摘要: 旨在建立海马寡肽的制备工艺,探究寡肽的抗氧化活性。采用酶解法将海马原料制备成海马蛋白酶解肽,将游离氨基酸含量、DPPH·清除率及还原力作为考核指标,在获得制备海马酶解寡肽的最佳蛋白酶的基础上,选取酶添加量、pH、酶解温度及时间为因素,通过单因素和正交试验设计制备海马蛋白酶解肽,对其酶解工艺进行优化。最终获得海马抗氧化活性肽的最佳工艺条件为:风味蛋白酶添加量6000 U/g,酶解温度45℃,酶解时间9 h;在此工艺条件下,酶解产物的游离氨基酸含量为4.198 mg/mL,DPPH·清除率为92.758%,还原力为1.091。试验获得制备海马抗氧化活性肽最优酶解工艺,为进一步研发成保健食品提供坚实的基础。

Abstract: The enzymatic hydrolysis parameters for preparation of antioxidant peptide from seahorse protein were optimized. Base on the results of single factor experiment, content of free amino acids, reducing power and scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical were chosen as the measure indexes, the influences of enzyme species, pH value, enzymolysis temperature, reaction time and enzyme in solid matter for enzymatic hydrolysis were inspected. Optimum hydrolysis conditions were confirmed as enzyme in solid matter, 6000 U/g; enzymolysis temperature, 45℃; and reaction time, 9 hours. Content of the free amino acids, reducing power and scavenging activity on DPPH radical under optimum conditions was 4.198 mg/mL, 92.758% and 1.091, respectively. The optimum hydrolysis conditions were generated and laid a solid foundation for the development of health care products.
