Description

本発明は、原料にサケ・マス類の頭部全体を用いコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体を製造する方法に関するものである。本発明により製造されるコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体は、健康食品のほか医薬品原料および化粧品原料として広く利用することができる。   The present invention relates to a method for producing a mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid using the entire head of salmon and trout as a raw material. The mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid produced according to the present invention can be widely used as a raw material for pharmaceuticals and cosmetics in addition to health foods.

工業的に生産されているコンドロイチン硫酸を含有するムコ多糖タンパク複合体は、原料に牛軟骨やサメ軟骨が用いられている。このうち、牛軟骨は狂牛病の危険性など原料の安全性に問題があり、サメ軟骨は資源保護の問題から漁獲量が制限を受ける傾向にあり、いずれも安定した原料を確保することが困難な状況にある。これらに代わる新たな原料として安定して大量に生産されるサケの鼻軟骨が使われ始めている。   An industrially produced mucopolysaccharide protein complex containing chondroitin sulfate uses bovine cartilage and shark cartilage as raw materials. Of these, bovine cartilage has problems with the safety of raw materials, such as the risk of mad cow disease, and shark cartilage tends to be limited in catch due to resource conservation problems. It is a difficult situation. Salmon nasal cartilage, which is stably produced in large quantities, is beginning to be used as a new raw material to replace them.

サケの鼻軟骨を原料としたコンドロイチン硫酸の製造に関しては、頭部より鼻軟骨を分離する方法として、加熱し網で分離する方法が開示され(特許第3385398号;特許文献1)、鼻軟骨からの抽出、精製に関しては限外ろ過により分離精製する方法(特許第3278629号;特許文献2)が提案されている。しかし、鼻軟骨は加工処理により排出される頭部の約10%であり、これらの方法で分離抽出を行う場合は、残りの90%は廃棄処理されているのが現状である。すなわち、北海道全体で漁獲されるサケ約15万トンに換算すると、頭部歩留まりが約10%なので、約1万3千5百トンが廃棄されることになる。   Regarding the production of chondroitin sulfate using salmon nasal cartilage as a raw material, as a method of separating nasal cartilage from the head, a method of heating and separating with a net is disclosed (Patent No. 3385398; Patent Document 1). Regarding the extraction and purification of the above, a method of separation and purification by ultrafiltration (Patent No. 3278629; Patent Document 2) has been proposed. However, nasal cartilage is about 10% of the head discharged by processing, and when performing separation and extraction by these methods, the remaining 90% is currently disposed of. That is, when converted to about 150,000 tons of salmon caught in Hokkaido as a whole, the head yield is about 10%, so about 13,500 tons are discarded.

特許第3385398号公報Japanese Patent No. 3385398 特許第3278629号公報Japanese Patent No. 3278629

このように、従来法は、頭部から鼻軟骨を分離して使用しているが、本発明者らは、鼻軟骨を分離後、廃棄されている90%の部分にも鼻軟骨と同等量のコンドロイチン硫酸と、コンドロイチン硫酸含有量の約1/20量のヒアルロン酸が含まれていることを見出した。
ヒアルロン酸に関しては、鼻軟骨中の含有量は極めて少ないものの、頭全体を利用することにより眼や頭皮などから効率よく回収することができた。鼻軟骨を分離しコンドロイチン硫酸を精製した場合、頭部全体から計算される歩留まりは0.2%であるが、頭全体より得られるコンドロイチン硫酸歩留まりは0.4%(そのうち5%がヒアルロン酸)となり、従来法の2倍量となる。しかし、頭部全体を原料とする場合には、硬骨などの不溶部位が多い、油分が多い、コンドロイチン硫酸濃度が低いなど種々の問題点がある。
従って、本発明の課題は、鼻軟骨以外廃棄されていた部位も含むサケ頭部全体を原料としてコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体を製造する技術を確立することにある。
As described above, the conventional method uses the nasal cartilage separated from the head. However, the present inventors have separated the nasal cartilage and then disposed of 90% of the discarded part in the same amount as the nasal cartilage. Of chondroitin sulfate and about 1/20 of the amount of chondroitin sulfate contained.
As for hyaluronic acid, although the content in nasal cartilage is extremely small, it was efficiently recovered from the eyes and scalp by using the entire head. When nasal cartilage is isolated and chondroitin sulfate is purified, the yield calculated from the entire head is 0.2%, but the chondroitin sulfate yield obtained from the entire head is 0.4% (of which 5% is hyaluronic acid). 2 times the amount. However, when the entire head is used as a raw material, there are various problems such as many insoluble sites such as bones, a large amount of oil, and a low chondroitin sulfate concentration.
Accordingly, an object of the present invention is to establish a technique for producing a mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid using as a raw material the entire salmon head including the discarded part other than nasal cartilage.

