A chicken breast-derived plasmalogen composition having an effect of improving cognitive function, and a food composition or supplement for improving and / or improving cognitive function comprising the composition
PROBLEM TO BE SOLVED: To provide safe and stable plasmalogen having improvement effects on cognitive function, foods for improving cognitive function manufactured by adding the same and an effect determination method therefor.SOLUTION: There are provided a plasmalogen-containing composite lipid which is derived from chicken tissues, consists of a purified article of total lipid extracted and separated from the breast meats thereof and of which a protein fraction and a water soluble low molecular fraction which are by-products are removed, and has a chicken breast meats specific constitutional ratio, and a preparation method of an edible PLs composition manufactured by mixing purified plasmalogen with the chicken breast meats specific constitutional ratio and the composite lipid by enzyme treating the composite lipid with phospholipase A1 (PLA1), removing glycerophospholipids containing lyso body and extraction separation removing sphingomyelin, and the plasmalogen composition manufactured by the method is useful as active ingredient for foods for improving cognition function such as supplements for prevention or alleviation of neurodegeneration disorders and/or psychosexual disorders.SELECTED DRAWING: Figure 4
