钝顶螺旋藻酶解条件的优化

Optimization of Enzymatic Hydrolysis Conditions for Spirulina platensis

以钝顶螺旋藻(Spirulina platensis)为研究对象,运用蛋白酶SM98011酶解螺旋藻粗蛋白提取液,得到具有抗氧化活性的产物。结果表明,钝顶螺旋藻酶解的最优条件为加酶量1∶15、酶解温度50℃,酶解时间5 h。在此条件下,螺旋藻酶解产物的清除自由基能力为33.28%。

Taking Spirulina platensis as research object, crude protein extract was hydrolyzed with protease SM98011 to obtain antioxidant substances. The results showed that the optimum conditions for enzymatic hydrolysis of Spriulina platensis were as follows： the addition quantity of 1 ： 15, enzymatic hydrolysis at 50℃ for 5 h. Under these conditions, the scavenging capability of enzymatic hydrolysate of Spirulina platensis to free radicals was 33.28%.
