Description

【0001】
【発明の属する技術分野】
本発明は外観的に優れた化粧品、食品、装飾品等に用いることができる真珠層粉末に関する。
【0002】
【従来の技術】
本発明者らは特公平6−43320号公報、特願2001−153341号公報で示すようにアコヤ貝貝殻から真珠層を取り出す方法を見出した。従来、アコヤ貝貝殻は真珠養殖の副産物として多く発生している。その一部が粉砕されて家畜の飼料、あるいは食品に利用されているが、残りの大部分の貝殻は廃棄され海洋等の汚染を招いている。このアコヤ貝の貝殻利用方法を提示した。
また、特願2001−279412号公報で真珠光沢を活かした応用方法についても提示している。
【0003】
【発明が解決しようとする課題】
この結果、アコヤ貝貝殻の利用は進んだが一部に問題があり、さらに利用価値を見出し、現状でも廃棄されている貝殻の利用を高めていく必要がある。本発明者らは、上記のように真珠層を取り出すことに成功し、真珠層粉末である利点を最大限に活かす方法を検討した。このことは、アコヤ貝を有効利用することによって環境資源リサイクル或いはエコロジーの思想を重視することになり、地球環境の改善に役立つ。
【0004】
【課題を解決するための手段】
本発明者らは鋭意検討した結果、アコヤ貝の真珠層はコンキオリンという硬蛋白質が層状に存在し、非常に染色性がよいことがわかった。この染色性を利用すると、さらに真珠層粉末の利用範囲が拡大することがわかった。また、粉砕の程度によって真珠光沢を残したまま着色することも可能である。この場合、真珠光沢と染色の2つの特徴を持たせることができるため、さらに用途が拡がる。それにより廃棄されていたアコヤ貝の貝殻をより有効に利用できる。
【0005】
アコヤ貝から真珠層を得る方法は特に限定はないが、特公平6−43320号公報、特願2001−153341号公報記載の方法がよい。
まず、アコヤ貝貝殻を公知の回転式可傾型バレル研磨機と塩酸水溶液を用いて処理することとした。塩酸を用いたのはアコヤ貝貝殻の真珠層を除いた部分を崩壊もしくは溶解させる力が強く、また安価であるためである。塩酸の濃度は好ましくは5〜50%で、5%以上であれば操作時間等の操作方法によって、貝殻の稜柱層はほとんど除去されるが、50%を越えてもその効果に変化はなかった。また塩酸の量は処理するアコヤ貝貝殻の真珠層を除いた部分を溶解し得る量、すなわちアコヤ貝貝殻の真珠層を除いた部分にある炭酸カルシウムを塩化カルシウムに変えるのに必要な量を用いる。これは除去する部分のほとんどが炭酸カルシウムでありその除去に必要な塩酸が研磨液中に存在すればよいからである。
【0006】
またこの操作でアコヤ貝貝殻の真珠層を除いた部分の除去は塩酸によってのみ行われるのではなく、研磨機による物理的な方法でも行われるのである。これは、真珠層の炭酸カルシウムはアラレ石型結晶構造であるのに対して、除去の対象となる稜柱層のそれは方解石型結晶構造をとり、後者は含まれる蛋白の割合も高く、硬度が低く、塩酸や物理的な刺激によって真珠層よりも崩壊もしくは溶解しやすい性質がある。また塩酸の量が貝殻の真珠層以外の部分を除去するに必要な量より過剰になれば廃液を処理するための中和に費用がかかる。その結果、塩酸の必要量はその処理時間等の操作方法によって異なるがアコヤ貝貝殻の真珠層を除いた部分にある炭酸カルシウムを塩化カルシウムに変えるのに必要な量の0.5〜1.5倍が適切であることがわかった。さらに操作時間、回転数等の操作方法および貝殻、研磨液、研磨石の仕込み量や塩酸の濃度等を考慮して決める。また研磨石は酸化アルミニウムの材質のものを使用すればより効果的である。
【0007】
回転式可傾型バレル研磨機において上記の処理をする場合、塩酸と貝殻が反応するとき、泡が多量に発生し、開放状態で実施すれば、研磨機から研磨液や貝殻が溢れる。また密封状態で実施した後、処理物を取り出す際に、通常の方法で蓋を開放すると研磨機から内容物が飛び出し、収量にも影響し、また作業者にとっても非常に危険である。このため、本発明者らは以下の方法を採用することで問題を解決した。すなわち、回転式可傾型バレル研磨機の上部の蓋の部分に1ヶ所以上、好ましくは2ヶ所以上に内径0.5〜5cmのバルブを設ける。1ヶ所では、内容物が詰まる場合がある。処理後、暫く放置したのち、バルブを徐々に開放する。このようにすれば、回転式可傾型バレル研磨機を有効に利用でき、且つ作業も安全に実施できる。このように処理することにより貝殻の真珠層部分を得る。研磨処理ののち処理した貝殻と研磨石はそれらの大きさの差により篩などを利用して分別する。
【0008】
これらの工程によって得られる貝殻(主に真珠層)には若干稜柱層等が残っている。化粧品等に利用する場合、この稜柱層等が美的外観を損ねる場合があり、用途によっては以下の操作を実施した方が商品価値が高まり、本発明の主旨がより向上する。
その方法は貝殻(主に真珠層)を強アルカリの溶液に浸漬する。強アルカリは、特に限定はないが、食品や化粧品に利用するため、匂いなどが残らないものがよく、水酸化ナトリウムや水酸化カリウム等が適当である。濃度は、浸漬時間や稜柱層の残った程度、アルカリの種類によって異なるが、0.5〜15%がよく、浸漬時間も種々の条件によって異なるが、1時間から5日程度がよい。
浸漬後水洗する。しかしながら、よく水洗しても、アルカリが真珠層に残るので、用途によっては、薄い酸の水溶液に数十分から数時間浸漬して中和した方がよい場合がある。ここで用いる酸は塩酸や酢酸、クエン酸等を用いることが出来る。
【0009】
これにより得た貝殻を必要により水洗後乾燥し、粉砕する。粉砕は公知の方法、すなわち、カッターミル、アトマイザーあるいはジェットミルなどの装置を用いればよい。
粉砕は真珠光沢を有するようにする場合は、粉末の大きさは0.05〜2mm程度がよくこの大きさになるように粉砕する。しかしこの大きさのみ得ることは困難でありこの大きさの粉末が最大量になるように粉砕したのち、篩などで分別すればよい。これより大きな粉末は再度粉砕し、これより小さい粉末は真珠光沢を必要としない製品に利用すればよい。
真珠光沢を特に必要としない場合は、用途によって粉砕の程度を決定すればよい。
このようにして得たアコヤ貝真珠層粉末に対して必要により、エタノールを0.5〜2倍量加えてよく混合し、30分〜数日間浸漬処理したのち乾燥させる。
【0010】
このようにして得たアコヤ貝貝殻の真珠層粉末を染色する。染色の方法は特に限定はなく、一般的な方法をとればよい。一例を挙げれば、真珠層粉末を水或いは有機性親水溶媒、例えば、エタノール、メタノール、アセトン等、若しくは有機性親水溶媒と水と混合した溶媒に色素を用途や希望する染色強度、色素の種類によって異なるが、0.01〜1%の濃度で溶解し、30分間〜5日間放置する。なお、食品に応用する場合は有機性親水溶媒はエタノールが好ましい。また、染色に用いる色素も天然色素等安全性の高い物質を用いるのが好ましい。用いる色素を以下に例示するが当然これに限定されることはないが用途等によっては利用できる色素が限定される場合がある。

BACKGROUND OF THE INVENTION
