摘要:

以草鱼鱼鳞为原料,在低于蛋白变性温度的条件下提取酸溶性胶原蛋白(ASC)和酶溶性胶原蛋白(PSC),并对鱼鳞原料的前处理方法、胶原蛋白提取工艺进行优化。结果表明,在鱼鳞原料的前处理工艺中,以0.1mol/L 的Na2CO3 溶液为试剂脱除原料中杂蛋白的最佳工艺条件为室温、料液比1:40(g/mL),300r/min 搅拌处理3 次,每次6h;以0.3mol/L 的EDTA 为试剂脱除原料中矿物质杂质的最佳工艺条件为室温、料液比1:60,搅拌处理3 次,每次12h;ASC 的最佳提取工艺条件为:提取温度不高于25℃,料液比1:60,醋酸浓度0.8mol/L,提取3 次,每次24h;PSC 的最佳提取工艺条件为:胃蛋白酶用量为鱼鳞原料质量的3.0%、醋酸浓度0.8mol/L、料液比1:30、提取温度4 ℃、提取2 次,每次24h。

Abstract:

Acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) were extracted from the scales of grass carp at low temperature, and optimal extraction parameters were explored. The optimal parameters for removing impurity proteins from fish scales with 0.1 mol/L Na2CO3 were material/liquid ratio of 1:40 for mixing 3 times for 6 h each time at room temperature. The optimal parameters for removing mineral impurities with 0.3 mol/L EDTA were material/liquid ratio of 1:60 for mixing 3 times 12 h for each time at room temperature. The optimal parameters for ASC extraction were material/liquid ratio of 1:60 for extraction with 0.8 mol/L acetic acid 3 times for 24 h each time at 25 ℃. The optimal parameters for PSC extraction were amount of pepsin on the basis of the weight of fish scales, 3.0%; acetic acid concentration, 0.8 mol/L; and material/liquid ratio 1:30 for twice extraction at 4 ℃ for 24 h each time.
