| Abstract: | Antioxidant activity component and DPPH free radicals scavenging active were studied by four kinds of apple cider vinegar samples of the different fermentation process.The results showed that apple cider vinegar had a higher antioxidant activity,the contents of total phenol,flavones were 2.14 mg/mL,2.19 mg/mL in solid-state fermentation apple cider vinegar,respectively.DPPH free radicals scavenging reached 92.37% when the concentration of apple cider vinegar was 200 μg/mL.There were significant relationships between the contents of total phenol,total flavones and DPPH free radicals scavenging.The correlation coefficients were 0.875 8 and 0.872 3. |
