Description

Technical Field

[0001] The present invention relates to a method for producing a placenta extract with reduced odor.

Background Art

[0002] Placenta extracts are used as materials for health foods, beauty cosmetics, pharmaceuticals, etc. This placenta extract is extracted from the placenta of horses, pigs, etc. (hereinafter referred to as "placenta"). The placenta is expelled from the mother as afterbirth during childbirth. Generally, the expelled placenta is collected, washed, and then, after undergoing enzymatic decomposition, the placenta extract is extracted, and finally the placenta extract is filtered. Thereafter, it may be used in a liquefied state or powdered. The expelled raw placenta is characterized by having a peculiar odor. In addition, since the expelled raw placenta contains blood, it is likely to deteriorate (rot), and if left unattended, the odor becomes stronger. Therefore, means for washing the raw placenta are taken as soon as possible after expulsion.

[0003] When performing enzymatic decomposition, water is to be mixed with the placenta. However, there is no determination of the amount of water to be added, and the placenta extract may become a highly concentrated one or a dilute one. For example, a method for producing a placenta extract having "an enzymatic decomposition step of adding an enzyme to the pre-treatment placenta to perform enzymatic decomposition, a placenta micronization extraction step of colliding the post-treatment placenta obtained in the enzymatic decomposition step at high speed to micronize placenta particles to extract fine placenta, and a filtration step of filtering the placenta extract from the fine placenta" has been proposed (see Patent Document 1). According to this production method, since the placenta particles are micronized in the placenta micronization extraction step, the amount of water used in the enzymatic decomposition step can be suppressed, and it is possible to obtain a highly concentrated placenta extract.

[0004] [Patent Document 1] Japanese Patent Publication No. 2015-33364 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] In the technology described in Patent Document 1, the vaporization of odor can be promoted and reduced by increasing the surface area through micronization of placenta. However, while it is possible to remove the odor generated from the placenta extract, it does not take into consideration the removal of the odor of the placenta extract itself. In other words, it is not possible to reduce the odor of the placenta extract itself.

[0006] The problem that this invention aims to solve is to provide a method for producing odorless placenta extract that makes it possible to remove the characteristic odor inherent in raw placenta itself that has been extracted late. [Means for solving the problem]

[0007] To solve the above problems, the method for producing odor-reduced placenta extract according to the present invention comprises an enzymatic decomposition step in which an enzyme is added to the placenta that has been excreted in the evening to perform enzymatic decomposition, and a lactic acid bacterial decomposition step in which lactobacilli are added to the placenta obtained in the enzymatic decomposition step to perform lactic acid bacterial decomposition.

[0008] With this configuration, the proteins in the placenta can be enzymatically broken down into low-molecular-weight peptides with excellent functionality and absorption through the above-mentioned steps. Furthermore, by breaking down the odor components of the placenta with lactobacillus, it is possible to remove the unique odor of placenta itself, making it widely usable as a material for medical products, food products, cosmetic products, etc. In the lactic acid bacteria decomposition step, for example, the placenta obtained in the enzymatic decomposition step can be sprayed with an aqueous solution containing lactobacillus to decompose it with lactobacillus, or the placenta obtained in the enzymatic decomposition step can be immersed once in an aqueous solution containing lactobacillus to decompose it with lactobacillus.

[0009] In the method for producing odor-reduced placenta extract according to the present invention, the configuration may include a post-decomposition freeze-drying step in which the placenta obtained in the lactic acid bacteria decomposition step is dried, following the lactic acid bacteria decomposition step.

[0010] With this configuration, after enzymatic and lactic acid bacterial decomposition, the resulting placenta can be freeze-dried to remove moisture, thereby improving the logistics efficiency of the placenta extract. Furthermore, subsequent processing of the placenta can be made simpler.

[0011] In the method for producing odor-reduced placenta extract according to the present invention, the configuration may include a powdering step in which the placenta obtained in the freeze-drying step after decomposition is powdered.

