PROBLEM TO BE SOLVED: To provide a biodegradable lure made from a natural raw material, equipped with tearing strength and heat resistance of enduring practical uses and solving a problem of the decrease of the tearing strength caused by swelling with water absorption.SOLUTION: This biodegradable lure consists mainly of gelatin gel having &ge4.0 mPa s viscosity measured in accordance with the JIS K6503. Or, it is formed as a gelled material of a gelatin composition containing at least one kind of a cross-linking component in epoxy cross-linking agents and aldehyde cross-linking agents and the gelatin, or it consists mainly of the gelatin-gelled material cross-link-treated with the above cross-linking agent, and some non-melted substance remains in molten gelatin in the measurement of the viscosity in accordance with the JIS K6503.COPYRIGHT: (C)2008,JPO&INPIT【課題】天然素材製で、実用に耐える引き裂き強度及び耐熱性を備え、吸水膨潤による強度低下による問題が解決された生分解性疑似餌を提供する。【解決手段】生分解性疑似餌は、JIS K6503に準じて測定される粘度が4.0mPa・s以上となるゼラチンゲル化物を主成分とする。又は、エポキシ架橋剤及びアルデヒド架橋剤のうちの少なくとも一種の架橋成分とゼラチンとを含有するゼラチン組成物のゲル化物で形成されるか、上記の架橋剤で架橋処理されたゼラチンゲル化物を主成分とし、JIS K6503に準じた粘度測定において融解ゼラチンに不融物が残存する。【選択図】なし
