PROBLEM TO BE SOLVED: To solve a problem that a phytic acid has been used in such a field as food, medical and the rust prevention of metal as a chelate agent, a preservative agent or the like, however, a phytic acid solution is colored in gray in a short period of time and day, a dark brown deposit is generated, chelation ability is also deteriorated, and the browned dark-brown phytic acid solution which is limited in use, in particular, in a food field from view points of the deterioration of its effect and coloring performance.SOLUTION: The powdery composition existing in a state that the phytic acid is closely adhered to sodium acetate powder is hardly changed in color even after storage for six months or longer, and a phytic acid-natrium acetate solution can be obtained by using the powder as a solution in use. By adding the powdery phytic acid composition to food having a specific odor and fishy smell such as, in particular, butcher meat, bird meat, fish and shellfishes, plant protein, fat an oil, or a fat/oil containing food, these odors are suppressed, a favorable flavor can be imparted to the food, and an effect for enhancing quality can be obtained.
