3.3.2 How Ferric-reducing antioxidant power (FRAP)By FRAP leaching preparation from acetate buffer solution (pH 3.6), 10 mM in TPTZ.Concentrated HCl 40 mM and Ferrous chloride aqueous solution concentrated 20 mM in a 10: 1 ratio: 1 (v/v)Respectively. The new ngatriam FRAP ตอ้ aqueous solution every time before use ngan and NA. Hot tub to the control.The temperature at 37 degrees Celsius. Before it is implemented.In this way, the test will be used to extract 50 microliter volumes closely, Asian and Western cuisine. Additional FRAP solutionVolume 1.5 ml mixing กนั บ็ door hinges to provide high sensitivity in the dark for a period of time, 4 minutes to suck metrics.593 nm light. By comparison with a standard graph of Ferric sulfate solution with.Concentrations in the range of 100-2000 μ M. To do this, repeat the three trials and averages.