The present invention relates to a pearl layer powder that can be used for cosmetics, foods, decorations, and the like that are excellent in appearance.
[0002]
[Prior art]
The present inventors have found a method for taking out a nacre from an pearl oyster shell as shown in Japanese Patent Publication No. 6-43320 and Japanese Patent Application No. 2001-153341. Traditionally, pearl oyster shells are often generated as a byproduct of pearl farming. A part of the shell is crushed and used for livestock feed or food, but most of the remaining shells are discarded to cause pollution of the ocean. A method for using the shell of this pearl oyster was presented.
Japanese Patent Application No. 2001-279212 also presents an application method utilizing pearl luster.
[0003]
[Problems to be solved by the invention]
As a result, the use of pearl oyster shells has progressed, but there are some problems, and it is necessary to find the value of use and increase the use of shells that are discarded even now. The present inventors have succeeded in taking out the nacreous layer as described above, and studied a method for making the most of the advantages of the nacreous layer powder. This means that the philosophy of environmental resource recycling or ecology is emphasized by effectively using pearl oysters, which helps to improve the global environment.
[0004]
[Means for Solving the Problems]
As a result of intensive studies, the present inventors have found that the pearl layer of pearl oysters has a hard protein called conchiolin in a layered form and has a very good dyeability. It has been found that the use range of the nacreous powder is further expanded by utilizing this dyeability. It is also possible to color with pearl luster remaining depending on the degree of grinding. In this case, since the two characteristics of pearl luster and dyeing can be provided, the use is further expanded. As a result, the oyster shells that have been discarded can be used more effectively.
[0005]
The method for obtaining the pearl layer from the pearl oyster is not particularly limited, but the methods described in Japanese Patent Publication No. 6-43320 and Japanese Patent Application No. 2001-153341 are preferable.
First, the pearl oyster shell was treated using a known rotary tilt barrel barrel machine and aqueous hydrochloric acid. Hydrochloric acid was used because it has a strong power to disintegrate or dissolve the portion of the pearl oyster shell except the pearl layer and is inexpensive. The concentration of hydrochloric acid is preferably 5 to 50%, and if it is 5% or more, the ridge pillar layer of the shell is almost removed by the operation method such as the operation time, but the effect is not changed even if it exceeds 50%. . The amount of hydrochloric acid is the amount that can dissolve the portion of the pearl oyster shell excluding the pearl layer to be treated, that is, the amount necessary to convert the calcium carbonate in the portion other than the pearl layer of the pearl oyster shell to calcium chloride. . This is because most of the part to be removed is calcium carbonate and the hydrochloric acid necessary for the removal should be present in the polishing liquid.
