Description

  The present invention relates to a method for producing a fish nasal cartilage product obtained from fish nasal cartilage such as salmon and coral, and in particular, a method for producing a fish nasal cartilage product obtained by drying nasal cartilage extracted from a fish head. About.

  Conventionally, for example, in sharks as fish, the nasal cartilage has many proteoglycans that are complex of sugar and protein, and this proteoglycan contains chondroitin sulfate, which is an acidic mucopolysaccharide. There is a technique for producing a nasal cartilage product obtained by extracting and drying nasal cartilage from salmon fish heads.

  Proteoglycan promotes proliferation of epidermal cells, promotes hyaluronic acid and collagen production, promotes cartilage regeneration, relieves symptoms such as osteoarthritis, suppresses inflammation in the human body, and is a lifestyle-related disease In recent years, nasal cartilage products have been widely used for medicines, cosmetics, foods, and the like because they have various effects such as prevention and improvement of obesity and diabetes.

  Conventionally, as a method for producing a fish nasal cartilage product, for example, a technique disclosed in Japanese Patent No. 5252623 is known. This is done by freezing nasal cartilage previously removed from the fish head of the carp, crushing the frozen carp nasal cartilage, adding water to this, stirring the mixture, centrifuging the mixture with a centrifuge, Separate proteoglycan and other compositions. Next, the uppermost lipid layer and the intermediate aqueous layer are removed, and a precipitate is collected. The precipitate is freeze-dried and then pulverized with a centrifugal pulverizer to obtain a water-defatted fine powder. Thereafter, ethanol is added to the water-defatted fine powder to dissolve and extract the lipid, the ethanol solution is removed by filtration, the solvent is evaporated, the lipid removal rate is set to 98% to 100%, and the proteoglycan composition having substantially zero lipid. Obtain powder to make nasal cartilage products.

Japanese Patent No. 5252623

  By the way, in this conventional method for producing a nasal cartilage product, the whole nasal cartilage of salmon is used. In the whole nasal cartilage, the amount of lipid is 4.6 g / 100 g in a wet state and 35 in a dry state. .1g / 100g (see Table 1 of Patent Document 1), so in order to remove this lipid, the frozen carp nasal cartilage was crushed and mixed with water, and this mixture was centrifuged with a centrifuge. Separated, and further dissolved in ethanol, there was a problem that the production was complicated and the production efficiency was impaired because the lipid removal step was provided. If the process of extracting the nasal cartilage is included in advance, the production efficiency is further deteriorated. In addition, in nasal cartilage products, it is desirable to have as little lipid as possible. However, there is a situation where the products can be used as products even if the lipid removal rate is not set to 98% to 100% as in the prior art.

  The present invention has been made in view of the above-mentioned problems. By extracting nasal cartilage and not containing a considerable amount of lipid, fish nasal cartilage products can be manufactured to improve manufacturing efficiency. It is an object of the present invention to provide a method for producing nasal cartilage products of fish.

The inventor of the present application has found that the posterior side lipid component is relatively low in the nasal cartilage of salmon and that a considerable amount of lipid is removed by the method of extraction processing based on many years of research, and the present invention has been completed. I let you.
That is, in order to achieve the above object, a method for producing a fish nasal cartilage product according to the present invention is a fish nasal cartilage product production method for producing a nasal cartilage product obtained by drying nasal cartilage on a fish head. fish head, to extract the rear side portion of the rear side including the front end position location of the eyes of the nasal cartilage, the rear side of the nose cartilage said extract has a lower inter cartilage located on the lower side between the eyes An upper cartilage provided so as to cover both eyes and the brain, the upper cartilage being a lid-like cartilage on the upper side of the pituitary and an upper side in front of the lid-like cartilage It comprises an anterior cartilage, a pair of upper lateral cartilage on both sides of the lid-like cartilage and the upper anterior cartilage, and an upper posterior cartilage on the rear side of the lid-like cartilage, and the posterior side is dried It is configured to do.

