Kojic acid is a chelation agent produced by several species of fungi, especially Aspergillus oryzae, which has the Japanese common name koji.Kojic acid is a by-product in the fermentation process of malting rice, for use in the manufacturing of sake, the Japanese rice wine. It is a mild inhibitor of the formation of pigment in plant and animal tissues, and is used in food and cosmetics to preserve or change colors of substances. It forms a bright red complex with ferric ions.

Technical products and impurities

Kojic acid is commercially available at a purity greater than 98.0% and as a solution

for spraying (TCI America, 2000; Tokyo Kasei Kogyo Co., 2000). Impurities may

include heavy metals (10 mg/kg max.) and arsenic (4 mg/kg max.) (Jarchem Industries,



Methods for the analysis of kojic acid in commercial foods, flavouring compounds,

cosmetic products and microorganisms have been reported. These methods include

voltammetry, spectrophotometry, column chromatography with ultraviolet detection,

thin-layer chromatography, gas chromatography with or without flame ionization,

electron capture or mass spectrometry detection, and high-performance liquid chromato-

graphy with photodiode-array or ultraviolet detection



Kojic acid is a natural antibiotic agent obtained from koji malt (Aspergillus oryzae).

Koji malt has been used for the production of miso, soya sauce and sake in Japan for a

long time (Budavari, 2000; Jarchem Industries, 2000).

Information available in 2000 indicated that kojic acid was manufactured by two

companies in China and one company each in Japan, Switzerland and the USA

(CIS Information Services, 2000).


Kojic acid can act as a tyrosinase inhibitor (to inhibit melanin formation), an anti-

oxidant, a bacteriostat, a metal chelating agent and an intermediate in synthesis. Appli-

cations of kojic acid include the prevention of discolouration of crustacea, meat and

fresh vegetables, as a preservative, as an antioxidant for fats and oils, in cosmetics (skin

whitening or depigmenting agent), in the preparation of derivative esters (i.e. kojic

oleate, kojic stearate), in adhesives, in chelate-forming resins and as a plant growth
