the number of days until egg breaking after spawning. The manufacturing method of the eggshell membrane lot of the embodiment becomes simpler.

  In addition, the raw material lot used in the eggshell membrane separation step may include 35% by number or more of eggs whose number of days until egg breaking after egg laying is 4 days or more. The yield of eggshell membranes does not change substantially depending on the number of days until egg laying after egg laying. Therefore, a raw material lot containing 35% by number or more of eggs whose number of days until egg breaking after egg laying is 4 days or more is included. It may be used. Although the upper limit of the ratio in which the number of days until egg breaking after egg-laying is 4 days or more is included is not specifically limited, For example, it is 50 number% or less. By using a raw material lot that contains 35% or more of eggs that are 4 days or longer after egg laying, it is possible to implement this even when the egg-laying place is relatively far from the egg-breaking place. It is possible to apply a method for producing an eggshell membrane lot with a good yield in the form of By using a raw material lot that contains 35% or more of eggs that are 4 days or longer after egg laying, the number of days until egg breaking after egg laying can be used. It can be said that the eggshell membrane manufacturing method of the present embodiment can be applied in an environment.

(Crushing process)
In the pulverization step, the eggshell with eggshell membrane obtained in the eggshell preparation step with eggshell membrane is pulverized.
By pulverizing the eggshell with the eggshell membrane, the eggshell membrane is peeled off from the eggshell, or the eggshell membrane is easily peeled off from the eggshell.
The method for pulverizing the eggshell with the eggshell membrane is not particularly limited as long as the eggshell can be pulverized. For example, it can grind | pulverize using grinders, such as a miller. The pulverization may be dry or wet pulverized in a liquid or the like.
In addition, in the eggshell membrane-attached eggshell obtained in the eggshell membrane-attached eggshell preparation step, if the eggshell membrane is easily peeled off, the crushing step may not be performed.

(Ultrasonic irradiation process)
The ultrasonic irradiation step is provided as necessary after the crushing step, and irradiates the eggshell with eggshell membrane after the crushing step with ultrasonic waves. By irradiating the eggshell with eggshell membranes with ultrasonic waves, the eggshell membrane can be peeled from the eggshell membrane-attached eggshell after the crushing process, or can be made more easily peeled off. .

(Separation process by sieve)
The separation process using a sieve is provided as necessary after the pulverization process, and the eggshell and the eggshell membrane peeled off from the eggshell are separated using a sieve. In this embodiment, the eggshell membrane is separated using the specific gravity difference between the eggshell membrane and the eggshell, but by providing a separation step using a sieve as the pretreatment, the specific gravity difference between the eggshell membrane and the eggshell is used. The amount of processing in the step of separating the eggshell membrane can be reduced.

(Specific gravity difference separation process)
After the eggshell with eggshell membrane obtained in the eggshell preparation step with eggshell membrane is subjected to pulverization treatment, ultrasonic irradiation treatment, and fractionation treatment with a sieve as necessary, the eggshell membrane and eggshell in the specific gravity difference separation step The eggshell membranes are separated using the difference in specific gravity.
The method of separating the eggshell membrane using the difference in specific gravity between the eggshell membrane and the eggshell is not particularly limited, for example, the eggshell with eggshell membrane obtained in the eggshell membrane preparation step with the eggshell membrane is pulverized as necessary. After performing an ultrasonic irradiation treatment or a fractionation process with a sieve, it may be put into a liquid such as water as in Patent Document 1 and the eggshell may be naturally settled and separated, or a liquid cyclone as in Patent Document 2 For example, the centrifugal separation may be used for sedimentation separation, or as disclosed in Patent Document 3, the separation may be performed using an air stream. Specifically, for example, the eggshell membrane-attached eggshell obtained in the eggshell membrane-attached eggshell preparation step is subjected to pulverization treatment, ultrasonic irradiation treatment, or fractionation treatment with a sieve as necessary, and then into a liquid such as water. The collected eggshell is allowed to settle, and the eggshell membrane is allowed to float and the eggshell membrane is floated, and the floated eggshell membrane is allowed to overflow. As described above, since the method of separating the eggshell membrane using the specific gravity difference between the eggshell membrane and the eggshell is a simple method, the manufacturing method of the eggshell membrane lot of the present embodiment is also a simple method.

  Thus, according to the eggshell membrane lot manufacturing method of the present embodiment, an eggshell membrane can be obtained simply and efficiently. The obtained eggshell membrane can be used, for example, as a therapeutic agent for skin diseases. Moreover, you may use the eggshell from which the eggshell membrane was isolate | separated as a manufacturing raw material of egg related products other than an eggshell membrane.