本発明者らは、上記課題に鑑みて鋭意検討した結果、サケ頭部全体を粉砕し、プロテアーゼ処理により可溶化し、得られた可溶化液から固体を分離した後、脱脂し、水相部位をフィルタープレスで清澄ろ過し、ろ液をさらに減圧濃縮後、必要に応じて活性炭処理し、噴霧乾燥することによって目的とするコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体を、コンドロイチン硫酸量として従来法の2倍量得ることができることを見出した。
また、この方法で、フィルタープレスにより得られた清澄ろ過液を膜分離により精製・濃縮することにより、任意の濃度のコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体を製造することもできる。
As a result of intensive studies in view of the above problems, the present inventors crushed the whole salmon head, solubilized by protease treatment, separated the solid from the obtained solubilized liquid, degreased, and the aqueous phase site The filtrate is concentrated under reduced pressure, the filtrate is further concentrated under reduced pressure, treated with activated carbon as necessary, and spray-dried to obtain the desired chondroitin sulfate and hyaluronic acid-containing mucopolysaccharide protein complex. As a result, it was found that a double amount of the conventional method can be obtained.
In addition, a mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid of any concentration can be produced by purifying and concentrating the clarified filtrate obtained by the filter press by membrane separation by this method.

That is, the present invention is 1. After crushing salmon and trout heads, solubilizing by protease treatment, separating and degreasing solids, drying the resulting aqueous phase and pulverizing, chondroitin sulfate and hyaluronic acid A method for producing a mucopolysaccharide protein complex composition.

A method for producing a mucopolysaccharide protein complex composition containing chondroitin sulfate and hyaluronic acid, which is characterized by being purified by the method described above, dried and powdered, and 3. A mucopolysaccharide protein complex composition containing chondroitin sulfate and hyaluronic acid or a mucopolysaccharide protein complex composition containing a chondroitin sulfate and hyaluronic acid salt obtained by the method of the preceding item 1 is used as an aqueous solution, and membrane separation is performed. The present invention relates to a method for producing a mucopolysaccharide protein complex composition containing chondroitin sulfate and hyaluronic acid at a high concentration, which is characterized by being dried and powdered after purification.

本発明では加工の残滓として排出されるサケ・マス類の頭部全体を原料として使用する。サケ・マス類の種類は、特に限定されないが、シロザケ、カラフトマス、ベニザケが挙げられる。特にシロザケが好ましい。
サケ頭部の可溶化は、サケ・マス類の頭部を適宜の大きさに切断した後、ミートチョッパー等の粉砕機で粉砕し、ミンチ状にした後、プロテアーゼ処理あるいはアルカリ処理により行うことができるが、プロテアーゼ処理が好ましい。
In the present invention, the entire head of salmon and trout discharged as processing residue is used as a raw material. The type of salmon and trout is not particularly limited, but may include chum salmon, calaf trout, and sockeye salmon. Especially chum salmon is preferable.
The salmon head is solubilized by cutting the salmon and trout heads to an appropriate size, crushing them with a crusher such as a meat chopper, making them mince, and then subjecting them to protease treatment or alkali treatment. Protease treatment is preferred.