  Thus, for example, in the case of sea bream as fish, as will be apparent from the analysis results described later, there is little lipid on the posterior side of nasal cartilage, so if this posterior part is extracted and dried, it is extremely lipid. A nasal cartilage product with low content can be obtained. In other words, it is possible to produce fish nasal cartilage products by extracting only the posterior side of the nasal cartilage and not containing a considerable amount of lipid, and the conventional complicated processing after extraction can be omitted as in the past. , Manufacturing efficiency can be improved. The nasal cartilage product is not zero in lipids, but can be used for various foods as it is. Of course, as in the prior art, a purification treatment may be carried out so as to make the lipid substantially zero by performing a dissolution treatment with ethanol.

  In this case, the posterior side of the nasal cartilage is configured to include a lower interstitial cartilage positioned below the both eyes and an upper cartilage provided to cover both eyes and the brain, and the lower interstitial cartilage It is also effective to extract and dry the upper cartilage. In general, when removing nasal cartilage, there is a large amount of upper cartilage of nasal cartilage provided so as to cover both eyes and the brain. Therefore, the lower interstitial cartilage on the lower side is discarded. However, in the present invention, this lower interstitial cartilage is also taken out. Therefore, the recovery rate of nasal cartilage is improved.

  And it is set as the structure provided with the parting process which divides the front side part of a nasal cartilage, and the rear side part of a nasal cartilage as needed, and the freeze-drying process which freeze-drys the back side part of a nasal cartilage by freeze drying. The rear side is taken out as it is, or taken out in several chunks. This can be freeze-dried as it is. When the posterior mass of nasal cartilage is freeze-dried, handling becomes easy. Further, it may be crushed and reduced in size and then lyophilized. The posterior side of the nasal cartilage has a water content of 85% by weight or more, and when the mass is freeze-dried, it becomes a porous brittle mass. This mass can be distributed as a nasal cartilage product.

  Further, if necessary, in the cutting step, the fish head is divided into a fish head upper part including nasal cartilage and a fish head lower part not including nasal cartilage, and the fish head upper part includes a front side part of nasal cartilage. Divide into an anterior part of the fish head and an posterior part of the fish head including the posterior side of the nasal cartilage, and put the posterior part of the fish head separated in the dividing step into water of less than 100 ° C. to remove the excess part including the fleshy part and the normal bone. The extraction step of removing and extracting the posterior side of the nasal cartilage is employed.

  Thus, in the cutting step, the entire nasal cartilage is extracted from the fish head, and then the nasal cartilage is separated by dividing the fish head itself, rather than dividing the nasal cartilage into the front side portion and the rear side portion. Since it is divided into anterior and posterior parts, when extracting the posterior part of nasal cartilage, it is possible to divide the fish head without removing extraneous parts including fleshy parts and normal bones from the entire fish head. Since it is only necessary to remove the extra part including the fleshy part and the normal bone from the rear upper part of the fish head which is smaller than the whole fish head, the extra part can be removed less, and therefore the processing efficiency can be greatly improved. Further, the upper front part of the fish head including the front side part of the nasal cartilage is left as it is without removing the fleshy part, so that, for example, it can be made into a processed product such as icy salmon sliced from this part.

  Also, in the extraction process, the upper rear part of the fish head is put into water at less than 100 ° C., and the extraneous part of the meat part and the normal bone is removed. Since the lipid dissolves into the water, the posterior side of the nasal cartilage with less lipid can be extracted. Furthermore, since it is treated with water at a temperature of 100 ° C. or lower, degeneration of nasal cartilage is prevented.

