摘要
该研究以三文鱼(Salmo salar)加工副产物鱼皮为原料开发了一种海洋源胶原。利用酸法提取,盐析透析纯化制备胶原,通过SDS-PAGE和光谱鉴定其结构,在此基础上分析其理化性质、流变特性、功能特性以及细胞相容性。结果表明,三文鱼鱼皮胶原为典型Ⅰ型胶原,且保留了完整的三螺旋结构。鱼皮胶原热变性温度为22.3℃;鱼皮胶原乳化性为65.91~755.97 m^(2)/g,高于牛皮胶原(28.4~56.2 m^(2)/g)和鲵肌浆蛋白(0.6~3.38 m^(2)/g);乳化稳定性为3.50 min,高于蒙古牛骨胶原(0.8 min)和军曹鱼鱼皮胶原(0.2 min),可作为乳化剂用于面包生产;起泡性为16.56%~77.79%,高于酪蛋白(3.95%~10.15%)和米糠浓缩蛋白(5.2%~10.03%);泡沫稳定性(13%)高于大鲵肌浆蛋白(5%)和牛皮胶原(10%),可用于啤酒、乳制品生产。MC3T3-E1细胞在0.4 mg/mL的胶原溶液中相对增殖率为111.6%,优于罗非鱼鱼皮胶原。研究表明,三文鱼鱼皮胶原具有替代市场主流胶原产品的开发潜力。
This study aimed to develop a kind of marine-origin collagen from fish skin,which was a by-product of salmon(Salmo salar)processing.The collagen was prepared by acid extraction and purified by salting out and dialysis.Its structure was identified by SDS-PAGE and spectroscopy,based on the physical and chemical properties,rheological properties,functional properties,and cytocompatibility of the collagen were analyzed.The experimental results showed that the salmon fish skin collagen was a typical type I collagen and retained an intact triple helix structure.The thermal denaturation temperature of fish skin collagen was 22.3℃,and the emulsification of fish skin collagen(65.91-755.97 m^(2)/g)was higher than that of bovine collagen(28.4-56.2 m^(2)/g)and salamander myosin(0.6-3.38 m^(2)/g),and the emulsification stability(3.50 min)was higher than that of Mongolian bovine collagen(0.8 min)and cobia fish skin collagen(0.2 min),which could be used as an emulsifier for bread production.The foaming property(16.56%-77.79%)was higher than casein(3.95%-10.15%)and rice bran protein concentrate(5.2%-10.03%),and the foam stability(13%)was higher than salamander muscle plasma protein(5%)and bovine hide collagen(10%),which could be used for beer and dairy products production.The relative proliferation rate of MC3T3-E1 cells in 0.4 mg/mL collagen solution was 111.6%,which was better than tilapia skin collagen.Therefore,salmon skin collagen has the development potential to replace the mainstream collagen products in the market.