<< Method for producing egg-related product group >>
The method for manufacturing an eggshell membrane lot according to the present embodiment is a method for manufacturing an egg-related product group including an eggshell membrane lot and an egg-related product other than the eggshell membrane. And the eggshell membrane lot manufacturing process for manufacturing the eggshell membrane lot by the above-described eggshell membrane lot manufacturing method, and the eggshell membrane-attached eggshell that is not included in the raw material lot among the eggshell membrane-attached eggshell prepared in the eggshell membrane-attached eggshell preparation step And an egg-related product manufacturing process for obtaining an egg-related product other than eggshell membranes from at least a part. Hereinafter, although each process is demonstrated in detail, the description which overlaps with said <<< the manufacturing method of eggshell membrane lots>, such as a manufacturing method of eggshell membrane lots, an eggshell preparation process with eggshell membranes, is abbreviate | omitted.

<Egg-related product manufacturing process>
In the egg-related product manufacturing process, an egg-related product other than the eggshell membrane is obtained from at least part of the eggshell with eggshell membrane that is not included in the raw material lot among the eggshell with eggshell membrane prepared in the eggshell membrane with eggshell preparation step.

  Egg-related products other than eggshell membranes are products other than eggshell membranes that can be produced from eggshells with eggshell membranes. Examples of egg-related products other than eggshell membranes include calcium carbonate-containing products such as chalk and fertilizer obtained from eggshell.

In the egg-related product manufacturing process, at least part of the eggshell with eggshell membrane that is not included in the raw material lot among the eggshell with eggshell prepared in the eggshell with eggshell preparation process is used.
More specifically, in the egg-related product manufacturing process, the eggshell membrane with eggshell membrane formed by splitting eggs of 64 g or more, which is the raw material lot used in the eggshell membrane separation step, of the eggshell with eggshell membrane prepared in the eggshell membrane preparation step Egg shells with eggshell membranes other than raw material lots containing 85% to 95% by number of eggshells are used.
In this way, by using at least a part of the eggshell with eggshell membrane not included in the raw material lot used in the eggshell membrane separation step among the eggshell with eggshell membrane prepared in the eggshell membrane preparation step, the eggs are divided into eggshells. From egg shells with eggshell membranes obtained by removing (collecting) egg whites and yolks from eggs, not only eggshell membranes can be efficiently produced, but also eggs-related products other than eggshell membranes from eggshells with eggshell membranes that are not used for the production of eggshell membranes Can be manufactured. Therefore, the egg shell with eggshell membranes obtained by splitting eggs and removing (collecting) egg white and egg yolk from the inside of the eggshell can be used very effectively.

Specific examples of the method for manufacturing the eggshell membrane lot and the method for manufacturing the egg-related product group described above will be described with reference to the drawings. FIG. 1 is a flow showing an example of a method for producing an eggshell membrane lot of the present invention. In FIG. 1, a raw material egg lot 1 composed of only a plurality of L size eggs, a raw material egg lot 2 composed of only a plurality of S size eggs, a plurality of L size, M size, MS size and S size. The raw material egg lot 3 composed of the eggs is used.
As shown in FIG. 1, first, in the eggshell membrane-attached eggshell preparation step, each of the raw egg lots 1 to 3 is divided and the egg white and egg yolk are removed from the inside of the eggshell to obtain an eggshell with eggshell membrane.
Next, in FIG. 1, an egg of 64 g or more is formed by a part of an eggshell with eggshell membrane formed by dividing raw egg lot 1 and a part of an eggshell with eggshell membrane formed by dividing raw egg lot 2 Raw material lot 1 containing eggshell membrane-attached eggshells obtained by splitting eggs in the range of 85 to 95% by number is prepared.
Then, this raw material lot 1 is subjected to an eggshell membrane separation step, and the eggshell membrane is separated from the eggshell with eggshell membrane (raw material lot 1) by utilizing the difference in specific gravity between the eggshell membrane and the eggshell. )
On the other hand, the remainder of the egg shell with eggshell membrane formed by dividing raw egg lot 1, the remainder of the eggshell with eggshell membrane formed by dividing raw egg lot 2, and the eggshell membrane formed by dividing raw egg lot 3 Raw material lot 2 is prepared with an egg shell.
And this raw material lot 2 is used for an egg related product manufacturing process, and egg related products other than eggshell membrane are obtained.

