摘要/Abstract

摘要： 本文介绍了有关鱼明胶的新的研究.用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)法检测,从鱼鳔中提取的明胶的α₁组份的含量可达到总组份含量的50%以上.这是迄今为止所发现的α₁组份含量最高的明胶,它大大超过了国际IAG骨明胶的α₁组份的平均含量.鉴于α₁组份对明胶的胶冻强度具有决定性的作用.因此,这一发现对于推广鱼明胶的应用具有重要的意义.

关键词: 鱼明胶, 鱼鳔, 分子量

Abstract: Isinglass is a kind of gelatin made from fish swim bladder and can be used in many fields,which introduces the new study of isinglass. A few fish gelatin samples were prepared by enzymatic method. SDS-PAGE method indicates the content of α₁ conformations of isinglass, which was made from swim bladder. The capacity is above 50%, which is much higher than that of bone processed. Concentration of α₁ gelatin is much higher than the international IAG gelatins. In view of the decisive effect on gel strength of gelatin.This discovery has an important significance for expanding the applications of isinglass.

Key words: fish-gelatin, swim bladder, molecular weight
