【発明の属する技術分野】
本発明は、コンニャクマンナンを素材とした生分解性擬似餌を食用色素で着色した後、有機酸緩衝液に浸漬処理し、色素を着色固定化することによって保存安定性並びに水中での溶出安定化をはかることによって環境に優しい、しかも取扱い易く色素の長期保持性のある生分解性似餌の提供に関する。
【0002】
【従来の技術】
今日のレジャーブームとあいまって趣味、娯楽の中でも釣りが幅広く大衆化してきた。中でもその使いやすさ、手軽さ等から幅広い年齢層でルアー(擬似餌)の使用が一段と増してきている。一方このブームの加熱で使い捨てのルアーが魚体内にそのまま残ったり、根がかり等により放置されたルアーと共に残った釣り糸が水鳥の足に絡まったりする事故が相次いでいる。こうした環境への悪影響を改善するため自然界で微生物によって分解される生分解性擬似餌が注目されている。
例えば、特開昭62ー190037号公報には多糖類と多価金属化合物を基材とする擬似餌用ゲル化組成物が開示されており、動物性真餌に近いものではあるが、水中叉は海水中での使用に耐える形態保持や安全性、特に魚類群誘引物質の中でも誘引効果を左右する色素の保持性に劣っている。
また、特開昭63ー120366号公報にはコンニャクマンナンを主成分とするコンニャク芋精粉に蚕蛹粉末等の魚類群誘引物質、着色料等を混合添加し、アルカリ処理により得るゲル組成物に蒸し処理を施した後、各種成型及び/叉は各種包装形態品の釣餌及びその製造方法が開示されている。しかし、コンニャクマンナンの凝固前に着色を施し、アルカリ処理で凝固後蒸し処理によって着色料の安定化をはかっているが根本的には着色料の固定安定化はなされておらず、また凝固前の着色では各種動物性生餌に似せた自由な色の調整は困難であり釣餌としての性能が著しく低下してしまう欠点がある。
【0003】
【発明が解決しようとする課題】
本発明は、生分解性擬似餌を生餌に酷似した着色を長時間保持させることを目的にした着色法において、着色料に食用色素として使用できる法定食用タール色素および/または天然色素を使用して、コンニャクマンナンを素材とした生分解性擬似餌の品質を損なうことなく着色、固定化することを特徴とした安全性の高い自然に優しい着色生分解性擬似餌を提供することにある。
【課題を解決するための手段】
本発明者は生餌に酷似した着色を長時間保持させることのできる着色法について種々検討を重ねた結果、弱アルカリ性に調整した食用色素の水溶液中にコンニャクマンナンを素材とした擬似餌を浸漬して色素を浸透着色させ、更に有機酸とリン酸水素二ナトリウムでpH3.8〜4.5に調整した緩衝液、好ましくはpH4.0〜4.3に調整した緩衝液に浸漬することにより本発明の目的を達成することができる着色法を見出した。
すなわち本発明は、コンニャクマンナンを素材とした擬似餌を凝固後に、弱アルカリ性に調整した食用色素水溶液中に浸漬し、浸透着色した後、有機酸緩衝液に室温で3〜7時間浸漬し色素を固定化する生分解性擬似餌の着色固定化方法である。また本発明は、コンニャクマンナンを素材とした擬似餌を凝固後に、弱アルカリ性に調整した食用色素水溶液中に浸漬し、浸透着色した後、pH3.8〜4.5の有機酸緩衝液に室温で3〜7時間浸漬し色素を固定化する方法で着色固定化された、生分解性擬似餌である。
【0004】
【発明の実施の形態】
以下、本発明の生分解性擬似餌の着色固定化方法について詳述する。
本発明で使用するコンニャクマンナンは最も多く栽培されているコンヤク芋の赤茎種の他、青茎種、シナ種等のいずれでも良く、これらから通常食用コンヤクとして供されるコンニャク芋粉を使用することができる。
このコンヤク芋粉を素材として、これに魚類群誘引物質として蚕蛹粉末、魚油類、魚粉類、魚臭性物質等のような味覚、臭覚刺激物質、蛍光物質のような視覚刺激物質、さらには必要により着色料、防腐剤等を添加混合した後アルカリ処理し、各種動物生餌に似た形状、大きさの型枠で凝固成型して似餌をえる。
本発明に用いられる着色料は、食品添加物として用いられる法定食用タール色素および/または天然色素であり、法定食用タール色素として好適に使用されるものとしては、カラーインデックス番号がC.I.45430(食用赤色3号)、C.I.45410(食用赤色104号)及びC.I.45440(食用赤色105号)などのキサンテン系のものを挙げることができる。また天然色素としてはクチナシ黄色素(クロセチン)、クチナシ青色素及びアナトー色素等を好適に使用することができる。更に望ましくは、これらの法定食用タール色素と天然色素とを適宜配合して使用することが好ましくその濃度、色相を自由に変化、調整することによって各種動物性生餌の色に合わせることができる。
コンニャクマンナンを素材とした生分解性擬似餌の着色はコンニャクマンナンを凝固する前にその他の魚類群誘引物質と共に添加着色することもできるが、望む各種動物性生餌の色に調整するには凝固後着色する方が好ましく、室温で上記色素の弱アルカリ性水溶液に浸漬することによって容易に実施できる。
本発明に用いられる有機酸としては、クエン酸、酒石酸、リンゴ酸及びフマル酸等が挙げられ、特にクエン酸が好ましい。
