超声预处理微波辅助酶解生产猪血活性肽工艺优化

    Bioactive peptides produced from ultrasonic-pretreated swine blood by microwave-assisted hydrolyzation

    • 摘要: 为了充分挖掘畜禽血液蛋白质资源及开发具有保健功能的血液深加工生物制品,以猪血细胞为原料,在超声波破碎细胞后,利用微波辅助技术,对Alcalase内切酶酶解猪血红蛋白的工艺条件进行了优化。结果表明:当水与血细胞体积比为5:1,超声波功率为300 W时,超声处理25 min后,在功率为500 W的微波中进行酶解,得出最佳酶解条件为:Alcalase内切酶加酶量体积比6.77%,酶解温度54℃,酶解时间11 min,得到血红蛋白的水解度为23.63%,酶解产物大部分为相对分子质量在635.7~1151.1 Da的短肽。该文提供了一种快速提取猪血活性肽的试验方法,在实际生产中具有较好的应用价值。

       

      Abstract: For making full use of livestock blood proteins and developing functional blooding biological materials, swine hemocytes were disintegrated by ultrasonic waves, and hemoglobins were hydrolyzed by Alcalase assisted by microwave. The results showed that the optimum parameters of ultrasonic disintegration were as follows: the volume ratio of water and hemocytes was 5:1, ultrasonic power 300 W, ultrasonic disintegration time 25 minutes. The 500 W microwave was used when hemocytes were hydrolyzed by Alcalase, and the optimum technology parameters were that the enzyme dose was 6.77% of volume ratio, enzymolysis temperature was 54℃ and enzymolysis time was 11 minutes, the degree of hydrolysis of hemoglobin was 23.63%, and the productions were almost oligopeptide with 635.7- 1 151.1 Da. Those could provide a quick extraction method of swine blood bioactive peptide for further study, and it had well value in practical application.
