Abstract
The invention provides a method for establishing a separable regeneration system for verifying regeneration effect between two antioxidants, which belongs to the field of regeneration effect of antioxidants. According to different solubilities of two antioxidants, lipid-soluble antioxidant is first combined into PE film, and water-soluble antioxidant is dissolved into deionized water and a separable regeneration system where antioxidants can contact with other but not dissolve in each other is formed. This method compares the differences of change of antioxidant capacity in aqueous phase with and without lipid-soluble antioxidant so that to judge whether the added lipid-soluble antioxidant has regeneration effect on aqueous-soluble antioxidant. The present invention effectively verifies the regeneration effect between different antioxidants, and has advantages of simple operation, less interference factors, intuitive and high efficiency.
