Abstract
The present invention is intended to provide a method for manufacturing a natural blue pigment that can be used in food products and the like, and the present invention relates to a method for manufacturing a blue pigment, comprising the steps of combining and warming the reaction product of PeCSO and alliinase, an amino acid, and allicin in an aqueous solution. Other embodiments of the present invention include the aforementioned method for manufacturing a blue pigment, further comprising the steps of extracting the reaction product of PeCSO and alliinase with a water-insoluble organic solvent, and allowing the reaction product to further react with an amino acid in an aqueous solution with the resulting component, and subsequently adding allicin to the reaction mixture to develop blue color, as well as the aforementioned method for manufacturing a blue pigment, further comprising the steps of combining the reaction product of PeCSO and alliinase, an amino acid, and allicin in an aqueous solution, and subsequently heat treating these materials before they are warmed.