Further, if necessary, in the extraction step, the lower cartilage, the superior anterior cartilage, the pair of superior transverse cartilage, and the superior posterior cartilage are extracted from the posterior side portion, and the lyophilization step In this case, it is effective to dry the lower interstitial cartilage, superior anterior cartilage, a pair of superior transverse cartilage, and superior posterior cartilage.
Furthermore, if necessary, the extraction step includes the posterior side of the nasal cartilage in which the upper part of the fish head is placed in water at 70 ° C. to 95 ° C. and stirred for the required time to remove as much meat as possible. A pretreatment step for obtaining an intermediate, and the intermediate obtained in the pretreatment step are placed in water at 25 ° C. to 50 ° C., and an extra portion including a fleshy part and normal bone is removed from the intermediate to remove nasal cartilage The present processing step for extracting the posterior side portion and the finishing step for washing the posterior side portion of the extracted nasal cartilage with cold water are employed.

  In the pretreatment step, the meaty portion is removed as much as possible from the upper rear portion of the fish head, so that the intermediate can be handled easily and the treatment can be facilitated. In this case, since the posterior side of the nasal cartilage is treated with a relatively hot water of 70 ° C. to 95 ° C., the fleshy part is easily peeled off from the nasal cartilage, and the processing efficiency is improved accordingly. Moreover, in this temperature range, the number of general viable bacteria can be reduced.

  Further, in this processing step, the posterior side of the nasal cartilage is treated with relatively warm water of 25 ° C. to 50 ° C., for example, when removing these extra portions manually, the workability is good. Further, since the lipid is dissolved in water, the posterior side of the nasal cartilage with less lipid can be extracted. Furthermore, since it is treated with water at a temperature of 100 ° C. or lower, degeneration of nasal cartilage is prevented. Furthermore, since the posterior side of the nasal cartilage is washed in the finishing process, the remaining excess portion is surely removed. Further, the adhesion of impurities can be prevented.

  In this case, in the main treatment step, the intermediate is placed in a net-like cocoon, the cocoon is immersed in a container containing water at 25 ° C. to 50 ° C., and the nasal cartilage is manually placed in the cocoon. It is effective that the side portion is extracted and the water in the container is replaced a plurality of times. As a result, it is possible to remove the extra part including the fleshy part and the normal bone from the intermediate by repetitively squeezing the intermediate in the bag by hand. The removed excess can be drained into the water through the eyelets. If bones attached to the nasal cartilage are removed, they are discarded outside the cage. Since the water in the container is changed a plurality of times, the removal operation can be repeated until the water in the container is no longer dirty. In this case, the extra part can be removed by touching it with the hand, so that the extra part can be surely removed as compared with mechanical processing, and the posterior side of pure nasal cartilage is extracted be able to. In addition, since the surface of the posterior side of the nasal cartilage is traced by hand, the lipid can be easily dissolved into the water from the surface of the nasal cartilage. Also in this respect, the posterior side of the nasal cartilage with less lipid can be extracted. .

In this case, the upper Symbol this process step, from the rear side, except for the cap-like cartilage, the lower inter cartilage, upper front cartilage, a pair of upper lateral cartilage extracts rear upper cartilage, in the finishing step The inferior interchondral cartilage, superior anterior cartilage, a pair of superior lateral cartilage, and superior posterior cartilage are washed, and in the lyophilization step, the inferior cartilage, superior anterior cartilage, pair of superior transverse cartilage and superior posterior cartilage are lyophilized. It is effective to do.

  In the posterior side of the nasal cartilage, the inferior mesothelial cartilage, the cricoid cartilage, the superior anterior cartilage, the pair of superior transverse cartilage, and the superior posterior cartilage are connected to each other so as to be separable from each other. When force is applied by pushing or pulling on, it is easily separated into individual lumps. Therefore, each part can be processed individually. Further, the upper lid-like lid cartilage can be easily removed. Since the lid-like cartilage is a portion that is relatively hard and the lipid component is difficult to flow out, by removing this, the lipid component of the nasal cartilage product can be reduced and the quality can be further improved.

  And if needed, it is set as the structure provided with the grinding | pulverization process which makes a dried material a powder with a particle size of 1 mm or less after the said freeze-drying process. It can be a powdered nasal cartilage product.

