Kojic acid, also known as aspergillic acid, kojic acid, is a melanin specific inhibitor, it can enter the skin cells and copper ions in the cell complexation, change the three-dimensional structure of tyrosinase, prevent tyrosinase activation, thus inhibiting the formation of melanin. Kojic acid whitening active agents have better tyrosinase inhibition effect than other whitening active agents. It does not act on other enzymes in the cell, no toxic effect on the cell, at the same time it can enter the interstitium, the formation of intercellular glia, play the role of water retention and increase the elasticity of the skin. It has been used in various cosmetics to make whitening cosmetics for freckles, age spots, hyperpigmentation and acne.
Kojic acid also has the function of scavenging free radicals, enhancing cell vitality, food preservation and color protection, and is widely used in medicine and food fields.

Application
* Cosmetics field
Kojic acid can inhibit the synthesis of tyrosinase, it can strongly inhibit the formation of melanin in the skin. Safe and non-toxic, and will not produce sequelae of white spots.
It can effectively treat freckles, age spots, pigmentation, acne, used to add to other high-end whitening cosmetics.
Kojic acid at a concentration of 20ug / ml can inhibit the activity of 70 to 80% of a variety of tyrosinase (or polyphenol oxidase PPO), and it is generally added in cosmetics at 0.5 to 2.0%.
*Food field
Kojic acid can be used as a food additive, which has the functions of preservation, antiseptic and anti-oxidation. Experiments have shown that kojic acid can inhibit the conversion in bacon to carcinogenic nitrosamines, and that the addition of kojic acid to foods will not affect the taste, aroma and texture of foods; kojic acid is also the production of maltol and ethyl maltol raw material.
*Medicine field
Since kojic acid has no mutagenic effect on eukaryotic cells, it can eliminate the free radicals in the human body and enhance the leukocyte dynamics, which is beneficial to human health. Therefore, kojic acid has been used as a raw material for cephalosporin antibiotics. Headache, toothache and local inflammation are ideal for analgesic and anti-inflammatory effects.
*Agrucultural field
Kojic acid can be used in the production of biological pesticides. Bio-fertilizer (dark red liquid) made by adding 0.5 ~ 1.0% kojic acid, whether it is sprayed at low concentration as foliar fertilizer, or produced as a growth-increasing agent for root application, this crop production promoter is effective for grain and Vegetables have obvious effects of increasing yield