プロテアーゼ処理に用いるプロテアーゼとしては市販品のいずれも使用できるが、膜分離によるコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体の精製・濃縮を効率よく行うには、タンパク分解能力の高い酵素の使用が望ましい。例えば、パパイン製剤やノボザイムズジャパン株式会社のアルカラーゼなどが用いられる。   Any commercially available protease can be used as a protease treatment, but in order to efficiently purify and concentrate mucopolysaccharide protein complexes containing chondroitin sulfate and hyaluronic acid by membrane separation, an enzyme with high proteolytic ability must be used. Use is desirable. For example, papain preparations or alcalase from Novozymes Japan Ltd. are used.

プロテアーゼによる可溶化液には、多量の脂質が含まれているのでこれを除くために三相分離を行って、油相、水相、固形相に分け、コンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体を含む水相を得る。さらにこの水相に珪藻土、バーライト、セルロース等から選択されるろ過助剤を加えてフィルタープレスにより清澄ろ過し、ろ液を得る。   Since the solubilized solution by protease contains a large amount of lipid, three-phase separation is performed to remove this, and it is divided into an oil phase, an aqueous phase and a solid phase, and mucopolysaccharide containing chondroitin sulfate and hyaluronic acid. An aqueous phase containing the protein complex is obtained. Further, a filter aid selected from diatomaceous earth, barlite, cellulose and the like is added to this aqueous phase, and the solution is clarified by a filter press to obtain a filtrate.

得られた水相を加熱蒸発法、減圧乾燥法、噴霧乾燥法、凍結乾燥法、あるいはこれらの方法を組み合わせて、乾燥し、粉末化することによりコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体組成物を得ることができる。この方法で得られる複合体組成物はコンドロイチン硫酸4.0%、ヒアルロン酸0.2%を含んでいるが、その他の主な成分としては、タンパク質88.3%、灰分6.5%を含む。この粗製品は、そのまま健康食品原料等として用いることができるが、さらに水溶液とした後膜分離法等により精製することもできる。   Mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid by drying and pulverizing the obtained aqueous phase by heating evaporation method, vacuum drying method, spray drying method, freeze drying method, or a combination of these methods A body composition can be obtained. The complex composition obtained by this method contains chondroitin sulfate 4.0% and hyaluronic acid 0.2%, but the other main components include protein 83.3% and ash content 6.5%. This crude product can be used as a raw material for health foods as it is, but it can be further purified by a membrane separation method after making it into an aqueous solution.

本発明では、前記粗製品からあるいは前記粗製品を得る前の三相分離により得たろ液を膜分離法により、高濃度にコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖を含む高濃度のタンパク複合体を得ることができるが、三相分離により得たろ液をそのまま膜分離する精製法が好ましい。   In the present invention, a high-concentration protein complex containing a mucopolysaccharide containing chondroitin sulfate and hyaluronic acid at a high concentration is obtained by membrane separation of the filtrate obtained from the crude product or by three-phase separation before obtaining the crude product. However, a purification method in which the filtrate obtained by three-phase separation is directly subjected to membrane separation is preferable.

すなわち、前記方法で三相分離により得たろ液には、コンドロイチン硫酸およびヒアルロン酸以外にも、タンパク質、アミノ酸、無機成分などが多く含まれており、コンドロイチン硫酸およびヒアルロン酸の割合が低いので限外ろ過膜により精製・濃縮処理を行う。使用する限外ろ過膜の分画分子量は5千〜10万、より望ましくは1万〜5万である。精製・濃縮処理は、ろ液に水を適宜加えて希釈し、限外ろ過によりコンドロイチン硫酸およびヒアルロン酸を含むムコ多糖タンパク複合体を精製・濃縮する工程を、任意の回数繰り返すことにより行う。この濃縮回数の違いにより、任意の濃度のコンドロイチン硫酸およびヒアルロン酸を含む精製液を得ることができる。精製液は、減圧濃縮後必要に応じて活性炭を使用し脱色、脱脂を行い、噴霧乾燥法等により乾燥して粉末とする。
精製品は、分離条件を変えることによって任意の濃度(例えば、約10〜70%)のコンドロイチン硫酸およびヒアルロン酸を含む組成物として得ることができる。
That is, the filtrate obtained by the three-phase separation by the above method contains many proteins, amino acids, inorganic components, etc. in addition to chondroitin sulfate and hyaluronic acid, and the ratio of chondroitin sulfate and hyaluronic acid is low. Purification and concentration are performed with a filtration membrane. The molecular weight cut off of the ultrafiltration membrane to be used is 5,000 to 100,000, more preferably 10,000 to 50,000. The purification / concentration treatment is performed by repeating the process of adding and appropriately diluting water to the filtrate and purifying / concentrating the mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid by ultrafiltration any number of times. A purified solution containing chondroitin sulfate and hyaluronic acid at any concentration can be obtained due to the difference in the number of times of concentration. The purified solution is concentrated under reduced pressure, decolorized and degreased using activated carbon as necessary, and dried by spray drying or the like to obtain a powder.
The purified product can be obtained as a composition containing chondroitin sulfate and hyaluronic acid at any concentration (for example, about 10 to 70%) by changing the separation conditions.