  Further, if necessary, the above powder is dissolved in water and heated to form a gel solution, and a re-lyophilization step in which the solution obtained in the dissolution step is freeze-dried by freeze drying. It has a configuration with. Since it is a gel-like solution, the components can be well dispersed and homogenized. If necessary, a gel-like solution can be distributed as a nasal cartilage product. Further, since the gel-like solution is freeze-dried in the re-lyophilization step, the freeze-dried mass can be distributed as a nasal cartilage product. In this case, since the gel-like solution is freeze-dried, the components can be well dispersed and uniformized.

  Furthermore, it is set as the structure provided with the re-grinding process which makes a dry substance powder with a particle size of 1 mm or less after the said re-freezing drying process. It can be a powdered nasal cartilage product. In this case, since the lump obtained by freeze-drying the gel-like solution is pulverized, it is possible to obtain a powder in which the components are well dispersed and homogenized.

  According to the present invention, since the posterior side of the nasal cartilage extracted from the fish head is dried, the amount of lipid in the posterior side of the nasal cartilage is small, so that a nasal cartilage product with very little lipid can be obtained. In other words, it is possible to produce fish nasal cartilage products by extracting only the posterior side of the nasal cartilage and not containing a considerable amount of lipid, and the conventional complicated processing after extraction can be omitted as in the past. , Manufacturing efficiency can be improved. The nasal cartilage product is not zero in lipids, but can be used for various foods as it is. Of course, as in the prior art, a purification treatment may be carried out so as to make the lipid substantially zero by performing a dissolution treatment with ethanol.

Hereinafter, based on an accompanying drawing, the manufacturing method of the nasal cartilage product of fish concerning an embodiment of the invention is explained in detail.
The method for producing a nasal cartilage product for fish according to an embodiment produces a nasal cartilage product obtained by drying nasal cartilage B in a fish head H of a salmon as a fish, as shown in FIGS. Is. The fish head H of the salmon is produced in large quantities as a by-product in the processing of the salmon, and has a nasal cartilage B at the upper part in the fish head H. Normal bones F are connected to the nasal cartilage B, and these are surrounded by a meat part M including the brain.

  As shown in FIGS. 4 and 5, the nasal cartilage product according to the embodiment includes nasal cartilage products (A) and (D) which are dry solids, and nasal cartilage products (B) and (E) which are dry powders. There is a nasal cartilage product (C) which is a gel solution.

First, a method for manufacturing a nasal cartilage product according to an embodiment for manufacturing nasal cartilage products (A) and (B) will be described. Since the nasal cartilage product (A) is obtained in the course of manufacturing the nasal cartilage product (B), the manufacturing method for manufacturing the nasal cartilage product (A) is shown in the manufacturing method for manufacturing the nasal cartilage product (B). As shown in FIGS. 1 to 4, this manufacturing method includes a rear posterior portion including the front end position Ia (P) of the eye of the nasal cartilage B from the fish head H in the front-rear direction R of the fish head H. A nasal cartilage product is produced by separating and extracting Br from the front side Bf and drying the rear side Br.

More specifically, the posterior side portion Br of the nasal cartilage B includes a lower interstitial cartilage Br1 positioned below the both eyes and an upper cartilage Bru provided so as to cover both eyes and the brain. Is done. Upper cartilage Bru includes a cap-like cartilage Brc lid-shaped upper side of the pituitary N, an upper precartilage Br2 in front of the cap-like cartilage Brc, on both side of the cap-like cartilage Brc and anterior superior cartilage Br2 A pair of upper transverse cartilage Br3 and Br4 and an upper posterior cartilage Br5 on the rear side of the lid cartilage Brc are configured.

