Hello everyone. Please i need an explaination on antioxidant assay using Beta carotene. Preferably Miller, 1971 method. Publication on this will be appreciated.
dear Tolulope Okanlawon , The bleaching test of β-carotene is based on the loss of β-carotene's yellow color due to its reaction to radicals generated by acid oxidation linoleic as an example in an emulsion, this reaction is followed by spectrophotometery at 470 nm. However presence of an antioxidant could neutralize free radicals derived from acid linoleic acid and therefore prevent the oxidation and bleaching of β-carotene.