[0012] This configuration allows for the powdering of placenta extract, thereby improving the logistics efficiency of the placenta extract. Furthermore, because the placenta extract, whose quality has been improved through the above processes, is then powdered, it becomes highly versatile for use as an ingredient in health foods, cosmetics, pharmaceuticals, and other products.

[0013] In the method for producing odor-reduced placenta extract according to the present invention, the method includes a pre-decomposition freeze-drying step in which the placenta that has been exfoliated is dried before the enzymatic decomposition step, and in the enzymatic decomposition step, water is added to the placenta obtained in the pre-decomposition freeze-drying step to carry out the enzymatic decomposition.

[0014] With this configuration, the placenta, which has been excreted late, can have its moisture content reduced to almost zero in the pre-decomposition freeze-drying process before the enzymatic decomposition process. This reduces the effects of blood contained in the placenta (spoilage, denaturation, etc.). As a result, it is possible to suppress the unique odor of the placenta and prevent spoilage of the placenta. Consequently, the effectiveness of subsequent enzymatic and lactic acid bacterial decomposition processes is improved, and the quality is significantly enhanced. By reducing the odor components in the pre-decomposition freeze-drying process, it is also possible to shorten the processing time for subsequent lactic acid bacterial decomposition. Furthermore, since the placenta can be distributed in a freeze-dried state, logistics efficiency is also improved. Note that the freeze-drying process performed before the enzymatic decomposition process is called the pre-decomposition freeze-drying process, and the process performed after the lactic acid bacterial decomposition process is called the post-decomposition freeze-drying process.

[0015] In the method for producing odorless placenta extract according to the present invention, the configuration may include a washing step in which the placenta is washed before the enzymatic decomposition step.

[0016] This configuration helps to keep the placenta clean, preventing a decline in quality and further reducing the placental odor. [Effects of the Invention]

[0017] According to the present invention, by decomposing raw placenta through a lactic acid bacteria decomposition process, the odor components inherent in the placenta itself are broken down, so the characteristic odor of raw placenta is almost completely eliminated, and the versatility of placenta use can be increased.

Mode for Carrying Out the Invention

[0019] The method for producing a placenta extract with reduced odor according to the first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a flowchart showing the procedure flow of the method for producing a placenta extract with reduced odor (hereinafter referred to as "this manufacturing method") according to the embodiment of the present invention, Fig. 2 is a schematic diagram schematically showing the enzymatic decomposition step in the method for producing a placenta extract with reduced odor shown in Fig. 1, Fig. 3 is a schematic diagram schematically showing the lactic acid bacteria decomposition step in the method for producing a placenta extract with reduced odor shown in Fig. 1, Fig. 4 is a schematic diagram schematically showing the freeze-drying step after decomposition in the method for producing a placenta extract with reduced odor shown in Fig. 1, and Fig. 5 is a schematic diagram schematically showing the powdering step in the method for producing a placenta extract with reduced odor shown in Fig. 1.

[0020] In this embodiment, a process of extracting a solid (powder-like) placenta extract P4 from the placenta delivered from horses or pigs, that is, the pre-process placenta P0, is shown. The placenta means the placenta of mammals. In the following description, the delivered pre-process placenta is referred to as the pre-process placenta P0, the placenta obtained by enzymatically decomposing the pre-process placenta P0 is referred to as the enzymatically decomposed placenta P1, the placenta obtained by lactic acid bacteria decomposing the enzymatically decomposed placenta P1 with lactic acid bacteria is referred to as the lactic acid bacteria decomposed placenta P2, the placenta obtained by freeze-drying the lactic acid bacteria decomposed placenta P2 is referred to as the dried placenta P3, and the placenta obtained by pulverizing the dried placenta P3 is referred to as the powder placenta P4.