  Then, this nasal cartilage product manufacturing method extracts the lower cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5 from the posterior side Br. The inferior cartilage Br1, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4 and superior posterior cartilage Br5 are dried to produce a nasal cartilage product. As shown in FIG. ), Extraction step (S12), freeze-drying step (S13), and crushing step (S14). The extraction step (S12) includes a preprocessing step (S12-1), a main processing step (S12-2), and a finishing step (S12-3). Hereinafter, each step will be described in detail.

(S11) Dividing Step As shown in FIGS. 1A, 1B, and 4, the fish head H is divided into an upper fish head Ha containing the nasal cartilage B and a lower fish head Hb not containing the nasal cartilage B. At the same time, the upper part Ha of the fish head is divided into an upper front part Hf including the front part Bf of the nasal cartilage B and an upper rear part Hr including the rear part Br of the nasal cartilage B. Thereby, the front side part Bf of the nasal cartilage B and the rear side part Br of the nasal cartilage B are divided. That is, after extracting all of the nasal cartilage B from the fish head H, this nasal cartilage B is not divided into the front part Bf and the rear part Br, but by dividing the fish head H itself, Is divided into a front side part Bf and a rear side part Br. The rear upper portion Hr of the fish head may be transferred to the next step as it is, but when stored, it may be frozen and stored frozen.

(S12) Extraction process Generally speaking, this extraction process is performed by putting the upper rear part Hr of the fish head divided in the fragmentation process shown in FIG. 1 (b) into water of less than 100 ° C., and removing the fleshy part M and the normal bone F. The lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4, and the superior posterior cartilage Br5 are extracted from the posterior side Br of the nasal cartilage B shown in FIG. In this case, in the above dividing step, the entire nasal cartilage B is extracted from the fish head H, and then the nasal cartilage B is not divided into the front side portion Bf and the rear side portion Br. Since the nasal cartilage B is divided into the front side part Bf and the rear side part Br by dividing the nasal cartilage B, when extracting the rear side part Br of the nasal cartilage B, the fleshy part M and the normal bone F are removed from the entire fish head H. Even if it does not, it is only necessary to remove the fleshy part M and the normal bone F from the upper rear part Hr of the fish head smaller than the whole fish head H obtained by dividing the fish head H. Therefore, the processing efficiency can be greatly improved.

In addition, in the extraction process, the fish head upper rear part Hr is put into water below 100 ° C., and the extra part including the fleshy part M and the normal bone F is removed, so that the extra part is exposed to water and removed. In addition, since the lipid dissolves into water, the lower cartilage Br1, the lower anterior cartilage Br2, the superior anterior cartilage Br2, the pair of the superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5. Can be extracted. Furthermore, since the treatment is performed with water having a temperature of 100 ° C. or lower, degeneration of the nasal cartilage B is prevented.
In detail, it becomes the following process order.

(S12-1) Pretreatment step As shown in FIGS. 1 (b), (c1), (c2), and FIG. 2 (a), the rear upper part Hr of the fish head is placed in water at 70 ° C. to 95 ° C. and stirred for the required time. Thus, an intermediate T including the posterior part Br of the nasal cartilage B from which the meat part M is removed as much as possible is obtained. Preferably, the temperature of water is 75 ° C to 90 ° C. For example, in the case where 300 Kg to 400 Kg of fish head upper rear portion Hr is processed at a time, as shown in FIG. 4, for example, water of 75 ° C. to 90 ° C. is put in a tank capable of storing 1 t of water, Add Hr above and below the fish head. The upper rear Hr of the fish head may be either raw or frozen. Warm the tank water to maintain the temperature. For example, the mixture is heated for 10 to 20 minutes and stirred. As a result, the meat part M is separated and becomes an intermediate T as shown in FIGS. 1 (c1) (c2) and 2 (a). The intermediate T is a state in which the normal bone F is connected to the posterior side Br of the nasal cartilage B, and the fleshy part M is also considerably adhered and remains. And this is taken out from a tank and what is called a kettle frying is performed. The extracted intermediate T is exposed to running water and cooled. The intermediate T in this state is about 200 kg.

