摘要: 为开发和利用诺丽果资源,本研究将诺丽果浆分别进行非热烫和热烫处理,然后室温密封发酵,观察发酵过程中总糖、总酸、总酚含量和SOD酶活性的变化,同时测定发酵样品对DPPH自由基的清除率。结果表明,随着发酵的进行,总糖含量逐渐下降,总酸含量逐渐提高,总酚含量在发酵过程中保持在0.1~0.2 mg/mL。在第11天时,非热烫和热烫处理样品的DPPH自由基清除率分别达到86.96%和90.19%,同时均具有SOD酶活性。研究结果说明诺丽果浆发酵产物具有抗氧化活性,为功能酵素产品的开发提供参考。

Abstract: The noni pulp was treated without and with hot water, respectively, sealed and ferm ented at room temperature for developing and utilizing noni resource. The changes of total sugar content, total acid content, total phenol content and SOD activity were observed, and the DPPH radical scavenging rate was determined. The results showed that the total sugar content decreased and the total acids content increased during fermentation. The total phenol content was maintained at 0.1-0.2 mg/mL. At the 11th day of fermentation, DPPH radical scavenging rates of samples without and with hot water treatment reached 86.96% and 90.19%, respectively. The SOD activity was also detected in both samples. The research results showed that the fermented product of noni pulp had antioxidant activity and it provides reference for developing functional fermented enzyme products development.
