中文摘要: 以马面鱼皮为原料，研究鱼皮的脱脂除杂蛋白工艺。对脱脂除杂蛋白工艺中试剂种类、试剂浓度、料液比、处理时间等因素进行考察。试验结果表明，马面鱼皮脱脂的最佳工艺为：异丙醇溶液为脱脂试剂，浓度15%，料液比为1∶15（g/mL），在40℃时处理25 h，脱脂率达到93.10%；除杂蛋白最佳工艺为：采用NaCl与NaOH溶液联用进行鱼皮除杂蛋白处理，浓度均为0.3 mol/L，料液比1∶20（g/mL），处理25 h，除杂率为31.09%。
Abstract:The pretreatment technology of removing process of fat and impurity proteins from Navodon septentionalis skin were studied.In the process，the operating parameters agent type and concentration，treatment time and solid-to-liquid ratio were investigated.The results showed that the optimal technology conditions for removing fat from Navodon septentionalis skin with 15%isopropanol were material/liquid of 1 ∶15（g/mL）of 25 h at 40 ℃.The optimal parameters for removing impurity proteins from Navodon septentionalis skin with the mixed solution of NaCl and NaOH（the concentrations were all 0.3 mol/L）were material/liquid of 1 ∶20（g/mL）of 25 h.Under these conditions，the degreasing efficiency and impurity proteins removal rate of fish skin were 93.10%and 31.09%，respectively.