  In this pretreatment step, the meat portion M is removed as much as possible from the rear upper portion Hr of the fish head, so that the handling of the intermediate T becomes easy thereafter, and the treatment can be facilitated. In this case, the posterior side portion Br of the nasal cartilage B is treated with a relatively high temperature hot water of 70 ° C. to 95 ° C., so that the meat part M is easily peeled off from the nasal cartilage B, and the processing efficiency is improved accordingly. . Moreover, in this temperature range, the number of general viable bacteria can be reduced.

(S12-2) Main Processing Step As shown in FIGS. 1 (c1) (c2) (d), 2 (a) (b), 3 (a) (b) (c), it is obtained in the preprocessing step. The obtained intermediate T is put into water at 25 ° C. to 50 ° C., and the excess portion including the meat part M and the normal bone F is removed from the intermediate T. Specifically, as shown in FIG. 4, the intermediate T is put in a net-like cocoon, and the cocoon is immersed in a container containing water at 25 ° C. to 50 ° C., and nasal cartilage is manually carried out in the cocoon. The rear side portion Br of B is extracted. The temperature of water is preferably 30 ° C to 40 ° C. Replace the water in the container multiple times. At the time of replacement, once the jar is raised from the water, the sewage in the container is discarded, fresh water is poured into the container, and the jar is immersed again in the container. For example, the container water is changed 5 to 6 times.

  Specifically, from the posterior side Br, the lid cartilage Brc is removed, and the lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4, and the superior posterior cartilage Br5 are extracted. In this case, in the posterior side of the nasal cartilage B, the lower interstitial cartilage Br1, the cricoid cartilage Brc, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4, and the superior posterior cartilage Br5 are connected to each other in a separable manner. Therefore, in this main processing step, when force is applied by pushing or pulling with a hand or the like, it is easily separated into individual lumps. Therefore, each part can be processed individually. In addition, the upper lid-like lid cartilage Brc can be easily removed. Since the lid-like cartilage Brc is a portion that is relatively hard and does not easily allow the lipid to flow out, by removing this, the lipid component of the nasal cartilage product can be reduced and the quality can be further improved. The lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5, which are taken out as they are or divided It is taken out by the lump.

  In this case, the meat T and the normal bone F are removed from the intermediate T by manually squeezing the intermediate T repeatedly and thoroughly. Since it is in a relatively warm water at 25 ° C to 50 ° C, it is easy to work by hand. The removed excess can be drained into the water through the eyelets. Further, if the bone attached to the nasal cartilage B is removed, it is discarded outside the heel. Since the water in the container is changed a plurality of times, the removal operation can be repeated until the water in the container is no longer dirty. In this case, it is possible to remove the extra part while confirming the extra part by touching with the hand, so that the extra part can be surely removed as compared with the mechanical processing, and the rear side Br of the pure nasal cartilage B can be removed. Lower interstitial cartilage Br1, superior anterior cartilage Br2, a pair of superior transverse cartilage Br3, Br4, superior posterior cartilage Br5 can be extracted. Also, since it is lukewarm water, lipids will dissolve in the water. At this time, the lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5 are traced by hand. Lipids can be easily dissolved into the lower nasal cartilage B with less lipid, and the superior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5 can be extracted.

  In general, when the nasal cartilage B is taken out, there is a large upper cartilage Bru of the nasal cartilage B provided so as to cover both eyes and the brain. Although the cartilage Br1 is discarded, the lower interstitial cartilage Br1 is also taken out in the present embodiment. Therefore, the recovery rate of nasal cartilage B is improved. The aggregate of the lower intercostal cartilage Br1, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4, and the superior posterior cartilage Br5 of the rear side portion Br of the extracted nasal cartilage B is about 100 kg.