  Below, eggshell membranes with eggshell membranes obtained by dividing eggs of L size or larger (64 g or more of chicken eggs), which are findings in the present invention, are less than L size (for example, S size) eggs (chicken eggs of less than 64 g). In addition, experimental examples showing that the yield of eggshell membranes is high and that the yield of eggshell membranes do not substantially change depending on the number of days until egg breaking after egg laying are shown.

[Example 1] L size The following operations were performed for different raw material egg lots 1-1 to 1-6 as a raw material egg lot 1 composed of only a plurality of L size eggs.
(Preparation of eggshell with eggshell membrane)
A raw material egg lot 1 composed of only a plurality of L-sized eggs is prepared. The eggs constituting the raw material egg lot 1 are those having a period of 3 days until egg breaking after egg laying.
Next, in the eggshell preparation step with eggshell membrane, the eggs constituting the raw egg lot 1 are divided into two, and after removing the egg white and yolk from the inside of the eggshell, the egg white adhering to the eggshell is removed by washing with water. Get a sticky eggshell.
(Separation of eggshell membranes)
The obtained eggshell with membrane is crushed to about 2 mm square using Iwatani CRUSH MILSER IFM-C20G, and then passed through a sieve (a sieve having a 10 mm diameter circular hole).
300g (dry mass 256.8g, moisture 43.2g) that passed through the sieve was put into a 5L stainless steel can, and water was poured into the stainless steel can and stirred with a stirrer. By floating a light eggshell membrane and overflowing water, the eggshell membrane is separated and recovered and dried.
The equipment and conditions used are as follows.
Moisture analyzer: Kett Scientific Laboratory, infrared moisture meter kett FD-620
Stirrer: manufactured by ASONE, AS ONE SMT-103
Stirrer: HEIDON Kai Cross R, manufactured by Shinto Kagaku
Stirring speed: 400rpm
Egg shell membrane recovery time: 6 minutes Stainless steel can: 5 L stainless steel can (diameter: about 18 cm x height: about 22 cm)
Inflow of water: 6L / min (recovered egg shell membrane)
Table 1 shows the total mass (dry mass) of the recovered eggshell membranes.

[Example 2] S-sized raw material egg lot 2 composed only of a plurality of S-sized eggs instead of the raw material egg lot 1 composed of only a plurality of L-sized eggs (different raw material egg lots 2-1 to 2) About 6-6, it carried out similarly to Example 1 except having performed each. The results are shown in Table 2.

When tested by t-test, there is a significant difference at a risk rate of 5% (p = 0.034 <0.05), and the recovery amount of eggshell membranes in L size (Table 1) is the same as that of eggshell membranes in S size. It was higher than the recovered amount (Table 2). Therefore, it can be said that the L size has a higher yield than the S size. However, the difference in yield between the L size and the S size was not enormous enough to throw away the ones smaller than the L size.
In addition, the eggshell membrane is separated by putting it into a 5 L stainless steel can, flowing water into the stainless steel can and stirring it with a stirrer, allowing the eggshell to settle, floating the eggshell membrane with a light specific gravity, and overflowing the water. -In the case of separating with a hydrocyclone or wind power separator instead of the collecting operation, the yield of the L size was higher than that of the S size as in [Example 1] and [Example 2].

[Example 3] L size It was the same as Example 1 except that the number of days until egg breaking after egg laying was 1, 2 or 10 days. The results are shown in Table 3.
As shown in Table 3, the amount of eggshell membranes recovered did not change depending on the number of days until egg breaking after egg laying.

[Example 4]
The eggshell membranes that could not be recovered due to overflow (eg the eggshell membranes that were not peeled off from the eggshell) were also manually separated and recovered in the same manner as in [Example 1].
The total of the eggshell membranes collected manually and the eggshell membranes recovered by overflow was taken as the amount of eggshell membrane. The results are shown in Table 4.

[Example 5]
The eggshell membrane that could not be recovered due to overflow (eg, the eggshell membrane that was not peeled off from the eggshell) was manually separated and recovered, and the procedure was the same as in Example 2.
The total of the eggshell membranes collected manually and the eggshell membranes recovered by overflow was taken as the amount of eggshell membrane. The results are shown in Table 4.
As shown in Table 4, the amount of eggshell membranes recovered did not change between L size and S size. Therefore, the ratio of the eggshell membrane contained in the eggshell with eggshell membrane does not change depending on the size of the egg, and the difference in yield depending on the size of the eggs shown in Examples 1 and 2 depends on the raw material lot used in the eggshell membrane separation process. It was confirmed that it depends on the difference.
