Description

本発明は、魚介類の栄養補給剤の作製法に関するものである。   The present invention relates to a method for producing a nutritional supplement for seafood.

近年、日本の浜辺からアサリ・ハマグリ等の魚介類の収穫量が激減しているのは公知のことである。これは浜辺の表層より少し深い所にある還元層といわれる黒い土の部分に堆積している硫化水素に原因があると考えられている。硫化水素は酸性であり、本来魚介類の成育する還元層は弱アルカリ性（海水のPH値は７．８９）である。この変化によって日本の浜辺は、魚介類にとって栄養素となる微生物が生存できにくく、魚介類の成育自身が難しい環境になってきている。   In recent years, it has been well known that the yield of seafood such as clams and clams has been drastically reduced from the beaches in Japan. This is thought to be caused by hydrogen sulfide deposited on the black soil, which is said to be a reducing layer located slightly deeper than the surface of the beach. Hydrogen sulfide is acidic, and the reduced layer where seafood grows is weakly alkaline (PH value of seawater is 7.89). Due to this change, the beaches in Japan are becoming difficult to grow microorganisms, which are nutrients for seafood, and the growth of seafood itself is difficult.

魚介類の成育に欠かせない成分として、カルシウムやマグネシウムがある。これらの成分は、先に述べた還元層の変化によって、魚介類の成育場から失われてしまっている。その為、魚介類の成育の為には、これらの成分を人為的に供給する必要がある。その供給源として、化学的主成分の９０％以上が炭酸カルシウムである、カキ貝殻は最適である。既に、カキ貝殻には粉状に加工された物が、カキ貝殻粉として市販されており、酸性化された土壌の中和剤として利用されている。このことは、カキ貝殻粉が魚介類への栄養補給の役割だけでなく、成育場そのものの環境を整えるのにも適しているといえる。しかし、カキ貝殻粉を粉末のまま、浜辺に散布するのでは、魚介類の成育場となる還元層まで浸透しない為、カキ貝殻粉は塊状に固めた後供給する必要がある。更に、マグネシウムにおいては、粉状で市販されている水酸化マグネシウムを、先に述べたカキ貝殻粉を塊状にする際に併用すると有効である。   Ingredients essential for the growth of seafood include calcium and magnesium. These components have been lost from the seafood breeding ground due to the changes in the reducing layer described above. Therefore, it is necessary to artificially supply these ingredients for the growth of seafood. As its source, oyster shells, in which 90% or more of the chemical main component is calcium carbonate, are optimal. Already, oyster shells processed into powder are commercially available as oyster shell powder and are used as neutralizing agents for acidified soil. This can be said that oyster shell powder is suitable not only for the nutritional supply to seafood, but also for preparing the environment of the growth ground itself. However, if oyster shell powder is sprayed on the beach in the form of powder, it does not penetrate into the reducing layer that serves as a growth ground for seafood. Therefore, oyster shell powder needs to be supplied after it has been hardened into a lump. Further, in the case of magnesium, it is effective to use magnesium hydroxide, which is commercially available in powder form, when the oyster shell powder described above is made into a lump.

このことは、特許第３９９９５８５号で実施されている通りである。しかし、カキ貝殻粉と水酸化マグネシウムだけでは、塊状に固めることはできたが、これを海水に浸すとすぐに元の粉状にもどってしまう事が確認できた。特許第３９９９５８５号では、水酸化マグネシウムが、その接着力によってカキ貝殻粉を塊状に固めるバインダーとして、徐々に海水中に溶解し該塊状体の形状を小さくするか消失させる結合剤になっている、としていることから、一工夫加えられている可能性が考えられるが、その方法については定かではない。 This is as implemented in Japanese Patent No. 3999585. However, although oyster shell powder and magnesium hydroxide alone were able to harden into a lump, it was confirmed that they immediately returned to their original powder form when immersed in seawater. In Japanese Patent No. 3999585, magnesium hydroxide is a binder that hardens oyster shell powder into a lump by its adhesive force, and gradually dissolves in seawater to reduce or eliminate the shape of the lump. Therefore, there is a possibility that one device has been added, but the method is not certain.

