PROBLEM TO BE SOLVED: To provide a water-soluble, glycine-rich protein derived from fish, having no fishy smell and non-gelling property.SOLUTION: Provided is a protein derived from salmon nasal cartilage, which contains 30% or more of glycine (molar ratio in the total amino acids), 15% or more of hydroxyproline and proline together, and has a molecular mass of 10,000 or larger. This protein is obtained by treating salmon nasal cartilage with acetic acid to extract crude proteins, and then collecting the fraction permeated through ultrafiltration membrane of which molecular weight cut off is 100,000. The protein is a water-soluble protein having no fishy smell and non-gelling property.COPYRIGHT: (C)2014,JPO&INPIT【課題】魚類由来のグリシンを多く含む水溶性のタンパク質で、魚臭がなく、ゲル化しない性質を有する。【解決手段】グリシンを全アミノ酸のモル比で30%以上、及び、ハイドロキシプロリンとプロリンの合計が15%以上含み、分子量1万以上である鮭鼻軟骨由来のタンパク質。本タンパク質は、鮭鼻軟骨から酢酸で粗タンパク質を抽出し、分画分子量10万の限外ろ過膜の通過液を集めることにより得られる。本タンパク質は、水溶性であり、魚臭がなく、ゲル化しない性質を有する。【選択図】図1
