PROBLEM TO BE SOLVED: To provide a conjugated linoleic acid isomer which can be purified in a high purity and a high yield and can be used for food applications, particularly c9, tl1-conjugated linoleic acid and t10, cl2-conjugated linoleic acid isomers (free form and glyceride ester form) ) Is provided. SOLUTION: In the presence of a lipase, a fatty acid mixture or a glyceride ester mixture containing a mixture of conjugated linoleic acid isomers as a constituent is subjected to a selective reaction (hydrolysis or hydrolysis) to conjugated linoleic acid isomers in a reaction system containing no organic solvent. A method for purifying a conjugated linoleic acid isomer, which is subjected to an esterification reaction). A glyceride containing 70% or more of the total content of both isomers of c9, tl1-conjugated linoleic acid or t10, c12-conjugated linoleic acid in the ester obtained by the above method. A food containing fat and a health component (margarine, cheese, sauce, etc.), wherein the health component is one or more of the above-mentioned conjugated linoleic acid isomers (free form and glyceride ester form).