前記背景技術で述べたように、近年の浜辺の還元層のヘドロ化により、浜辺の生態系が著しく悪化し、魚介類の成育が妨げられている。その為、魚介類への栄養補給には、生育場である浜辺の環境を取り戻すと共に、カルシウムやマグネシウム等の栄養素を人為的に供給する必要がある。その供給を、人の管理がなくても、半年以上にわたって維持、継続が可能な様に、塊状のものがゆっくりと海水に溶け出していく、魚介類への栄養補給剤の作製法を提供することを目的とする。   As described in the background art, due to the sludge formation of the reducing layer on the beach in recent years, the ecosystem on the beach has been remarkably deteriorated, and the growth of seafood has been hindered. For this reason, it is necessary to supply nutrients to seafood by artificially supplying nutrients such as calcium and magnesium, as well as restoring the environment of the beach where it grows. Providing a method for producing nutritional supplements for fish and shellfish in which lumps are slowly dissolved in seawater so that the supply can be maintained and continued for more than half a year without human management For the purpose.

本発明の第一発明は、魚介類への栄養補給剤の作製法として、カキ貝殻粉９０〜７０重量部、水酸化マグネシウム１０〜３０重量部の範囲で、合わせて１００重量部になる混合物に、水１０〜３０重量部を加えて練り、塊状に成型後、炭酸ガスによる化学反応にて硬化させることを最も主要な特徴とする。
また、本発明の第二発明は、魚介類への栄養補給剤の作製法として、カキ貝殻粉９０〜７０重量部、水酸化マグネシウム１０〜３０重量部の範囲で、合わせて１００重量部になる混合物に、セメント１０〜２０重量部、水１０〜２０重量部を加えて練り、塊状に成型後、乾燥させて固めるという、セメントを用いた物理的方法にて硬化させることを最も主要な特徴とする。
更に、本発明の第三発明は、魚介類への栄養補給剤の作製法として、カキ貝殻粉９０〜７０重量部、水酸化マグネシウム１０〜３０重量部の範囲で、合わせて１００重量部になる混合物に、水ガラス１０〜２０重量部、水１０〜２０重量部を加えて練り、塊状に成型後、乾燥させて固めるという、水ガラスを用いた物理的・化学的方法にて硬化させることを最も主要な特徴とする。水ガラスには、成型後であっても大気中の炭酸ガスを吸収することにより、化学反応にて成形品の硬化が進む特色がある。 The first invention of the present invention is a method for producing a nutritional supplement for fish and shellfish, in a mixture of 90 to 70 parts by weight of oyster shell powder and 10 to 30 parts by weight of magnesium hydroxide, and a total of 100 parts by weight. The main feature is that 10 to 30 parts by weight of water is added, kneaded, molded into a lump, and then cured by a chemical reaction with carbon dioxide gas.
In addition, the second invention of the present invention is a method for producing a nutritional supplement for fish and shellfish, in the range of 90 to 70 parts by weight of oyster shell powder and 10 to 30 parts by weight of magnesium hydroxide. The most important feature is that the mixture is kneaded by adding 10 to 20 parts by weight of cement and 10 to 20 parts by weight of water, molding into a lump shape, and then drying and solidifying by a physical method using cement. To do.
Furthermore, the third invention of the present invention is a method for producing a nutritional supplement for fish and shellfish, in the range of 90 to 70 parts by weight of oyster shell powder and 10 to 30 parts by weight of magnesium hydroxide, for a total of 100 parts by weight. Adding 10 to 20 parts by weight of water glass and 10 to 20 parts by weight of water to the mixture, kneading, forming into a lump, drying and solidifying, and curing by a physical and chemical method using water glass. The most important feature. Water glass has a feature that the molded product is cured by a chemical reaction by absorbing carbon dioxide in the atmosphere even after molding.