以上の本発明の方法により、サケ・マス類の頭部全体を主とする加工残滓から効率よく任意の濃度のコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体を製造することができる。   By the above-described method of the present invention, a mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid at any concentration can be efficiently produced from processing residues mainly of the salmon and trout heads.

以下、実施例により本発明を具体的に説明する。   Hereinafter, the present invention will be described specifically by way of examples.

実施例1:
(1)プロテアーゼ処理
1)加工残滓として排出されたサケ頭部40kgをバンドソーで約5mm角に切断後、穴径9.6mmのミートチョッパで粉砕し原料とした。

Example 1:
(1) Protease treatment 1) 40 kg of salmon head discharged as a processing residue was cut into about 5 mm square with a band saw and pulverized with a meat chopper having a hole diameter of 9.6 mm to obtain a raw material.
2) This was put into a 50 L oblique axis kneader, and after adding 80 g of protease (alcalase), the mixture was stirred at 50 ° C. for 2 hours to obtain a solubilized solution.
3) The obtained solubilized solution was filtered through a colander having an opening diameter of about 1 mm, and the residue remaining on the colander was washed with 8 kg of water.
4) The filtrate and the washing solution were returned to the oblique axis kneader, heated to 90 ° C., and stirred for 15 minutes for protease inactivation treatment. As a result, 49.4 kg of a solubilized solution was obtained.
5) The obtained solubilized solution was processed with a three-phase centrifuge having a centrifugal effect of 10,000 G, and separated into an oil phase, an aqueous phase, and a sludge phase. At this time, 3 kg of water was used as a cleaning liquid. By these operations, 39.0 kg of the degreased and desludged aqueous phase was collected.
6) 1.6 kg of a filter aid (diatomaceous earth) was added to the obtained aqueous phase and stirred, followed by pressure filtration at a pressure of about 4 kg / cm 2 . Further, after the cake was washed with 6 kg of water, the filtrate and the washing liquid were combined to obtain 39.1 kg of a clarified liquid. The Brix of this clarified liquid was 11.3.

(2)精製及び粉末化処理
1)得られた清澄液を分画分子量13,000の限外濾過膜(旭化成(株)製ACP−2013)により精製処理を行った。精製処理は、清澄液にその2倍量の水を加え、加える前の量まで濃縮する操作を5回繰り返した。これにより、Brix 0.9の精製液37.0kgが得られた。
2)この精製液を蒸発温度22〜24℃、ジャケット温度80℃において減圧濃縮し、Brix 11.1の濃縮液2.5kgを得た。
3)濃縮液にろ過助剤(珪藻土)0.1kgを加え撹拌後、圧力1.5kg/cm2において加圧ろ過を行った。さらに、ケーキを0.3kgの水で洗浄後、ろ液及び洗浄液を合わせ2.26kgの清澄液が得られた。
4)この清澄液をφ70mm回転ディスク型スプレードライヤーを用い、入口温度175℃、出口温度90℃、ディスク回転数18,000rpmの条件下で噴霧乾燥を行い、コンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体の白色粉末208gを得た。
(2) Purification and pulverization treatment 1) The resulting clarified liquid was purified by an ultrafiltration membrane (ACP-2013 manufactured by Asahi Kasei Co., Ltd.) having a molecular weight cut off of 13,000. In the purification treatment, the operation of adding twice the amount of water to the clarified liquid and concentrating to the amount before the addition was repeated 5 times. As a result, 37.0 kg of a purified solution of Brix 0.9 was obtained.
2) The purified solution was concentrated under reduced pressure at an evaporation temperature of 22-24 ° C. and a jacket temperature of 80 ° C. to obtain 2.5 kg of Brix 11.1 concentrate.
3) 0.1 kg of a filter aid (diatomaceous earth) was added to the concentrated solution and stirred, followed by pressure filtration at a pressure of 1.5 kg / cm 2 . Further, the cake was washed with 0.3 kg of water, and the filtrate and the washing solution were combined to obtain 2.26 kg of a clear solution.
4) The clarified liquid is spray-dried under conditions of an inlet temperature of 175 ° C., an outlet temperature of 90 ° C., and a disk rotational speed of 18,000 rpm using a φ70 mm rotating disk spray dryer, and a mucopolysaccharide protein containing chondroitin sulfate and hyaluronic acid. 208 g of white powder of the composite was obtained.

