Kojic acid  also has the functions of scavenging free radicals, enhancing cell viability, food preservation and color protection, and is widely used in the fields of medicine and food.

Function
(1) Kojic acid is a weak acid compound produced by glucose metabolism during the growth of some microorganisms.
(2) It existed in sauce and wine since ancient times.
(3) Kojic acid is similar to glucose in structure. Isotopic experiments have proved that glucose is formed by oxidation and dehydration without breaking of carbon frame.
(4) Kojic acid can be detected in all fermentation products of aspergillus fermentation.
Kojic Acid (5-hydroxy-2-hydroxymethyl-4-pyrone) is a by-product in the fermentation process of malting rice. Mild inhibitor of the formation of pigment in plant and animal tissues, used also to preserve or change colors in food and cosmetics. Off-white powder. Soluble in water.

Application
1. Applied in the field of cosmetics. In human skin, tyrosine undergoes complex oxidation and polymerization with oxygen radicals under the catalysis of tyrosinase, and finally melanin is synthesized. Kojic acid can inhibit the synthesis of tyrosinase, so it can strongly inhibit the formation of melanin in the skin, and it is safe and non-toxic, and does not produce leukoplakia sequelae. Therefore, kojic acid has been formulated into lotion, mask, lotion and skin cream. It can effectively treat high-grade whitening cosmetics such as freckles, age spots, pigmentation and acne. Kojic acid at a concentration of 20ug/ml can inhibit 70-80% of the activity of various tyrosinases (or polyphenol oxidases PPO), and the amount of addition in cosmetics is generally 0.5-2.0%.

2. Food processing. Kojic acid can be used as a food additive to maintain freshness, antisepsis and anti-oxidation. Experiments have shown that kojic acid can inhibit the conversion of into carcinogenic nitrosamines in bacon, and the addition of kojic acid in food does not affect the taste, aroma and texture of food; kojic acid is also the production of maltol and ethyl maltol. Raw materials, in food processing, kojic acid has a wide range of applications.

3. The field of medicine. Because kojic acid has no mutagenic effect on eukaryotic cells, it can eliminate free radicals and enhance white blood cell kinetics in human body, which is beneficial to human health. Therefore, kojic acid has been used as a raw material for cephalosporin antibiotics, and the finished drug is used for treatment. Headache, toothache and local inflammation are ideal for analgesic and anti-inflammatory effects.
4. In the agricultural field. Kojic acid can be used to produce biopesticide. Adding bio-fertilizer (dark-red liquid) made of 0.5-1.0% kojic acid, whether it is sprayed at a low concentration as a foliar fertilizer, or made into a growth-increasing agent for root application, this crop production accelerator for food and Vegetables have obvious yield-increasing effects.
5. In other fields. Kojic acid can also be used as an iron analysis reagent, a film spotting agent, and the like.
6, kojic acid and its derivatives are used as a whitening agent in the cosmetics industry, but also play a role in anti-corrosion and moisturizing. In the food industry, kojic acid is used as a food additive, as a preservative, preservative and color protectant, and as a raw material for the preparation of the flavoring agents maltol and ethyl typh. It can also be used to produce intermediates for cephalosporin antibiotics. It can also be used to produce pesticides and pesticides.
7. Kojic acid and its derivatives, such as acetate, have certain antibacterial properties, no one-time stimulation and cumulative stimulation on the skin, and can be used as a preservative for cosmetics and food. It can absorb ultraviolet light strongly and can be used alone or in combination for various sunscreen products such as soap. It can treat and prevent the formation of skin spots such as liver spots, and the effect is obvious at 1%~2.5%. Helps maintain humidity and reduce skin wrinkles. Add dandruff to the hair supply.