[0021] This manufacturing method is composed of a delivery step S01 of taking out the pre-process placenta P0, an enzymatic decomposition step S02 of enzymatically decomposing the pre-process placenta P0 into the enzymatically decomposed placenta P1, a lactic acid bacteria decomposition step S03 of lactic acid bacteria decomposing the enzymatically decomposed placenta P1 obtained in the enzymatic decomposition step S02 into the lactic acid bacteria decomposed placenta P2, a post-decomposition freeze-drying step S04 of freeze-drying the lactic acid bacteria decomposed placenta P2 obtained in the lactic acid bacteria decomposition step S03 into the dried placenta P3, and a pulverization step S05 of pulverizing the dried placenta P3 obtained in the post-decomposition freeze-drying step S04 into the powder placenta P4. Note that the pulverization step S05 is not an essential step in this manufacturing method. This is because the dried placenta P3 can be fully utilized as a placenta extract for materials such as health foods, beauty cosmetics materials, and pharmaceuticals. Pulverizing is for the convenience of use.

[0022] The delivery step S01 is usually carried out on a ranch or a pig farm. However, the delivery place is not particularly limited. It is preferable to wash the placenta delivered late before enzymatically decomposing it in the enzymatic decomposition step S02. The delivered raw placenta contains blood, so it is prone to spoilage and has the characteristic that the smell becomes stronger over time. Therefore, it is preferable to wash the raw placenta at the earliest possible stage after delivery.

[0023] In the enzymatic decomposition step S02, an enzymatic decomposition apparatus 10 is used. Placenta P0 before processing is placed in the enzymatic decomposition apparatus 10, enzyme E and water as needed are added, and the proteins in placenta P0 are enzymatically decomposed to obtain enzymatically decomposed placenta P1. This process is used to decompose the proteins in placenta into low-molecular-weight peptides with excellent absorption and functionality, in order to utilize placenta as a material for health foods, cosmetic ingredients, pharmaceuticals, etc. Enzyme E can be appropriately selected and used from, for example, plant-derived, microbial-derived, or animal-derived enzymes. In addition, if necessary, enzyme reaction aids such as pH adjusters and enzyme stabilizers may be added to the enzyme.

[0024] In the lactic acid bacteria decomposition process S03, a lactic acid bacteria decomposition device 20 is used. Enzyme-decomposed placenta P1 is placed in the lactic acid bacteria decomposition device 20, and an aqueous solution containing Lactobacillus L is sprayed directly onto it. Alternatively, the enzyme-decomposed placenta P1 may be immersed in the aqueous solution containing Lactobacillus L for a predetermined time. Lactobacillus, being a facultative anaerobic bacterium, is an organism that can produce energy regardless of the presence or absence of oxygen, and can switch between aerobic respiration (producing energy using oxygen) and anaerobic respiration (not producing energy using oxygen) depending on the availability of oxygen in the environment. Therefore, it can efficiently decompose the components that produce the characteristic odor of placenta, and thus remove the odor. In the lactic acid bacteria decomposition process S03, in order to efficiently perform lactic acid bacteria decomposition, the moisture content, pH, and temperature inside the lactic acid bacteria decomposition device 20 are kept within a predetermined range suitable for lactic acid bacteria decomposition, for example, for several hours to several days. This allows for the enzyme-degraded placenta P1 to be degraded by lactic acid bacteria in the lactic acid bacteria decomposition step S03 to obtain lactic acid bacteria-degraded placenta P2.