実施例1での各工程後(三相分離後、フィルタープレス後、膜処理5回後、減圧濃縮後及び噴霧乾燥後)について、サンプルを採り分析した結果に基づく製造歩留まりの変化と粉末のコンドロイチン硫酸含有量、ヒアルロン酸含有量とタンパク質含有量を表1および表2に示す。なお、コンドロイチン硫酸の分析は、ガランボス法(Galambos JT 1967 The reaction of carbazole with carbohydrates 1. Effect of borate and sulfamate on the carbazole color of sugars. Anal.Biochem. 19:119-132)によりグルクロン酸量を測定し、係数2.593を乗じてコンドロイチン硫酸量を求めた。ヒアルロン酸の分析は、電気泳動法(日本生化学会編.糖質II.29-31.1991)により分離したヒアルロン酸のスポットをデンシトメーターにより定量化し濃度を求めた。タンパク質はケルダール法により窒素を測定し、窒素含有量に係数5.56を乗じて求めた。   After each step in Example 1 (after three-phase separation, after filter press, after 5 membrane treatments, after vacuum concentration and after spray drying), changes in production yield and powdered chondroitin based on the results of analysis of samples taken The sulfuric acid content, hyaluronic acid content and protein content are shown in Tables 1 and 2. For chondroitin sulfate analysis, the amount of glucuronic acid was measured by the Galambos method (Galambos JT 1967 The reaction of carbazole with carbohydrates 1. Effect of borate and sulfamate on the carbazole color of sugars. Anal. Biochem. 19: 119-132). Then, the amount of chondroitin sulfate was obtained by multiplying the coefficient 2.593. For the analysis of hyaluronic acid, the spot of hyaluronic acid separated by electrophoresis (Japan Biochemical Society, edited by Carbohydrate II. 29-31.1991) was quantified with a densitometer to determine the concentration. Protein was determined by measuring nitrogen by the Kjeldahl method and multiplying the nitrogen content by a factor of 5.56.

なお、工程ごとの歩留まりの変化におけるコンドロイチン硫酸量は、グルクロン酸量をすべてコンドロイチン硫酸量に換算して求めたので、ヒアルロン酸も含む値である。粉末のコンドロイチン硫酸量は、グルクロン酸量から換算したコンドロイチン硫酸量から、別に電気泳動法により測定したヒアルロン酸量を差し引いて求めた値である。これらは以下の実施例2〜4でも同様である。   In addition, since the chondroitin sulfate amount in the change in yield for each process was determined by converting all the glucuronic acid amounts into chondroitin sulfate amounts, it is a value including hyaluronic acid. The amount of chondroitin sulfate in the powder is a value obtained by subtracting the amount of hyaluronic acid separately measured by electrophoresis from the amount of chondroitin sulfate converted from the amount of glucuronic acid. The same applies to Examples 2 to 4 below.