本発明の魚介類への栄養補給剤は、主に産業廃棄物として廃棄されているカキ貝殻を使用している。カキ貝殻の化学主成分は炭酸カルシウムであり、カキ貝殻の構成成分の９０％以上を占めている。この事により、貝類が大きく成長するのに欠かせないカルシウムを、大量になおかつ再利用する形で供給する事を可能とする。更に、炭酸カルシウムが海水に溶け出すことにより、酸性化した浜辺の還元層を本来の弱アルカリ性の状態に呈するという利点も併せ持っている。また助剤として使用する水酸化マグネシウムも魚介類の栄養素となり、海水に溶けると弱アルカリ性を呈する。   The nutritional supplement for fish and shellfish of the present invention uses oyster shells that are mainly discarded as industrial waste. The main chemical component of oyster shells is calcium carbonate, accounting for over 90% of the components of oyster shells. This makes it possible to supply a large amount of calcium, which is indispensable for shellfish growth, in a form that can be reused. Furthermore, when calcium carbonate dissolves into seawater, it also has the advantage of presenting the reduced layer on the acidified beach to its original weakly alkaline state. Magnesium hydroxide used as an auxiliary agent also serves as a nutrient for seafood, and exhibits weak alkalinity when dissolved in seawater.

しかし、これらの効果を持続させていくには、魚介類への栄養補給剤が徐々に海水に溶け出していく必要がある。その為本発明では、魚介類への栄養補給剤の作製法として、カキ貝殻粉と水酸化マグネシウムを塊状に成型後、第一発明では炭酸ガスによる化学反応、第二発明ではセメントを用いた物理的方法、第三発明では水ガラスを用いた物理的・化学的方法にて硬化させている。この事により、先の効果を半年以上、保持・継続することが出来る。 However, in order to maintain these effects, it is necessary for the nutritional supplements for seafood to gradually dissolve in seawater. Therefore, in the present invention, as a method for producing a nutritional supplement for fish and shellfish, after oyster shell powder and magnesium hydroxide are molded into a lump, the chemical reaction with carbon dioxide gas is used in the first invention, and the physical property using cement is used in the second invention. In the third method, curing is performed by a physical / chemical method using water glass. By this, the previous effect can be maintained and continued for more than half a year.

この実施形態によって本来粉状のカキ貝殻粉を水酸化マグネシウムと共に塊状に固め、その形状を海水に浸漬しても半年以上にわたって保持・継続し魚介類の栄養補給剤としての役割を提供するという目的を実現した。   The purpose of this embodiment is to provide a role as a nutritional supplement for fish and shellfish by consolidating the powdery oyster shell powder together with magnesium hydroxide into a lump and retaining and continuing the shape for more than half a year even when immersed in seawater Realized.

始めに、カキ貝殻粉１を９０〜７０重量部、水酸化マグネシウム２を１０〜３０重量部の範囲で、合わせて１００重量部になる割合で配合する。それに、水５を１０〜３０重量部加え、撹拌機６でよく練ってペースト状７にする。次に、直径１０ｍｍ奥行き１５ｍｍ程度の円筒状で圧力がかけられる器具Ｃに前記ペースト７を充たすまで入れ、それを万力Ｄを使って水分が出なくなるまで絞る。これによって直径が１０ｍｍ、長さが約１０ｍｍの円筒状の成型品Ｅを作る。この様な成型品Eを、同様の手順を繰り返すことにより複数個作り出す。（図１）   First, oyster shell powder 1 is blended in a proportion of 90 to 70 parts by weight and magnesium hydroxide 2 in the range of 10 to 30 parts by weight, for a total of 100 parts by weight. 10 to 30 parts by weight of water 5 is added to it, and kneaded well with a stirrer 6 to obtain a paste 7. Next, it puts in the cylinder C about 10 mm in diameter and 15 mm in depth which can apply pressure until it fills with the said paste 7, It is squeezed until a water | moisture content does not come out using a vise. Thus, a cylindrical molded product E having a diameter of 10 mm and a length of about 10 mm is produced. A plurality of such molded products E are produced by repeating the same procedure. (Figure 1)

