Objective Toidentify black rice adulteration by a kind of easy method at home.Methods The method was developed based on the structure and physicochemical properties of black rice anthocyanidins. Because of black rice presented different colors under different alkali circumstance, the adulterated black rice could be identified by qualitative analysis of black rice anthocyanidins. The vinegar and NaHCO3 was added to the treated black rice, respectively.ResultsThe color of black rice presented red in vinegar and blue in NaHCO3, and the reaction is reversible.ConclusionThe adulterated black rice could be identified by an easy method at home.
