摘　　要：利用微波法水解动物蹄角制备复合氨基酸,通过正交试验来研究动物蹄角中制备氨基酸过程中的工艺条件及优化。正交试验获得氨基酸提取的最佳工艺条件为微波功率低档,硫酸浓度2.5 mol/L,水解温度120℃,水解时间8 h。微波水解法与常规水解法相比,具有水解时间短,水解率高的优势。Animal toenail was used to prepare composite amino acid.To optimize the process for extracting amino acid from animal toenail was studied by orthogonal experiment. The result of orthogonal experiment showed that the optimal extracting animal toenail was low intensity of microwave,2.5 mol/L sulfuric acid ,the temperature at 120 ℃,extracting 8 h.The results indicateted that Microwave-hydrolyzing process was effective and the hydrolyz ing time was shortend.