[0025] In the freeze-drying process S04 after decomposition, a freeze-drying apparatus 30 is used. Lactic acid bacteria-decomposed placenta P2 is freeze-dried in the freeze-drying apparatus 30. In the freeze-drying apparatus 30, the lactic acid bacteria-decomposed placenta P2 containing water is rapidly frozen to about -30°C, and the water contained in the lactic acid bacteria-decomposed placenta P2 is sublimated by creating a vacuum state through reduced pressure. In this way, the lactic acid bacteria-decomposed placenta P2 can be dried. Water turns into a gas regardless of temperature when the pressure approaches a vacuum state due to reduced pressure, so when the pressure is sufficiently reduced while the lactic acid bacteria-decomposed placenta P2 is frozen, the water contained in the lactic acid bacteria-decomposed placenta P2 changes into a gas and is released to the outside of the lactic acid bacteria-decomposed placenta P2. Through this action, only the water contained in the lactic acid bacteria-decomposed placenta P2 can be removed and it can be dried. Since only the water can be removed, a high-concentration placenta extract can be obtained.

[0026] In the powdering process S05, a powdering device 40 is used. Dried placenta P3 is placed in the powdering device 40 and powdered into powdered placenta P4 by the high-speed pulverizing blades of the powdering device 40. Depending on the type of pulverizing blades of the powdering device 40, powdered placenta P4 can be obtained according to the application, such as coarse powder or fine powder. Note that the powdering device 40 is not limited to the above, and for example, a device that powders by impact with a high-speed gas flow may also be used.

[0027] According to this embodiment, although untreated placenta P0, which is the placenta delivered before processing, has a characteristic odor, the method for producing placenta extract with reduced odor includes a lactic acid bacteria decomposition step in which Lactobacillus decomposes the odor components. As a result, the odor-causing components themselves can be broken down, making it possible to widely use the placenta extract as a material for health foods, cosmetic ingredients, pharmaceuticals, etc.

[0028] Next, a method for producing odor-reduced placenta extract according to a second embodiment of the present invention will be described with reference to Figure 6. As shown in Figure 6, the difference between the second embodiment and the first embodiment is that a pre-decomposition freeze-drying step S12 is added before the enzymatic decomposition step S13. In the second embodiment, the production process for odor-reduced placenta extract is sequentially comprised of a late-release step S11, a pre-decomposition freeze-drying step S12, an enzymatic decomposition step S13, a lactic acid bacteria decomposition step S14, a post-decomposition freeze-drying step S15, and a powdering step S16. Except for the newly added pre-decomposition freeze-drying step S12, each step is carried out using the same apparatus and in the same manner as shown in the first embodiment.

[0029] In the pre-decomposition freeze-drying step S12, the freeze-drying apparatus 30 used in the post-decomposition freeze-drying step S15 can be used. It is also possible to use a freeze-drying apparatus other than the one used in the post-decomposition freeze-drying step 30. Normally, pre-processed placenta P0 is not freeze-dried before the enzymatic decomposition step. This is because freeze-drying requires a lot of electricity, resulting in very high electricity costs, making it impractical as a method for producing placenta extract with reduced odor. However, in this method, by freeze-drying pre-processed placenta P0, it becomes possible to reduce the characteristics of raw placenta (such as the generation of a distinctive odor and its susceptibility to spoilage). In other words, this method allows for the near-zero reduction of water content (including blood) in the placenta, thereby mitigating the effects of blood. Therefore, it becomes possible to eliminate almost all of the placental odor. Furthermore, spoilage of the placenta can be suppressed. Moreover, since the placenta can be transported in a freeze-dried state, logistics efficiency is improved. Additionally, dried placenta can be used during enzymatic decomposition. Therefore, the ease of handling the placenta is improved. Furthermore, by providing a pre-decomposition freeze-drying step S12 to remove moisture, most of the odor components can be removed, and in combination with the subsequent lactic acid bacteria decomposition step S14, the removal of odor components can be thoroughly achieved. As a result, it becomes possible to provide a high-quality placenta extract with reduced odor. Moreover, by providing a pre-decomposition freeze-drying step S12 to remove odor components, the time required for lactic acid bacteria decomposition can be shortened. In the second embodiment, the untreated placenta P0 is processed in order into dried placenta P01, enzyme-decomposed placenta P02, lactic acid bacteria-decomposed placenta P03, dried placenta P04, and powdered placenta P05.
