Application:

 

1. Cosmetics

In human skin, tyrosine, catalyzed by tyrosinase, reacts with oxygen free radicals through complex oxidation and polymerization, and finally synthesizes melanin. Kojic acid can inhibit tyrosinase synthesis, so it can strongly inhibit the formation of skin melanin, and is safe and non-toxic, and does not produce leukoplakia sequela. Kojic acid has been incorporated into make-up water, facial mask, emulsion and skin cream. It can be used to treat freckles, senile plaques, pigmentation, acne and other high-grade whitening cosmetics effectively. Kojic acid at a concentration of 20 ug/ml inhibited 70-80% of the activity of tyrosinase (or PPO), which was generally added in cosmetics at a dosage of 0.5-2.0%.

2. Food Processing

Kojic acid can be used as food additive to preserve freshness, preserve and resist oxidation. Experiments show that kojic acid can inhibit the transformation of sodium nitrite into carcinogenic nitrosamines in bacon, and the addition of kojic acid in food will not affect the taste, aroma and texture of food; kojic acid is also the raw material for the production of maltol and ethyl maltol, and kojic acid is widely used in food processing.

3. Medical Field

Kojic acid has no mutagenic effect on eukaryotic cells, but also eliminates the internal free radicals and enhances the motility of white blood cells. It is beneficial to human health. Therefore, kojic acid has been used as raw material of cephalosporin antibiotics. The finished products produced by kojic acid are used to treat headache, toothache and local inflammation. The analgesic and anti-inflammatory effects are very ideal.

4. Agriculture Field

Kojic acid can be used to produce biological pesticides. Adding 0.5-1.0% kojic acid to bio-micronutrient fertilizer (dark red liquid), whether sprayed as foliar fertilizer at low concentration or as root fertilizer, this crop production promoter has obvious yield-increasing effect on grain and vegetables.

5. Other Fields

 

Kojic acid can also be used as iron analysis reagent, film plaque remover and so on.