(S12-3) Finishing step As shown in FIGS. 1 (d), (e), and FIG. 3 (c), the lower intercostal cartilage Br1, the superior anterior cartilage Br2, and the upper pair of the upper nasal cartilage B are extracted. The assembly of transverse cartilage Br3, Br4 and superior posterior cartilage Br5 is washed. The remaining excess part is surely removed. Try to reduce the surface somewhat. It becomes a rounded shape. Specifically, as shown in FIG. 4, the lower intercostal cartilage Br1, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4, and the superior posterior cartilage Br5 are gathered into a reticular cage as shown in FIG. And wash with running water by hand. The adhesion of impurities can be prevented. Thus, in the assembly of the lower cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4 and the superior posterior cartilage Br5 of the posterior side Br of the nasal cartilage B after the processing in the finishing step, 0.5 g / 100 g or less. Desirably, 0.4 g / 100 g or less, more desirably 0.3 g / 100 g or less. In this state, the assembly of the lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4, and the superior posterior cartilage Br5 is about 90 kg. The posterior side portion Br1 of the nasal cartilage B Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the posterior side portion of the superior posterior cartilage Br5 are respectively taken out as they are or divided. However, it may be taken out as it is or may be crushed into small pieces and transferred to the next step. In the case of storage, as shown in FIG. 4, for example, it may be frozen at −30 ° C. and stored frozen.

(S13) Freeze-drying step As shown in FIG. 4, the assembly of the lower intercostal cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5 is freeze-dried. Lyophilize with. In the case of an assembly of the lower cartilage Br1, the superior anterior cartilage Br2, the pair of superior transverse cartilage Br3, Br4, and the superior posterior cartilage Br5 of the posterior part Br of the raw nasal cartilage B, these are frozen. If frozen, thaw with steam and freeze again. Then, in a vacuum state with a well-known vacuum freeze-drying apparatus, the lower cartilage Br1, the lower anterior cartilage Br2, the superior anterior cartilage Br2, the pair of the superior transverse cartilage Br3, Br4 and the superior posterior cartilage Br5 in a vacuum state The water is sublimated and dried. When the lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5 in the rear side part Br of the nasal cartilage B are in the same mass or divided mass Is easy to handle during lyophilization. In this case, the posterior side portion Br of the nasal cartilage B has a water content of 85% by weight or more, and when lyophilized, it becomes a lump of porous brittle dry matter. This can be distributed as a nasal cartilage product (A).

(S14) Grinding step As shown in FIG. 4, the dried product is made into a powder having a particle size of 1 mm or less. It grind | pulverizes with a well-known grinder for foodstuffs, and it sifts with a sieve with an opening of 500 micrometers-1 mm, and obtains the powder of the particle size under a sieve. In the embodiment, a sieve having an aperture of 758 μm was used. This powder can be distributed as a nasal cartilage product (B). The lipid component corresponds to the lipid component in the lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5 after processing in the finishing process. 4.5 g / 100 g or less, desirably 3.6 g / 100 g or less, more desirably 2.7 g / 100 g or less.

  The nasal cartilage products (A) and (B) manufactured in this way are, as will be apparent from the analysis results described later, a lower intercostal cartilage Br1, a superior anterior cartilage Br2, a pair of nasal cartilage B Since the upper transverse cartilage Br3, Br4 and upper posterior cartilage Br5 have a small amount of lipid, they are extracted and dried, resulting in a nasal cartilage product with very little lipid. That is, the lower interstitial cartilage Br1, the superior anterior cartilage Br2, the pair of superior lateral cartilage Br3, Br4, and the superior posterior cartilage Br5 are extracted by extracting only the rear posterior part Br of the nasal cartilage B, so that a considerable amount of lipid is not contained. Nasal cartilage products can be manufactured, and since the complicated processing after extraction can be omitted as in the prior art, the manufacturing efficiency can be improved. The nasal cartilage product is not zero in lipids, but can be used for various foods as it is. In addition, when making lipid into zero or substantially zero, like the prior art, a dissolution process can be performed with ethanol.