カキ貝殻粉１と水酸化マグネシウム２の量の検討や、上記レシピを確定するのに先立ち、カキ貝殻粉１と水酸化マグネシウム２の適正な混合比の検討を行った。すなわち、カキ貝殻粉１の量を９５．９０．８０．７０．６０．５０．重量部に対し、水酸化マグネシウム２の量を５．１０．２０．３０．４０．５０重量部混ぜて検討した。この結果水酸化マグネシウム２の量が少なすぎても、多すぎても炭酸ガス８による化学反応が進みづらくなるためか、成型品Ｅの強度は下がってしまった。（図４のグラフ１）また、水酸化マグネシウム２が多くなるとコストが高くなるデメリットも出てくる。よって、カキ貝殻粉１と水酸化マグネシウム２の混合比は、カキ貝殻粉１が９０〜７０重量部、水酸化マグネシウム２が１０〜30重量部、更には８５〜７５重量部と１５〜２５重量部がベストであると思われる。 Prior to the examination of the amount of oyster shell powder 1 and magnesium hydroxide 2 and the determination of the above recipe, an appropriate mixing ratio of oyster shell powder 1 and magnesium hydroxide 2 was examined. That is, the amount of oyster shell powder 1 is 95.90.80.70.60.50. The amount of magnesium hydroxide 2 was studied by mixing 5.10.20.30.40.50 parts by weight with respect to parts by weight. As a result, even if the amount of magnesium hydroxide 2 is too small or too large, the chemical reaction by the carbon dioxide gas 8 is difficult to proceed. (Graph 1 in FIG. 4) Further, as the amount of magnesium hydroxide 2 increases, there is a disadvantage that the cost increases. Therefore, the mixing ratio of oyster shell powder 1 and magnesium hydroxide 2 is 90 to 70 parts by weight for oyster shell powder 1, 10 to 30 parts by weight for magnesium hydroxide 2, and 85 to 75 parts by weight and 15 to 25 parts by weight. The department seems to be the best.

そしてポリエチレン製等の密封性の高い袋状のもの９を用意し、その容量に対して３分の１程度に、前記成型品Ｅを入れる（図３のイ）。そこに炭酸ガス８を充分量吹き込み（図２）、密封した状態で一昼夜放置する（図３のロ）。成型品Ｅが３分の１程度なのは、炭酸ガス８の割合が少なすぎると、十分な化学反応が進まない為である。翌日には炭酸ガス８が成型品Eに吸収されて密封したものは真空に近い状態まで萎んでいる（図３のハ）。その後密封を解き、霧吹き等で水５を噴霧して再度成型品Eを充分に湿らす（図３のニ）。そして再び炭酸ガス８を充分量封入し、また一昼夜放置する（図３のホ・へ）。およそ同工程（図３のニ〜へ）を3〜5回繰り返す。１回目では海水に入れるとすぐ形の崩れていた成型品も、繰り返すうち、崩れることなく強固な成型品となる。（図３）   Then, a highly bag-like bag 9 made of polyethylene or the like is prepared, and the molded product E is put in about one third of the capacity (a in FIG. 3). A sufficient amount of carbon dioxide gas 8 is blown into the chamber (FIG. 2) and left in a sealed state for a whole day and night (b in FIG. 3). The reason why the molded product E is about one third is that when the proportion of the carbon dioxide gas 8 is too small, a sufficient chemical reaction does not proceed. On the next day, the carbon dioxide 8 absorbed by the molded product E and sealed is deflated to a state close to a vacuum (C in FIG. 3). Thereafter, the seal is released, and water 5 is sprayed with a spray or the like to sufficiently wet the molded product E again (d in FIG. 3). Then, a sufficient amount of carbon dioxide gas 8 is filled again and left for a whole day and night (e.g. in FIG. 3). About the same process (d in Fig. 3) is repeated 3 to 5 times. In the first round, a molded product that has collapsed as soon as it is put into seawater will become a strong molded product without collapsing over time. (Figure 3)

混合比の検討結果にもとずき、カキ貝殻粉１は80重量部、水酸化マグネシウム２は２０重量部と固定し、水５は10〜20重量部加え、ペースト状７から、成型品E作製までを行い、その後、炭酸ガス８の封入回数と固さとの関係を検討した。まず、試験片として用意した１０個づつの成型品Eを、海水を入れたビーカーの中に２４時間浸漬する。その後、取り出した試験片に、試験者が親指を使い上から体重をかけることによって、試験片がどの程度ばらけるかを観察した。（図４のグラフ２） 図４では、試験片１０個の内のばらけなかった個数（縦軸）を示している。この結果、炭酸ガス８の封入回数は３回以上行うことが望ましいといえる。   Based on the results of the mixing ratio study, oyster shell powder 1 was fixed at 80 parts by weight, magnesium hydroxide 2 was fixed at 20 parts by weight, water 5 was added at 10-20 parts by weight, and paste 7 was used to form molded product E. After the production, the relationship between the number of times carbon dioxide 8 was sealed and the hardness was examined. First, ten molded articles E prepared as test pieces are immersed in a beaker containing seawater for 24 hours. After that, the tester observed how much the test piece was scattered by putting the weight on the thumb using the thumb. (Graph 2 in FIG. 4) FIG. 4 shows the number (vertical axis) of the 10 test pieces that were not scattered. As a result, it can be said that it is desirable that the carbon dioxide gas 8 is sealed three times or more.