[0006]
In addition, the removal of the portion of the pearl oyster shell excluding the pearl layer by this operation is not only performed by hydrochloric acid but also by a physical method using a polishing machine. This is because the nacreous calcium carbonate has an aragonite-type crystal structure, whereas the ridge-pillar layer to be removed has a calcite-type crystal structure, and the latter has a high proportion of protein and low hardness. It is more easily disintegrated or dissolved than nacre by hydrochloric acid or physical stimulation. In addition, if the amount of hydrochloric acid exceeds the amount necessary for removing the portion other than the nacre of the shell, neutralization for treating the waste liquid is expensive. As a result, the required amount of hydrochloric acid varies depending on the operation method such as the treatment time, but 0.5 to 1.5 of the amount necessary to convert calcium carbonate in the portion excluding the pearl layer of the pearl oyster shell to calcium chloride. Double was found to be appropriate. Furthermore, it is determined in consideration of the operation method such as the operation time and the number of revolutions, the amount of shells, polishing liquid and polishing stones, and the concentration of hydrochloric acid. It is more effective to use a grinding stone made of aluminum oxide.
[0007]
When the above treatment is performed in a rotary tilt barrel polishing machine, a large amount of foam is generated when hydrochloric acid and the shell react, and if the polishing is carried out in an open state, the polishing liquid and the shell overflow from the polishing machine. Further, when the processed product is taken out after being carried out in a sealed state, if the lid is opened by a usual method, the contents will pop out from the polishing machine, which will affect the yield, and it is very dangerous for the operator. For this reason, the present inventors solved the problem by adopting the following method. That is, a valve having an inner diameter of 0.5 to 5 cm is provided at one or more, preferably two or more, in the upper lid portion of the rotary tilt barrel polishing machine. At one location, the contents may become clogged. After the treatment, leave it for a while and then gradually open the valve. In this way, the rotary tilting barrel grinder can be used effectively and the work can be performed safely. By processing in this way, the nacreous layer portion of the shell is obtained. After the polishing process, the processed shell and the polished stone are separated using a sieve or the like according to the difference in size.
[0008]
In the shells (mainly pearl layers) obtained by these processes, a ridge pillar layer or the like remains slightly. When used for cosmetics and the like, this ridged pillar layer or the like may impair the aesthetic appearance, and depending on the application, the following operations increase the commercial value, and the gist of the present invention is further improved.
The method involves immersing the shell (mainly the nacre) in a strong alkaline solution. The strong alkali is not particularly limited, but is preferably used in foods and cosmetics, so that it does not leave a smell, and sodium hydroxide or potassium hydroxide is suitable. The concentration varies depending on the immersion time, the extent to which the ridge pillar layer remains, and the type of alkali, but is preferably 0.5 to 15%, and the immersion time varies depending on various conditions, but is preferably about 1 hour to 5 days.
After immersion, wash with water. However, even after washing with water well, alkali remains in the nacre, so depending on the application, it may be better to neutralize by immersing in a thin acid aqueous solution for several tens of minutes to several hours. As the acid used here, hydrochloric acid, acetic acid, citric acid and the like can be used.
[0009]
The shell thus obtained is washed with water if necessary, dried and pulverized. The pulverization may be performed by a known method, that is, an apparatus such as a cutter mill, an atomizer or a jet mill.
When the pulverization is made to have a pearly luster, the size of the powder is preferably about 0.05 to 2 mm and pulverized so as to have this size. However, it is difficult to obtain only this size, and after pulverizing the powder of this size to the maximum amount, it may be separated by a sieve or the like. Larger powders may be ground again, and smaller powders may be used in products that do not require pearl luster.
When pearl luster is not particularly required, the degree of pulverization may be determined depending on the application.
If necessary, 0.5 to 2 times the amount of ethanol is added to the pearl oyster pearl layer powder thus obtained and mixed, and after immersion for 30 minutes to several days, it is dried.
[0010]
The nacreous powder of the pearl oyster shell obtained in this way is dyed. There is no particular limitation on the staining method, and a general method may be employed. For example, the pearl layer powder is mixed with water or an organic hydrophilic solvent such as ethanol, methanol, acetone, etc., or a solvent mixed with an organic hydrophilic solvent and water, depending on the intended use, desired staining intensity, and type of dye. Different, dissolve at a concentration of 0.01-1% and leave for 30 minutes to 5 days. When applied to food, the organic hydrophilic solvent is preferably ethanol. In addition, it is preferable to use a highly safe substance such as a natural dye as a dye used for dyeing. Although the pigment | dye to be used is illustrated below, naturally it is not limited to this, The pigment | dye which can be utilized may be limited depending on a use etc.
