超声波处理对发芽糙米GABA积累及抗氧化能力影响的研究

Study on effect of ultrasonic treatment on GABA accumulation and antioxidant capacity in germinated brown rice

  • 摘要: 以有机糙米为材料,利用不同超声波处理时长、频率在糙米萌发不同阶段进行处理,探讨促进发芽糙米中抗氧化成分积累的较优超声波处理条件。结果发现,在发芽前期(0~16 h)进行超声波处理会显著促进GABA的积累,优于在发芽中后期(16~32 h)累积效果、且在相同时长处理情况下,低频率超声波处理对GABA含量的积累优于高频处理。同时在发芽期间进行超声波处理会提高多酚提取量,处理过的发芽糙米清除羟基自由基效果是普通发芽糙米的1.3倍,超氧阴离子清除能力比前者高10.34%。 

     

    Abstract: Using the organic brown rice as material,the effects of different ultrasonic treatment on the accumulation of GABA were studied and the appropriate ultrasonic treatment conditions were discussed,with different length of time and different frequencies of ultrasonic treatment being applied during several period of germinated brown rice growth. Result showed that during the early stage of germination(0 to 16 hours),ultrasonic treatment could have better contribution to the GABA accumulation than the middle(16 to 32 hours). In addition,using ultrasonic treatment during germination might increase the content of polyphenol. The ability to clean hydroxyl radicals of germinated brown rice which was treated by ultrasonic was 1.3 times greater than the one without ultrasonic treatment and the ability to clean superoxide anions was 10.34 percent better than the one without ultrasonic treatment.