更に、炭酸ガス８の検討に先立ち、混練用の水５のかわりに市販されている炭酸水(サントリー製)を用いてみたが、成型品はすぐ崩れ、効果は低かった。また炭酸ガス８のかわりに、溶接で使われるアルゴン/炭酸ガスの混合ガスを用いてみた。しかし、十分な固さの成型品は得られなかった。これらの結果により、カキ貝殻粉１と水酸化マグネシウム２のバインダーとしてはピュアな炭酸ガスが最適であると確認できた。     Further, prior to the study of the carbon dioxide gas 8, a commercially available carbonated water (manufactured by Suntory) was used instead of the kneading water 5, but the molded product collapsed quickly and the effect was low. Also, instead of carbon dioxide 8, I tried using a mixed gas of argon / carbon dioxide used in welding. However, a molded product with sufficient hardness could not be obtained. From these results, it was confirmed that pure carbon dioxide was optimal as a binder for oyster shell powder 1 and magnesium hydroxide 2.

実施例２では、実施例１で成形品Eを硬化させるのに炭酸ガス８を用いたのに対して、バインダーとしてセメント３を用いて硬化させる。まず、カキ貝殻粉１を８０重量部と水酸化マグネシウム２を２０重量部、さらにセメント３を２０重量部それぞれ配合し、配合したものに水５を２０重量部加え、撹拌機６でよく練ってペースト状７にする。次に、直径１０ｍｍ奥行き１５ｍｍ程度の円筒状で圧力がかけられる器具Cに前記ペースト７を充たすまで入れ、それを万力Dを使って水分が出なくなるまで絞る。これによって直径が１０ｍｍ、長さが約１０ｍｍの円筒状の成型品Eを作る。この様な成型品Eを、同様の手順を繰り返すことにより複数個作り出す。（図１）そして室内に新聞紙等を敷きその上で成形品Eを自然乾燥させる。   In Example 2, carbon dioxide 8 was used to cure the molded product E in Example 1, whereas cement 3 was used as a binder. First, 80 parts by weight of oyster shell powder 1, 20 parts by weight of magnesium hydroxide 2 and 20 parts by weight of cement 3 were blended, 20 parts by weight of water 5 was added to the blended material, and kneaded well with a stirrer 6. Make paste 7 Next, the paste C is put in a cylinder C having a diameter of about 10 mm and a depth of about 15 mm, and the pressure is applied, and is squeezed using a vise D until no moisture is produced. Thus, a cylindrical molded product E having a diameter of 10 mm and a length of about 10 mm is produced. A plurality of such molded products E are produced by repeating the same procedure. (Fig. 1) And newspaper is laid in the room, and then the molded product E is naturally dried.

実施例１と同様の方法で固さを検討した結果、セメント３の量が１０重量部以上では、１０個共にばらけることなく、形は維持されていた。（図４のグラフ３）この結果、セメント３をバインダーとして用いる場合、セメント３の量は１０重量部以上必要である。また２０重量部でも硬さが変わらない点から、セメント３の量は１０〜２０重量部が望ましい。これより少ないと固化しづらく、多いのは無駄である。   As a result of examining the hardness in the same manner as in Example 1, when the amount of the cement 3 was 10 parts by weight or more, the ten pieces were not dispersed and the shape was maintained. (Graph 3 in FIG. 4) As a result, when cement 3 is used as a binder, the amount of cement 3 needs to be 10 parts by weight or more. Further, the amount of cement 3 is desirably 10 to 20 parts by weight because the hardness does not change even at 20 parts by weight. If it is less than this, it will be hard to solidify, and it will be useless.

