摘　　要：以钙离子溶出量和羟脯氨酸溶出量为评价指标,研究了HCl对鳙鱼鱼鳞脱钙效果的影响。结果表明:低浓度HCl会增加鱼鳞中羟脯氨酸的溶出量;随着HCl浓度、浸酸时间和料液比的增加,钙离子溶出量显著增加,再逐步呈现平稳趋势。文中还比较了脱钙前后鱼鳞的表面结构:结果表明,脱钙前鱼鳞因羟基磷灰石等无机矿物质的附着呈白色粗糙紧致状,脱钙后的鱼鳞呈透明状,网络结构清晰突出,有利于后期提取中胶原蛋白的溶出。Calcium and hydroxyproline dissolving amounts were used as evaluation index to study the effect of hy- drochloric acid decalcification on fish scale. The results indicated that hydrochloric acid with low concentrations could improve the hydroxyproline dissolving amounts. With the increment of hydrochloric acid concentrations, pickling time and solid-liquid ratio, the calcium dissolving amounts were increased significantly at first and then became stable. The surface structures of scales before and after decalcification was compared. The results showed that scales without de- calcification were rough white due to adhesion of hydroxyapatite. However, scales with decalcification were transpar- ent and had a prominent network structure which would be favorable for collagen extraction later on.
