摘要: 本文用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)法,测定了明胶的α组份含量,用胶冻强度测定仪测定了它们的强度.表明:这两种数据的比值呈线性的对应关系.作者曾在“α1组份含量最高的明胶”一文[1]中推测,胶冻强度与明胶α组份含量之间存在相互的影响,这一推测在本文的研究中得到证明.

关键词: 明胶, 胶冻强度, 组份

Abstract: In this paper seven samples were collected,which differ greatly from each other in physical property.The content of α component was determined by SDS PAGE method.The gel strength of gelatin was determined by gel strength instrument.An attempt was made to correlate between these two characteristics.It was shown that there is a very good linear relationship between the content of α component and gel strength.The α component content is considerde to be the main factor affecting the gel strength of gelatin.

Key words: gelatin, gel strength, component