実施例３では、実施例１で成形品Eを硬化させるのに炭酸ガス８を用いたのに対して、バインダーとして水ガラス４を用いて硬化させる。まず、カキ貝殻粉１を８０重量部と水酸化マグネシウム２を２０重量部、さらに水ガラス４を２０重量部それぞれ配合し、配合したものに水５を２０重量部加え、撹拌機６でよく練ってペースト状７にする。次に、直径１０ｍｍ奥行き１５ｍｍ程度の円筒状で圧力がかけられる器具Cに前記ペースト７を充たすまで入れ、それを万力Dを使って水分が出なくなるまで絞る。これによって直径が１０ｍｍ、長さが約１０ｍｍの円筒状の成型品Eを作る。この様な成型品Eを、同様の手順を繰り返すことにより複数個作り出す。（図１）そして室内に新聞紙等を敷きその上で成形品Eを自然乾燥させる。   In Example 3, carbon dioxide gas 8 was used to cure the molded product E in Example 1, whereas water glass 4 was used as a binder for curing. First, 80 parts by weight of oyster shell powder 1, 20 parts by weight of magnesium hydroxide 2 and 20 parts by weight of water glass 4 were blended, 20 parts by weight of water 5 was added to the blended material, and kneaded well with a stirrer 6. To paste 7 Next, the paste C is put in a cylinder C having a diameter of about 10 mm and a depth of about 15 mm, and the pressure is applied, and is squeezed using a vise D until no moisture is produced. Thus, a cylindrical molded product E having a diameter of 10 mm and a length of about 10 mm is produced. A plurality of such molded products E are produced by repeating the same procedure. (Fig. 1) And newspaper is laid in the room, and then the molded product E is naturally dried.

実施例１と同様の方法で固さを検討した結果、水ガラス４の量が１０重量部以上では、１０個共にばらけることなく、形は維持されていた。（図４のグラフ４）この結果、水ガラス４をバインダーとして用いる場合、水ガラス４の量は１０重量部以上必要である。また２０重量部でも硬さが変わらない点から、水ガラス４の量は１０〜２０重量部が望ましい。これより少ないと固化しづらく、多いのは無駄である。 As a result of examining the hardness by the same method as in Example 1, when the amount of the water glass 4 was 10 parts by weight or more, the shape was maintained without being dispersed. (Graph 4 in FIG. 4) As a result, when the water glass 4 is used as a binder, the amount of the water glass 4 needs to be 10 parts by weight or more. Further, the amount of water glass 4 is preferably 10 to 20 parts by weight because the hardness does not change even at 20 parts by weight. If it is less than this, it will be hard to solidify, and it will be useless.

「実施形態の効果」
実施例１、２、３、によって作製した試験片を各100ｇ定量し、１０００ｍｌのビーカーに入れる。これに海水を加え、内容量を１０００ｍｌとする。各試験片それぞれをモーター付撹拌機にて連続撹拌しながら、６ヶ月にわたり、一定期間毎に海水のＰＨを測定した。この結果２週間で最大値（ＰＨ９．２）に達し、その後は６ヶ月にわたって徐々に低下していった。６ヶ月後の平均ＰＨ値は８．５であり、海水のＰＨ値７．８９より高かった。このことは、カルシウムやマグネシウムが海水中に徐々に溶け出していることをうかがわせる実験結果であると思える。すなわち、魚介類の栄養補助剤として、また、還元層の中和の効果を保持・持続させるものと考えられる。尚、作製法の違いから、ＰＨ値は実施例１が実施例２、３に比べ約０．１低かった。 "Effect of the embodiment"
The test pieces prepared according to Examples 1, 2, and 3 are weighed in an amount of 100 g and placed in a 1000 ml beaker. Seawater is added to this to make the volume 1000 ml. While continuously stirring each test piece with a motor-equipped stirrer, the pH of seawater was measured at regular intervals over a period of 6 months. As a result, the maximum value (PH 9.2) was reached in 2 weeks, and then gradually decreased over 6 months. The average PH value after 6 months was 8.5, which was higher than the pH value of seawater 7.89. This seems to be an experimental result showing that calcium and magnesium are gradually dissolved in seawater. That is, it is considered that the effect of neutralizing the reducing layer is maintained and maintained as a nutritional supplement for fish and shellfish. The PH value of Example 1 was about 0.1 lower than that of Examples 2 and 3 due to the difference in production method.