4)この清澄液を実施例1と同様に噴霧乾燥させ、コンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体の白色粉末184gを得た。実施例2での各工程後の製造歩留まりの変化と粉末のコンドロイチン硫酸含有量、ヒアルロン酸含有量とタンパク質含有量を表3および表4に示す。なお、分析方法は実施例1と同様である。

1) The number of purification treatments on the ultrafiltration membrane in Example 1 was set to 3, and the purified solution was concentrated under reduced pressure in the same manner as in Example 1 to obtain 3.2 kg of Brix 7.5 concentrate.
2) After adding 65 g of powdered activated carbon to this concentrate, the mixture was stirred at room temperature for 4 hours to perform activated carbon treatment.
3) 65 g of a filter aid was added to this treatment liquid and stirred, followed by suction filtration using a Nutsche pre-coated with a filter aid with a thickness of 2 mm. Further, the cake was washed with 0.5 kg of water, and then the filtrate and the washing solution were combined to obtain 3.5 kg of a clarified liquid.
4) This clarified liquid was spray-dried in the same manner as in Example 1 to obtain 184 g of a white powder of mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid. Table 3 and Table 4 show the change in production yield after each step in Example 2 and the chondroitin sulfate content, hyaluronic acid content and protein content of the powder.

実施例のまとめ:
実施例1〜4(表1〜8)より、サケ頭全体からのコンドロイチン硫酸およびヒアルロン酸の歩留まりは、膜処理後では当初の計算通り約0.4%となり、100kgの頭を処理すると400gのコンドロイチン硫酸およびヒアルロン酸を回収出来たが、実際にはその後の活性炭処理や噴霧乾燥処理により若干のロスが発生し、乾燥粉末品でのコンドロイチン硫酸およびヒアルロン酸の歩留まりは0.3%となった。つまり100kgの頭から300gのコンドロイチン硫酸およびヒアルロン酸を粉末化できたことになる。一方、頭100kgから鼻軟骨を分離しコンドロイチン硫酸を精製した場合、その含有率から求められる歩留まりは0.2%であり、得られる粉末は200gである。したがって本発明により得られるコンドロイチン硫酸およびヒアルロン酸は、従来法の1.5倍以上となる。これは北海道のサケ約15万トンの漁獲量に限って計算すると、従来法で30トン製造できるものが45トン以上に増加したことになる。ヒアルロン酸に関しては、鼻軟骨に含まれる濃度が0.01%未満と極めて少なく、従来法での製品中の含有量が明確ではなかったが、頭全体を原料としたことで、眼や頭皮などに含まれるヒアルロン酸が抽出できたものである。本発明により製造されるコンドロイチン硫酸およびヒアルロン酸を含有するムコ多糖タンパク複合体は、食品のほか医薬品原料および化粧品原料として広く利用することができるものであり、本発明の製造方法により安価に大量に供給できる。

Summary of examples:
From Examples 1 to 4 (Tables 1 to 8), the yield of chondroitin sulfate and hyaluronic acid from the whole salmon head was about 0.4% as originally calculated after membrane treatment, and 400 g of chondroitin sulfate after treating 100 kg of head. Although hyaluronic acid could be recovered, some loss was actually caused by the subsequent activated carbon treatment and spray drying treatment, and the yield of chondroitin sulfate and hyaluronic acid in the dry powder product was 0.3%. That is, 300 g of chondroitin sulfate and hyaluronic acid can be powdered from the head of 100 kg. On the other hand, when nasal cartilage is separated from 100 kg of the head and chondroitin sulfate is purified, the yield determined from the content is 0.2%, and the obtained powder is 200 g. Therefore, the chondroitin sulfate and hyaluronic acid obtained by the present invention are 1.5 times or more that of the conventional method. If this is calculated only for the catch of about 150,000 tons of salmon in Hokkaido, the amount that can be produced by 30 tons by the conventional method has increased to over 45 tons. Concerning hyaluronic acid, the concentration in nasal cartilage is extremely low, less than 0.01%, and the content in the product by the conventional method was not clear, but it was contained in the eyes and scalp etc. because the entire head was used as a raw material. Hyaluronic acid can be extracted. The mucopolysaccharide protein complex containing chondroitin sulfate and hyaluronic acid produced according to the present invention can be widely used as a raw material for pharmaceuticals and cosmetics in addition to foods. Can supply.