  Next, a method for manufacturing a nasal cartilage product according to an embodiment for manufacturing nasal cartilage products (C), (D), and (E) will be described. Since the nasal cartilage products (C) and (D) are obtained during the production of the nasal cartilage product (E), the production method for producing the nasal cartilage products (C) and (D) is the nasal cartilage product (E). It shows in the manufacturing method which manufactures. This manufacturing method uses the powder of the nasal cartilage product (B) described above, and includes a dissolution step (S21), a re-lyophilization step (S22), and a re-pulverization step (S23) as shown in FIG. ing. Hereinafter, each step will be described in detail.

(S21) Dissolution Step As shown in FIG. 5, the powder is dissolved in water and heated to form a gel solution. For example, water in which powder is dissolved is placed in a pressure kettle and heated at 120 ° C. for 15 minutes. Thereby, a gel-like solution is obtained. Since it is a gel-like solution, the components can be well dispersed and homogenized. This gel solution can be distributed as a nasal cartilage product (C).

(S22) Re-lyophilization step As shown in FIG. 5, the solution obtained in the dissolution step is freeze-dried by freeze drying. First, the gel-like solution is frozen at −30 ° C., and reduced in pressure by a well-known vacuum freeze-drying apparatus to sublimate moisture from the frozen material and dry it. When lyophilized, it becomes a porous brittle dry mass. In this case, since the gel-like solution is freeze-dried, the components can be well dispersed and uniformized. This can be distributed as a nasal cartilage product (D).

(S23) Re-grinding step As shown in FIG. 5, the dried product is made into a powder having a particle size of 1 mm or less. It grind | pulverizes with a well-known grinder for foodstuffs, and it sifts with a sieve with an opening of 500 micrometers-1 mm, and obtains the powder of the particle size under a sieve. In the embodiment, a sieve having an aperture of 758 μm was used. In this case, since the lump obtained by freeze-drying the gel-like solution is pulverized, it is possible to obtain a powder in which the components are well dispersed and homogenized. This powder can be distributed as a nasal cartilage product (E).

  The nasal cartilage products (C), (D), and (E) manufactured in this way are also nasal cartilage products with very little lipid. Moreover, it becomes a uniform product in which the components are well dispersed.

<Test example>
Intermediate T (with normal bone F attached) obtained in the pretreatment step (S12-1) of the extraction step (S12), posterior side portion Br of the nasal cartilage B obtained in the finishing step (S12-3) About the powder (nasal cartilage product (B)) obtained in the assembly and crushing step (S14) of the inferior cartilage Br1, superior anterior cartilage Br2, pair of superior transverse cartilage Br3, Br4, superior posterior cartilage Br5 We commissioned the Japan Food Analysis Center to conduct a component analysis test. The results are shown in FIGS. From this result, the lipid component was 9.8 g / 100 g of intermediate T (FIG. 6), the lower cartilage Br1 of the posterior part Br1 of the nasal cartilage B1, the superior anterior cartilage Br2, the pair of upper lateral cartilage Br3, Br4, The aggregate of the superior posterior cartilage Br5 is 0.3 g / 100 g (FIG. 7), and the posterior part Br1 of the nasal cartilage B extracted in the extraction process, the superior cartilage Br2, the superior anterior cartilage Br2, and the pair of superior lateral cartilage Br3 It can be seen that Br4 and superior posterior cartilage Br5 have obviously less lipids. In addition, the lipid component of the powder (nasal cartilage product (B)) is 2.7 g / 100 g (FIG. 8), which is not as high as that of the powder that has been zeroed by the conventional ethanol treatment, but very little. It can be seen that this can be used for various foods.

  Moreover, about the powder obtained at the grinding | pulverization process (S14), it asked the general incorporated foundation Japan Food Research Center, and it measured also about the amount of mucopolysaccharide. As shown in FIG. 9, the amount is as large as 44.2 g / 100 g. From this point, it was found that the desired function can be exhibited and used for various foods.
