<P>PROBLEM TO BE SOLVED: To provide a method for producing an antioxidant dipeptide of an animal essence by which carnosine and anserine in the antioxidant dipeptides of a functional component inhibiting the aging of human beings can be mass-produced. <P>SOLUTION: The method for producing the antioxidant dipeptide comprises preparing the animal essence regulated so that the pH is 5.0±0.5 and the electrical conductivity is 10±2 mS/cm, bringing the essence into contact with a cation exchanger to allow the antioxidant dipeptide contained in the animal essence to be adsorbed on the cation exchanger, cleaning the cation exchanger having the adsorbed antioxidant dipeptide with a buffer solution and pure water, flowing or mixing an alkali solution of pH8-12 in or with the cation exchanger to elute the basified antioxidant dipeptide from the cation exchanger, adding an acid to the basic antioxidant dipeptide of the eluted fraction so that the pH is ≤8, and concentrating and desalting the fraction by using a nanofilter. <P>COPYRIGHT: (C)2009,JPO&INPIT |
